Reiskind MH, Griffin RH, Janairo MS, Hopperstad KA. About Europe PMC; Preprints in Europe PMC With regard to dog heartworm disease, this loss of mosquito diversity is associated with decreased heartworm prevalence within both the vector and the host. 2003;40:78594. Public health issues concerning the widespread distribution of canine heartworm disease. Veterinarians reported numbers of patients tested for heartworm infection, as well as the number of positive cases from that total. We found an overall decrease in heartworm disease within the vector in suburban areas and a positive correlation between heartworm disease within the host and mosquito diversity measures, which are lower in suburban areas than in undeveloped areas. 2013;29:4608. quadrimaculatus) are known to be competent heartworm vectors [20]. According to the AHS survey, 82% reported that they follow the AHS guidelines on prevention, diagnosis, and treatment of heartworm disease, while more than half of practitioners utilize resources on the AHS website.

As the percentage of mosquitoes in the area that have previously laid eggs (and therefore previously taken a blood meal) increases, D. immitis presence in mosquitoes also increases, reaffirming that older mosquitoes are the most dangerous from a disease transmission standpoint due to their greater probability of prior pathogen exposure. Acta Trop. We investigated seasonality of D. immitis transmission within Wake County by plotting the overall percent positive pools across the sampling season. All authors participated in editing and review of the manuscript. We also considered that socioeconomic status may affect disease prevalence, hypothesizing that higher income areas have less dog heartworm than low income areas. While we did not detect any differences in heartworm prevalence within mosquitoes based on neighborhood age, it could still be affecting prevalence within the host indirectly by decreasing mosquito diversity, as mosquito diversity metrics decrease as suburban neighborhoods age [10]. Any dogs without heartworm test results or a designated zip code were removed from analysis. Accessed 6 Aug 2018. Effects of landscape anthropization on mosquito community composition and abundance. Studies investigating socioeconomic gradients have variably shown greater mosquito prevalence in lower income neighborhoods [23, 24] and in higher income neighborhoods [25], as well as no effect on mosquito densities [26]. Spence Beaulieu, M.R., Federico, J.L. The qPCR procedure consisted of a denaturation step at 95C for 30s, followed by 40 cycles of denaturation at 95C for 5s, annealing at 60C for 15s and extension at 72C for 10seconds.

Positive pools were confirmed via sequencing, with all pools aligning to a portion of the D. immitis mitochondrion [33]. We've compiled the Heartworm prevalence data from thousands of veterinary clinics to help you work with your veterinarian to protect dogs from Heartworm. 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. 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. Park AW, Cleveland CA, Dallas TA, Corn JL. 364 S 300 E PROVO UT 84606-4706. We collected a total of 10,244 mosquitoes over the two years of sampling. Each dot represents the center of a zip code containing at least one feline heartworm antigen positive. 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. Zip codes where mosquitoes were not sampled are denoted NA. Just under 6000 veterinary practices and shelters submitted data from more than 5.5 million pets. 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. -, Linthicum KJ, Britch SC, Anyamba A. Incidence maps. All zip codes in Wake County had some level of heartworm infection, but zip codes where mosquitoes were not sampled were omitted from visualization (denoted NA) for clarity. 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.

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). Future studies could partner with local veterinarians to get finer scale host data, as collection of detailed travel history for newly heartworm-positive dogs would allow for more definitive mapping of spatial and temporal host-level incidence trends. https://www.heartwormsociety.org/veterinary-resources/incidence-maps. Based upon the increased abundance of suspected vectors, we originally predicted that older neighborhoods with less diverse mosquito assemblages would have greater dog heartworm prevalence, but this was not supported by our findings.

Geospat Health. 12 ISSN: 1756-3305 We acquired median household income by zip code from the 20132017 American Community Survey using U.S. Census Bureaus American FactFinder tool [37] to investigate whether D. immitis prevalence within dogs and socioeconomic status is correlated. PubMed In most cases, the utilization of AHS resources was higher than that reported in the 2013 and 2016 surveys (. Would you like email updates of new search results? Am J Trop Med Hyg. The most prevalent species was Ae. We acquired data from the Wake County Animal Center on all dogs entering the shelter either as an owner surrender or as a captured stray between January 2010 and October 2015. Med Vet Entomol. We performed two KruskalWallis tests to compare heartworm prevalence across land-use types in R 3.5.0 statistical software [35]. 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. CAS Percent parous mosquitoes and percent Dirofilaria immitis-positive mosquito pools were compared for data from the 2015 trapping season.

