Immunological diagnosis of Mycobacterium bovis infection of cattle is often confounded by cross-reactive responses resulting from exposure to other mycobacterial species, especially Mycobacterium avium. Early secretory antigenic target 6 (ESAT-6) and culture filtrate protein 10 (CFP-10) are dominant gamma interferon (IFN-gamma)-inducing antigens of tuberculous mycobacteria, and they are absent ...
In this study, a new bacterial strain having a high ability to produce γ-aminobutyric acid (GABA) was isolated from naturally fermented scallop solution and was identified as Enterococcus avium. To the best of our knowledge, this is the first study to prove that E. avium possesses glutamate decarboxylase activity. The strain was then mutagenized with UV radiation and was designated as E. avium ...
Members of the Mycobacterium avium complex (MAC) are ubiquitous bacteria that can be found in water, food, and other environmental samples and are considered opportunistic pathogens for numerous animal species, mainly birds and pigs, as well as for humans. We have recently demonstrated the usefulness of a PCR-based mycobacterial interspersed repetitive-unit-variable-number tandem-repeat (MIRU-V...
Cherry laurel (Laurocerasus officinalis Roemer Syn: Prunus laurocerasus L.) is a perennial wild fruit plant that is widely distributed in and around South-Eastern Black Sea, Marmara Sea, the Caspian Sea in the North and the East. However, breeding success of cherry laurel depends on early harvest, transient differences in taste, fruit color and flavor due to large number of biotic and abiotic s...
Previously, we had described the structures of the haptenic oligosaccharides of the surface glycopeptidolipid antigens from serotypes 9 and 25 of the Mycobacterium avium complex and had synthesized these units as putative antigenic probes. The lack of chemical concordance between the synthetic products and the haptens has prompted a re-examination of these structures utilizing the instrumental ...
The incidence of Mycobacterium avium-Mycobacterium intracellulare complex infections has increased in recent years primarily because a significant proportion of acquired immunodeficiency syndrome patients develop disseminated M. avium complex disease. In an effort to develop new tools to study these infections, we have produced eight monoclonal antibodies directed against M. avium. Western blot...
Mycobacterium avium-M. intracellulare is a frequent cause of late disseminated infection in patients with AIDS. The ability of human peripheral blood monocytes to phagocytose and kill M. avium was examined in an in vitro model. Monocytes were obtained from 13 healthy volunteers and 11 patients with AIDS, three of whom had documented disseminated M. avium infection. Monocytes were precultured fo...
In an attempt to clarify the taxonomy of the Mycobacterium avium complex, the relationship between IS1245 RFLP, growth temperature, 16S rDNA signature sequences and the 16S-23S rDNA internally transcribed spacer (ITS) of 160 M. avium-complex isolates from different sources was investigated. All 70 isolates identified as M. avium by INNO-LiPA MYCOBACTERIA (Innogenetics, Belgium), a DNA probe tes...
Infection with Mycobacterium avium subsp. paratuberculosis causes Johne's disease in cattle and is also implicated in cases of Crohn's disease in humans. Another closely related strain, M. avium subsp. avium, is a health problem for immunocompromised patients. To understand the molecular pathogenesis of M. avium subspecies, we analyzed the genome contents of isolates collected from humans and d...
A multiplex PCR designed to differentiate Mycobacterium tuberculosis complex organisms from M. avium and M. intracellulare was used to test 105 isolates identified by DNA probe methods as M. avium, M. intracellulare, or M. avium complex type X. The multiple PCR correctly identified 33 of 34 isolates identified by commercial probe methods as M. avium and all 51 isolates identified as M. intracel...
