It is not possible to definitively tell whether the dog acquired the heartworm infection within the zip code of its primary residence, nor is it possible to tell whether the positive heartworm test represents a new or chronic infection due to the long lifespan of the parasite within the host. Menu. J Am Vet Med Assoc. However, since mosquitoes are responsible for transferring the parasite from dog to dog, some areas do pose a higher risk than others. Make an appointment. PubMed Central doi: 10.7554/eLife.22053. We did not find a relationship between log mosquito abundance and within-host heartworm prevalence (F(1, 16)=0.396, P=0.538). At each of the suburban and undeveloped sites, we sampled overnight with CDC light traps (JW Hock Co., Gainesville, FL, USA) baited with 1kg of dry ice (solid CO2). McTier, T.L., Kryda, K., Wachowski, M. et al. He has authored or co-authored 35 peer-reviewed papers, 34 scientific papers, and co-authored a best-selling companion animal parasitology atlas. Species-level heartworm prevalence by land-use, Species-level heartworm prevalence by land-use type. https://orcid.org. Zip code 84604 is located in Provo, Utah. Taken together with the present findings, this suggests that suburban development is decreasing mosquito diversity, and that the resultant decreased mosquito diversity is linked with lower heartworm disease prevalence. In terms of percent D. immitis-positive mosquito pools, Ae. Article We trapped host-seeking mosquitoes in undeveloped areas and neighborhoods of different ages in Wake County, North Carolina, USA, analyzing captured mosquitoes for heartworm DNA. Ecohealth. J Med Entomol. We maximized the likelihood function: where \(y_{i\,j}\) is the binary response of whether pool \(j\) in habitat \(i\) was positive for D. immitis, \(n_{i\,j}\) is the number of mosquitoes in pool \(j\) from habitat \(i\), and \(p_{i}\) is the probability that an individual mosquito in habitat \(i\) is positive for D. immitis. We calculated heartworm prevalence within dogs by zip code in Wake County. 2006;135:30314. canadensis and An. 2022 Jul 11;107(2):231-44. doi: 10.4269/ajtmh.21-0167. Because of their inability to be infectious for D. immitis, we excluded males and nulliparous females from further analysis. CAS Brown HE, Harrington LC, Kaufman PE, McKay T, Bowman DD, Nelson CT, et al. We found that suburban areas generally had the lowest within-mosquito heartworm prevalence, and that mosquito diversity was positively correlated with heartworm prevalence within the canine host. Silaghi C, Beck R, Capelli G, Montarsi F, Mathis A. Parasit Vectors. Exposure to vector-borne pathogens in privately owned dogs living in different socioeconomic settings in Brazil. PLoS Negl Trop Dis. It has been suggested that coyotes are the most significant heartworm reservoirs in North America, with prevalence between 6.5 and 71% nationwide [43] and approximately 47% in North Carolina [44]. We performed real time quantitative polymerase chain reaction (qPCR) to assess for presence or absence of D. immitis DNA within the previously extracted and quantified mosquito pools. Discrimination between six species of canine microfilariae by a single polymerase chain reaction. After excluding males and nulliparous females as previously described, 8483 individuals in 2488 pools were tested for the presence of D. immitis DNA. We also considered that socioeconomic status may affect disease prevalence, hypothesizing that higher income areas have less dog heartworm than low income areas. and canine heartworm (Dirofilaria immitis) in the mosquitoes of Tennessee. However, when analyzing the 2015 data, percent heartworm-positive mosquito pools was positively correlated with percent parous mosquitoes across the trapping season (Fig. Within the canine host, the adult heartworm resides in the pulmonary arteries and the heart, causing respiratory distress and eventually congestive heart failure [17]. We identified all mosquitoes to species using published dichotomous keys [29, 30]. An important factor is that heartworm diagnosis requires one or more blood tests that must be conducted in a veterinary clinic and/or reference laboratory, which limits diagnoses to patients seen in clinics and animal shelters. -, Linthicum KJ, Britch SC, Anyamba A. Modified DNA extraction protocols used with both the DNeasy Blood and Tissue Kit (Qiagen, Venlo, Netherlands) and the ZR Genomic DNA-Tissue MiniPrep (Zymo Research, Irvine, CA, USA). 6. Statistical analyses CAS The 2019 map (. The association between decreased mosquito diversity and decreased heartworm prevalence exists despite the fact that the dominant mosquito species in the sampled suburban areas (e.g. Lights were removed from the CDC light traps to reduce by-catch. No relationships were noted between within-mosquito and within-host heartworm prevalence. Before The effect of urbanization is well known for certain mosquito species of interest, particularly the container-breeding Aedes [7, 8], but has only recently been examined in the context of effects on mosquito species assemblages. Comparison of the vector potential of different mosquito species for the transmission of heartworm, Dirofilaria immitis, in rural and urban areas in and surrounding Stillwater, Oklahoma, U.S.A. Parasites Vectors 12, 369 (2019). dogs spending more time outdoors) or through changes in vector assemblages. No relationships were noted between within-mosquito and within-host heartworm prevalence.

