Thirty-seven house finches (Carpodacus mexicanus) with conjunctivitis were admitted to a rehabilitation center. Six (35%) of 17 conjunctival swab samples collected before treatment began were positive on culture for Mycoplasma gallisepticum. All birds were treated with cipro­ f10xacin hydrochloride ophthalmic solution (one drop in each eye [OU] q 12h) for 5 to 7 days and tylosin tartrate in wat...

We describe a method for the simultaneous identification of up to three Mycoplasma species by the use of contrast-labeled fluorescent antibodies against two species and peroxidase-labeled antibody against a third species. The procedure enabled the rapid identification of colonies of three artificially mixed avian Mycoplasma species on agar blocks and also mixtures of species in cultures from na...

Avian mycoplasmosis is an important disease of poultry of great economic importance. It is caused by four (4) pathogenic mycoplasma species namely Mycoplasma gallisepticum, Mycoplasma synoviae, Mycoplasma meleagridis and Mycoplasma iowae; although other Mycoplasma species have also been incriminated in the disease. The disease causes cough, rales, ocular and nasal discharges, decreased feed int...

Five arginine-utilizing, nonglycolytic Mycoplasma species were compared serologically by two dimensional immunoelectrophoresis. The survey included: Mycoplasma hominis, Mycoplasma arthritidis, Mycoplasma gateae, Mycoplasma gallinarum, and three strains of Mycoplasma arginini. Although the M. arginini strains showed strong cross-reactions, each strain produced a different antigenic profile which...

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...

An innovative approach for inactivation of Mycoplasma gallisepticum using the hydrophobic photoinduced alkylating probe 1, 5-iodonaphthylazide (INA) is described. Treatment of washed M. gallisepticum mid-exponential culture (0.2 mg cell protein /mL) with INA followed by irradiation with far-ultraviolet light (310-380 nm) completely abolished viability. Transmission electron microscopy showed th...

BACKGROUND The quinoxaline 1,4-di-N-oxides (QdNOs) were known as potent antibacterial agents. For the purpose of evaluating the bioactivity of existing animal-used QdNOs drugs against representative pathogenic microorganism, the representative drugs of quinoxalines including cyadox, mequindox, quinocetone and their metabolites were submitted to the in vitro evaluation for antituberculosis, anti...

The surface carbohydrate structures on the cell membranes of various mycoplasma species have been investigated by using lectins, which are sugar-specific proteins. Carbohydrate structures presumably bound to glycolipids, with both galactose and glucose units, were found to be exposed on the surface of Mycoplasma pneumoniae and its temperature-sensitive mutants, M. mycoides var. mycoides and cap...
