Three Gram-stain-negative, rod-shaped, non-spore-forming bacteria, BA1 T , Q614 and PB68.1 isolated from the digestive system of Heterorhabditis entomopathogenic nematodes, were biochemically molecularly characterized to clarify their taxonomic affiliations. The 16S rRNA gene sequences these strains suggest that they belong Gammaproteobacteria, family Morganellacea genus Photorhabdus . Deeper a...
A serological study of twenty three European bison (Bison bonasus) derived from Northern-East Poland for the seroprevalence of Mycobacterium avium subsp. paratuberculosis, Mycoplasma bovis, Mycoplasma mycoides subsp. mycoides SC, Mycoplasma agalactiae and Mycoplasma capricolum subsp. capripneumoniae was conducted. Only specific antibodies to M. bovis were detected in two animals (8.7%) which we...
A mosquitocidal toxin gene, cloned from Bacillus thuringiensis subsp. israelensis, was introduced into mutant crystal-negative B. thuringiensis subsp. israelensis cells. Partial toxicity to mosquitos was restored. The 58-kilodalton cloned gene product is a minor protein component of B. thuringiensis subsp. israelensis crystals and is structurally related to a major, 135-kilodalton crystal toxin.
Electron microscopy of Bacillus thuringiensis subsp. kyushuensis revealed that the parasporal inclusions are composed of a homogeneous center surrounded by a thick, electron-dense coating. Antibodies directed against the 135- and 65-kilodalton B. thuringiensis subsp. israelensis peptides cross-reacted with the 70- and 26-kilodalton peptides, respectively, of B. thuringiensis subsp. kyushuensis.
جنس Noaea در ایران مورد بررسی قرار گرفته است. هر 3 گونه شناخته شده از ایران تشخیص داده میشود. گونه N. mucronata با 3 زیر گونه زیر فراوانترین گونه است. subsp. leptoclada ، subsp. tournefortii، subsp. mucronata زیر گونهN. mucronata subsp. leptoclada ترکیب جدیدی است. گونهN.major وN. minuta گیاهانی یکساله با انتشار محدودی هستند که برای اولین بار از ایران گزارش میشوند.
With the genome sequence of Mycobacterium avium subsp. paratuberculosis determined, technologies are now being developed for construction of protein arrays to detect the presence of antibodies against M. avium subsp. paratuberculosis in host serum. The power of this approach is that it enables a direct comparison of M. avium subsp. paratuberculosis proteins to each other in relation to their im...
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...
Mycobacterium avium subsp. paratuberculosis is shed into the milk and feces of cows with advanced Johne's disease, allowing the transmission of M. avium subsp. paratuberculosis between animals. The objective of this study was to formulate an optimized protocol for the isolation of M. avium subsp. paratuberculosis in milk. The parameters investigated included chemical decontamination with N-acet...
Enzyme-linked immunosorbent assays (ELISAs) for the diagnosis of Johne's disease (JD), caused by Mycobacterium avium subsp. paratuberculosis, were developed using whole bacilli treated with formaldehyde (called WELISA) or surface antigens obtained by treatment of M. avium subsp. paratuberculosis bacilli with formaldehyde and then brief sonication (called SELISA). ELISA plates were coated with e...
