Nocardia farcinica is a species of bacteria and a member of the genus Nocardia. This species is very similar in phenotype to Nocardia asteroides, to the degree that some isolates of N. asteroides were later found to be Nocardia farcinica. N. farcinica may be a causative agent of nocardiosis or of secondary infections in immunocompromised patients. Strains of this species have been isolated from human brain abscesses. N. farcinica contains a 6 million base pair genome with an average GC content of 70.8%. A sequenced strain, IFM 10152, is also known to contain two plasmids, pNF1 pNF2. The chromosome encodes 5,674 potential protein-coding open reading frames. This genome may have undergone numerous gene duplication events as a result of adapting to new environments. Parte, A.C.

Nocardia is an opportunistic pathogen that causes respiratory infections in immunocompromised patients. The aim of this study was to analyze the epidemiology, clinical significance and antimicrobial susceptibility of Nocardia species isolated from eight children with cystic fibrosis. The isolated species were identified as Nocardia farcinica, Nocardia transvalensis, Nocardia pneumoniae, Nocardia veterana and Nocardia wallacei. N. farcinica was isolated in three patients and all of them presented lung affectation with a chronic colonization and pneumonia. N. farcinica showed resistance against gentamicin, tobramycin, cefotaxime, but was susceptible to trimethoprim-sulfamethoxazole and amikacin. N. transvalensis, which was isolated from two patients, showed an association with chronic colonization. N. transvalensis was resistant to tobramycin and amikacin, but susceptible to ciprofloxacin, trimethoprim-sulfamethoxazole and cefotaxime. N. veterana, N. pneumoniae and N. wallacei were isolated from three
A soil isolate, strain F829T, which had provisionally been assigned to the genus Nocardia, was subjected to a polyphasic taxonomic study. An almost complete 16S rDNA sequence was determined for this strain; the sequence was aligned with available sequences for nocardiae and phylogenetic trees were inferred using three tree-making algorithms. The organism showed a combination of phenotypic properties typical of nocardiae and formed a distinct phyletic line within the evolutionary radiation of species of the genus Nocardia, being most closely related to Nocardia asteroides ATCC 19247T. Strain F829T was readily distinguished from representatives of species of Nocardia with validly published names on the basis of phenotypic data, notably from the type strain of N. asteroides. It is proposed that the organism be recognized as a novel species of Nocardia, Nocardia caishijiensis sp. nov. The type strain is F829T (=AS 4.1728T =JCM 11508T).
Nocardia is a genus of weakly staining Gram-positive, catalase-positive, rod-shaped bacteria. It forms partially acid-fast beaded branching filaments (acting as fungi, but being truly bacteria). It contains a total of 85 species. Some species are nonpathogenic, while others are responsible for nocardiosis. Nocardia species are found worldwide in soil rich in organic matter. In addition, they are oral microflora found in healthy gingiva, as well as periodontal pockets. Most Nocardia infections are acquired by inhalation of the bacteria or through traumatic introduction. Nocardia colonies have a variable appearance, but most species appear to have aerial hyphae when viewed with a dissecting microscope, particularly when they have been grown on nutritionally limiting media. Nocardia grow slowly on nonselective culture media, and are strict aerobes with the ability to grow in a wide temperature range. Some species are partially acid-fast (meaning a less concentrated solution of sulfuric or ...

Nocardia is an infrequent but significant cause of infections in the immunocompromised host. Clinical syndromes are varied and ranges from pulmonary, disseminated, cutaneous, and CNS involvement. Here we describe a case of disseminated subcutaneous n
Nocardia are weakly gram-positive, filamentous bacteria found worldwide in soils. Human disease from this microbe was first described by Eppinger in 1890, after bovine disease was described by Nocard in 1888. Pathogenic Nocardia are members of the family Nocardiaceae, the aerobic actinomycetes.. Dissemination is usually from a pulmonary source. Nocardia asteroides is the principal cause of systemic nocardiosis in the United States. A constellation of acute and chronic symptoms develops, ranging from headache to obtundation, pyuria, and right upper abdominal pain due to hepatic involvement.. CNS infection may have no signs or symptoms or may present with focal neurological deficits, seizures, and coma.. Imaging findings, particularly on MRI, can lead to the diagnosis of infection rather than tumor. T2 hypointense rings with corresponding ring enhancement and restricted diffusion are characteristic imaging features of suggestive of abscess. DW imaging has been shown to be superior to conventional ...
The purpose of this study was to establish optimal molar glycerol to glucose ratio for enhanced biosurfactant synthesis by the cultivation of Nocardia vacсinii ІMV В-7405 on a mixture of energetically nonequivalent substrates (glucose and glycerol). Based on theoretical calculations of the energy requirements for biomass production and the synthesis of surface-active trehalose monomycolates on the energy-deficient substrate (glycerol), the concentration of the energy-excessive substrate (glucose), which increased the efficiency of the substrate carbon conversion to biosurfactant, was determined. It was found that the synthesis of extracellular biosurfactant on a mixture of glucose and glycerol at molar ratio of 1.0:2.5 increased 2.0-2.3-fold compared to that on corresponding monosubstrates. The increased level of biosurfactant on the mixed substrate is determined by intensification of surface-active trehalose monomycolate synthesis, confirmed by 1.2-5.7-fold increase in activity of the ...

