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...

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 ...

Inbred strains of mice vary in their susceptibility to Coccidioides immitis. We infected resistant DBA/2 (D2) mice and three susceptible strains of mice (C57BL/6 [B6], BALB/c, and CAST/Ei) by intraperitoneal injection of arthroconidia and determined the severity of infection based on colony counts of fungus in the spleens and lungs 14 days after infection. We used quantitative reverse transcrip...

We report the isolation of a Coccidioides immitis gene (SOWgp) which encodes an immunodominant, spherule outer wall glycoprotein that is presented as a component of a parasitic phase-specific, membranous layer at the cell surface. The open reading frame of the gene from C. immitis isolate C735 translates a 422-amino-acid (aa) polypeptide that contains 6 copies of a 41- to 47-residue tandem repe...

Dirofilariasis is globally the commonest manifestation of zoonotic filariasis. We report the detection of a novel canine species causing human and canine dirofilariasis in Hong Kong. Three human cases occurring over 10 months were identified, one presenting with cervical lymphadenopathy, one with an abdominal subcutaneous mass, and one with a subconjunctival nodule. Transected worms recovered f...

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 ...
