Minimum lethal concentrations (MLC) and minimum inhibitory concentrations (MIC) were determined in vitro for 8 antibiotics against 9 isolates of Mycoplasma synoviae. Of the antibiotics tested, tylosin had the highest activity, followed closely by chlortetracycline, lincomycin, oxytetracycline, spectinomycin, and tetracycline. Neomycin and erythromycin were less effective. Two antibiotic combina...

BACKGROUND The role of wild birds in the transmission and spread of mycoplasmas is not clear. Up to now different Mycoplasma species have been isolated from wild birds many of which are not considered pathogens sensu stricto for domestic flocks. This report describes the first isolation of Mycoplasma synoviae in a captive lesser flamingo (Phoeniconaias minor) held in a zoo in Italy and the labo...

Inoculation with hemagglutination-positive (HA+) cultures of Mycoplasma synoviae AAY-4 induced acute synovitis significantly more frequently (P = 0.001) in chicken tibiotarsal-tarsometatarsal joints than did inoculation with HA-negative (HA-) cultures derived from the same clone of AAY-4. Immunoblotting analyses showed that HA+ cultures abundantly expressed two phase-variable hemadherence-assoc...

The synergistic role of infectious bronchitis virus (IBV) and mixed infections of Mycoplasma synoviae (MS) and Escherichia coli (EC) in the airsacculitis syndrome was evaluated in gnotobiotic chickens. Relative air sac lesion score indexes, in descending order of severity, from various combinations of organisms were: 9.5-IBV, MS, EC; 6.8-IBV, EC; 4.5-IBV, MS; 2.7-IBV; and 0.5-MS, EC. Infectious...

On June 2005, a respiratory disease was observed in the chickens of a large broiler farm in Kermanshahprovince, west of Iran. Relatively severe respiratory signs started with sneezing at 27 days of age. Thedisease lasted up to the end of fattening period and accompanied by increased mortality (13.6%). At postmortemexamination, tracheitis, airsacculitis and pneumonia were obvious. Serologic exam...
