ABSTRACT: The brown howler monkey (Alouatta guariba clamitans) is a primate species widely distributed in South America. Infections by protozoa are common primates. However, studies on primates Brazil scarce, so the goal of this study was to investigate DNA from apicomplexan Neospora caninum, Sarcocystis spp. and Toxoplasma gondii tissues A. clamitans. extraction performed tissue samples heart,...

sarcocyst is one of the most important protozoa belonged to apicomplexa. this parasite is prevalent among warm blooded animals throughout the world. in the present work, sarcocystis gigantea was identified by amplification of 18s rrna gene using pcr- rflp. in this regard macroscopic cysts of sarcocystis were collected from esophagus and intra costal muscles of sheep in shahriar slaughterhouse. ...

The genus Eimeria belongs to the phylum Apicomplexa, which includes many obligate intracellular protozoan parasites of man and livestock. E. tenella is one of seven species that infect the domestic chicken and cause the intestinal disease coccidiosis which is economy important for poultry industry. E. tenella is highly pathogenic and is often used as a model species for the Eimeria biology stud...

During a survey conducted in a fish farm located in NW Portugal Cryptosporidium sp. sporogonial stages were detected in bile ducts epithelial cells of turbot (Psetta maxima). Fibrosis surrounding the infected bile ducts and necrosis of adjacent hepatic cells were observed. *Corresponding author’s E-mail: [email protected] The turbot, Psetta maxima (Linnaeus, 1758) is a very important marine fis...

The diverse functional roles that proteases play in basic biological processes make them essential for virtually all organisms. Not surprisingly, proteolysis is also a critical process required for many aspects of pathogenesis. In particular, obligate intracellular parasites must precisely coordinate proteolytic events during their highly regulated life cycle inside multiple host cell environme...

The coccidia (protistan phylum Apicomplexa Levine, 1970) comprise a large group of obligate intracellular parasites commonly found in all classes of vertebrate hosts and in some invertebrates. This review focuses on those species within the Eimeriidae because they are among the most prevalent and speciose of all parasite groups, and there is no taxonomic summation currently available for those ...
