Detection and Isolation of Mycoplasma capricolum Subspecies Capricolum from East Azerbaijan Sheep Flocks

Mycoplasma capricolum subspecies capricolum (Mcc) is one of the causative agents of contagious agalactia (CA), which is an important disease in sheep and goats in the Mediterranean and Middle East countries. Mycoplasma agalactiae is the classic agent of CA in sheep and goats. Mycoplasma mycoides subspecies Capri (Mmc), Mycoplasma capricolum subspecies capricolum (Mcc), and Mycoplasma putrefaciens (Mp) produce a clinically similar disease, more often in goats. The aim of the present study was to detect Mcc in sheep flocks in East Azerbaijan Province of Iran. Milk, ear canal, and eye swab samples were collected from 49 sheep flocks with clinical signs of CA or a history of a disease. All the samples were examined using both culture and molecular methods. In the molecular method,positive samples for the Mycoplasma genus were tested for M. mycoides cluster and Mcc. From 272 samples, 67, 87, and 62 samples were shown to be positive using the culture method, polymerase chain reaction (PCR) method, and both culture and PCR methods, respectively. Mcc was detected in all the four M. mycoides cluster positive samples, including milk, ear canal, and eye swab samples. This is the first report of Mcc detection from East Azerbaijan. Our results showed that eye, milk, and ear canal samples could be suitable sources for Mcc detection in sheep flocks.
