Subject(s): Online resources: In: Zagazig Veterinary Journal 2007.v.35(3)Summary: A total of 100 chicken cases of different ages showed chinical sgins of chronic respitatory disease (CRD) collected from 20 different farms from Dakahlia governorate were used in the study. Tracheal, nasal swabs., lung and air sacs samples were collected for Mycoplasma gallisepticum (MG) isolation and liver, lung, kidney. bone marrow and air sacs were collected for E coli isolation. Primary isolation and biochemical characterization lead to live Mycoplasma gallisepticum and one M.gallinarum isolates (named DS1. DS2, DS3. DAS4 (M. gallinarum), DAS5 and DT6SC) which were confirmed by PCR except DAS4. The previous isolates and one MG reference isolate were included in Minimum inhibitory concentrations (MIC) assay for seven antibiotics (Doxycycline, Spiramycin, Erythromycin, Tilmicosin. Tiamulin. Tylocin and Enrofloxacin).
