Veterinarians reported numbers of patients tested for heartworm infection, as well as the number of positive cases from that total. However, mosquito diversity metrics were positively correlated with host heartworm prevalence. An ideal system for further examining the effects of mosquito diversity on vector-borne disease transmission is that of the dog heartworm, Dirofilaria immitis. We performed a linear regression of within-mosquito heartworm prevalence versus within-host heartworm prevalence. 2021 Sep 9;14(1):464. doi: 10.1186/s13071-021-04958-1. 2014;4:40933. 2016;61:395415. Parasit Vectors. 2006;135:30314. J Med Entomol. Urban and suburban development is predicted to increase by greater than 100% over the next 50years in the southeastern USA [48], in line with global trends of increasing urbanization. McTier, T.L., Kryda, K., Wachowski, M. et al. We calculated heartworm prevalence within dogs by zip code in Wake County.

Comparative Vector Efficiency of Two Prevalent Mosquito Species for Dog Heartworm in North Carolina. Any dogs without heartworm test results or a designated zip code were removed from analysis. In addition to unmeasured host factors, this study is limited by the spatial scale of the within-dog heartworm prevalence data that we acquired. Comparison of within-mosquito heartworm prevalence by land-use type. 2014;28(Suppl. Mississippi and Louisiana lead the country in heartworm infection rates The five states with the highest incidence of heartworm were Mississippi, Louisiana, South Carolina, Arkansas, and Alabama. 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. Fryxell RTT, Lewis TT, Peace H, Hendricks BB, Paulsen D. Identification of avian malaria (Plasmodium sp.) 2008;45:102330. Parasites & Vectors This study contributes to better understanding of the effects of urbanization and the role of vector diversity in multi-vectored pathosystems. CAS J Med Entomol. and transmitted securely. We calculated mosquito rarefied richness, Pielous evenness and ShannonWiener diversity as previously described [10] and found the average for a given zip code, then performed linear regressions comparing these diversity measures to within-host heartworm prevalence, testing the hypothesis that mosquito diversity impacts heartworm disease transmission. J Am Mosq Control Assoc. In 2001, the national estimate for heartworm-positive dogs was just under 900. We trapped at each site biweekly from June through mid-October in 2015, and June through the end of October in 2016. J Med Entomol. We investigated this question using the dog heartworm, a filarial parasite vectored by numerous mosquito species. 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. Google Scholar. Due to local climate and rainfall, some areas of the country have mosquitoes all year round, so the risk for dogs to contract heartworms is definitely higher than for dogs in hotter, drier areas of the Southwest. Darsie RF. High prevalence of canine heartworm, Dirofilaria immitis, in pet dogs in south Texas, USA, with evidence of Aedes aegypti mosquitoes contributing to transmission. In addition, participants responded to a brief survey designed to provide insights on factors behind the data. J Am Vet Med Assoc. As all sample sequences were identical based on a reference alignment, one sample sequence was used in the MegaBLAST algorithm from the NCBI Nucleotides BLAST suite, returning a positive match to a portion of D. immitis COI with 100% homology (GenBank: AJ537512.1) [33]. Vienna: R Foundation for Statistical Computing; 2018. https://www.R-project.org/. Mosquitoes are a diverse family of flies that can be pests and vectors of medical and veterinary significance, transmitting a wide array of viruses, protozoans and parasitic nematodes to both humans and animals. Accessed 6 Aug 2018. KruskalWallis test was chosen due to the non-normal nature of the data, and Dunns test for multiple comparisons with Bonferroni correction was utilized to identify which land-uses differed in their heartworm prevalence. The second test included neighborhood age categories separately, resulting in seven total treatment levels (wood, field and five neighborhood age categories as previously described). Trends Parasitol. Becker B, Leisnham P, LaDeau SL. While mosquito diversity had a positive relationship with host heartworm prevalence in the model, household income had a negative relationship with host heartworm prevalence, supporting our hypothesis that higher income areas would have less dog heartworm disease than lower income areas. 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. Preventives for Dogs Rounding out the top 10 states were Texas, Tennessee, Georgia, North Carolina, and Oklahoma. Urbanization is occurring rapidly on a global scale and is altering mosquito communities, creating assemblages that are characteristically less diverse. Given the mobility of society today, as well as the need to relocate animals due to natural disasters or animal homelessness, the transport of pet animals is a fact of life in U.S. veterinary practices today. 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. Model selection revealed within-host prevalence was best predicted by a positive relationship with mosquito ShannonWiener diversity and a negative relationship with household income. It was revealed the top 5 states for heartworm incidence were Mississippi, Louisiana, South Carolina, Arkansas, and Alabamaall states that have been in the top 10 states since the AHS began tracking incidence data in 2002. Percent positive pools by species is presented, with bars color-coded to denote the land-use type where the positive pool originated. 2019;14:741. Using an estimate of client base and combining these data with dog numbers from the American Veterinary Medical Association, it is possible to generate a rough estimate of heartworm cases for the U.S. and, more importantly, to track trends. Online ahead of print. 5. 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. Pet relocation. Download : Download full-size image Fig. Springer Nature. We cannot assess spatial trends for D. immitis within mosquitoes due to low overall prevalence (Fig. 2015;51:6649. A brief introduction to mixed effects modelling and multi-model inference in ecology. albopictus, the Asian tiger mosquito, which constituted 41.9% of the overall abundance, followed by Culex salinarius and Aedes vexans with 13.9% and 8.3%, respectively. doi: 10.1146/annurev-ento-010715-023819. We compared within-mosquito heartworm infection across land-use types by Kruskal-Wallis and likelihood ratio tests. Consult the appropriate manufacturer for minimum age/weight, use during breeding/lactation, or other health requirements for product usage. By Sarah Ashley Published May 16, 2019 All 50 states have had confirmed cases of heartworm since the disease's discovery back in 1856. https://factfinder.census.gov/. 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]. 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].

