mycoplasma is an important respiratory tract pathogen worldwide, causing respiratory tract infection in small ruminants ( sheep and goats). it is a bacterium that causes acute respiratory illness ranging in severity from mild respiratory illness to severe pneumonia. mycoplasmosis in small ruminants is a serious and major problem in iran. this study was determined to isolate mycoplasma species a...

Mycoplasma alkalescens is an arginine-metabolizing mycoplasma, which has been found in association with mastitis and arthritis in cattle. Routine bacteriological examination of 17 bronchoalveolar lavage samples from calves with pneumonia in a single herd in Denmark, identified M. alkalescens in eight samples. The organism was found as a sole bacterilogical findings in five of the samples as wel...

Mycoplasma infection is a leading cause of pneumonia worldwide and can lead to other respiratory complications. A component of mycoplasma respiratory diseases is immunopathologic, suggesting that lymphocyte activation is a key event in the progression of these chronic inflammatory diseases. The present study delineates the changes in T cell populations and their activation after mycoplasma infe...

A nested PCR specific for the Mycoplasma pneumoniae P1 gene was used to diagnose mycoplasma infection in two cohort patients with severe pneumonia within 24 h of tissue receipt. A postmortem diagnosis of M. pneumoniae infection was obtained for the first patient, who died without the collection of appropriate paired samples for serodiagnosis. An open-lung biopsy obtained from the second patient...

Mycoplasma pneumoniae is a common causative agent for childhood pneumonia. However, empyema is a rare presentation. We report a case of a previously well child who presented with a right-sided empyema. M. pneumoniae was confirmed serologically with evidence of a four-fold rise in Mycoplasma IgM titre. The empyema required drainage procedures for more than two weeks. The infection resolved with ...

From July 1999 to November 2001, Mycoplasma sp. was cultured from lesions in 16 California sea lions (Zalophus californianus) undergoing rehabilitation. The Mycoplasma sp. was the likely cause of death of four animals in which it was associated with either pneumonia or polyarthritis. The most common lesion associated with this bacterium was subdermal abscessation, found in 12 animals. Other les...

In this study, we examined a colony of 20 beagle dogs in a laboratory animal facility. Mycoplasma was detected by consensus PCR assay in 1 dog with respiratory and constitutional symptoms. None of the other dogs were affected. The dog was euthanized and necropsied. In postmortem examinations, gray or plum-colored gross lesions were found on the lung, most commonly in the apical and cardiac lobe...

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...

Pneumonia is an important cause of morbidity and mortality among children throughout the world. Vaccines are available for some organisms, but they are underutilized and/or still in development. To evaluate the potential impact of vaccines, we review studies in which the etiology of childhood community-acquired pneumonia was recorded. In North America and Europe (9 studies), the etiology of pne...

We reported a 9-year-old boy with mycoplasma pneumonia who developed pulmonary infarction. The child first had fever and cough, and then had difficult breathing. But, the signs of his lung were not obvious. Mycoplasma antibody IgM was positive. The child was given intravenous azithromycin for anti-infection, and intravenous low molecular weight heparin and oral warfarin for anti-coagulation. Al...
