ABSTRACT
Objective To analyze the identification and antibiotic resistance of non active Escherichia coli isolated from feces . Methods Clinical fecal specimens were collected from January 2013 to June 2015 for bacterial culture ,identification and antimicro-bial susceptibility testing .Results Sixty-one strains of E .coli ,inactive were detected ,18 strains of which could be agglutinated with diagnostic serum of Shigella .Three stains could produce extented spectrum β-lactamases(ESBLs);The rate of antibiotic resistance of amoxicillin and ticarcillin was 100% ,The rate of piperacillin ,cephalothin and sulfamethoxazole was 78% ,the rate of cefoxitin and amikacin was 33% ,the rate of piperacillin/tazobactam ,imipenem and meropenem was 0% .Conclusion Non active Escherichia coli can induce diarrhea ,which is easily misdiagnosed as Shigella ,the antimicrobial resistance between Escherichia coli and non active Escherichia coli is not significant difference .
ABSTRACT
Objective To evaluate the clinical value of white blood cell(WBC) ,neutrophilic granulocyte percentage(NEUT% ) and C‐reactive protein(CRP) in lung infection of early chronic obstructive pulmonary disease(COPD) ,and analyse the pathogen dis‐tribution .Methods 186 cases of hospitalized patients with COPD were enrolled as research group and 60 healthy ones as control group .Compared WBC ,NEUT% ,CRP levels between the two groups .According to sputum culture results ,patients were divided into normal flora group and pathogen growth group;according to the type of pathogen ,patients were divided into G+ and G- group . Analyse WBC and CRP levels in each groups and compare sensitivity ,specificity and positive predictive value of the two indicators . Distribution of positive sputum culture results were statistically analyzed .Results The levels of three indicators in research group were higher than those in control group(P0 .05) .Based on sputum culture positive results ,the number of fungi is 86 ,and Candida albicans were the most accounting for 35 .85% .The number of bacteria were 73 strains .Differences in WBC ,NEUT% and CRP between G+ group and G- group were not significant(P> 0 .05) .Conclusion WBC ,NEUT% and CRP levels in COPD patients were higher than those in healthy group .But due to many factors which could affect the levels of WBC ,NEUT% and serum CRP ,a preliminary diag‐nosis of COPD lung infection can′t be made just through the three indicators .
