Molecular Characterization of Staphylococcus Aureus Enterotoxins in Milk and Some Dairy Products

  title={Molecular Characterization of Staphylococcus Aureus Enterotoxins in Milk and Some Dairy Products},
  author={Noha A. Afifi and A. Sadek and M. Aggour and M. M. Nemr},
Background: Staphylococcus enterotoxins (SEs) are superantigenic toxins responsible for food poisoning in human and lead to high incidence of food poisoning outbreaks. The only previously known toxins were the five major classical types SEA to SEE. New types have been identified such as SEG and SEH. Objective: The aim of this work was to evaluate the percentage of S. aureus and enterotoxin productivity in milk and some dairy products, and to characterize the genes encoding some of the classical… Expand
Assessment of exposure to staphylococcal enterotoxins genes by consumption of ready to consume milk products in milk shop outlets in Mbeya, Tanzania
This study assessed the exposure of humans to Staphylococcus species expressing the Enterotoxins genes (SEs) through consumption of boiled-milk-served-hot and fermented milk in Mbeya, Tanzania. AExpand
Isolation of Staphylococcus aureus from Ice-Cream Samples
The Staphylococci are ubiquitous in nature, with humans and animals as the primary reservoirs. They are present in the nasal passages and throat, in the hair, and on the skin of probably 50% or moreExpand
Ice cream is a frozen dairy product. Ice cream has an outstanding nutritional quality, but is also an excellent medium for bacteria growth. The study was conducted to evaluate the bacteriologicalExpand


PCR detection of staphylococcal enterotoxin genes in Staphylococcus aureus strains isolated from raw and pasteurized milk.
With the recent identification of newSEs, the perceived frequency of enterotoxigenic strains has increased, suggesting that the pathogenic potential of staphylococci may be higher than previously thought; however, further studies are required to assess the expression of these new SEs by S. aureus.

Detection of classical enterotoxins and identification of enterotoxin genes in Staphylococcus aureus from milk and dairy products.
The distribution of genes encoding staphylococcal enterotoxins (SE) in S. aureus isolated from bovine, goat, sheep and buffalo milk and dairy products was verified by the presence of the corresponding SE production. Expand
Enterotoxigenic coagulase positive Staphylococcus in milk and milk products, lben and jben, in northern Morocco.
The finding of a pathogen such as staphylococci-producing SEs and containing se genes in milk and milk products in northern Morocco may indicate a problem for public health in this region. Expand
Coagulase-positive Staphylococci and Staphylococcus aureus in food products marketed in Italy.
An investigation on the presence of Coagulase-Positive Staphylococci and S. aureus in several food products marketed in Italy and on food contact surface swabs sampled from the food industry highlighted that these organisms constitute a potential risk for consumers' health. Expand
Distribution of newly described enterotoxin-like genes in Staphylococcus aureus from food.
The high prevalence of newly discovered enterotoxin genes, including the genes encoding emetic toxins, was demonstrated in food-derived strains, supporting the need for additional work on its role in food poisoning and, alternatively, to monitor its presence in S. aureus isolated from food. Expand
Enterotoxin production and DNA fingerprinting in Staphylococcus aureus isolated from human and food samples. Relations between genetic types and enterotoxins.
A total of 224 Staphylococcus aureus strains from human carriers and manually handled foods collected in the Principality of Asturias, Spain over 1995-1999 were analysed for the production of enterotoxins and a good relation between detection of SEs and their ent genes was found. Expand
Characterisation of Staphylococcus aureus strains isolated from cows' milk
The aim of the study was to characterise the Staphylococcus aureus strains isolated from unprocessed cow’s milk for staphylococcal superantigenic toxin genes (sea-selu and tst), to examine theExpand
Enterotoxin production by Staphylococcus aureus isolated from mastitic cows.
To determine whether staphylococci causing bovine mastitis could cause human foodborne intoxication, the production of staphlyococcal enterotoxins A through D by 160 S. aureus isolates was evaluated with the use of a reverse passive latex agglutination enterotoxin kit. Expand
PCR primers for the detection of staphylococcal enterotoxins K, L, and M and survey of staphylococcal enterotoxin types in Staphylococcus aureus isolates from food poisoning cases in Taiwan.
In an attempt to survey the distribution of classical and new SEs in organisms responsible for staphylococcal infections in Taiwan, PCR primers for the genes that define the SEK, SEL, and SEM types are developed and surveyed. Expand
Antibiogram and coagulase diversity in staphylococcal enterotoxin-producing Staphylococcus aureus from bovine mastitis.
Based on coagulase gene polymorphisms, a broad distribution of identical or closely related enterotoxin-producing Staph. Expand
