Background: Protozoa are unicellular eukaryotes. A type of intestinal protozoan pathogens is the cause of infection and serious injuries in human with or without clinical symptoms. It seems that parasitic infections as a stressor factor can affect on stress system activity and immune system function and sensitivity. The major purpose of this paper was to evaluate serum cortisol level and the ge...
First described in 1843, Rumen protozoa with their striking appearance were assumed to be important for the welfare of their host. However, despite contributing up to 50% of the bio-mass in the rumen, the role of protozoa in rumen microbial ecosystem remains unclear. Phylogenetic analysis of 18S rDNA libraries generated from the rumen of cattle, sheep, and goats has revealed an unexpected diver...
The phylum Apicomplexa includes serious pathogens of humans and animals. Understanding the distribution and population structure of these protozoan parasites is of fundamental importance to explain disease epidemiology and develop sustainable controls. Predicting the likely efficacy and longevity of subunit vaccines in field populations relies on knowledge of relevant preexisting antigenic dive...
Background: Intestinal parasites, especially coccidian parasites, cause gastrointestinal symptoms such as severe diarrhoea which increases morbidity and mortality rates in people living with Human Immunodeficiency Virus/Acquired Immunodeficiency Syndrome (HIV/AIDS), particularly in Sub-Saharan Africa. We examined the prevalence of intestinal parasites in people living with AIDS at different CD4...
The haemolymph parameters for Octopus vulgaris and the condition index at molecular level were analysed using RNA/DNA and RNA/protein ratios on animals reared in floating cage systems and naturally infected by the coccidian Aggregata octopiana. Statistical analysis showed that as A. octopiana infection increased, there was a decrease in most inorganic elements and/or in haemocyte concentrations...
Faecal samples collected from 300 Bolivian marsupials (Didelphimorphia: Didelphidae) between 1984 and 1993 were examined for coccidian parasites. Sporulated oocysts were present in the faeces of 50 (17%) marsupials representing 11 genera and 22 species. Three new species of Eimeria are described and named from six host species. One species occurred in Marmosops dorothea, Monodelphis domestica a...
background: intestinal parasites are still a serious public health problem in the world, especially in developing countries. this study aimed to assess the prevalence of intestinal protozoa infections and associated risk factors among schoolchildren in sanandaj city, iran. methods: this cross-sectional study involving 400 schoolchildren was carried out in 2015. each student was selected using s...
