Mycoplasma pneumoniae infection is a common cause of community-acquired pneumonia.’ It may cause a dry cough, dyspnea, and an interstitial infiltrate on chest radiography. Hypersensitivity pneumonitis may present with similar symptoms and radiologic features.’ We recently cared for a 46-year-old ex-smoker who presented with dyspnea, a dry cough, and malaise of 3 weeks’ duration. Treatment with ...

A retrospective study of Mycoplasma otitis in California calves submitted for necropsy between 1993 and 2002 was conducted to characterize the demographic features of the disease and the pathologic findings associated with infection. Sixty-one confirmed cases of Mycoplasma otitis were identified among 20,525 necropsied cattle. All affected animals were calves, ranging in age from 2 weeks to 4 m...

After 2 days of fever, a 5-year-old boy had a partial seizure, then became encephalopathic and anarthric. MRI (figure) was consistent with bilateral striatal necrosis and Mycoplasma pneumonia immunoglobulin G and immunoglobulin M serology was positive. He was treated with plasma exchange and IV steroids with improvement in consciousness and speech. One month later he developed oromandibular, li...

Mycoplasma pneumoniae is a leading cause of community-acquired pneumonia. Although two genetically distinct types of M. pneumoniae are known, variants of each also exist. We used a real-time PCR high-resolution melt genotyping assay to identify clinical variants which may provide greater insight into the genetic distribution of M. pneumoniae strains.

Mycoplasmas cause several diseases in cattle as pneumonia in calves and mastitis in cows and also reproductive disorders, abortions, arthritis and conjunctivitis. The difficulty of culturing mycoplasmas in vitro is a major obstacle to research and laboratory diagnosis of these fastidious organisms. A total of 120 preputial swabs, 70 vaginal swabs and 65 milk samples were collected from cattle a...

AIMS To assess the sensitivity, specificity, and predictive value of procalcitonin (PCT) in differentiating bacterial and viral causes of pneumonia. METHODS A total of 72 children with community acquired pneumonia were studied. Ten had positive blood culture for Streptococcus pneumoniae and 15 had bacterial pneumonia according to sputum analysis (S pneumoniae in 15, Haemophilus influenzae b i...

Context: Community-acquired pneumonia (CAP) refers to attained outside the hospital or less than 48 hours before admission, which is a significant cause of mortality and morbidity, especially in major comorbidities older age. Several microorganisms contribute developing CAP, primarily Streptococcus pneumonia, Haemophilus influenza, Moraxella catarrhalis, atypical pathogens, e.g., Mycoplasma pne...