Dr. Carithers also currently serves as vice president of the AHS and president of the American Association of Veterinary Parasitologists. Instead, our results suggest a positive relationship between mosquito diversity and disease transmission, as has been found in the limited existing studies investigating the effects of diversity within disease systems with multiple vectors [5, 6, 16]. The Invasive Mosquitoes of Canada: An Entomological, Medical, and Veterinary Review. Rift Valley fever: an emerging mosquito-borne disease. Mosquitoes show habitat fidelity at a much finer scale of less than 100m [28], leading to a separation of geographical scale between mosquito-level factors and host-level factors that could be obscuring some trends. J Med Entomol. If you are not sure of the full 9-digit ZIP Code, use the 5-digit ZIP Code to avoid loss of letter or package. Following the analysis of survey results, a U.S. heartworm incidence map is generated to provide a visual representation of the spread and severity of heartworm infections. Acta Trop. Previous work with malaria has demonstrated a similar positive relationship between mosquito species richness and disease prevalence [5], suggesting that mosquito diversity losses being linked with decreased disease transmission could be applicable to a variety of multi-vectored diseases. Vet Parasitol. Model selection revealed within-host prevalence was best predicted by a positive relationship with mosquito ShannonWiener diversity and a negative relationship with household income. However, decreases in mosquito diversity after human-driven land-use change could be detrimental when considering other disease systems of concern that are vectored by few mosquito species, such as dengue, chikungunya and Zika with Ae. 2011;26:17885. Am J Trop Med Hyg. Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations. We then tested the null hypothesis that \(\sum p_{i} = p\) using a likelihood ratio test, utilizing the Holm method to correct for multiple comparisons when identifying which land-uses differed in their probabilities. DGE-1746939. If you have been buying prevention from another vet, please attach proof of previous purchases since last heartworm test with name and contact information of the vet it was purchased through. Bockarie MJ, Pedersen EM, White GB, Michael E. Role of vector control in the global program to eliminate lymphatic filariasis. Finally, we performed generalized linear model selection to find the model that best explained within-host heartworm prevalence using all combinations of the following independent variables at the zip code level: presence or absence of heartworm-positive mosquito pools, proportion heartworm-positive mosquito pools, rarefied richness, evenness, ShannonWiener diversity, mosquito abundance and median household income. Of these, 832 tested positive for D. immitis, giving an average prevalence of 10.91% in domestic dogs in Wake County. suggests that there has been little significant. May 16, 2019, 6:04 AM.

