| distribution of mycobacterium avium complex isolates in tissue samples of pigs fed peat naturally contaminated with mycobacteria as a supplement. | in early 1999, there was an increased incidence of tuberculous lesions in the lymph nodes of slaughtered pigs in the czech republic. in part 1 of this study, tuberculous lesions were detected in 140 (62%) tissue samples collected from pigs coming from 15 farms in 15 districts at routine veterinary meat inspections in abattoirs. mycobacteria were isolated from 37 (16%) tissue samples: 34 mycobacterium avium subsp. hominissuis isolates and three environmentally derived mycobacteria. in search of i ... | 2005 | 15750094 |
| new probes used for is1245 and is1311 restriction fragment length polymorphism of mycobacterium avium subsp. avium and mycobacterium avium subsp. hominissuis isolates of human and animal origin in norway. | mycobacterium avium is an environmental mycobacterium that can be divided into the subspecies avium, hominissuis, paratuberculosis and silvaticum. some m. avium subspecies are opportunistic pathogens for animals and humans. they are ubiquitous in nature and can be isolated from natural sources of water, soil, plants and bedding material. isolates of m. avium originating from humans (n = 37), pigs (n = 51) and wild birds (n = 10) in norway were examined by is1245 and is1311 rflp using new and spe ... | 2007 | 17335590 |
| comparison of variable-number tandem-repeat markers typing and is1245 restriction fragment length polymorphism fingerprinting of mycobacterium avium subsp. hominissuis from human and porcine origins. | animal mycobacterioses are regarded as a potential zoonotic risk and cause economical losses world wide. m. avium subsp. hominissuis is a slow-growing subspecies found in mycobacterial infected humans and pigs and therefore rapid and discriminatory typing methods are needed for epidemiological studies. the genetic similarity of m. avium subsp. hominissuis from human and porcine origins using two different typing methods have not been studied earlier. the objective of this study was to compare th ... | 2010 | 20219093 |
| [avian mycobacteriosis in humans remains a threat in the czech republic]. | the members of mycobacterium avium complex belong to the most common agents causing mycobacterioses in humans. they are classified as a potentially patogenic mycobacteria, although mycobacterium avium subsp. avium represent veterinary and economic risks in birds (mainly poultry) as well as mammals (pigs etc.). infected animals and their products (mainly eggs) often come from small household production and pose a risk for human health. the second member of this complex, mycobacterium avium subsp. ... | 2010 | 20401832 |
| is1245 rflp-based genotyping study of mycobacterium avium subsp. hominissuis isolates from pigs and humans. | mycobacterium avium subsp. hominissuis, ubiquitous environmental mycobacterium, is an opportunistic pathogen that is regularly isolated from pigs and humans in slovenia. genetic diversity of 114 isolates from pigs (n = 57) and humans (n = 57), identified by means of bacteriology, dna-rna hybridization techniques, is901 pcr and is1245 pcr, was investigated in this study, using is1245 restriction fragment length polymorphism (rflp) analysis. identical is1245 rflp profiles were found in isolates fr ... | 2008 | 18243315 |
| genetic diversity of mycobacterium avium subsp. hominissuis strains isolated from humans, pigs, and human living environment. | mycobacterium avium subsp. hominissuis (mah) strains are genetically diverse and cause infections in pigs and humans. to elucidate the geographical and host-dependent variations in the genetic diversity of mah, we performed variable numbers of tandem repeat (vntr) analysis targeting 19 loci for mah samples from humans (n=146), bathroom environments (n=37), and pigs (n=75) in japan; these data were then compared with previously reported vntr data from other countries. the minimum spanning tree (m ... | 2011 | 21745597 |

| comparative macrorestriction and rflp analysis of mycobacterium avium subsp. avium and mycobacterium avium subsp. hominissuis isolates from man, pig, and cattle. | in germany, tuberculous lesions in slaughtered pigs due to infection with members of the mycobacterium avium complex are increasingly reported. contaminated food originating from pig or other livestock is discussed as potential source of human infection. m. avium isolates from man (n=45), pig (n=29), and cattle (n=13) were characterised by restriction fragment length polymorphism (rflp) with respect to insertion sequences is1245 and is901 as well as by xbai-based pulsed-field gel electrophoresis ... | 2006 | 16797885 |
| impact of sawdust and wood shavings in bedding on pig tuberculous lesions in lymph nodes, and is1245 rflp analysis of mycobacterium avium subsp. hominissuis of serotypes 6 and 8 isolated from pigs and environment. | among 25,027 slaughter pigs raised in two farms, tuberculous lesions were detected in the lymph nodes of 898 (3.6%) of them. tuberculous lesions were most commonly found in the mesenteric (601; 2.4%) and head (451; 1.8%) lymph nodes. mycobacteria were isolated from 49 of 120 randomly selected mesenteric, head and bronchial lymph nodes with diagnosed tuberculosis originating from both farms. forty six mycobacterium avium subsp. hominissuis, one m. chelonae and two m. fortuitum isolates were found ... | 2004 | 15327797 |
| epidemiological investigation of a mycobacterium avium subsp. hominissuis outbreak in swine. | mycobacterium avium subsp. hominissuis (mah) infection in swine may cause granulomatous lesions in lymph nodes that must undergo differential diagnosis with those caused by m. tuberculosis complex members. moreover, mah outbreaks can lead to severe economic losses due to condemnation of carcasses. a number of potential sources of infection for animals can usually be identified in contaminated farms. this report describes the application of several molecular characterization techniques in order t ... | 2011 | 20653991 |
