background: bovine theileriosis results from infection with obligate intracellular protozoa of the genus theileria . the phylogenetic relationships between two isolates of theileria annulata , and 36 theile­ria spp . , as well as 6 outgroup including babesia spp . and coccidian protozoa were analyzed using the 18s rrna gene sequence. methods: the target dna segment was amplified by pcr. the pcr...

background and objectives: anaplasma phagocytophilum is a zoonotic, tick borne rickettsial pathogen. a. phagocytophilum has been detected in north america, europe, africa and asia by molecular methods. in iran we have little information about the distribution of this agent in human and animals. materials and methods: from march 2007 to july 2007, one hundred and fifty blood samples and correspo...

background: a. bovis and a. phagocytophilium are leukocytotropic agents of bovine anaplasmosis. they are obligate intracellular bacteria that can infect and cause anaplasmosis in human and animals. therefore, this study was carried out to detect a. bovis and a. phagocytophilum in naturally infected dairy cattle in isfahan using molecular techniques. materials and methods: in this study a total ...

background: the present study was carried out to investigate the accurate status of ovine theileria infection in sheep from ahvaz and surrounding region, a tropical area southwest iran. methods: a pcr-rflp method based on 18s ribosomal rna gene was designed which could detect and differentiate theileria and babesia spp. and also differentiate main theileria species in sheep at the same time. 11...

anaplasma bovis is a leukocytotropic agent of bovine anaplasmosis and there is no available information about molecular study on this agent in cattle of iran. in this study a total 150 cattle blood samples were collected from central part of iran. the presence of a. bovis examined using light microscopic detection and species-specific nested polymerase chain reaction (nested-pcr) based on 16s r...

objective(s) rapid tests for detection of streptococcus agalactiae or group b streptococci (gbs) at the onset of labor are needed to permit early intrapartum antibiotic prophylaxis. this study aimed to evaluate the pcr assays targeting the 16s ribosomal rna gene (16s rdna) for detection of the gbs in comparison with a specific culture method. materials and methods two swabs were used to obtain ...

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...

the protozoan intestinal parasite cryptosporidium commonly infects cattle throughout the world and iran. the present study was undertaken to determine the abundance and associated risk factors of cryptosporidium infection in cattle herds of northwestern iran. a total number of 246 fecal samples from 138 (56.1%) diarrheic (d) and 108 (43.9%) non-diarrheic (nd) cattle were randomly collected and ...