We also determined the best predictor of host-level prevalence among models including within-mosquito infection, mosquito diversity and abundance, and socioeconomic status as variables. 2013;10:150526. In 2001, the national estimate for heartworm-positive dogs was just under 900. Google Scholar. Parasit Vectors. At the wooded and field sites, traps were placed at least 100m away from any habitat edge, again consistent with previous findings of mosquito habitat fidelity [28]. ProHeart 6 Pharmacovigilance Data. In addition, participants responded to a brief survey designed to provide insights on factors behind the data. We then pooled parous females by site, date collected and species for molecular analysis, with up to 19 individual mosquitoes per pool. While acknowledging these important caveats, the AHS hypothesized a conservative estimate of heartworm prevalence via the following calculations: Figure 2. PubMedGoogle Scholar. Using zip code level data acquired from dogs in a local shelter, we performed linear regressions of within-host heartworm prevalence by within-mosquito heartworm prevalence as well as by three mosquito diversity measures. Each qPCR reaction consisted of 0.2l each of an established D. immitis-specific COI forward and reverse primer (DI COI primer pair) [32], 5l of SYBR green master mix, 2l of template DNA and 2.6l of water for a total reaction volume of 10l. Parasit Vectors. Another gap in host data is accurate information on wild canid populations that could be serving as reservoirs of dog heartworm. With regard to dog heartworm disease, this loss of mosquito diversity is associated with decreased heartworm prevalence within both the vector and the host. Heartworm disease is a serious disease that results in severe lung disease, heart failure, other organ damage, and death in pets, mainly dogs, cats, and ferrets. This material is based upon work supported by the National Science Foundation Graduate Research Fellowship Program under Grant No. doi: 10.1146/annurev-ento-010715-023819. Annu Rev Entomol. We created categories of neighborhood ages to ensure that neighborhoods of various ages were being sampled: developed before 1993, between 19932002, between 20032007, between 20082012 and from 2013 to present. Vector species richness increases haemorrhagic disease prevalence through functional diversity modulating the duration of seasonal transmission. #heartworms #pethealth https://t.co/3tjbH, RT @AHS_Think12: MYTH: My dog is on heartworm preventative, so he doesn't need to be tested. Similar to our results with within-mosquito prevalence, using the presence or absence of D. immitis within mosquitoes, we did not see a significant relationship to within-host prevalence by zip code (t(8.22)=0.941, P=0.374). https://www.heartwormsociety.org/veterinary-resources/incidence-maps.

Privacy Article Elife. https://factfinder.census.gov/. Bookshelf Eight mosquito species showed evidence of D. immitis infection, with Aedes canadensis having the highest percentage positive pools at 7.7% and the highest MLE infection rate at 29.75 per 1000 individuals (95% CI: 1.79136), followed by Anopheles crucians and Psorophora columbiae both with approximately 2.9% positive pools and MLEs of 26.23/1000 (95% CI: 1.52119.72) and 11.85/1000 (95% CI: 3.8928.05), respectively (Table1, Fig. volume13, Articlenumber:12 (2020) sharing sensitive information, make sure youre on a federal To verify that qPCR pools were positive for D. immitis, all positive amplicons were submitted to Eton Bioscience (San Diego, CA, USA) for Sanger sequencing. Sinka ME, Bangs MJ, Manguin S, Coetzee M, Mbogo CM, Hemingway J, et al. Given the lower probability of D. immitis-positive mosquitoes noted in suburban areas, our focus on sampling mosquitoes predominantly in suburbia could have resulted in lower overall within-mosquito prevalence rates than what has been reported in other studies sampling in more rural landscapes (e.g. Accessed 12 Jun 2019. PubMed To minimize the risk of sample contamination, qPCR was performed at a dedicated workstation that was separate from that utilized for DNA extraction. 2016;143:8749. Every three years, the American Heartworm Society (AHS) gathers data on heartworm testing to understand the impact heartworm is having nationwide, as well as in specific regions. 5. Generally, yes, but the parameters are usually a bit broader. - American Heartworm Society Can Your Zip Code Make Your Dog More Susceptible to Heartworm? 2011;238:3117. We calculated the bias corrected maximum likelihood estimate (MLE) for point estimation of the infection rate of each heartworm-positive mosquito species using PooledInfRate add-in software for Excel [34]. The invasive mosquito species Aedes albopictus: current knowledge and future perspectives. On the other hand, it is clear that there is a straightforward answer to this: persuade more pet owners to use preventives and convince them to protect dogs and cats year-roundwith no lapses.

