This study also represented an endeavour to establish relationship between salmonellosis, mycoplasmosis and egg drop syndrome-76 infections and diverse types of reproductive abnormalities. A total of 300 Desi laying hens were randomly selected from the various poultry sale centres of Lahore and villages around Lahore. Blood sample and female genital tract of each bird were collected. The ovaries and oviducts of all hens were thoroughly examined to detect any gross pathological lesion. Organs exhibiting gross pathological lesions were subjected to histopathological examination. The biometrical study of ovaries and oviducts of all birds was also conducted. Serologically the incidence of salmonellosis, mycoplasmosis and egg drop syndrome 76 was detected by adopting rapid method agglutination test, rapid slide agglutination test and haemagglutination inhibition test, respectively.
In this study 32 (10.67%) birds exhibited five pathological conditions i.e. oophoritis, degenerated ovarian follicles, salpingitis, cystic oviduct and adenoma. Macro and microscopic pathological lesions were studied in all the above five conditions. Out of 300 serum samples, 113 (37.66%) were positive for Salmonella pullorum and Salmonella gallinarum infection, 209 (69.66%) were positive for Mycoplasma gallisepticum infection and 41 (13.66%) samples were positive for EDS-76 infection.
