Citrobacter, a Gram-negative enteric bacillus, is a rare cause of septicemia and meningitis, seldom reported beyond the neonatal period. It is characterized by a fulminant clinical course and a high incidence of complications, including brain abscesses. We studied a three-month-old infant with Citrobacter meningitis, who developed acute communicating hydrocephalus and multiple periventricular b...

A 45-year-old man with a cholesteatoma experienced purulent meningitis. Microbial analysis of cerebrospinal fluid yielded in pure culture a gram-negative bacillus. Phenotypic methods were suggestive of a Bacteroides distasonis or either a Bacteroides thetaiotaomicron or Bacteroides ovatus infection. The isolate was identified by 16S rRNA gene sequence analysis as B. thetaiotaomicron. This is th...

Flavobacterium meningosepticum is a gram negative, opportunistic organism which has been implicated in a number of outbreaks of sepsis and meningitis in newborn nurseries. The infection is usually associated with a very high mortality. F. meningosepticum is usually resistant to most of the commonly used antibiotics and successful therapy has posed problems. We present a case report of F. mening...

reports have emphasised the severity of neurological and systemic disorder in patients with toxocaral meningoencephalitis.1 2 " Apart from neck stiffness our patient was surprisingly well with no evidence of encephalitis. Her diagnosis might have been that of an atypical viral meningitis had Romanovsky staining not been performed. We think that this investigation may be useful in culture negati...

Background Bacterial meningitis still represents an important chapter in the present infectious pathology, despite the increasing progress in the prophylaxis and prevention measures. Apart from tuberculous etiology, and of course the well-known classical etiologies – meningococcal, pneumococcal, Haemophilus influenzae, staphylococcal and Gram-negative bacteria – new entities that need to be eva...

A glucose-negative group B strain of Neisseria meningitidis isolated from a meningitis case is described. A brief review of Neisseria identification procedures is also presented.

Two cases of Strongyloides stercoralis hyperinfestation syndrome accompanied by Gram negative bacteraemia and meningitis were studied. Both occurred in non-immunosuppressed West Indian women.

Yersinia enterocolitica, a gram negative aerobic non-haemolytic bacillus, has been identified as a cause of meningitis only once before and the neuropathological features of Y. enterocolitica meningitis have not been reported in the literature. We describe the pathological features of a case of acute fatal meningitis caused by Y. enterocolitica, serotype 0:18, in a 47-year-old male alcoholic wi...

Dengue infection is a mosquito-borne disease caused by a flavivirus, and is recognized in over 100 countries with 2.5 billion people living in areas of risk. Neurological manifestations such as encephalitis, myelitis, Guillain-Barré syndrome, cranial nerve palsies, neuromyelitis optica, and encephalomyelitis have been recognized as clinical consequences of dengue infection. Meningitis is a rare...

Meningitis caused by enteric flora is a known complication of strongyloidiasis, and human T-lymphotropic virus-1 (HTLV-1) predisposes individuals to severe strongyloidiasis. We reviewed the clinical features of bacterial meningitis associated with strongyloidiasis seen at a single center in subtropical Japan, in an area endemic for both strongyloidiasis and HTLV-1. We found 33 episodes in 21 pa...
