112 specimens of capoeta capoeta gracilis from the shrioud river were examined. the prevalence and abundance of parasites were significantly higher in the area between the mouth to behind the opercle. susceptibility of infection was not significantly different between male and female fish. the prevalence of infection was the lowest in the largest length group. histopathological study revealed b...

background: intestinal parasitic infection is one of the major public health problems in developing countries. children are more vulnerable to these infections. in addition, the prevalence of infection is different among various communities; hence, there is a need for the periodical prevalence evaluation. this study was performed to define the prevalence of intestinal parasitic infection among ...

This study is focused on the investigation of honey bee samples for presence two most common and widely distributed parasites. In a two-year period during 2020-2021, 185 were tested. All examined by morphological light microscopic methods. The obtained results showed that 32.43% infested with Varroa destructor. degree infection in bees ranged from 0.5% to 60%. Spores Nosema spp. established 25....

This paper presents the results of a parasitological study on internal parasitic infections in saposhnikovi shad, Alosa saposchnikowii, from the southern part of the Caspian Sea. In this regard 30 fish were studied for abdominal cavity parasites in February 2014. Results showed all of the specimens were infected at least with one kind of parasite and there was no significant difference in paras...

  The aim of the present study was to report Philometra rischta from Blicca bjoerkna from the Caspian Sea. During this study, from August (2008) to April (2009), 78 fish specimens were collected and transferred to the aquatic research laboratory of Shahid Beheshti University and were examined for parasitic infection. Parasites were fixed in formalin (10%). The parasites were indentified accordi...

OBJECTIVE In this case-control epidemiological study, we aimed to investigate the effects of intestinal parasites on the anemia of children and show the association between intestinal parasites and anemia. METHODS A total of 50 healthy and 50 malnourished children aged 0-72 months who went to physicians of Tilfindir Primary Health Care Center were enrolled in this study. The stool specimens w...

Risk of infection by parasites can be driven by environmental heterogeneity, often at small scales. We quantified the effect of tidal elevation on infection patterns of two lethal parasites, Perkinsus marinus and Haplosporidium nelsoni, in an important coastal species, the eastern oyster, Crassostrea virginica. Within the southeastern US, oysters in Georgia and South Carolina are rarely found i...

Toxoplasma gondii infection results in co-option and subversion of host cellular signaling pathways. This process involves discharge of T. gondii effector molecules from parasite secretory organelles such as rhoptries and dense granules. We report that the T. gondii polymorphic dense granule protein GRA6 regulates activation of the host transcription factor nuclear factor of activated T cells 4...
