The objective of the study was to determine the frequency of nocardiosis in HIV-positive and HIV-negative individuals clinically suspected of having tuberculosis (TB). The study population (n = 171) were those who attended chest hospitals in Khartoum State, Sudan, between January and March 2010. The patients suffered from pulmonary infections with positive acid-fast bacilli. Blood (n = 171) and...

The mortality rate and histopathological features of Nocardia asteroides and Nocardia brasiliensis infections in congenitally athymic (nude) mice of ICR and C3H/eB origins were quite different from what we found for Swiss white mice and other inbred mouse strains (namely, C57/BL/6J, New Zealand Black, BALB/c, CBA/LAC, and C3H/eB). The immunocompetent littermates of the congenitally athymic mice...

Nocardiosis refers to a locally invasive or disseminated infection associated with the Nocardia species. Most infections enter through the respiratory tract and then disseminate systemically. Rarely can a primary nocardial infection of the skin spread to contiguous structures or disseminate to other internal organs in immunocompromised hosts. We describe a 70-year-old woman who suffered from re...

Systemic lupus erythematosus (SLE) is per se a disease characterized by suppressed immune response and thus susceptibility to various opportunistic infections. We describe the case of a 21-year old woman who developed a rare zoonosis - hemotrophic mycoplasma infection in the initial stage of SLE, complicated with Nocardia asteroides pneumonia afterwards. Nocardia infection coincided with initia...

introduction: nocardia is saprophytic soil bacterium of the actinomycetes families. nocardia has high diversity of species and due to species diversity of nocardia, phenotypic tests are essential for early identification of nocardia species. methods: 155 soil samples from different regions of north khorasan province in iran were collected, including: urban and rural areas. isolation of nocardia...

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 ...
