Numerous methods are currently used throughout the poultry industry for the administration of vaccines. Each utilizes water for vaccine reconstitution and/or administration, including two of the three commercially available live Mycoplasma gallisepticum (MG) vaccines. Selected water temperatures were used to reconstitute and/or dilute the three commercially available live MG vaccines. Water tem...

Mycoplasma gallisepticum, the most pathogenic mycoplasma in poultry, is able to glide over solid surfaces. Although this gliding motility was first observed in 1968, no specific protein has yet been shown to be involved in gliding. We examined M. gallisepticum strains and clonal variants for motility and found that the cytadherence proteins GapA and CrmA were required for gliding. Loss of GapA ...

Mycoplasma gallisepticum is an etiologic agent of chronic respiratory disease in chickens and infectious sinusitis in turkeys. Other than proteins important for cytadherence, few M. gallisepticum factors or pathways contributing to host cell interactions have been identified. In this study, an oligonucleotide-based microarray was utilized to investigate transcriptional changes in M. galliseptic...

Mycoplasma gallisepticum belongs to class Mollicutes and causes chronic respiratory disease in birds. It has a reduced genome, lack of cell wall and many metabolic pathways, and also easy to culture and non-pathogenic to humans. Aforementioned made it is a convenient model for studying of systems biology of minimal cell. Studying the transcriptomic level of M. gallisepticum is interesting for b...

This study was conducted to determine the effect of overlaying (revaccinating) F-strain Mycoplasma gallisepticum at 22 or 45 wk of age on commercial leghorn hens previously vaccinated with 6/85-strain M. gallisepticum at 10 wk of age. The treatment groups included unvaccinated hens (group 1), hens receiving 6/85-strain M. gallisepticum only (group 2), and hens receiving 6/85-strain M. gallisept...

The data reported is a large-scale untargeted proteome profile for Mycoplasma gallisepticum - a model organism for studying both regulation in genome-reduced bacteria and intracellular infection (Mazin et al., 2014) [1,2]. While seminal whole-proteome studies were performed on Mycoplasma genitalium [3] and a few proteome datasets are available for Mycoplasma pneumoniae, no data-independent (DIA...

Gill, James W. (University of New Hampshire, Durham). Culture and metabolism of Mycoplasma gallisepticum. J. Bacteriol. 83:213-218. 1962.-Mycoplasma gallisepticum A5969, a strong-growing pleuropneumonia-like organism pathogenic for poultry, was found to be intolerant of extremes of temperature and potassium ion concentration. It ferments glucose to the benefit of cell yield, but glycolysis appe...

A new mycoplasmal conjunctivitis was first reported in wild house finches (Carpodacus mexicanus) in early 1994. The causative agent was identified as Mycoplasma gallisepticum (MG), a nonzoonotic pathogen of poultry that had not been associated with disease in wild songbirds. Since the initial observations of affected house finches in the mid-Atlantic region, the disease has become widespread an...

Mycoplasma gallisepticum and Mycoplasma synoviae are the causative agents of avian mycoplasmosis in commercial poultry. Among the available tools, polymerase chain reaction (PCR) and culture are confirmatory tools for the diagnosis of mycoplasmosis after the initial serological screening of suspected birds. Overall, 181 samples were analyzed, 152 (84%) and 103 (57%) of which were found positive...
