Causative agents and resistance among hospital-acquired and ventilator-associated pneumonia patients at Srinagarind Hospital, northeastern Thailand.
Abstract. Hospital-acquired pneumonia (HAP) and ventilator-associated pneumonia (VAP) have an impact on health care costs and mortality. The aim of this study was to identify the causative agents, antibiotics prescribed, cost of treatment and drug resistance trends among HAP and VAP patients at a tertiary-care hospital in northeastern Thailand during 2008 and 2009. ⋯ Fifty-seven point six percent of P. aeruginosa isolates were sensitive to ceftazidime, 72.4% were sensitive to piperacillin/tazobactam, 95.9% were sensitive to netilmycin and 99.2% were sensitive to colistin. Forty-seven percent of K. pneumoniae isolates were extended spectrum beta-lactamase and sensitive to carbapenems. Methicillin-resistant S. aureus was the cause of 6-7% of HAP/VAP cases in our study.

Review Case ReportsListeria monocytogenes brain abscess: two cases and review of the literature.
Listeria monocytogenes is a gram-positive bacillus that exhibits predilection to infect the central nervous system in immunocompromised individuals; the most common manifestations are meningitis and rhombencephalitis. Listerial brain abscesses are rare. We report here two brain abscess cases caused by L. monocytogenes in patients receiving immunosuppressive agents. ⋯ Listerial DNA was detected in the pus aspirated from the abscess in the first case. Both patients were successfully treated with intravenous ampicillin followed by oral amoxicillin. MRS was useful in differentiating infectious processes from non-infectious causes.

Risk factors and clinical outcomes of extended spectrum beta-lactamase (ESBL)-producing Escherichia coli septicemia at Srinagarind University Hospital, Thailand.
Escherichia coli producing extended spectrum beta-lactamase (ESBL) has emerged as a worldwide, public health problem. The aims of this study were to determine the incidence of ESBL-producing E. coli septicemia and evaluate the factors associated with the infection and the clinical outcomes. We reviewed 145 cases of E. coli septicemia among adult patients admitted to Srinagarind University Hospital in northeastern Thailand between 2005 and 2006. ⋯ The overall mortality rate was significantly higher among the ESBL-producing E. coli septicemia group than the non-ESBL producing E. coli septicemia group (29% vs 11.5%, respectively, p = 0.02). A high APACHE II score, ESBL-producing E. coli septicemia, primary septicemia, and having a non-urinary tract infecting as a source of septicemia were significantly independent factors related to mortality among patients with E. coli septicemia. ESBL-producing E. coli septicemia is an important cause of nosocomial infection and is related to higher mortality risk, especially among those with primary septicemia and secondary septicemia due to a non-urinary tract infection.

Review Case ReportsEarly onset neonatal bacterial meningitis caused by Streptococcus gallolyticus subsp. paste urianus.
We report a case of neonatal meningitis due to Streptococcus gallolyticus subsp. pasteurianus born to a mother with an asymptomatic urinary tract infection due to Streptococcus group D and Escherichia coli. In the past, this organism may have been reported as Streptococcus bovis or S. bovis biotype II/2. Accurate identification of this organism is necessary to determine the etiology of infection and give correct treatment of neonatal meningitis, caused by this organism.