While Alaska has reported positive dogs in every AHS survey since 2001, to our knowledge, none of those cases. Alabama: University of Alabama Press; 2013. Mean prevalence and standard error of the mean are presented for each land-use type. Mosquitoes used for analysis in this study were previously sampled and the effects of suburban development on mosquito diversity were previously assessed in Spence Beaulieu et al. In addition to suburban sites, we sampled in three natural habitat sites: Schenck Memorial Forest at North Carolina State University (NC State), NC States Equine Educational Unit and NC States Lake Wheeler Beef Unit. Urban and suburban areas throughout much of the USA are dominated by the peridomestic Aedes albopictus, which is a competent vector of D. immitis [20]. PloS ONE. MRSB analyzed and interpreted the data and prepared the original manuscript. Becker B, Leisnham P, LaDeau SL. Many important pathogens are transmitted by a limited number of mosquito vectors, and both research and control efforts have focused on targeting these primary vectors. We found that the best model to predict heartworm prevalence within dogs at the zip code level is one that includes both mosquito ShannonWiener diversity and household income. J Med Entomol. It is believed this change was triggered by drier-than-normal conditions in the western U.S. in 2017 and 2018 that led to lower mosquito populations. Heartworm prevalence is, overall, low in Canada, with endemic transmission occurring seasonally only in regions of southern British Columbia, Manitoba, Ontario, Quebec, and New Brunswick. Article [1,2,3,4]). Ecological drivers of dog heartworm transmission in California. Additionally, lower socioeconomic status could increase disease risk via increased vector exposure, either through behavioral factors (e.g. See this image and copyright information in PMC. Of the total 2488 pools tested, 15 were positive for the presence of D. immitis DNA (Table1).

With regard to socioeconomic status, we found support for our prediction of a negative relationship with heartworm prevalence within the host. Overall, we selected 30 neighborhoods in 2015 that were constructed within the last 40 years and added an additional 6 older neighborhoods in 2016 that were developed between 50 and 102years prior.

For mosquitoes collected in 2015, we sexed the individuals and females were dissected for parity analysis via ovary tracheation [31]. A significant positive correlation was noted between within-host heartworm prevalence and (. & Reiskind, M.H. Each 96-well plate run included one reaction with DNA extracted from a known negative laboratory-reared mosquito combined with a single laboratory-reared D. immitis L3 for the dual purpose of both a positive control and a sensitivity check to ensure D. immitis could be detected down to the presence of a single larva. Infection risk varies within urbanized landscapes: the case of coyotes and heartworm. Interestingly, our previous work in Wake County did not find any effect of socioeconomic status on mosquito diversity measures [10], so the effect of socioeconomic status detected in the present study is likely due to its impact on host-level factors. We analyzed entire mosquito bodies for the presence of D. immitis DNA; because of this, we were unable to distinguish between infected and infectious mosquitoes. Roche B, Rohani P, Dobson AP, Gugan J. LaDeau S, Leisnham P, Biehler D, Bodner D. Higher mosquito production in low-income neighborhoods of Baltimore and Washington, DC: understanding ecological drivers and mosquito-borne disease risk in temperate cities. We performed a logit transformation of our within-host heartworm prevalence data to account for its proportional nature [38], and used Akaike information criterion (AIC) as the estimator of model quality in our model selection. First Name Last Name. Visualization of heartworm prevalence by zip code in Wake County, North. We also found that the probability of an individual mosquito being positive for D. immitis differed between land-uses (LRT statistic =6.40, P=0.041). Terando AJ, Costanza J, Belyea C, Dunn RR, McKerrow A, Collazo JA. 2, Spearmans =0.494, P=0.027). albopictus, versus in natural areas, where bites come from a more diverse mosquito assemblage in which a given species may or may not be a competent D. immitis vector. Among veterinarians who believe heartworm incidence increased, leading reasons cited were an increase in heartworm-positive pets coming from heartworm-endemic areas, poor compliance among pet owners, and weather trends that caused an increase in mosquitoes. Field sites had greater D. immitis prevalence than did suburban sites (Dunns test: Z=2.925, P=0.010), but prevalence at wooded sites did not differ from that at suburban sites (Dunns test: Z=0.630, P=1.0) (Fig. albopictus populations in North Carolina are rare, but have suggested that it is likely not a suitable vector for D. immitis in North Carolina [42]. Ae. Vet Parasitol. Google Scholar. columbiae appears to be a significant contributor to heartworm transmission in suburban Wake County, as it was the only species in the current study to have >1% D. immitis-positive pools in suburban neighborhoods. Despite these limitations, shelter data presents a large, readily available dataset that generally cuts across various human demographics, including income and education levels [45], and is the best data currently available with which to test our predictions. Given that the majority of zip codes had a within-mosquito heartworm prevalence of 0% due to our low number of positive pools, we also performed a Welchs t-test comparing the within-host heartworm prevalence by the presence or absence of heartworm-positive mosquito pools within a given zip code. Using zip code level data acquired from dogs in a local shelter, we performed linear regressions of within-host heartworm prevalence by within-mosquito heartworm prevalence as well as by three mosquito diversity measures. Disease ecology; Diversity; Heartworm; Landscape; Mosquito; Urbanization; Vector. There did not appear to be any seasonal trends in D. immitis infection within mosquitoes, although we could have missed important dynamics in the spring due to our trapping season beginning in June. 2014;11:325670. 1989;5:37782.

