Abstract
Pakistani poultry industry represents one of the largest agro based segment of economy which is growing continuously, providing numerous opportunities for the spread of multiple diseases in the absence of control measurements. Respiratory diseases are continuing to cause heavy economic losses in the poultry industry and increase the overall cost of production in terms of the provision of services of qualified veterinary personnel and the cost of medication for possible treatment. It is therefore important to reduce if not eliminate, respiratory infections among poultry flocks to the barest minimum to have good production and maximize profit of the producer. Various pathogens may initiate respiratory disease in poultry, including mycoplasmosis caused by Mycoplasma gallisepticum (MG).The present study was conducted in 25 commercial layer flocks of hyline and leghorn breed in Tehsil Chakwal, Tehsil Talagang and Tehsil Kallar Kahar, Chakwal District, Punjab Pakistan. Totals 358 blood samples were collected and subjected to serological test. The overall seroprevalence of MG was found through iELISA and SPA as 29.88 % and 20.67% respectively. Further, high prevalence of MG was recorded in 24-31 weeks old layers (44.17%) as compared to 55-63 weeks old layers (14.49%). Lack of vaccination, MG positive breeder flocks or improper biosecurity measures may be the possible reasons behind this high prevalence. The study of seasonal effect on MG infection in birds suggested that high MG prevalence in winter than summer. Moreover, our findings revealed highest MG prevalence in December (44%) while lowest in October (20%). It can be assumed that low temperature increase susceptibility of layers for MG infection. Furthermore, higher prevalence was recorded in layer flocks (33.33%) with large number of birds (4000-5000) than flocks (24.28%) with small number of birds (1000-2000). In addition, it was also found that iELISA test is more sensitive and specific for detection of MG antibodies in serum samples as compare to SPA test although mostly SPA test is being used for serological screening of flocks in field. This evidence emphasize the need of further detailed and more systemic approaches for MG distribution and prevalence investigation to design effective control strategies. A comprehensive epidemilogical surveys for the detection of MG and evolution using molecular tools will improve the understanding of the global epidemiology of the infection.
