In 1989 and 1990, a case-control study designed to identify risk factors for sporadic infections with thermotolerant Campylobacter bacteria was conducted in three counties southeastern Norway. The investigation confined which were acquired A total of 52 bacteriologically confirmed cases 103 controls matched by age, sex, geographic region interviewed. following found be independently associated illness conditional logistic regression analysis: consumption sausages at barbecue (odds ratio [OR]...
An epidemiological investigation was conducted to identify risk factors related hygiene and husbandry practices which determine the introduction of Campylobacter spp. into broiler chicken flocks. All 176 farms in an area southeastern Norway participated study. Each farm represented by one flock selected at random during a one-year period. The flocks were examined for campylobacter colonization slaughter, managers subsequently interviewed about practices. recovered from 32 (18%) proportion...
Immunomagnetic separation with immunomagnetic beads was used to isolate strains of Listeria monocytogenes both from pure cultures and heterogeneous suspensions. The monoclonal antibodies recognized all six serotype 4 but only one three 1. Coating procedure, incubation time, number influenced the sensitivity isolation method. Less than 1 x 10(2) bacteria per ml in less 2 enriched foods could be detected. method represents a new approach extraction pathogenic directly foods, after...
Cattle brucellosis has significant economic and zoonotic implication for the rural communities in Ethiopia consequence of their traditional life styles, feeding habits disease patterns. Hence, knowledge occurrence livestock husbandry practice considerable importance reducing public health impacts disease. A total 1623 cattle sera were serially tested using rose Bengal test as screening complement fixation confirmatory tests. The Stata survey command was used to establish prevalences overall...
Antimicrobial resistance (AMR) is a global public health crisis. This study assessed the general public's consumption of antibiotics and associated factors in Lusaka district Zambia.
A two-step polymerase chain reaction (PCR) procedure with two nested pairs of primers specific for the yadA gene Yersinia enterocolitica was developed. The PCR assay identified all common pathogenic serogroups (O:3, O:5,27, O:8, O:9, O:13, and O:21) from three continents differentiated Y. pseudotuberculosis a variety nonpathogenic yersiniae representing 25 four species. performance method evaluated seeded food water samples. We compared procedures sample preparation prior to PCR: one based...
We have identified a clonal complex of Mycobacterium bovis present at high frequency in cattle population samples from several sub-Saharan west-central African countries. This closely related group bacteria is defined by specific chromosomal deletion (RDAf1) and can be the absence spacer 30 standard spoligotype typing scheme. named this strains 1 (Af1) signature as being same M. BCG vaccine strain but with 30. Strains Af1 were found Mali, Cameroon, Nigeria, Chad, using combination...
Background Q fever is caused by the obligate intracellular bacterium, Coxiella burnetii [1,2]. This disease regarded as endemic worldwide, with exception of New Zealand [3-6]. Cattle, sheep and goats are considered to be primary source transmission for humans [7,8]. Humans infected mainly inhalation contaminated aerosols or ingestion milk and/or fresh dairy products. In animals, subclinical but has especially been associated reproductive disorders such late abortions, stillbirths, weak off...
Abstract This is the first comprehensive study on occurrence and distribution of piscine reovirus ( PRV ) in Atlantic salmon, Salmo salar L., caught Norwegian rivers. a newly discovered associated with heart skeletal muscle inflammation HSMI ), serious commercially important disease affecting farmed salmon Norway. A cross‐sectional survey based real‐time RT ‐ PCR screening head kidney samples from wild, cultivated escaped 2007 to 2009 rivers has been conducted. In addition, anadromous trout...
The importance of non-tuberculous mycobacteria (NTM) infections in humans and animals sub-Saharan Africa at the human-environment-livestock-wildlife interface has recently received increased attention. NTM are environmental opportunistic pathogens animals. Recent studies pastoral ecosystems Uganda detected with cervical lymphadenitis cattle lesions compatible bovine tuberculosis. However, little is known about source these Uganda. aim this study was to isolate identify environment...
