1. Fulminant citrobacter meningitis with multiple periventricular abscesses in a three-month-old infant
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 hydroce

2. Isolamento de enterobactérias em Alphitobius diaperinus e na cama de aviários no oeste do estado do Paraná, Brasil
O objetivo deste trabalho foi realizar o isolamento de bactérias da família Enterobacteriaceae em adultos de A. diaperinus, buscando uma correlação entre as bactérias presentes no inseto e na cama, em aviários para produção de frangos de corte no oeste do Paraná, Brasil. No primeiro experimento, insetos adultos foram coletados em 14 granjas. No segu

3. Abscesso cerebral por Citrobacter diversus na infância: relato de caso
Citrobacter diversus é a bactéria mais associada a abscessos cerebrais durante o período neonatal. Descrevemos um caso de abscesso cerebral por esta bactéria em um recém-nascido e sua evolução clínica e tomográfica até o quarto mês de vida. São discutidos aspectos diagnósticos e terapêuticos desta grave infecção do recém-nascido.

4. Recognition of Citrobacter diversus in the Clinical Laboratory
Characteristics and antibiotic sensitivities of Citrobacter diversus are described, and a minimal number of diagnostic tests to identify this organism in a clinical laboratory are suggested.

5. In vitro susceptibility of Citrobacter species to various antimicrobial agents.
The in vitro activities of 16 antimicrobial agents against 14 clinical isolates of Citrobacter diversus and 27 isolates of Citrobacter freundii were studied. C. freundii isolates were more resistant, being susceptible only to amikacin, netilmicin, gentamicin, imipenem, ciprofloxacin, and enoxacin. C. diversus isolates were susceptible to many more of the age

6. Rapid presumptive identification of Citrobacter diversus as an aid in controlling infections.
During an outbreak of neonatal meningitis caused by kanamycin-resistant Citrobacter diversus, a field procedure for presumptive identification of the organism was evaluated, and using it resulted in the early recognition of patients colonized by the epidemic strain of C. diversus. Rectal and nasopharyngeal specimens were plated and incubated on MacConkey aga

7. Molecular epidemiology of a nosocomial outbreak due to SHV-4-producing strains of Citrobacter diversus.
Over a 6-month period, eight strains of Citrobacter diversus (Citrobacter koseri) resistant to extended-spectrum cephalosporins and monobactams were isolated from seven colonized and/or infected patients from the same intensive care unit. All strains harbored a single large conjugative plasmid which mediated an extended-spectrum beta-lactamase of the SHV-4 t

8. Epidemiologic marker system for Citrobacter diversus using outer membrane protein profiles.
Investigations of nursery outbreaks of Citrobacter diversus sepsis and meningitis have been hampered by lack of adequate epidemiologic markers for the organism. We studied outer membrane protein profiles from clinical isolates of C. diversus by sodium dodecyl sulfate-polyacrylamide gel electrophoresis to determine whether this method might be useful in the e

10. Pathophysiology of Citrobacter diversus neonatal meningitis: comparative studies in an infant mouse model.
Citrobacter diversus is a cause of devastating neonatal meningitis, with illness characterized by formation of multiple brain abscesses. We developed an infant mouse intracranial inoculation model to evaluate the pathophysiology of C. diversus neonatal infections. Eighteen of 26 strains inoculated intracranially at a dose of ca. 3.3 x 10(3) CFU caused greate

11. Genotypic heterogeneity of strains of Citrobacter diversus expressing a 32-kilodalton outer membrane protein associated with neonatal meningitis.
Genetic diversity and relationships among 42 strains of Citrobacter diversus recovered from the cerebrospinal fluid of human infants with meningitis and from other clinical sources in the United States were estimated on the basis of electrophoretically detectable allelic variation in 20 genes encoding metabolic enzymes. Sixteen distinctive multilocus enzyme

12. Cloning and sequencing of a gene encoding an aminoglycoside 6'-N-acetyltransferase from an R factor of Citrobacter diversus.
The aacA1 gene, which encodes a 6'-N-acetyltransferase [AAC(6')-I] mediating resistance to kanamycin, tobramycin, and amikacin, was cloned from the Citrobacter diversus R plasmid pBWH100 into the Escherichia coli vector pBR322. The complete nucleotide sequence of the gene and flanking regions was determined. A protein of approximately 21 kilodaltons was iden
