ABSTRACT
Objective To analyze characteristics of pathogenic microbiology and antimicrobial susceptibility of Vib-rio vulnificus (V.vulnificus)causing infection in patients at a hospital in Shantou City. Methods Four patients with V.vulnificus infection admitted to a hospital between June 2013 and June 2014 were analyzed retrospectively, blood specimens of patients were collected for culture,blister fluid and wound secretion were taken and inoculated on blood agar plates,MacConkey agar plates,and thiosulfate citrate bile salts sucrose (TCBS)plates,isolated strains were identified and performed antimicrobial susceptibility testing. Results Among 4 patients with V. vulnificus infection,3 died,1 was cured;patients developed primary septicemia and lower extremity infection be-cause of eating pickled crab,steamed scallop,or contacting with seafood products after trauma. Blister fluid from patients A and B,wound secretion from patient C,and blood from patient D were all isolated oxidase-positive gram-negative bacteria which produced green colonies on TCBS plate,these strains were identified as V.vulnificus, which were resistant or intermediate to cefazolin,intermediate to cefotetan,and 1 strain was resistant to cefepime. Conclusion Four patients infected with V.vulnificus have high mortality rate (3/4),positive rates of blister fluid and wound secretion are higher than blood;timely medical consultation,early antimicrobial therapy,and active de-bridement will help to cure the disease.
ABSTRACT
Os pombos domésticos e silvestres estão distribuídos por todo o mundo e carreiam micro-organismos patogênicos ao homem e a outros animais, podendo ser um dos responsáveis pela disseminação de Salmonella spp. Este patógeno gera grande preocupação para a economia mundial, uma vez que cria transtornos para a indústria avícola quando ocorre contaminação dos plantéis e ônus para a saúde pública devido a surtos de infecção alimentar causados por esta bactéria. Dessa forma, objetivou-se realizar um levantamento acerca da participação do pombo doméstico na possível disseminação de Salmonella spp.(AU)
Domestic and wild pigeons are distributed throughout the world and carrie micro-organisms that are pathogenic to humans and other animals. They can be one of the animals in charge of the dissemination of Salmonella spp., pathogen of great concern for the world economy as it creates inconvenience to the poultry industry when there is contamination of herds and impacts on public health due to outbreaks of foodborne infection caused by this bacterium. Therefore, the objective was to conduct a survey about the participation of the domestic pigeon in the possible dissemination of Salmonella spp.(AU)
