Impacts of Mycoplasma gallisepticum Vaccine on Newcastle Disease Vaccination and Protection in Parent Stock Flocks

Molecular detection and phylogenetic analysis of Mycoplasma gallisepticum from backyard and commercial turkey flocks in Iran

Mycoplasma gallisepticum (MG) is economically important pathogen of poultry causes airsacculitis and frequently infraorbital sinusitis in turkeys. Infections may remain without clinical signs, but they can make birds susceptible to secondary infections.This study was carried out for molecular detection and phylogenetic analysis of MG infections in commercial and backyard turkey flocks ...

Serologic profile of avian leukosis virus subgroup-J, Mycoplasma gallisepticum and Mycoplasma synoviae in broiler grandparent flocks of Iran.

  Avian Leukosis Virus Subgroup-J (ALV-J). Mycoplasma gallisepticum (MG) and MycopJasma synviae (MS) are important pathogens in chickens that cause severe economical losses in poultry industry throughout the world. Seven broiler grandparent flocks of Iran (six broiler strains) were sampled randomly at the ages of 8-63 wk (100 samples from each flock) for antibody detection to ALV-J, MG, and MS ...

Mycoplasma synoviae infection on Newcastle disease vaccination of chickens

Newcastle disease is characterized by respiratory manifestations in association with nervous and/or digestive symptoms. Its prevention is done by vaccination with live attenuated (lentogenic strains) and/or killed vaccines. The lentogenic strains can lead to strong post-vaccination reaction, principally due to the presence of other pathogenic agents. Among them, Mycoplasma synoviae is worldwide...

Characterization of Mycoplasma Gallisepticum Isolated from Commercial Poultry Flocks

Chronic Respiratory Disease (CRD) is caused by Mycoplasmas gallisepticum (MG) and is prevailing in layer, broiler and breeder poultry flocks. The infected birds showed sneezing, rales, coughing and exudates from nostrils and eyes. Mycoplasma species were recovered 27.3% overall, 39.3 per cent of the tracheal swabs, 15.9 per cent of tracheal tissues, 27.4 per cent of lung tissues and 25 per cent...
