although the biology and ecology of the arthropod vectors are different, some factors, such as global warming, the increasing abundance of mosquitoes, the movement of domestic hosts, and the abundance of wild reservoirs, can act as favourable factors for the distribution of infections. the aim of this study was to determine the prevalence of dirofilaria immitis infection in shepherd dogs living...

An asymptomatic patient with a pulmonary coin lesion surgically diagnosed with pulmonary dirofilariasis caused by infection with Dirofilaria immitis (D. immitis) is presented. The preoperative stored serum of the patient was positive for D. immitis by enzyme-linked immunosorbent assay (ELISA). A family study showed that three of five family members were seropositive for D. immitis. These result...
The canine heartworm, Dirofilaria immitis, is among the most important parasites of dogs in United States and worldwide, may cause severe potentially fatal disease. Current diagnostic recommendations rely on serological detection an adult female antigen, visualization microfilariae blood. Therefore, a reliable diagnosis can be only performed approximately six months post-infection. There growin...
An immunological procedure for the rapid and specific identification of Coccidioides immitis isolates has been developed. The specificity of the procedure is based on the fact that C. immitis produces antigens that are not produced by morphologically similar fungi. The procedure involved the transfer of heavy mold-form inocula to flasks that contained small volumes of brain heart infusion broth...
The AccuProbe Coccidioides immitis culture identification test (CI test) yielded false-negative results with formaldehyde-killed C. immitis submitted to a reference laboratory. Further evaluation with pure or mixed cultures or stored, heat-killed cultures revealed the CI test to be highly sensitive and specific for C. immitis except when the cultures were pretreated with formaldehyde.
BACKGROUND Dirofilaria immitis, a filarial nematode, is the most important parasite-affecting dogs, causing cardiopulmonary dirofilariasis. Current diagnostic tools for detecting D. immitis include morphological assays, antigen detection, and X-ray. Herein, we developed a method for the molecular detection of D. immitis in blood using polymerase chain reaction (PCR). METHODS The study was con...
This study was performed to investigate whethere there is cross-reactivity between Dirofilaria immitis and three intestinal nematodes of dogs. In ELISA, D. immitis-infected dog sera obtained at the 4th molting stage (9-11 weeks) and microfilaremic stage (25-30 weeks) were shown to be highly reactive with crude extract of T. canis. In immunoblotting, some antigenic fractions, 44, 57, 88, 100 kDa...
Introduction Coccidioidomycosis, commonly referred to as Valley Fever, is caused by the soil-borne saprophytic fungus C. immitis and posadasii. These species have historically been found in the desert southwest and Mexico; however, in 2010 there were three coccidioidomycosis cases identified in central Washington. Colonization of soils by C. immitis has been confirmed at exposure sites associat...
