Hepatitis B Virus preS1-antigen HBV-DNA,and HBV Markers in Patients with Hepatitis B:Correlation Studies / 中华医院感染学杂志

OBJECTIVE To investigate the correlations on hepatitis B virus(HBV)preS1-antigen(preS1-Ag)and HBV-DNA,HBV markers in patients with hepatitis B.METHODS The markers,preS1-Ag and HBV-DNA were determined by ELISA and PCR in 406 patients with hepatitis B and 80 healthy persons.RESULTS The positive rates of preS1-Ag in 160 patients with HBsAg(+)and HBeAg(+)were 84.4%.The positive rates of preS1-Ag in 246 patients with HBsAg(+)and HBeAg(-)were 42.3%;the difference between them was significant(?2=70.9,P

Pathogens Causing Chronic Prostatitis and Their Distribution and Resistance / 中华医院感染学杂志

0.05).(3) The ratio of meticillin-resistant staphylococci was 91.5%.The ratio of resistance of staphylococci to(gentamicin),(erythromycin),ciprofloxacin and tetracycline was all above 50%,but was low to(nitrofurantoin) and rifampin.In 12 strains of Enterococcus faecalis,3 strains were VRE;8 resisted to high-level gentamicin;6 resisted to high-level streptomycin;the resistance rate to tetracycline,ciprofloxacin,rifampin and(erythromycin) ranged from 58.3% to 100.0%.In E.coli,8 of 14 isolates were positive for ESBLs.The resistance was high to usual antibiotics except imipenem,amikacin and Tazocillin.CONCLUSIONS Bacteria are the main pathogens of chronic prostatitis and terribly resist to clinical usual antibiotics.Infection with Uu,Mh and Ct should not be(ignored).It is necessary to diagnose and treat chronic prostatitis according to the results of pathogen(isolation) and drug sensitivity test.

Culturing of Urogenital Tract Mycoplasma and Its Susceptibility to Antibiotics:Analysis of 336 Cases in Zhoushan Islands / 中华医院感染学杂志

OBJECTIVE To explore the pathogenesis of Ureaplasma urealyticum(Uu)and Mycoplasma hominis(Mh)in urogenital tract infection and their susceptibility to antibiotics.METHODS Mycoplasma culture was carried out with the samples of 336 cases and then the susceptibility to 9 kinds of antibiotics was detected on positive samples.RESULTS From 336 cases 177 were infected with mycoplasma,the total positive rate was 52.7%,the positive rates of Uu,Mh and their mixed infection were 40.5%,2.4% and 9.8%,respectively.The positive rate of female was higher than of male(P

Distribution Characteristics and Antimicrobial Resistance of Acinetobacter baumannii Infection:An Investigation of 194 Cases in Zhoushan Islands / 中华医院感染学杂志

OBJECTIVE To study the isolation rate,distribution characteristics and antimicrobial resistance of Acinetobacter baumannii infection.METHODS Surveillance data of A.baumannii infection,distribution and resistance rates to 12 kinds of antibiotics in our hospital for 3 years were analyzed.RESULTS During the 3-year infection surveillance,194 strains of A.baumannii were isolated in our hospital.The isolation rate was 7.8% in 2006,though 2.4% in 2004.Eighty strains(41.2%) of A.baumannii were from intensive care unit;95 strains were from over 60-year-old sufferers;compared with 2004 and 2005,the resistance rates of A.baumannii in 2006 to 12 kinds of antibiotics were increasing at different degree.The antibacterial susceptibility to imipenem/meropenem was the highest.CONCLUSIONS The isolation rate of A.baumannii and antimicrobial resistance rate are increasing year by year.The A.baumannii strains shows obvious multiple antibacterial resistance.We must keep monitoring of A.baumannii infection and drug-resistant changes in order to prevent nosocomial infections.
