Pneumonia due to Nocardia
cyriacigeorgica in a patient with Crohn's disease treated with infliximab.
9,10) Sulfur granules, however, are not pathognomonic for Actinomyces because other organisms such as Nocardia
, Sporotrichum, and Phialophora spp also produce them.
The genus Nocardia
includes more than 80 species, at least 33 of which cause disease in humans.
Treatment of intracranial Nocardia
abscess includes intravenous therapy with two antibiotics, such as trimethoprim/sulfamethoxazole plus amikacin.
asteroides is a species of Nocardia
that is pathogenic to humans and is typically complexed with two other pathogenic species of Nocardia
The two actinomycetes organisms were isolated and identified as Streptomyces and Nocardia
They were Streptomyces alanosinicus, Streptoverticillium album, Nocardia
farcinia, Streptomyces atratus, Nocardia
amarae and Micromonospora chalcea.
Brain abscess due to Nocardia
species is a rare condition, and although it can occur in patients with an intact immune system, it is usually seen among immunocompromised patients.
Several different organisms, such as Rhodococcus ruber, Nocardia
lucida, Coryne-bacterium hydrocarboxydans, and Haloferax mediterranei, and members of some genera of the non-purple sulfur bacteria like Rhodobacter, Rhodocyclus, Rhodopseudomonas, and Rhodospirillum, are able to accumulate P3(HB-co-x%HV) from unrelated carbon sources (3), (4).
asteroides and Neisseria gonorrhoeae are a selection of the most frequently cultured organisms.
At autopsy, Nocardia
was cultured from multiple renal abscesses.
21,22) Poly-[beta] hydroxy-butyrate (PHB) is a very common energy-storage material in many microorganisms, such as Alcaligenes, Azatobacter, Bacillus, Nocardia
, Pseudomonas, and Rhizobium.
Actinomycotic mycetomas can be caused by Nocardia
brasiliensis, Streptomyces somaliensis, Streptomyces madurae, and Streptomyces pelleteri.
Intralobar and extralobar bronchopulmonary sequestration complicated by Nocardia
tuberculosis (TB), Mycobacterium avium-intracellulare (MAI), pseudomonas, and nocardia
