background: coccidiosis is an intestinal disease of chickens caused by various species of proto­zoan parasites within the genus eimeria . diagnosis and genetic characterization of different spe­cies of eimeria are central to the prevention, surveillance, and control of coccidiosis. the aim of this study was to detect different chicken eimeria species from several areas in khuzestan, south­west ...

abstract in composting process for the white button mushroom, in addition to chemical reactions of complex compounds present in straw, which provide simple compounds for the mushroom, thermophilic microorganisms, having accumulated n2 and inorganic matter during the composting processes, offer the microbial biomass as a secondary nutritional source to be consumed by the fungus agaricus bisporus...

Leishmania donovani is considered the causative organism of visceral leishmaniasis (VL) and post-kala-azar dermal leishmaniasis (PKDL). Testing of 4/29 DNA samples from VL and PKDL patients as well as 2/7 field isolates showed an aberrant internal transcribed spacer 1 (ITS1) restriction fragment length polymorphism (RFLP) pattern, which upon sequencing strongly matched Leptomonas seymouri, thus...

Abstract Specific identification of oestrid larvae is usually problematic not only when using morphobiometric features, but also applying molecular criteria, since very few markers have been described for this group flies. New are needed more reliable species identification, diagnostic purposes, and epidemiological surveys; moreover, they can help in phylogenetic reconstruction. Here, we report...

A stand of Paramecium novaurelia was found in Boston Massachusetts, USA, the first on this continent. Molecular studies (RAPD and sequencing ofrRNA [3'SSUrRNA-ITS1, 5' LSU rRNA] and COI mtDNA fragments) of P. novaurelia strains show intra-specific polymorphism within the species as strain clusters characterized by variable relationships.

We report a case of endocarditis in a human infected with Bartonella vinsonii subsp. berkhoffii, which causes bacteremia and endocarditis in dogs. Bacterial identification was established by PCR amplification and sequencing of an intergenic spacer region (ITS1), 16S ribosomal DNA, and a gene encoding citrate synthase (gltA). Bartonella antibodies were detected by immunofluorescence.
