molecular characterization and antimicrobial susceptibility of acinetobacter baumannii isolates obtained from two hospital outbreaks in los angeles county, california, usa.	antibiotic resistant strains of acinetobacter baumannii have been responsible for an increasing number of nosocomial infections including bacteremia and ventilator-associated pneumonia. in this study, we analyzed 38 isolates of a. baumannii obtained from two hospital outbreaks in los angeles county for the molecular epidemiology, antimicrobial susceptibility and resistance determinants.	2016	27146090
molecular epidemiology and characterization of multiple drug-resistant (mdr) clinical isolates of acinetobacter baumannii.	the aim of this study was to identify the genetic relatedness of multiple drug-resistant (mdr) acinetobacter baumannii clinical isolates recovered from a hospital in los angeles.	2015	26518066
herpes simplex activation prolongs recovery from severe burn injury and increases bacterial infection risk.	recovery from severe burn injury is complicated by infections that are result of immune suppression created by massive inflammatory states. one indication of immune suppression may be activation of viruses like herpes simplex virus (hsv), which may negatively impact recovery. a 5-year retrospective review was performed of adult patients with ≥30% tbsa burn injury. tbsa burn injury, length of hospital stay, ventilator days, mortality, and cultures were reviewed. twenty-one patients had cutaneous ...	2011	22079915
molecular epidemiology of carbapenem-nonsusceptible acinetobacter baumannii in the united states.	acinetobacter baumannii is emerging as an important nosocomial pathogen worldwide. we report molecular epidemiology of 65 carbapenem-nonsusceptible a. baumannii isolates identified from hospitals in new york, pennsylvania, florida, missouri, nevada, and california between 2008 and 2009. all isolates were subjected to pulsed-field gel electrophoresis (pfge). select isolates then underwent multilocus sequence typing (mlst). while the pfge patterns tended to cluster within each hospital, sequence t ...	2011	21918019
phenotypic and molecular characterization of acinetobacter baumannii clinical isolates from nosocomial outbreaks in los angeles county, california.	multidrug-resistant acinetobacter baumannii strains have increasingly resulted in nosocomial outbreaks worldwide, leaving limited options for treatment. to date, little has been reported on the antimicrobial susceptibilities and genomic profiles of a. baumannii strains from hospital outbreaks in the greater los angeles area. in this study, we examined the susceptibilities and genetic profiles of 20 nonduplicate isolates of a. baumannii from nosocomial outbreaks in los angeles county (lac) and de ...	2008	18524965
prevalences of zoonotic bacteria among seabirds in rehabilitation centers along the pacific coast of california and washington, usa.	many seabirds are rehabilitated annually by wildlife rehabilitation centers along the pacific coast, usa. although various strains of zoonotic bacteria have been isolated from seabirds, risks to rehabilitators at these centers have not been well documented. from november 2001 through january 2003, we determined the prevalence of detectable enteric fauna by isolation and characterization of gram-negative bacteria from cloacal swabs taken from 26 common murres (uria aalge), 49 gulls (larus spp.), ...	2005	16456162
low-level colonization and infection with ciprofloxacin-resistant gram-negative bacilli in a skilled nursing facility.	we report a 1-year surveillance study that evaluates colonization and infection with ciprofloxacin-resistant gram-negative bacilli (cr gnb) and the relation to quinolone use and other possible risk factors in a proprietary skilled nursing facility (snf) with no history of outbreaks.	1998	9836837
