Isolation and Molecular Identification of Mycoplasma spp. From Pigeons in the North-East of Iran
Background: Mycoplasma is one of the most important pathogens of respiratory system in poultry. OBJECTIVES: The aim of the present study was to identify Mycoplasma spp. isolated from pigeons. METHODS: Sixteen pooled samples were provided and cultured on PPLO medium and finally the DNA was extracted from the resulting single colonies. RESULTS: Through 16S rRNA gene amplification Mycoplasma genus...
متن کاملMolecular diagnosis of Mycoplasma spp. Arthritis by PCR
Background: Arthritis is one of the most common inflammatory diseases worldwide. It is characterized by symptoms such as systemic inflammation and autoantibody production. The molecular mechanisms in pathogenesis of arthritis are not fully understood. Studies show that many microorganisms, including Mycoplasmas, play a role in arthritis. The PCR method is a fast and accurate molecular method fo...
متن کاملMycoplasma mastitis.
Recognition of Mycoplasma-induced mastitis is on the increase. Although Mycoplasma bovis is identified as the causative agent in more than 50 per cent of the mastitis cases, seven other Mycoplasma species have also been isolated. The mycoplasmas are commonly found in the microflora of the respiratory and urogenital tracts of normal cattle, where precipitating factors can initiate their role as ...
متن کاملCharacteristics of staphylococci isolated from clinical and subclinical mastitis cows in Shahrekord, Iran
Staphylococci isolated from 98 mastitic cow’s milk samples were analyzed for the production of alpha,beta and delta-hemolysin on sheep, bovine and horse red blood cells and in vitro susceptibility to several antimicrobial agents. Out of a total of 18 isolated strains, 100% demonstrated hemolytic activity either alone or in combined forms. Among 8 isolates of S. aureus 3 isolates produced α/β an...
متن کاملBovine subclinical mastitis caused by different types of coagulase-negative staphylococci.
Subclinical mastitis caused by intramammary infections (IMI) with coagulase-negative staphylococci (CNS) is common in dairy cows and may cause herd problems. Control of CNS mastitis is complicated by the fact that CNS contain a large number of different species. The aim of the study was to investigate the epidemiology of different CNS species in dairy herds with problems caused by subclinical C...