The citrate cycle (TCA cycle, Krebs cycle) is an important aerobic pathway for the final steps of the oxidation of carbohydrates and fatty acids. The cycle starts with acetyl-CoA, the activated form of acetate, derived from glycolysis and pyruvate oxidation for carbohydrates and from beta oxidation of fatty acids. The two-carbon acetyl group in acetyl-CoA is transferred to the four-carbon compound of oxaloacetate to form the six-carbon compound of citrate. In a series of reactions two carbons in citrate are oxidized to CO2 and the reaction pathway supplies NADH for use in the oxidative phosphorylation and other metabolic processes. The pathway also supplies important precursor metabolites including 2-oxoglutarate. At the end of the cycle the remaining four-carbon part is transformed back to oxaloacetate. According to the genome sequence data, many organisms seem to lack genes for the full cycle [MD:M00009], but contain genes for specific segments [MD:M00010 M00011 ...
N. brasiliensis, N. otitidiscaviarum, and N. transvalensis represent the remaining 10% of infections. Of these, N. brasiliensis is the most important in tropical areas; it is most often seen as a cutaneous infection that can affect individuals with normal immune function (although 70% of cases of N. brasiliensis are seen in immunocompromised individuals).. In general, nocardiosis is a disease that affects primarily the cell- or humorally-immunocompromised population: transplant recipients, patients on high-dose steroids, and patients with cancer, AIDS, or other leukocyte deficiencies. Nocardia may also colonize the respiratory tract of immunocompetent individuals with compromised pulmonary function, such as those with asthma or chronic obstructive pulmonary disease (COPD). Once established, nocardial pneumonia will usually disseminate hematologically, with kidney, skin, GI tract, and brain being common targets; brain abscess (33% of cases) is the most common presentation.

BACKGROUND Opportunistic infections may occur when patients with inflammatory bowel disease (IBD) are treated with tumor necrosis factor (TNF)-alpha inhibitors. With the increasing use of new immunosuppressant drugs, the incidence of opportunistic or atypical infections is also increasing, including with Nocardia spp. A high level of awareness of atypical infections is warranted in immunosuppressed patients. CASE REPORT A 57-year-old female African American, with a past medical history of ulcerative colitis (UC) and arthritis, was treated with infliximab and prednisone. She presented to the emergency department with acute onset of chest pain, shortness of breath, and a two-week history of a productive cough. Examination showed hypoxia, tachypnea, decreased and coarse bilateral breath sounds, and fluctuant, tender, erythematous masses on her trunk and groin. Laboratory investigations showed a leukocytosis with a left shift. She was initially treated for presumed community-acquired pneumonia (CAP).

Primary growth of AMC 60 fibrosarcoma inoculated into the hind leg of ACI/N rats resulted in occasional generation of concomitant resistance to growth of a second graft of the same tumor cells in the peritoneal or pleural cavity. Using this syngeneic tumor-host system, experiments were carried out to elucidate the effect of intratumoral injections of an immunomodulator, Nocardia rubra cell wall skeleton (N-CWS), on concomitant immunity. Rats bearing a solid tumor into which N-CWS was repeatedly injected showed a significant inhibitory effect on the proliferation of the tumor cells inoculated secondarily into the peritoneal cavity, i.e., concomitant immunity, as compared to control groups of normal, N-CWS-treated and solid tumor-bearing rats. Peritoneal macrophages, when harvested after i.p. tumor inoculation into the N-CWS treated solid tumor-bearing rats, were found to be significantly potentiated for tumoricidal activity against [5-125I]iodo-2′-deoxyuridine-labeled AMC tumor cells. These ...
The purpose of this study was to determine whether the presence of progressively growing pulmonary metastases influences the number and function of alveolar macrophages (AM). Female F344 rats were given i.v. injections of cells from a metastatic variant line of the syngeneic adenocarcinoma MADB-105. At Days 7, 14, 21, and 28 after injection, normal and tumor-bearing animals (3/group) were killed, and their AM were harvested by lavage. The functional integrity of AM was determined by their capacity to phagocytose opsonized erythrocytes and by their ability to respond to a variety of activating agents in vitro. Normal and metastasis-bearing rats were given i.v. injections of Nocardia rubra cell wall skeleton to determine whether the presence of large pulmonary metastases would interfere with AM activation in situ. The data demonstrated that the presence of progressively growing lung metastases led to a slight increase in the number of harvested AM and that these cells from tumor-bearing rats were ...
Central venous catheters, often needed by cancer patients, can be the source of Nocardia bacteremia. We evaluated the clinical characteristics and outcomes of 17 cancer patients with Nocardia bacteremia. For 10 patients, the bacteremia was associated with the catheter; for the other 7, it was a disseminated infection. N. nova complex was the leading cause of bacteremia. Nocardia promoted heavy biofilm formation on the surface of central venous catheter segments tested in an in vitro biofilm model. Trimethoprim- and minocycline-based lock solutions had potent in vitro activity against biofilm growth. Patients with Nocardia central venous catheter-associated bloodstream infections responded well to catheter removal and antimicrobial drug therapy, whereas those with disseminated bacteremia had poor prognoses ...

