First Report on the Isolation of Nocardia Thailandica from the Bronchoalveolar Lavage sample of a Patient in Iran

First Report of the Isolation of Nocardia thailandica from the Bronchoalveolar Lavage of a Patient in Iran

Nocardiae are Gram-positive, filamentous, aerobic, relatively slow-growing, and weakly acid-fast bacteria which cause nocardiosis in humans. We describe a 53-year-old patient with chronic bronchitis referred to Al-Zahra Hospital, Isfahan. A bronchial washing sample was taken from the patient. A Nocardia-like microorganism was detected in microscopic evaluation. Based on the phenotypic and 16S r...

These groups of bacteria are able to enter the human body through traumatic inhalation and may consequently cause Nocardiosis infections. Case Presentation: A 32-year-old man was referred to Al-Zahra Hospital with symptoms such as fever, gradual weight loss, and persistent coughing. First, th...

First Time Isolation of Mycobacterium hassiacum From a Respiratory Sample

We describe the first isolation of Mycobacterium hassiacum, a rapid-growing, partial acid-resistant mycobacterium, in a respiratory specimen from a patient with exacerbated chronic obstructive pulmonary disease. To provide therapeutic recommendation for future cases, antibiotic susceptibility testing of 3 clinical isolates was performed by broth microdilution. All strains tested showed suscepti...

First case of isolation of Nocardia wallacei reported in Mexico

Nocardia species are aerobic, Gram-positive bacteria with branched filaments reported as opportunistic microorganisms associated with infectious diseases of the skin. We report the isolation of N. wallacei in Mexico from a 43-year-old man, an HIV-positive construction worker who sought care for difficulty breathing and abundant sputum.
