In order to study the effects of septic embolism on the brain, silicone rubber emboli of various types were injected into the carotid arteries of 35 dogs. Pathologic and angiographic studies were performed to assess the resultant arterial and parenchymal lesions. Pure silicone rubber emboli (14 dogs) produced occasional intra-arterial thrombosis but no arteritis. Sterile and bacterially contami...

We report a severe case of Capnocytophaga carnimorsus infection in an elderly male presented to regional hospital NSW. A 63-year-old patient emergency department unconscious state. On admission he was febrile, hypotensive, had multiple haemorrhagic and gangrenous lesions lactate 17 mmol/L. He clinically diagnosed as having septic shock meningitis/encephalitis. Blood cultures flagged positive wi...

Citrobacter koseri is a gram-negative bacillius that belongs to the Enterobacteriaceae family. It is an uncommon pathogen that typically causes meningitis and brain abscesses in children, however central nervous system (CNS) infections are rarely found in adults. We present a case of C. koseri meningitis in an immunocompetent adult secondary to intestinal micro-perforation caused by Strongyloid...

INTRODUCTION Normocellular bacterial meningitis is rarely observed in adult patients. We here report two cases of adult patients with pneumococcal meningitis with a normal cerebrospinal fluid leukocyte count and review eight other cases in the literature. CASE PRESENTATION Case 1 was a 34-year-old Japanese woman with a history of splenectomy who presented with pyrexia, nausea, headache, and l...

Introduction.Moraxella nonliquefaciens is an unusual organism to be isolated from cerebral spinal fluid (CSF) and there exists only one case report of M. nonliquefaciens meningitis from a neonate. Moraxella species normally exist as part of the human upper respiratory tract flora and rarely cause invasive human disease. There are only a handful of case reports implicating the organism as a caus...

M since described first in the year 1805, has been one of the major lethal infectious diseases especially for the neonates and elderly in developing countries.1 It is not always possible to distinguish between bacterial and viral meningitis according to CSF findings, which leads to unnecessary antibiotic usage.2 During the last few years, procalcitonin (PCT) has been a new parameter in the diag...

Background: Meningitis is the most common intracranial complication of sinusitis. Objective: Determine the frequency of sinusitis using CT scans in children with documented meningitis. Methods and materials: A prospective, cross sectional study was done in pediatric infectious ward of Rasul Hospital in Tehran, Iran during 2010-2011. In this study 65 cases with meningitis were evaluated for pres...

Abstract Background Aerococcus species are Gram-positive cocci, with negative catalase and oxidase activities growth characteristics similar to viridans streptococci. They rarely cause infection in humans. However, there reports of bacteremia, meningitis, septic arthritis, endocarditis due this pathogen the literature. Herein we report a rare case pyelonephritis A. viridans. Case presentation A...

OBJECTIVES   To determine the prevalence of bacteria in the cerebrospinal fluid (CSF), and the antibiogram profile in pediatric patients with suspected meningitis. Methods: This descriptive study was conducted between January 2014 and January 2016 in the Hevi Paediatric Teaching Hospital in Duhok, Iraq. The CSF samples were withdrawn from 432 pediatric patients suspected of meningitis. The samp...

INTRODUCTION Macrophage migration inhibitory factor (MIF) plays an essential pathophysiological role in septic shock, but its role in central nervous system infection (CNS) remains to be defined. METHODS We investigated cerebrospinal fluid (CSF) levels of MIF in 171 patients who were clinically suspected of having meningitis on admission. Of these, 31 were found to have purulent meningitis of...
