Sir, Nocardiosis is an uncommon but world-wide infection caused by several species of soil-borne aerobic bacteria belonging to the genus Nocardia (1). Nocardiosis can be divided into two broad categories: disseminated and cutaneous. Disseminated nocardiosis, which accounts for most occurrences of nocardiosis, is most commonly caused by N. asteroides, and typically affects immunocompromised host...

J. Bacteriol. 90:571-574. 1965.-The group-specific polysaccharide of Nocardia brasiliensis was further purified, yielding an amorphous white material with the following characteristics: [alpha](D) (2...

Nocardia pseudobrasiliensis is predominantly associated with invasive infections in immunocompromised patients. We report a case of disseminated mycetoma caused by N. pseudobrasiliensis in a 57-yr-old woman with microscopic polyangiitis, who was treated for 3 months with corticosteroids. The same organism was isolated from mycetoma cultures on the patient's scalp, right arm, and right leg. The ...

The lack of simple and efficient methods for extraction of DNA from Nocardia spp. has hampered molecular manipulation of the DNA for diagnostic purposes. In the present study, a method for the rapid extraction of undegraded genomic nocardial DNA was established. Briefly, 14 pathogenic Nocardia strains were grown at 37 degrees C for 3 to 5 days in Sauton broth containing 0.05% Tween 80. Subseque...

BACKGROUND Pulmonary nocardiosis mimic pulmonary tuberculosis in most clinical and radiological manifestations. In Tanzania, where tuberculosis is one of the major public health threat clinical impact of nocardiosis as the cause of the human disease remains unknown. The objective of the present study was to isolate and identify Nocardia isolates recovered from TB suspects in Northeastern, Tanza...

Nocardiosis is an uncommon but serious infectious disease caused by gram-positive branching filamentous bacilli. It belongs to the Actinomycetales order and is a weak acid-alcohol-fast bacterium. It inhabits the telluric environment where they contribute to the degradation of organic matter and its transmission generally occurs through inhalation or direct inoculation of spores [1,2]. Seven spe...
