Non-O:1 Vibrio cholerae infections present clinically mainly as gastroenteritis (67%), septicemia (15%) or wound infection (8%) [1]. Seafood consumption is very common in the week preceding the onset of symptoms [1], but nosocomial infection may also occur [2]. Non-O:1 Vibrio cholerae septicemia is rare, particularly in the paediatric age group [1]. Eight cases of septicemia in children infected with this microorganism have been reported previously in the English-language literature [2,3,4,5,6,7,8,9], and three of them had meningitis as well [4,5,6] (1 had hydrocephalus, 1 had cerebral abscess-like lesions and 1 died). Reported here is an additional case of an infant who developed non-O:1 Vibrio cholerae septicemia with meningitis, cerebral abscess and unilateral hydrocephalus.The infant, male patient was born at 33 weeks gestation to a primigravida after an uneventful pregnancy and delivery, with a birth weight of 2.2 kg. The baby fed well and was discharged at the age of 24 h. At 60 h of age he was admitted to hospital with a 24-h history of poor feeding and recurrent, brief episodes of central and peripheral cyanosis in the preceding 1 h. Vomiting and diarrhea were absent. His weight was 2.01 kg, head circumference 29.5 cm, length 42 cm (all <50 th percentile), heart rate 140/min, respiratory rate 40/min, and temperature 36.3°C. He was observed to be sucking poorly and was hypotonic. The anterior fontanel was normal, and the physical examination was otherwise unremarkable. Blood and urine cultures were collected before ampicillin and cefotaxime were given intravenously (each in a dose of 200 mg/kg/day in 4 divided doses). Twelve hours later the patient had a generalized tonic-clonic convulsion. Intravenous phenobarbitone was instituted and a noncontrast cerebral computerized tomogram (CT) revealed a haematoma in the left frontal lobe with normalsized ventricles.Examination of the cerebrospinal fluid (CSF) revealed the following: total leukocyte count, 1,170/mm 3 (68% polymorphs, 32% lymphocytes); erythrocyte count, 12,150/mm 3 ; glucose level, 70 mg/dl (concomitant serum glucose, 106 mg/dl); protein level, 1,206 mg/dl. The latex agglutination test was negative for Escherichia coli, group B Streptococcus, Streptococcus pneumoniae, Neisseria meningitidis and Haemophilus influenzae. Other investigations revealed the following: a total leukocyte count of 3,000/mm 3 (neutrophils, 40%; lymphocytes, 27%; monocytes, 23%); hemoglobin, 17.7 gm/dl; platelets, 241,000/mm 3 ; erythrocyte sedimentation rate, 2 mm/h; C-reactive protein, 19.5 mg/l (normal range, <8 mg/l); and total serum bilirubin, 11.7 mg/dl (direct 1). Liver and renal biochemical profiles remained normal. Blood culture grew oxidase-positive, gram-negative rods, which were identified biochemically as Vibrio cholerae and serologically as non-O:1 Vibrio cholerae (Central Microbiology Laboratory, Kuwait Ministry of Health). The organism was sensitive to ampicillin, cefotaxime and most of the other major antibiotics. The CSF, stool and urine cultures revealed no...
