tropical theileriosis is a tick-transmitted disease which caused by obligative intracellular protozoan theileria annulata. diagnosis is usually based on identification of parasite in giemsa stained smears of peripheral blood, spleen or lymph nodes. today, the molecular methods with high sensitivity and specificity are used for diagnosis of infected and carrier animals, epidemiological and phylo...

Introduction: Mycoplasmas are one of the most serious contaminants of cellular cultures and their biological productions. Mycoplasma diagnosis is conducted on the basis of culture and molecular methods. These methods are different from each other in terms of accuracy, reliability, and sensitivity. This study aimed to trace the mycoplasma contaminations in culture samples using 16S rRNA specific...

More than 185 species, strains and unclassified Theileria parasites are categorized in the Entrez Taxonomy. The accurate diagnosis and proper identification of the causative agents are important for understanding the epidemiology, prevention and appropriate treatment. This study aims to discuss the importance of two genes of Theileria annulata 18S ribosomal RNA (18S rRNA) and Theileria annulata...

Background and Aims: Many bacteria including Escherichia coli may enter into a viable but non-culturable (VBNC) state under unfavorable stresses, which are unable to be detected by culture-based methods. In this study, the use of Reverse Transcription PCR (RT-PCR) for detection of VBNC state of E. coli O157:H7 was investigated. Materials and Methods:  Escherichia. coli O157:H7 was inoculated i...

In this study, to increase information about the relationship between caprine and ovine isolates of Pasteurella multocida, 16S rRNA gene sequencing of 9 goats (5) and sheep (4) isolates were investigated. Also, capsular type and toxAgene presentation was studied in this paper. All isolates, except one, belong to capsular type A, and toxA+ strain distributed among strains were isolated from both...
