25. Influence of physical damage and freezing on histamine concentration and microbiological quality of yellowfin tuna during processing
Yellowfin tuna has a high level of free histidine in their muscle, which can lead to histamine formation by microorganisms if temperature abuse occurs during handling and further processing. The objective of this study was to measure levels of histamine in damaged and undamaged thawed muscle to determine the effect of physical damage on the microbial count a

26. Trends in bacterial resistance in a tertiary university hospital over one decade
The objective of this study was to investigate bacterial resistance trends, infection sites and the relationship between resistance and admittance to the intensive care unit (ICU). A total of 53,316 bacteria identified between 1999 and 2008 were evaluated. Multidrug resistance was characterized when gram-negative bacilli (GNB) presented resistance to two or

27. A specific polymerase chain reaction method to identify Stenotrophomonas maltophilia
Stenotrophomonas maltophilia is a multidrug-resistant nosocomial pathogen that is difficult to identify unequivocally using current methods. Accordingly, because the presence of this microorganism in a patient may directly determine the antimicrobial treatment, conventional polymerase chain reaction (PCR) and real-time PCR assays targeting 23S rRNA were dev

28. Non-biting flying insects as carriers of pathogenic bacteria in a Brazilian hospital
IntroductionInsects have been described as mechanical vectors of nosocomial infections.MethodsNon-biting flying insects were collected inside a pediatric ward and neonatal-intensive care unit (ICU) of a Brazilian tertiary hospital.ResultsMost (86.4%) of them were found to carry one or more species of bacteria on their external surfaces. The bacteria isolated

29. Factors influencing the early mortality in haematological malignancy patients with nosocomial Gram negative bacilli bacteraemia: a retrospective analysis of 154 cases
BACKGROUND: The aim of this study is to assess the factors influencing the early mortality (7- day after index blood culture) in haematological malignancy patients with Gram negative bacilli (GNB) bacteraemia. METHODS: Infection control committee records were reviewed to identify the cases between March 2006 and June 2011. Only one bacteraemic episode per pa

30. Successful use of gentamycin as an antibiotic prophylaxis regimen to reduce the rate of healthcare-associated infections after renal transplantation
At our institution, we observed an increase in the incidence of healthcare-associated infections (HAI) due to Gram-negative bacilli, including three cases of carbapenem-resistant Klebsiella pneumoniae, among patients who underwent renal transplantation. In addition to strengthening infection control measures, we chose to add gentamycin to the antibiotic prop

31. Antimicrobial use, incidence, etiology and resistance patterns in bacteria causing ventilator-associated pneumonia in a clinical-surgical intensive care unit
INTRODUCTION: Antimicrobial resistance is an increasing threat in hospitalized patients, and inappropriate empirical antimicrobial therapy is known to adversely affect outcomes in ventilator-associated pneumonia (VAP). The aim of this study was to evaluate antimicrobial usage, incidence, etiology, and antimicrobial resistance trends for prominent nosocomial

32. Bacteriological features of infectious spondylodiscitis at Mohammed V Military Teaching Hospital of Rabat
To review the bacteriological features of infectious spondylodiscitis and provide recommendations for the initial therapy which remains empirical in our context. Retrospective study including patients diagnosed with spondylodiscitis over a period of 4 years (2006-2009) at the Rabat Military Teaching Hospital. During the study period, we analysed 30 cases: th

33. Phenotypic and genotypic characterization of Rhodococcus equi isolated from sputum
INTRODUCTION: Rhodococcus equi is an opportunistic pathogen, causing rhodococcosis, a condition that can be confused with tuberculosis. Often, without identifying M. tuberculosis, physicians initiate empiric treatment for tuberculosis. R. equi and M. tuberculosis have different susceptibility to drugs. Identification of R. equi is based on a variety of pheno

34. Increasing antibiotic resistance among uropathogens isolated during years 2006-2009: impact on the empirical management
Urinary tract infections (UTI) are one of the most common infections with an increasing resistance to antimicrobial agents. PURPOSE: Empirical initial antibiotic treatment of UTI must rely on susceptible data from local studies. MATERIALS AND METHODS: Retrospective analysis of isolated bacteria from children with UTIs was performed at the university hospital

35. Gram-negative osteomyelitis: clinical and microbiological profile
INTRODUCTION: Despite the growing interest in the study of Gram-negative bacilli (GNB) infections, very little information on osteomyelitis caused by GNB is available in the medical literature. OBJECTIVES AND METHODS: To assess clinical and microbiological features of 101 cases of osteomyelitis caused by GNB alone, between January 2007 and January 2009, in a

36. Efeito da própolis sobre o crescimento de bacilos gramnegativos móveis coletados em hortifrutigranjeiro
Currently there is great concern about the quality and food contamination. All food marketed "in nature" may have some kind of contamination by microorganisms can be or not pathogenic for those who consume them. The contamination can occur throughout the production chain until it reaches the final consumer. In addition to the health problem, contamination ca
