Advances in molecular phylogenetics have enabled reconstruction of the most likely chronology of events in prokaryotic evolution and correlation with the paleontologic record with increasing precision. Mycoplasmas probably evolved from clostridial ancestors by genome reduction leading to obligate parasitism of host cells. The vertebrate hosts present at the time of the origin of mycoplasmas abo...

The disease is caused by a mycoplasma known as Mycoplasma gallisepticum (MG).The strains of MG may differ markedly in virulence, that is, in the degree of their disease-producing power. Some strains of MG are mild while others are highly virulent (very harmful). Mycoplasma is similar to bacteria, but lacks a cell wall. Lack of wall makes MG extremely fragile. They are easily killed by disinfect...

A rapid whole cell protein antigen (iron restricted Mycoplasma gallisepticum) based latex agglutination test (LAT) was developed to detect the presence of antiMycoplasma gallisepticum antibodies in the sera of poultry affected with mycoplasmosis. The test was found to be sensitive, specific and accurate in comparison with Haemagglutination Inhibition (HI) test. The rapidity, simplicity and econ...

Twenty-four ill or dead desert tortoises (Gopherus agassizii) were received between March 1992 and July 1995 for necropsies from the Mojave and Colorado deserts of California (USA). Diseases observed in these animals included cutaneous dyskeratosis (n = 7); shell necrosis (n = 2); respiratory diseases (n = 7); urolithiasis (n = 3); and trauma (n = 5). In tortoises with cutaneous dyskeratosis th...

A cross sectional study was done to understand the effect of genotypes, farm management and agro-climatic conditions in Kerala and Uttar Pradesh on seroprevalence of Mycoplasma mycoides Subsp. capri (Mmc) in goats. Goat serum was screened by Slide Agglutination test (SAT) for Mmc antibodies. It was found that there was no statistically significant difference (P>0.05) in mycoplasma seroprevalenc...

Crocodiles and ostriches are very sensitive to stress, and the ideal conditions for intensive rearing have not yet been established. Consequently, mortality is often directly linked to conditions on the farm. Crocodile and caiman pox, adenoviral hepatitis, mycoplasmosis, chlamydiosis and coccidiosis are crocodile-specific infections with reservoirs in wild populations and adult wild-caught bree...
