ABSTRACT Avian mycoplasmosis is infectious and contagious disease which affects chicken and turkey as well as many other species with many economics losses. The absence of data on avian mycoplasmosis in Algeria and the importance of the poultry breeding in Batna encouraged us to undertake the prevalence of the most pathogenic mycoplasmas in broiler and layer chickens in this area, Mycoplasma gallisepticum (MG). 143 Mycoplasmas were isolate from 237 samples, at a rate of 60.33%. MG was isolate at a rate of 21.67% (2.09% in layer hens and 19.58% in broiler chickens). The serological screening using of breedings showed a sensitivity of 83.10%. This study shows that mycoplasmosis and in particular MG infection, represent a serious problem in chickens in Algeria in the absence of hygiene conditions and vaccination especially. [Vet.

    ABSTRACT: This study aimed to determine the seroprevalence of Mycoplasma gallisepticum (MG) infection in the chicken population of Bhola district, Bangladesh, during the period from April 2011 to March 2012. A total of 480 blood samples from chickens were collected from different upazilas (sub-districts) of Bhola district. The sampling considered the types of chicken (backyard and commercial layer), age groups (pullet, adult and old) and seasons (summer and winter). On the basis of the serum plate agglutination test, 55.83% (n=268/480) chickens were found positive for MG. The MG infection was higher (62.5%) in backyard chickens as compared to those being reared in commercial farming systems (53.61%). With respect to age groups, the prevalence was highest in pullets (60.63%) followed by adults (55.63%) and old chickens (51.25%). Moreover, chickens reared in winter showed higher prevalence of MG (60.42%) as compared to those reared in summer (51.25%). In conclusion, MG infection is prevalent in the chicken population of Bhola district, Bangladesh. Appropriate strategies should be taken for successful prevention and control of this disease in Bangladesh.
