265. Different ratios of the piperacillin-tazobactam combination for treatment of experimental meningitis due to Klebsiella pneumoniae producing the TEM-3 extended-spectrum beta-lactamase.
We evaluated the pharmacokinetics and therapeutic efficacies of piperacillin and tazobactam, a beta-lactamase inhibitor, given either alone or in different combinations (80:10, 200:10, and 80:25 mg/kg/h), in experimental meningitis due to a strain of Klebsiella pneumoniae producing the TEM-3 extended-spectrum beta-lactamase. Treatment was administered intrav

266. Indirect Sandwich Enzyme-Linked Immunosorbent Assay for Rapid Detection of Haemophilus influenzae Type b Infection
We report the development and testing of an enzyme-linked immunosorbent assay with excellent sensitivity for the detection of Haemophilus influenzae type b (HIb) antigen in clinical specimens from patients with HIb meningitis. The assay, an indirect sandwich technique, uses polystyrene balls as a solid phase and an alkaline phosphatase-labeled goat anti-rabb

267. Comparison of Conventional Bacteriology with Nucleic Acid Amplification (Amplified Mycobacterium Direct Test) for Diagnosis of Tuberculous Meningitis before and after Inception of Antituberculosis Chemotherapy
The role of nucleic acid amplification techniques in the rapid diagnosis of tuberculous meningitis remains uncertain. We compared the performance of Ziehl-Neelsen (ZN) staining, the Gen-Probe amplified Mycobacterium tuberculosis direct test (MTD), and culture with 341 cerebrospinal fluid specimens from 152 adults (73 with and 79 without tuberculous meningiti

268. The Capsule Supports Survival but Not Traversal of Escherichia coli K1 across the Blood-Brain Barrier
The vast majority of cases of gram-negative meningitis in neonates are caused by K1-encapsulated Escherichia coli. The role of the K1 capsule in the pathogenesis of E. coli meningitis was examined with an in vivo model of experimental hematogenous E. coli K1 meningitis and an in vitro model of the blood-brain barrier. Bacteremia was induced in neonatal rats

269. Production and evaluation of autogenous bacterin against streptococcal meningitis in swine / Produção e avaliação de bacterina autógena contra meningite estreptococcica em suínos
The present work was developed with the objective to determine the efficiency of an autogenous bacterin against Streptococcus suis serotype 2 and to test route and inoculation doses. Two experiments were accomplished with 64 animals in each experiment. In the Experiment I, 32 animals were vaccinated and 32 animals received placebo, being both groups challeng

270. Papel da colonoscopia com magnificação de imagem associada à cromoscopia no diagnóstico diferencial entre lesões neoplásicas e não-neoplásicas do intestino grosso / Course of neonatal bacterial meningitis according to birth weight
O Câncer colorretal (CCR) é um problema de saúde importante devido a sua incidência e mortalidade elevadas. O rastreamento e o diagnóstico precoce são a principal estratégia para diminuir a mortalidade pelo CCR. A colonoscopia convencional (CC), constitui o melhor método para o diagnóstico precoce do CCR e para o diagnóstico e tratamento das lesõe

271. Perfil epidemiológico da doença meningocócica, no estado de Minas Gerais, entre 2000 e 2009. / Epidemiological profile of meningococcal disease, in the state of Minas Gerais, from 2000 to 2009.
The infection by Neisseria meningitis, named meningococcal disease (MD), can cause meningococcal meningitis and septicemia with or without meningitis. MD is an endemic disease in Brazil, however, has a high potential to cause epidemics and high case fatality which require immediate notification of the cases. The aims of this study were to describe an epidemi

272. Hemin utilization is related to virulence of Streptococcus pneumoniae.
Streptococcus pneumoniae is a causative agent for bacterial pneumonia, otitis media, meningitis, and bacteremia. Mechanisms for acquisition of iron by this organism under low-iron conditions were investigated. Siderophore production was not detected by either chemical or biological methods. Its utilization of iron-containing compounds found in human hosts wa

273. Fatal Strongyloides stercoralis hyper-infection in a patient with multiple myeloma
Strongyloides stercoralis (S.S.) is a human intestinal parasite, which may lead to complicated strongyloidiasis. We report a case of disseminated strongyloidiasis following the treatment of myeloma. The patient developed skin lesions, respiratory distress, aseptic meningitis and bacterial and fungal sepsis. The diagnosis of strongyloidiasis was established t

274. Amikacin in Newborn Infants: Comparative Pharmacology with Kanamycin and Clinical Efficacy in 45 Neonates with Bacterial Diseases
The pharmacokinetic properties of amikacin (BBK8) were similar to those of kanamycin in newborn infants. Peak serum concentrations of both drugs were in the range of 15 to 25 μg/ml with the exception of kanamycin in babies weighing greater than 2,000 g at birth where peak levels were 12.5 to 15 μg/ml. Volumes of distribution, plasma clearances, and serum h

275. Opsonin System of the Group B Streptococcus
The opsonization by polymorphonuclear leukocytes of group B streptococcal serotypes associated with neonatal sepsis and delayed meningitis was studied. A specific BIa opsonizing antibody (not related to the antipolysaccharide typing antibody) was present in only 10% of the population tested. Serotype BIa was not opsonized in the absence of this specific anti

276. Antimicrobial resistance patterns of Haemophilus influenzae isolated from patients with meningitis in São Paulo, Brazil
From 1989 to 1995, a total of 391 Haemophilus influenzae isolates were recovered from the cerebrospinal fluid (CSF) of hospitalized patients in São Paulo, Brazil. The majority of strains were isolated from infants aged less than 5 years. Strains belonging to biotype I (64.7%), biotype II (34.5%) and biotype IV (0.76%) were detected. Ninety-nine percent of t
