prevalence of dirofilaria immitis and gastrointestinal helminths in cats euthanized at animal control agencies in northwest georgia.cats euthanized at six northwest georgia animal control agencies were examined for adult dirofilaria immitis in heart and lung tissue and presence of gastrointestinal helminth ova by fecal flotation. d. immitis were found in 4 of 184 cats (2.1%). the prevalence of feline dirofilariasis in northwest georgia was lower than that found in other studies conducted in the southeastern united states, but closer to the prevalences occurring in areas of similar topography. heartworm antigen and antibody t ...200415154596
parasitology, virology, and serology of free-ranging coyotes (canis latrans) from central georgia, usa.we examined 31 free-ranging coyotes (canis latrans) from central georgia, usa, for select parasites and viral agents. sixteen coyotes had adult heartworms (dirofilaria immitis). serum samples from 27 animals revealed antibodies against canine parvovirus (100%), canine distemper virus (48%), canine adenovirus (37%), and trypanosoma cruzi (7%); none were detected against leishmania spp. twenty-two of 24 (92%) coyotes were positive for toxoplasma gondii. real-time pcr of feces revealed 32% of coyot ...201425098300
diagnostic, treatment, and prevention protocols for canine heartworm infection in animal sheltering agencies.the high prevalence of heartworm infection in shelter dogs creates a dilemma for shelter managers, who frequently operate with insufficient funding, staffing, and expertise to comply with heartworm guidelines developed for owned pet dogs. the purpose of this study was to survey canine heartworm management protocols used by 504 animal sheltering agencies in the endemic states of alabama, florida, georgia, and mississippi. open-admission shelters, which tended to be larger and more likely to perfo ...201121353743
diagnostic, treatment, and prevention protocols for feline heartworm infection in animal sheltering agencies.cats are at risk for heartworm infection (dirofilaria immitis) wherever the disease is endemic in dogs. diagnosis is more difficult in cats, and little information is available regarding effective palliative and curative treatments for infected cats. in contrast to the challenges of diagnosis and treatment, chemoprophylaxis is highly effective, and current guidelines call for preventive medications to be administered to all cats in endemic areas. the purpose of this study was to survey feline he ...201121330060
use of melarsomine dihydrochloride (rm 340) for adulticidal treatment of dogs with naturally acquired infections of dirofilaria immitis and for clinical prophylaxis during reexposure for 1 year.heartworm-infected dogs were treated therapeutically with a new heartworm adulticide (melarsomine dihydrochloride, rm 340) and then put on a strategic program with treatment every 4 months for clinical prophylaxis to take advantage of the drug's potent activity against 4-month-old immature as well as adult dirofilaria immitis. ten random-source dogs with naturally acquired heartworm infections (microfilariae- and antigen-positive) were given melarsomine (2.2 mg kg-1 twice 3 h apart) by i.m. inje ...19947879380
clinical prophylactic activity of melarsomine dihydrochloride (rm 340) against dirofilaria immitis in heartworm-naive beagles exposed to natural infection in three southeastern states.melarsomine dihydrochloride (rm 340), a drug being developed as an adulticide for treatment of heartworm (dirofilaria immitis) infection in dogs, was safe and highly effective as a clinical prophylactic agent against naturally acquired infections using strategic and tactical treatment programs. the strategic program involved treatment every 4 months (three series of treatments per year), disregarding the mosquito season (ms), to clear the existing infection at each treatment. the tactical progra ...19947879379
occurrence of (dirofilaria immitis) in gray fox (urocyon cinereoargenteus) in alabama and georgia.the occurrence of dirofilaria immitis in gray fox (urocyon cineroargenteus) was determined by gross examination, blood samples, and filtered tissue sediments in a sampling of 149 gray foxes taken from alabama and georgia during the 1977-78 trapping season. microfilariae were not found in blood samples obtained from 24 of these gray foxes. three of 82 male foxes (3.7%) and 1 of 67 female foxes (1.5%) were infected with heartworm. d. immitis rate of infection was 1 of 19 (5.3%) and 3 of 130 (2.3%) ...19807431520

detection of dirofilaria immitis (nematoda: filarioidea) by polymerase chain reaction in aedes albopictus, anopheles punctipennis, and anopheles crucians (diptera: culicidae) from georgia, usa.potential mosquito vectors of dirofilaria immitis (leidy) (nematoda: filarioidea), the causative agent of dog heartworm in the southeastern region of the united states, were collected with cdc light traps and gravid traps in seven counties in the state of georgia, usa. the presence of d. immitis in these mosquitoes was detected by polymerase chain reaction using species-specific primers for the d. immitis surface or cuticular antigen. overall, 1,574 mosquitoes of 13 species in seven genera were ...201020695279
diseases, parasites and survival of coyotes in south-central georgia.serologic testing, radio-telemetry and post-mortem diagnostic evaluations were used to investigate survival and causes of mortality among 17 coyotes (canis latrans) in south-central georgia (usa). prevalence of canine heartworm (dirofilaria immitis) microfilariae was lower (p = 0.057) among fall-captured (22%) than among winter-captured (75%) coyotes. prevalence of heartworm was higher among adults than juveniles in the fall, but no significant difference was detected between animals captured in ...19921474655
