introduction: the protozoan parasite, cryptosporidium spp., widely spreads in both raw and drinking waters. it is the causative agents of waterborne diarrhea and gastroenteritis in the world. in the present study, a molecular assay was used for the detection and quantification of cryptosporidium oocysts in environmental water samples. materials and methods: thirty surface water samples were col...

this study was performed from february to april 2006; several visits were made to abattoirs in the north of iran for hypoderma spp infestation. necropsy inspection of slaughtered and skinned animals were carried out by examination of the inner skin surface and subcutaneous tissues. warbles were isolated by squeezing nodules from subcutaneous tissues. in the case of abscess presence, aseptic sam...

six strain of trichoderma (t. viride, t. harzianum, t. reesei, t. longibrachiatum, t. koningii, t. virens) were isolated and used for extracellular enzyme production. species of trichoderma are collected from the surrounding soil of suger beet root fields in east iran, and held in vitro cultured pda. tcm and tfm are used for the growth of spores and induceing the production of cellulase. finall...

vibrio species are the major seafood-borne bacteria that are frequently associated with the consumption of contaminated sea food. a total of 113 samples including 58 fish and 55 shrimps were studied for the possible contamination with vibrio species. a biochemical protocol was applied for the identification of the vibrio isolates and polymerase chain reaction (pcr) was carried out to confirm th...

The phlebotomine sand fly fauna of the State of Minas Gerais is presented based on an extensive review of the literature. The fauna, which is a rich one, is currently known to consist of at least 93 species included in 16 genera. The genus Evandromyia (16 spp.) is the most representative one, followed by Micropygomyia (13 spp.), Psathyromyia (12 spp.), Brumptomyia (11 spp.), Pintomyia (9 spp.),...

Parasites are a well-known threat to nonhuman primate (NHP) populations, and potentially cause zoonotic diseases in humans. In this study, the basic data was provided of the parasites in NHPs and the molecular characterization of the Enterocytozoon bieneusi, Giardia duodenalis, Cryptosporidium spp., and Entamoeba spp. were reviewed, which were found in these samples. A total of 3349 fecal sampl...
