Nocardia asteroides and, to a lesser extent, Nocardia brasiliensis are responsible for most cases of Nocardia pneumonia. Nocardiae are aerobic, gram-positive bacilli present mainly in soil. Approximately 50% of patients have no underlying disease . Nocardia cyriacigeorgicaGUH-2 (6.1 Mb), NocardiabrasiliensisHUJEG-1 (9.4 Mb) and Nocardia farcinicaIFM 10152 (6.29 Mb) share 1562 highly conserved CDS coding for different cellular processes (Fig. 40.10) Seven cases of infection due to Nocardia brasiliensis were identified over a 13-year period at Duke University Medical Center, Durham, North Carolina. These seven cases and a review of 55 cases in the literature reported from the United States show that N. brasiliensis can cause a wide spectrum of disease Granules are most often seen in infections caused by N. brasiliensis, but also can be produced by other Nocardia species. Gram stain Gram staining is the most sensitive method by which to visualize and recognize Nocardia in clinical samples. Clinical specimens Beaded Gram positive rods, 0.5-1.0, thin, filamentous and typically right angle. Nocardiosis is a disease caused by a type of bacteria that is found in the environment, typically in standing water, decaying plants, and soil. These bacterial species belong to the genus Nocardia giving the disease its name. Nocardia and other related bacteria are considered to be opportunistic pathogens

Nocardia brasiliensis is an important etiologic agent of mycetoma. These bacteria live as a saprobe in soil or organic material and enter the tissue via minor trauma. Mycetoma is characterized by tumefaction and the production of fistula and abscesses, with no spontaneous cure. By using mass sequencing, we determined the complete genomic nucleotide sequence of the bacteria Discussion. Nocardia is a genus of aerobic Gram-positive bacteria. Unlike other Gram-positive bacteria, Nocardia appears as branching, beaded, filamentous bacilli on Gram stain.1-6 Actinomyces can resemble Nocardia on Gram-stained sample. However, Nocardia exhibits weak acid fastness and grows only under aerobic condition.1-6 Nocardia is a slowly growing organism; routine cultures usually.

Nocardia species have a thin layer of mycolic acid which retains the carbol fuchsin dye when using a weaker acid for decolorization (i.e. modified acid fast stain). This feature helps distinguish from other filamentous bacteria that stain negative with this procedure. Comment Here Reference: Nocardia Nocardia: Properties, Pathogenesis, Lab Diagnosis. Nocardia species are gram-positive, variably acid-fast, filamentous, and strictly aerobic organisms belonging to the actinomycetes group. Nocardia spp forms branched filaments that extend along the surface (substrate hyphae) and into the air (aerial hyphae). They are normal inhabitants of soil. Pulmonary nocardiosis is a severe and uncommon opportunistic infection caused by Nocardia species. We present a patient with cryptogenic organizing pneumonia who was receiving long-term immunosuppressive therapy, whose treatment course was complicated by cutaneous and pulmonary nocardiosis.

There are three commonly recognized species of Nocardia that cause disease in a large variety of animals including humans. In the United States, pulmonary or systemic nocardiosis in humans caused by N. asteroides is most frequently diagnosed. It should be noted that N. brasiliensis can cause nocardiosis also. In Central and South America mycetomas induced by N. brasiliensis appear to be more. The genus Nocardia was first discovered by Edmund Nocard, a French veterinarian, in 1889, as the main cause of bovine infections . The species of Nocardia genus are gram-positive and rod-shaped bacteria. Different species can range have colony colors from white, to tan, orange and even red in color. Colonies appear to be smooth or moist, and.

Nocardia species also cause infections in animals, including bovine mastitis and sporotrichoid nocardiosis in horses. When observed microscopically, either in Gram-stained smears of clinical specimens or cultures or on histopathology in tissues, Nocardia organisms are delicate, branching, beaded, filamentous, gram-positive bacteria with a. Nocardia species are thin, aerobic, gram-positive bacilli that form branching filaments. The bacteria stain irregularly and appear beaded on Gram stain. The speciation of Nocardia has been problematic. The original classification was based on the ability to use specific nutrients and to decompose substrates such as adenine, casein, urea.
Nocardia asteroides and Nocardia brasiliensis whole-cell extracts were used as antigens to generate monoclonal antibodies (MAbs). Six stable hybrid cell lines secreting anti-Nocardia spp. MAbs were obtained. These were characterized by enzyme-linked immunosorbent assay, Western blot (immunoblot), and immunofluorescence assay. Although all the MAbs exhibited different degrees of cross. Granules are most often seen in infections caused by N. brasiliensis, but also can be produced by other Nocardia species. Gram stain Gram staining is the most sensitive method by which to visualize and recognize Nocardia in clinial samples. Clinical specimens Beaded Gram positive rods, 0.5-1.0, thin, filamentous and typically right angle branching Nocardia brasiliensis Infection 165 isolates were identified as N. brasiliensis. Specia-tion was accomplished by the use of biochemical methods including casein hydroysis and xanthine and tyrosine utilization. The correct identity of several isolates was confirmed by the State Micro-biology Laboratory in Raleigh, North Carolina, o
CHARACTERISTICS: Nocardia are actinomycetes and there are over 70 species in the genus, of which ~ 25 species are pathogenic to humans (2). They are gram positive aerobic bacteria that are 0.5-1.0 μm in diameter with branched vegetative hyphae that split into pleomorphic rods and cocci (2,3,4). SECTION II - HAZARD IDENTIFICATION 1 Introduction. Mycetoma is a chronic infectious disease that may be produced by fungi or by bacteria. Pinoy in 1913 named eumycetoma those cases, produced by fungi and actinomycetoma, where the etiologic agent has been a bacterium .In Mexico more than 90% of mycetoma cases are produced by bacteria such as Nocardia brasiliensis.However, Actinomadura madurae, Streptomyces somaliensis, Nocardia. Nocardia asteroides is the most prevalent pathogen, although infection with N. brasiliensis has been described. [ 4 , 7 , 8 ] Our patient presented with the fourth subtype of cutaneous nocardiosis.
