[ 1 ] - Nucleotide sequence analysis of the Second Internal Transcribed Spacer (ITS2) in Hyalomma anatolicum anatolicum in Iran

Ticks are important acarina that infest animals. They are obligatory blood sucker arthropods which economically impact cattle industry by reducing weight gain and production. Moreover, they are important vectors of viral, bacterial, rickettsial and parasitic pathogens infecting humans and animals. In view of the importance of Hyalomma anatolicum anatolicum in pathogen transmission, including Th...

[ 2 ] - Serological study of Neospora caninum in pregnant dairy cattle in Tehran, Iran

Seven hundred and sixty-eight blood samples of pregnant cattle from four Holstein dairy herds that are farmed in the vicinity of Tehran were used to evaluate the seroprevalence of Neospora caninum infection by enzyme-linked immunosorbent assay (ELISA). Two hundred and ninety-eight of the 768 blood samples (38.8%) were positive for this infection. The prevalence of infection in the herds varied ...

[ 3 ] - Identification of Theileria species in sheep in the eastern half of Iran using nested PCR-RFLP and microscopic techniques

Theileria species are common in tropical and subtropical regions and cause great economical losses inruminants. Two species, T. lestoquardi and T. ovis, are suspected to cause ovine theileriosis in Iran. Theepidemiological aspects of ovine theileriosis in Iran are poorly understood and further investigations bysensitive and precise techniques are required. In a previous study, a sensitive and s...
