background : mosquitoes are considered as the vectors of dirofilariasis and some vector borne disease in iran. the objective of this study was to determine the susceptibility level of the vectors to various insecticides recommended by who for any control measures in an endemic area in northwestern iran. methods : mosquito larval and adult collections were carried out using different methods pro...

1. The literature concerning inhalation infection with Coccidioides immitis is briefly reviewed. 2. A laboratory technique for exposing animals to inhalation of the spores of Coccidioides immitis is described. 3. Primary pulmonary infection was produced in 42 per cent of 72 animals exposed by this method. 4. No marked weight loss was apparent in the animals infected. 5. Skin tests with coccidio...

A case of periocular dirofilariasis has been diagnosed in Iran. A 27-yr old female referred with a history of edema and redness in the left eye since 2 wk ago. On slit lamp examination, a moving thread-like worm was seen in the subconjunctival area. Two days later, a 126 mm long, live filaria worm was extracted from the lower lid subcutaneous tissue. The worm was diagnosed as, likelihood, Dirof...

Microfilarial periodicity of Dirofilaria immitis (the dog heartworm) was determined at two hr intervals for 72 consecutive hrs in 10 naturally infected war dogs, 3-9 years old, in Korea to facilitate harvest of the microfilariae for possible use in laboratory works and to elucidate further the periodicity of the microfilaria depending on geographic location. Although the periodicity had been ob...

Morphological descriptions of Dirofilaria immitis are scarce. For this reason, we carried out morphological studies using both light and scanning electron microscopy for this filaroid species. Morphometric and morphological data were compatible with previous descriptions of D. immitis , but several anatomical structures are described by scanning electron microscopy for the first time, such as d...

Coccidioidomycosis (valley fever) is caused by the dimorphic fungi Coccidioides immitis or Coccidioides posadasii. Most infections are asymptomatic or result in self-limited pneumonia; extrapulmonary dissemination via either hematogenous or lymphatic spread is rare. Here, we present a case of cervical C. immitis lymphadenitis that resulted in fistula formation to the esophagus via mediastinal e...

Peripheral blood leukocytes from guinea pigs infected with Coccidioides immitis 5 weeks previously were lysed significantly when incubated at 37 C for 3.5 hr with a concentrated C. immitis culture filtrate, but not with a concentrated Aspergillus fumigatus or Blastomyces dermatitidis culture filtrate. Mononuclear leukocytes and presumably granulocytes were both lysed. Characterization of the fa...

Documentation is offered for the identification of 3-O-methyl-mannose as one of several neutral sugars found in defatted arthrospore and mycelial cell walls of Coccidioides immitis.

Forty-nine isolates of arthroconidial fungi other than Coccidioides immitis did not produce immunodiffusion lines of identity with the reference system for that fungus.
