Molecular epidemiology of bla -producing carbapenem-resistant Acinetobacter baumannii in a single institution over a 65-month period in north China.

Background: Carbapenem-resistant Acinetobacter baumannii poses a significant threat to hospitalized patients, as few therapeutic options remain. Thus, we investigated the molecular epidemiology and mechanism of resistance of carbapenem-resistant A.baumannii isolates in Beijing, China.

[Distribution of genotypes in ESBLs producing E. coli strains isolated from posthepatitic cirrhosis' patients with bloodstream infection].

Objective: To study the genotype distribution of extended-spectrum beta-lactamases (ESBLs) in ESBLs-producing Escherichia coli (E. coli) isolates from posthepatitic cirrhosis' patients with bloodstream infection.

Methods: E.

[The distribution and antimicrobial resistance tendency of pathogens associated with diarrhea in Beijing].

Objective: To monitor the constituents and resistant tendency of bacterial pathogens isolated from diarrheal patients in our hospital form 1994 to 2005 to offer the basis for guiding epidemiologic study, vaccination research and clinical treatment.

Methods: Enteric pathogenic bacteria were cultured and identified to species, group and serotype with biochemical and serologic methods and the susceptibility of bacteria to antimicrobial agents were tested.

Results: Enteric pathogenic bacteria were isolated predominantly in male patients and mainly in children and youngsters.

[Detection of multiresistance Aeromonas with TEM type resistant genes in patients with cirrhosis].

Objective: To study the status of beta-lactamase produced by multiresistant Aeromonas selected from cirrhosis patients to provide reference for treatment and reduce resistance and control spreading.

Methods: Four multiresistant Aeromonas strains isolated from serious liver cirrhosis patients from the No. 302 hospital.

[The clinical features and prognosis of Aeromonas septicaemia in hepatic cirrhosis: a report of 50 cases].

Objective: Aeromonas septicaemia complicating cirrhosis is not a common infectious disease. To enhance the knowledge in this aspect, we analysed the clinical features, pathogenetic factors, resistance, treatment and prognosis of Aeromonas septicaemia in 50 cases of hepatic cirrhosis.

Methods: We cultured the bacteria from infected patients with BacT/Alert120 automation instrument made in AKsu and identified the bacteria with the Vitek-AMS60 made in Biomerieux company.