Since parity data for mosquitoes were collected only in 2015, we assessed for correlation of parous mosquitoes with heartworm-positive pools in 2015. For both suburban and urban areas generally, anthropogenic disturbance is also associated with increased abundance of vectors of human disease, including container-breeding Aedes that transmit dengue, Zika, or chikungunya viruses, and Culex mosquitoes, which transmit West Nile virus and human filarial pathogens [10, 11, 13, 14].

According to theAmerican Heartworm Society, Mississippi, Louisiana, Arkansas, Texas and Tennessee are the top five worst states when it comes to heartworm diagnosis, in that order. We performed a linear regression of within-mosquito heartworm prevalence versus within-host heartworm prevalence. Urbanization is occurring rapidly on a global scale and is altering mosquito communities, creating assemblages that are characteristically less diverse. We performed two KruskalWallis tests to compare heartworm prevalence across land-use types in R 3.5.0 statistical software [35]. 2018;6:e4794. A 1983 graduate of the College of Veterinary Medicine at Auburn University, Dr. Duke is the founder of the Bienville Animal Medical Center in Ocean Springs, Mississippi. We also sampled at 6 additional smaller parcels of land composed of undeveloped woodlots and 5 additional smaller parcels of land composed of undeveloped fields. We investigated this question using the dog heartworm, a filarial parasite vectored by numerous mosquito species. The 2019 AHS Heartworm Incidence Survey shows that heartworms maintain a stubborn hold in the United States. Of the thousands of U.S. veterinary practices that report testing data to the AHS, a large proportion have reported data from their practice records year after year. ) Park AW, Cleveland CA, Dallas TA, Corn JL. Some preventives only prevent heartworms, some protect pets from heartworms and intestinal parasites, and some protect pets from many different parasites, including heartworms, intestinal worms, fleas, ticks and mites. albopictus as the areas primary vector [21]. Our results demonstrate that anthropogenic land-use change alters vector-borne disease risk. On one hand, heartworms maintain a stubborn hold in the U.S., with the southeastern U.S. leading the nation in incidence.

We thank Paul Labadie, Tommy Pleasant, Hannah Jenkins, Cole Keenan and Dakota Palacio for their work on this project. All pools that were positive for D. immitis DNA were those of mosquito species known to be competent heartworm vectors [20], so we assume that any positive mosquito pool represents potential transmission. Please enable it to take advantage of the complete set of features! When investigating correlations of mosquito diversity metrics at the zip code level to within-host D. immitis prevalence, we detected significant positive relationships for evenness (F(1, 16)=4.881, P=0.042, R2=0.234) and ShannonWiener diversity (F(1, 16)=5.464, P=0.033, R2=0.255) (Fig. This study contributes to better understanding of the effects of urbanization and the role of vector diversity in multi-vectored pathosystems.
