This study investigated the occurrence of various opportunistic pathogens (OPs) through four drinking water treatment and distribution systems in eastern China. Conventional trains involving coagulation/sedimentation, filtration, disinfection efficiently removed total coliforms from 1700 to 2300 CFU/L influent undetectable levels treated tap water. However, culture-independent qPCR analysis det...

The transmissible plasmid pAMbeta1, which codes for erythromycin and lincomycin resistance, was conjugally transferred from a Lancefield group F Streptococcus to a strain of Streptococcus avium. Both organisms served as pAMbeta1 donors for three strains of Lactobacillus casei. Introduction of pAMbeta1 into one of the L. casei strains caused the organism to lose its native 6.7 X 10(6)-dalton pla...

Campylobacter avium is a thermotolerant Campylobacter species that has been isolated from poultry. C. avium was also the second hippuricase-positive species to be identified within Campylobacter Here, we present the genome sequence of the C. avium type strain LMG 24591 (=CCUG 56292T), isolated in 2006 from a broiler chicken in Italy.

A commercial DNA probe procedure for identification of Mycobacterium avium complex isolates was evaluated for accuracy and applicability for use in the clinical laboratory. The test (Gen-Probe Rapid Diagnostic System for Mycobacterium Avium Complex; Gen-Probe Corp., San Diego, Calif.) uses hybridization in solution of two 125I-labeled cDNA probes. One probe is complementary to rRNA from M. aviu...

SETTING Mycobacterium avium complex organisms have not been isolated from late stage AIDS patients in Uganda. This could possibly be due to the absence of M. avium complex in the Uganda environment. OBJECTIVE AND DESIGN Determine whether M. avium complex organisms could be isolated from water and soils collected in the living environment of Ugandan AIDS patients. RESULTS Representatives of ...

Organisms of the Mycobacterium avium complex cause disseminated blood-borne infection in patients with AIDS, who acquire the infection mainly through the gastrointestinal tract. Prior to causing infection, M. avium must colonize and invade the intestinal mucosa. This study examined the ability of several serovars of the M. avium complex to bind to and invade the HT-29 intestinal mucosal cell li...

Sweet cherry (Prunus avium L.) is an important fruit crop in which fruit size is strongly associated with commercial value; few genes associated with fruit size have, however, been identified in sweet cherry. Members of the CYP78A subfamily, a group of important cytochrome P450s, have been found to be involved in controlling seed size and development in Arabidopsis thaliana, rice, soybean, and ...

The FASTPlaqueTB assay is an established diagnostic aid for the rapid detection of Mycobacterium tuberculosis from human sputum samples. Using the FASTPlaqueTB assay reagents, viable Mycobacterium avium subsp. paratuberculosis cells were detected as phage plaques in just 24 h. The bacteriophage used does not infect M. avium subsp. paratuberculosis alone, so to add specificity to this assay, a P...

BACKGROUND Cellulitis caused by Mycobacterium avium-intracellulare has rarely been described. Mycobacterium avium-intracellulare is a rare cause of septic arthritis after intra-articular injection, though the causative role of injection is difficult to ascertain in such cases. CASE PRESENTATION A 57-year-old with rheumatoid arthritis treated with prednisone and azathioprine developed bilatera...

A rapid and quantitative assay for the disinfection of the water-borne pathogen, Mycobacterium avium, was developed using firefly luciferase as a reporter gene. There was a correlation between the quantity of light produced and the number of colony-forming units. In chlorine-disinfection studies of a luciferase-carrying derivative of M. avium, there was a strong correlation (r2=0.96) between co...