No relationships were noted between within-mosquito and within-host heartworm prevalence. 2014;11:325670. 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. 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. Within-host heartworm prevalence was well modeled by mosquito diversity and household income, further underscoring the effect of mosquito diversity while also illustrating the importance of socioeconomic status, possibly due to differences in administration of preventative medications. Yet throughout the trapping season, percent D. immitis-positive pools was positively correlated with mosquito parity data. With so many known heartworm vectors spanning across multiple genera, the apparent lack of seasonality coupled with a positive correlation with parity could be due to vector mosquitoes having different phenologies, making heartworm transmission potential a nearly constant risk throughout the warmer months in North Carolina. Dogs at higher risk of contracting heartworm disease from mosquitoes in OC, officials say. The shift in mosquito assemblage to a lower richness community composed of a high proportion of known vectors likely increases disease transmission for most pathogens [9, 15]. #heartworms #pethealth https://t.co/3tjbH, RT @AHS_Think12: MYTH: My dog is on heartworm preventative, so he doesn't need to be tested. Suburban areas had lower within-mosquito heartworm prevalence and lower likelihood of heartworm-positive mosquitoes than did undeveloped field sites, although no differences were seen between suburban and undeveloped wooded sites. 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. 5. Courtesy American Heartworm Society. albopictus. 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. We used this binary designation as an additional method to investigate any detectable relationships between vector infection and host infection in our dataset. The mosquitoes implicated as heartworm vectors within suburban areas in this study were Ps. 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. Since sample sizes varied among species, the number of positive pools and the total number of pools tested per species are provided above each bar, Relationship between mosquito parity and within-mosquito heartworm prevalence. 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. 2009;6:23949.

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. 2022 Nov 3;15(1):407. doi: 10.1186/s13071-022-05514-1. The 2019 estimate dropped slightly to approximately 1.1 million infected dogs. 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. CAS Percent positive pools by species is presented, with bars color-coded to denote the land-use type where the positive pool originated. Apperson CS, Engber B, Levine JF. Wild host densities are not assessed in this study, but could play an important role in the heartworm transmission dynamics for domestic dogs, particularly if wild hosts that typically serve as primary D. immitis reservoirs are excluded from highly urbanized areas. Species-level heartworm prevalence by land-use type. Dr. Duke has special interest in orthopedic and reconstructive trauma surgery. Michael H. Reiskind. While heartworm incidence dropped slightly in some parts of the country in 2019, more veterinarians overall noted an upward trend in heartworm incidence over the previous 3 years than a downward trend. 229 S 300 E PROVO UT 84606-4743. 2016;158:197200. 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]. Harrison XA, Donaldson L, Correa-Cano ME, Evans J, Fisher DN, Goodwin CE, et al. The AHS released the results of the most recent survey, which reflects testing results from the 2019 calendar year. c While the relationship between within-host heartworm prevalence and mosquito rarefied richness was not significant (F(1, 16)=4.342, P=0.054, R2=0.213), a similar positive trend was found.

The https:// ensures that you are connecting to the However, since mosquitoes are responsible for transferring the parasite from dog to dog, some areas do pose a higher risk than others. On one hand, heartworms maintain a stubborn hold in the U.S., with the southeastern U.S. leading the nation in incidence. This information can be utilized to identify areas of high mosquito diversity that may be foci for heartworm transmission. The two variables were positively correlated (Spearmans =0.494, P=0.027).