This model was significant, with prevalence positively correlated with diversity and negatively correlated with median household income (DogHWPrev=0.6454 ShanDiv1.035*105 Income2.524; F(2, 15)=6.725, P=0.008, R2=0.473). Within-host heartworm prevalence increases with mosquito diversity measures. Google Scholar. These data contained the results of the heartworm test performed at the time of intake as well as the zip code of the prior owner or location of capture. As detailed in the Methods section, parity data were not collected in 2016 and correlation with heartworm-positive pools was therefore unable to be assessed for the second trapping year. Email. Percent parous mosquitoes and percent Dirofilaria immitis-positive mosquito pools were compared for data from the 2015 trapping season. Contrary to our initial hypothesis, when comparing the land-use types of suburban neighborhoods, undeveloped woodlots and undeveloped fields, we found that field areas had significantly higher prevalence and likelihood of heartworm-positive mosquitoes than did suburban areas. Suburban sites had significantly lower D. immitis prevalence than did undeveloped field sites (Z=2.925, P=0.010). We also considered that socioeconomic status may affect disease prevalence, hypothesizing that higher income areas have less dog heartworm than low income areas. 2010;3:117. Spatial association between malaria vector species richness and malaria in Colombia. Based on the results of a prior study of heartworm prevalence on an urban to rural gradient [21], we hypothesize that older neighborhoods with less diverse mosquito assemblages dominated by Ae.

Mosquito (Diptera: Culicidae) Diversity and Community Structure in Doi Inthanon National Park, Northern Thailand. Within-host heartworm prevalence increases with mosquito diversity measures. eCollection 2022. We then pooled parous females by site, date collected and species for molecular analysis, with up to 19 individual mosquitoes per pool. 2010;26:16873. Land use influences mosquito communities and disease risk on remote tropical islands: a case study using a novel sampling technique. Junglen S, Kurth A, Kuehl H, Quan P, Ellerbrok H, Pauli G, et al. Methods: Parasitology. 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. We thank Paul Labadie, Tommy Pleasant, Hannah Jenkins, Cole Keenan and Dakota Palacio for their work on this project. 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.