Diagnosis may be difficult. In the clinical laboratory, routine cultures may be held for insufficient time to grow nocardiae, and referral to a reference laboratory may be needed for species identification. Recently, N. farcinica and N. nova have been removed from N.asteroides complex. N. farcinica frequently is more resistant to antimicrobial agents, including trimethoprim-sulfamethoxazole (TMP-SMX) (the drug of choice), and has been shown to be more virulent in an animal model. TMP-SMX therapy for HIV-infected patients may be complicated by frequent occurrence of side effects and drug resistance ...
Bacteria capable of degrading polymeric products were isolated from several sources including tap water, sediment, and a deteriorated polymeric product. Alcaligenes xylosoxidans; T2, Pseudomonas aeruginosa GP10, and Nocardia corynebacterioides S3 were able to utilize rubber products as a sole source of carbon and energy. These microorganisms showed different growth patterns in mineral salt media (MSM) supplemented with rubber strips or with the rubber extract. A. xylosoxidans T2, P. aeruginosa GP10 and N. corynebacterioides S3 reduced the weight of the rubber product by approximately 2.0, 4.0 and 5.3%, respectively, after 70 days of incubation with the rubber product in MSM. On average, 0.45 mg (water-soluble carbon) g(-1) of the rubber product was released into solution phase after 7 days of incubation. Growth of N. corynebacterloides S3 was initially slower but exceeded the other two bacteria upon colonization of the polymer products. N. corynebacterioides S3 formed a dense biofilm on surfaces ...

A 59 year old Japanese plumber was referred to the Hirosaki Central Hospital because of pyothorax and sustained high fever. He had a history of repeated bouts of pyothorax, but no possible causative agent was discovered. He had been treated with wide spectrum antibiotics and drainage. Previously, he was once diagnosed as having diabetes, but no medical treatment was undertaken. His family history was not remarkable. The peripheral white blood cell count was 9070/mm3 (neutrophils, 84.3%; eosinophils, 2.6%; basophils, 0.2%; monocytes, 5.2%; and lymphocytes, 7.7%). Red blood cell and platelet counts were normal. The erythrocyte sedimentation rate was increased to 38 mm at one hour, and C reactive protein was increased to 3.99 (normal, , 3.0 mg/litre). The blood glucose concentration was normal, as was the oral glucose tolerance test. A skin test for tuberculin was negative. There was no evidence of immunocompromised status.

This chapter discusses some of the stressors likely to target the cell envelope of Mycobacterium tuberculosis during infection, and the corresponding regulatory elements expressed by the bacterium to counteract this stress. Phylogenetically, M. tuberculosis is a member of the phylum Actinobacteria, which also includes several notable human pathogens, including species of the genera Streptomyces, Corynebacterium, Nocardia, and Rhodococcus. M. tuberculosis is a facultative intracellular pathogen, and its host range is restricted to humans. The bacterium is not normally found free within the environment, so its continued survival within the human population requires that it be transmitted directly from an infected individual with active disease to one that is susceptible to infection. Posttranslational phosphorylation of proteins was traditionally thought to be limited to eukaryotic cells. However, the discovery of two-component signal transduction systems (TCSSs) in bacteria shifted this paradigm to

IVET is a powerful gene manipulation strategy for discovering which genes in an organism (a pathogen, usually) are up-regulated or turned on during host infection. Lets say youre studying a new pathogen and you want to get an idea of which genes, in the pathogen, are turned on during the infection process. First, you need a strain of the organism thats disabled by virtue of lacking a working copy of a particular metabolic enzyme, say an enzyme needed for purine metabolism, e.g. purA. Secondly, you need a vector for inserting a promoterless copy of the working gene into the bacterium. What this usually means is, you need a plasmid (a small extra chromosome; many bacteria have them, and they can often be manipulated in the lab) on which to place a functional purA gene. The gene wont be expressed, however, if it lacks a suitable promoter region on the DNA upstream of the gene. Thats good; thats what you want. You want to put a promoterless copy of the good gene on the plasmid, along with ...