Land use influences mosquito communities and disease risk on remote tropical islands: a case study using a novel sampling technique. Fully mature adults at 6.5 months after infection reach lengths of 15-18 cm (5-6 in) for males and 25-30 cm (10-12 in) for females. The authors declare that they have no competing interests. Discrimination between six species of canine microfilariae by a single polymerase chain reaction. Although the response is likely different for diseases transmitted by one or few species, mosquito diversity losses leading to decreased transmission could be generalizable to other pathogens with multiple vectors. We investigated this question using the dog heartworm, a filarial parasite vectored by numerous mosquito species. Bookshelf 2022 Jul 11;107(2):231-44. doi: 10.4269/ajtmh.21-0167.

Dr. Carithers also currently serves as vice president of the AHS and president of the American Association of Veterinary Parasitologists. However, there are numerous examples of disease systems in which an assembly of vector species are responsible for pathogen transmission (e.g. Within the canine host, the adult heartworm resides in the pulmonary arteries and the heart, causing respiratory distress and eventually congestive heart failure [17]. Due to low overall numbers of Dirofilaria immitis-positive mosquito pools across all trapping sites, many zip codes had no detected within-mosquito heartworm infection. 6. Sequences were assembled using the Geneious 9.1.8 native de novo assembly algorithm and consensus sequences were generated for each sample. In Mississippi, almost 10% of dogs tested for heartworms were heartworm positive in 2019; in Louisiana, just under 8% of dogs tested were positive. 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. 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. 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. Ae.

Within-mosquito heartworm prevalence throughout the trapping season. The American Heartworm Society (AHS) estimates that only 55% of dogs in the U.S. are currently on a heartworm preventive. He has served on the AHS Executive Board since 2016. 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. 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. Since then, the AHS Heartworm Incidence Survey has been conducted every 3 years, using heartworm testing data submitted by veterinary practices, reference laboratories, and animal shelters.

This could be due to increased preventative medication use in higher income areas [22], or to variation in other factors such as the amount of time a dog spends outside and therefore amount of potential mosquito exposure time. Conclusions: 2020 Feb 27;57(2):608-614. doi: 10.1093/jme/tjz190. 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. 1):607. Despite high rates of urbanization and ample examples of vector-borne diseases transmitted by multiple species, the effects of urbanization-driven mosquito diversity losses on disease transmission has not been well explored. Please enable it to take advantage of the complete set of features! Parasites Vectors 12, 369 (2019). 2, Spearmans =0.494, P=0.027). It is possible that heartworm disease risk could be higher in urbanized areas [21], where the majority of mosquito bites are likely to be from Ae. This agrees with findings from a recent study that demonstrated a negative correlation between human population size and within-host heartworm prevalence [40]. Mosquitoes of the southeastern United States. Preventives for Dogs Since the latter model is a more complex version of the prior nested model that has greater AIC support [38], the model including only mosquito ShannonWiener diversity and median household income is the best predictor of D. immitis prevalence within the canine host. Rishniw M, Barr SC, Simpson KW, Frongillo MF, Franz M, Alpizar JLD. a Heartworm prevalence within dogs ranged from 3.77% to 15.64% within zip codes where mosquitoes were sampled. This study contributes to better understanding of the effects of urbanization and the role of vector diversity in multi-vectored pathosystems. The AHS released the results of the most recent survey, which reflects testing results from the 2019 calendar year. We compared within-mosquito heartworm infection across land-use types by Kruskal-Wallis and likelihood ratio tests. 2003;127:3751. Med Vet Entomol. doi: 10.1146/annurev.ento.54.110807.090626. Additionally, lower socioeconomic status could increase disease risk via increased vector exposure, either through behavioral factors (e.g. Comparative Vector Efficiency of Two Prevalent Mosquito Species for Dog Heartworm in North Carolina. 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. The authors declare that they have no competing interests. Trends Parasitol. Urbanized areas tend to have distinct mosquito communities that are characteristically less diverse than those in natural habitats [9,10,11,12,13]. More broadly, our findings can be generalized to other pathogens with multiple vectors, contributing to an understanding of the role of arthropod diversity in multi-vectored disease systems. An official website of the United States government. There is effective preventative medication that protects dogs from becoming infected with D. immitis, but these medications are by prescription only, requiring not only the cost of the medication but also the cost of routine veterinary care, presenting a financial barrier for some pet owners.
