| An outbreak of staphylococcal food poisoning involving 42 people who had eaten a meal at a restaurant in the Municipality of Passos, Minas Gerais, Brazil, is reported. Thirty-one of the individuals became ill with vomiting, diarrhea and dizziness within 30 minutes after eating the meal. The foods suspected were: chicken pancake, rice, beans, tomato sauce and mashed chick-peas. Large numbers (> 2.0x10(8) CFU/g) of enterotoxigenic staphylococci were present in the chicken pancake. These strains produced enterotoxins A, B and D. Swabs from the nasal cavity and throat and from under the fingernails of food handlers were cultured for the detection of enterotoxigenic staphylococci carriers. Four out of five of them were healthy carriers of enterotoxin A, B, C... |

| Bacteria that attach to surface aggregate in a hydrated polymeric matrix of their own synthesis to form biofilms. These represent microbial societies with their own defense and communication system. Transitioning from acute to chronic infection is frequently associated with biofilm formation.Bacteria in biofilms are innately more resistant to antimicrobial agents. The presence of indwelling medical devices increases the risk for biofilm formation and subsequent infection. The current antibiotic therapies are of limited effectiveness in resolving biofilms infection.This review attempts to discuss the stages in biofilm formation, their pathogenic mechanisms, effect of antimicrobial agents, detection and eradication of the biofilms. |

| This study was conducted to determine the species distribution, antimicrobial resistance pheno- and genotypes and virulence traits of mannitol-positive methicillin-resistant staphylococci (MRS) isolated from pigs in Nsukka agricultural zone, Nigeria. Twenty mannitol-positive methicillin-resistant coagulase-negative staphylococcal (MRCoNS) strains harboring the mecA gene were detected among the 64 Staphylococcus isolates from 291 pigs. A total of 4 species were identified among the MRCoNS isolates, namely, Staphylococcus sciuri (10 strains), Staphylococcus lentus (6 strains), Staphylococcus cohnii (3 strains) and Staphylococcus haemolyticus (one strain). All MRCoNS isolates were multidrug-resistant. In addition to β-lactams, the strains were resistant to... |

| This study evaluated the middle ear microbiota and antimicrobial susceptibility patterns from strains isolated from dogs with otitis media. A total of 62 dogs obtained from Zoonoses Control Center of Fortaleza City Ceará State / Brazil were studied over a 10-month period (August/2003 to June/2004). Of the total, 46.8% (n=30) of the animals were positive for otitis media and the infection was monomicrobial in 76.6% of them. The most frequent isolated agents were coagulase-positive Staphylococci (CPS-55%) and Pseudomonas sp (10%). For S. intermedius (n=13) and S. aureus subsp aureus (n=9), respectively, the greater resistance rates were observed using penicillin G (30.76% and 44.44%), ampicillin (7.69% and 44.44%), erythromycin (23.07% and 44.44%),... |

| Swab samples obtained from 96 dogs with chronic otitis externa were cultured for the isolation of Staphylococcus species. Of 57 staphylococcal strains, 41 (72%) were coagulase-negative (CNS). The identification of staphylococci strains was made by standard procedures for the routine identification of staphylococci in clinical practice. S. sciuri was the most frequent species isolated (22.8%) from chronic otitis externa in dogs followed by S. intermedius (12.3%), S. auricularis (10.5%) and S. aureus (8.8%). Three (5.2%) CNS strains could not be identified. Bacterial isolates were susceptible to enrofloxacin, gentamicin, cephalothin, chloramphenicol and neomycin. Resistance was most common to penicillin G, oxacillin and ampicillin. |

| Subclinical mastitis in goats causes economic losses and risks to public health. Given the need for research that shows the most isolated staphylococci species and sensibility tests comparing the resistance between coagulase-negative (CNS) and positive Staphylococcus (CPS) goats with subclinical mastitis, the aim of this study was to identify the microorganisms isolated from milk samples of goats with subclinical mastitis, as well as define the staphylococci species and determine the sensitivity profile of Staphylococcus spp. to antimicrobials. To collect samples, tests were performed for mug of black background and California mastitis test (CMT), collecting milk from CMT positive animals. A total of 226 samples from seven herds of dairy goats was... |

| 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... |
