TOXIC SHOCK SYNDROME
Provedor de dados: 79
Autores: BERGDOLL,M. S.
Toxic shock syndrome is a staphylococcal disease caused by toxins produced by the staphylococci, toxic shock syndrome toxin-1 and enterotoxin B. The disease results from staphylococci growing in the vagina with the use of tampons during menstruation, primarily in young women. However, any staphylococcal infection can result in toxic shock syndrome if the staphylococci produce the appropriate toxins and the individual has no antibodies to the toxins. The symptoms can be quite severe, with high fever, low blood pressure, diffuse macular erythroderma, orthostatic dizziness, vomiting and or diarrhea at the onset, severe myalgia, peeling of the skin of the palms of the hands and the soles of the feet after seven to ten days, and death in some cases. The disease...

Low cost production and purification of polyclonal antibodies to staphylococcal enterotoxin A
Provedor de dados: 59
Autores: Oliveira,Tereza Cristina R.M. de; Hirooka,Elisa Yoko.
An immunization scheme for production of antiserum to staphylococcal enterotoxin A (SEA) is proposed. The reference method of Robbins and Bergdoll was modified to reduce the number of doses and the amount of toxin used per animal. The best immunization scheme used injections in days 0, 8, 24, 59, 62 and 67. The amount of toxin at each injection was 5, 6, 20, 50, 100 and 200&lt;FONT FACE="Symbol"&gt;m&lt;/font&gt;g, respectively. The total amount of toxin was 381&lt;FONT FACE="Symbol"&gt;m&lt;/font&gt;g, which corresponded to a reduction of 107&lt;FONT FACE="Symbol"&gt;m&lt;/font&gt;g in the amount of toxin for each animal when compared to the reference method. The average antiserum titer using the Optimum Sensitivity Plate - OSP was 1:60 and using ELISA...

Enterotoxigenic Escherichia coli (ETEC) is recognized as the main cause of bacterial diarrhoea among children in Asia, Africa and Latin America but less investigated in Bolivia. OBJECTIVE: To determine the relation between enterotoxins, CFs and serotypes as well as the antimicrobial resistance patterns in a set of ETEC isolates collected from hospitalized children with acute diarrhea. In the present study we characterized 43 ETEC strains isolated from 2002 to 2006 from hospitalized children (0-5 years) with acute diarrhea in Bolivia. The strains were analyzed for heat-labile (LT) and heat-stable (ST) enterotoxins and colonization factor (CF) profiles, as well as for serogroups and antimicrobial resistance using phenotypic (ELISA, dot blot, slide...

Ocurrence of Staphylococcus aureus and multiplex pcr detection of classic enterotoxin genes in cheese and meat products
Provedor de dados: 58
Autores: Pelisser,Marcia Regina; Klein,Cátia Silene; Ascoli,Kelen Regina; Zotti,Thaís Regina; Arisi,Ana Carolina Maisonnave.
Multiplex PCR was used to investigate the presence of enterotoxins genes (sea, seb, sec, sed and see) and femA gene (specific for Staphylococcus aureus) in coagulase-positive staphylococci (CPS) isolated from cheese and meat products. From 102 CPS isolates, 91 were positive for femA, 10 for sea, 12 for sed and four for see.

Detection of enterotoxins genes in coagulase-negative staphylococci isolated from foods
Provedor de dados: 58
Autores: Cunha,Maria de Lourdes Ribeiro de Souza da; Peresi,Eliana; Calsolari,Regina Adriana Oliveira; Araújo Júnior,João Pessoa.
Staphylococcal food poisoning is caused by ingestion of enterotoxins preformed in the food contaminated essentially through human manipulation or raw material obtained from animals. Although coagulase-positive Staphylococcus aureus is the main agent responsible for food intoxication, some researches emphasise that coagulase-negative staphylococci (CNS) are able to produce staphylococcal enterotoxins and may be a potential cause of food poisoning. In the present study CNS were isolated from foods and the toxigenic capacity of the strains determined. A total of 88 food samples were analysed and 22.7% were positive for CNS strains. Staphylococcal counts ranged from 3.0 x 10² to 1.4 x 10(6) CFU/g or mL of food examined. S. epidermidis predominated among the...

ABSTRACT: The present study focused on isolation Bacillus cereus during the UHT milk production and shelf life, to assess the enterotoxigenic production capacity of isolates and to evaluate the use of the RAPD-PCR technique to verify whether Bacillus cereus isolated at different phases of UHT milk processing belongs to the same strain. For this, six groups of milk samples composed of raw, pasteurized and UHT milk were collected from a processing plant. The results revealed that bacteria belonging to the Bacillus cereus group were isolated from 51.6%, 81.6% and from 13.8% of raw, pasteurized and UHT milk samples, respectively. About 50.0% of isolates from raw milk, 19.2% isolates from pasteurized milk and 70.7% isolates from UHT milk were capable of...
