Item Acesso aberto (Open Access) Aspectos microbiológicos e epidemiológicos da doença diarréica aguda no município de Juruti, Pará(Universidade Federal do Pará, 2010-12-20) SOUSA, Eveline Bezerra; LOUREIRO, Edvaldo Carlos Brito; http://lattes.cnpq.br/2685418720563351The presente study described the epidemiological and etiological aspects of acute diarrhea in Juruti, Pará, Brazil. A total of 261 fecal samples were investigated (diarrheagenic, n = 170 and control, n = 91), from patients attended in Public Health Units in the period from February to July 2009. Samples were investigated for bacterial, Rotavírus and parasitic enteropathogens using microscopic examination, immunological tests (ELISA) and bacterial culture techniques. Two multiplex PCR were designed for the detection of all categories of diarrheagenic Escherichia coli. A total of 154 samples were positive (diarrheagenic, n = 118 and control, n = 36), in which 75,4% were represented for mono infections and 24,6% for mixed infections. Most of cases included children less than 10 years of age (55,9%), which no significant difference were found between female and male. The most common enteropathogens in diarrhoeal samples were E. histolytica/E. dispar (26%), Shigella spp (15,7%), Giardia lamblia (13,3%) and diarrheagenic E. coli (12,8%), from which Shigella spp (p = 0,0028) were shown to be associated to the cases of acute diarrhea. The most frequent categories of E. coli in diarrhoeal cases were ETEC (7,2%) and EAEC (5,9%). The less frequent enteropathogens, in diarrhoeal samples were Campylobacter jejuni/coli (4,7%), Rotavírus (2,8%), Salmonella Panama, A. hydrophila and A. sóbria (0,5%). These results are useful for environmental and epidemiological surveillance of acute diarrhea disease in Juruti.Item Acesso aberto (Open Access) ICB/PPGBAIP Estudo da ocorrência e perfil de suscetibilidade aos antimicrobianos de Staphylococcus aureus isolados de pacientes e profissionais de saúde na Unidade de Terapia Intensiva de hospital público de Rio Branco-AC(Universidade Federal do Pará, 2011-02-07) LAVIOLA GARCÊZ, Poliana Torres; LOUREIRO, Edvaldo Carlos Brito; http://lattes.cnpq.br/2685418720563351The nosocomial infection is a serious public health problem worldwide, mainly in patients admitted to the Intensive Care Unit, which are subject to greater risk due to the severity of clinical symptoms, constant use of broad spectrum antibiotics and frequency of use of invasive procedures. Staphylococcus aureus is a major pathogen that colonizes healthy individuals and is also responsible for infections in hospitalized patients. This study aimed to identify the resistance profile, main sites affected by infection and possible risk factors associated with infection or colonization by S. aureus isolated from patients and healthcare professionals from the Intensive Care Unit of Hospital Emergency and Emergency, Rio Branco (HUERB) – Acre. We developed a cross-sectional study, conducted between January to August 2009. To search for carriers, biological samples were collected from microbiota of patients and professionals and professionals hand washing. For a survey of cases of patients with nosocomial infection were collected biological samples from sites suspected of being affected, 72 hours from the date of admission until discharge, transfer or death. Of the 62 patients enrolled in the study, 19.3% were carriers and 6.4% developed nosocomial infections by S. aureus, and 35 professionals, 28.6% were carriers of S. aureus. It was the second most bacterial species isolated from patients, and was the fifth most isolated from cases of nosocomial infection. There was no statistical evidence for the variable state of coma, use of invasive procedures and state of carrier patient are considered risk factors for acquiring nosocomial S. aureus in this study. The anatomical sites affected by IH by S. aureus were the respiratory tract ( n=2), followed by blood (n=1). The sample catheter tip was responsible for one insulated. One (1.6%) patient developed IH by MRSA, and 5 (8,1%) patients and 2 ( 5.7%) professionals were MRSA carriers, low occurrence as it relates to the results of the rest of Brazil and world. We also emphasize the incidence of MRSA over MSSA and low antomicrobial resistance of MRSA demonstrating that the UTI-HUERB, the IH S. aureus does not constitute a public health problem. There were no isolates of S. aureus resistant to vancomicina, wich can be considered a therapeutic option for cases of IH by MRSA. It is worth emphasizing the importance of this study in Acre State, for being the first of its kind in the UTI, involving S. aureus and MRSA.
