Heartworm transmission has not been documented in Alaska and even with the importation of microfilaremic dogs, it is doubtful the climate this far north will permit maturation of infective larvae. Relocation of infected, microfilaremic dogs appears to be the most important factor contribut...

Dirofilaria immitis is a filarial nematode parasite that is currently widely enzootic in dog and coyote (Canis latrans) populations of California. Weak historical evidence suggests that the initial focus of D. immitis in California occurred 3 decades ago in the Sierra Nevada foothills (SNF) and spread to other parts of California thereafter. However, this hypothesis is difficult to evaluate bec...

Dirofilaria immitis is a filariid worm which typically lives as adult in the right ventricle of the heart and the pulmonary arteries of the dog, causing the canine heartworm disease. Therapy of canine dirofilariosis due to Dirofilaria immitis is indicated for dogs suffering from clinical signs of the disease (such as chronic cough). The present paper describes diagnostic and treatment features ...

background: the north eastern region in india is endemic for canine heartworm disease but in clinics accurate diagnosis is some times difficult. the aim of the present study was to determine the prevalence of occult infections for heartworm disease in canine in two geographical regions of north eastern india. methods : a total of 782 numbers of three categories of dogs namely, working dogs of m...

the aim of the study was to describe the urinary electrophoretic pattern of dogs with heartworm disease.urine samples from 15 heartworm-infected and 15 healthy dogs were taken. urinary specific gravity, urinaryprotein concentration and the urine protein/creatinine (u p/c) ratio were determined. urine proteins werefractionated using sds-page. results showed statistically significant differences ...

A 63 year old patient presented with a pleural effusion and a solitary lung lesion on the computed tomogram. He was found to have an inflammatory granuloma due to Dirofilaria immitis at thoracotomy.

heartworm infection is one of the most important parasitic diseases in dogs and an increasing number of cases are reported each year by necropsy in ahvaz. this study was conducted to determine the prevalence of dirofilaria immitisinfection and to investigate the risk factors related to heartworm disease in urban dogs in this area. blood samples were collected from 100 dogs from feb 2007 to feb ...

We determined the prevalence of Dirofilaria immitis (Nematoda, Filariidae) among 433 red foxes (Vulpes vulpes) in northeastern Spain, between 1990 and 1992. Forty-six (11%) of 433 foxes were infected; the intensity ranged from 1 to 36 (mean +/- SE; 4.39 +/- 0.92) nematodes per host. The prevalence of D. immitis was higher in foxes inhabiting riparian zones of the study area. This population has...

A trial of antigen prepared from Ascaris lumbricoides in the complement-fixation test for pulmonary tropical eosinophilia and for filariasis is described. No significant difference was observed between this antigen and that prepared from Dirofilaria immitis.

Acute liver failure was diagnosed in a 12-year-old cat. Fine needle aspirate cytology revealed high numbers of unsheathed microfilariae and a hepatocellular reaction with no evidence of bacterial infection. The microfilariae were identified as those of Dirofilaria repens by acid phosphatase staining. The high number of microfilariae seen in both the blood and the liver aspirate samples as well ...
