The prevalence of Salmonella in southern Africa in farm feeds and by-products of animal origin during 1982-1988 was determined. Salmonella occurred in 5.18% of the farm feed samples and in 9.54% of the by-product samples. Different serovars were isolated, some only once. The findings underestimate the true prevalence of Salmonella in farm feeds and by-products, and is representative of only the...
Salmonellosis is one of the most frequently occurring food borne illness resulting from the ingestion of viable cells of a member of the genus Salmonella. Eggs, poultry, meat and meat products are reported to be the most common food vehicles of salmonellosis to humans (Oosterom, 1991; Jay, 1992; Davies and Wray, 1996). Human illness caused by infection with Salmonella spp. increased worldwide b...
The clinical phenotype of interleukin 12 receptor beta1 chain (IL-12Rbeta1) deficiency and the function of human IL-12 in host defense remain largely unknown, due to the small number of patients reported. We now report 41 patients with complete IL-12Rbeta1 deficiency from 17 countries. The only opportunistic infections observed, in 34 patients, were of childhood onset and caused by weakly virul...
Vaccines are the most powerful biologicals which have modulated the economic, social and cultural life of human beings. Certain diseases have haunted humanity for centuries but are now extinct due to vaccines. On the other hand, some diseases such as salmonellosis, that were uncontrollable in the past, still cause pandemics today. There are more than 2500 serovars of Salmonella and vaccines mad...
plasmids play an important role in the virulence and antibiotic resistance of salmonella. salmonella carry plasmids having different size and number. plasmid profile analysis of single isolates of salmonella typhimurium and salmonella enteritidis revealed the presence of 4- plasmid profiles. salmonella serovars produce several type iii secretions including sop-e and sop –b. soap e is detected b...
Non-typhoidal salmonellosis remains an important public health problem worldwide. Dogs may harbour Salmonella in their intestines and can easily shed Salmonella in the environment with the possibility of transmission to humans. Thus, monitoring is essential to understand the role of dogs in zoonotic transmission. The objectives of this study were to determine the shedding of Salmonella by owned...
Salmonella enterica is a common cause of human food borne gastroenteritis and bacteremia worldwide. Salmonellosis is caused by different serotypes of salmonella; humans and animals are generally infected with these bacteria by the consumption of contaminated food products (1-3). Non-typhi salmonella gastroenteritis in contrast to the invasive salmonellosis that requires prompt antibiotic therap...
BACKGROUND Salmonella is an infectious agents causing numerous cases of illness each year, and thereby having significant economic impact. Using returning Swedish travellers we estimated the burden of salmonellosis in different European countries. METHODS From the Swedish database on notifiable communicable diseases 15,864 cases with travel-associated salmonellosis acquired in Europe from 199...
