Extended Spectrum

Extended-spectrum β-lactamase (ESBL)–producing Escherichia coli strains have been reported worldwide; however, the incidence and characterization of foodborne ESBL-producing E. coli strains have been rarely reported in the People's Republic of China. Among a collection of 659 E. coli isolates recovered from retail foods in Shaanxi Province, People's Republic of China, 223 cefoxitin-resistant and/or cefoperazone-resistant isolates were screened for ESBL production with the double disk diffusion test. The ESBL-producing isolates were characterized for antimicrobial resistance and the presence of blaTEM, blaSHV, and blaCTX-M genes. Isolates with blaCTX-M were further classified by PCR as having blaCTX-M-1, blaCTX-M-2, blaCTX-M-8, blaCTX-M-9, or blaCTX-M-25. One hundred forty-seven isolates were identified as ESBL positive. PCR detection revealed that 146 isolates (99.3%) contained the blaCTX-M gene. Among these isolates, 42 (28.8%) were positive for the enzyme CTX-M-1, 5 (3.4%) for CTX-M-2, and 99 (67.8%) for CTX-M-9. No CTX-M-8 and CTX-M-25 were found in this study. One hundred fifteen isolates (78.2%) were positive for the blaTEM gene, but blaSHV was not detected. Among the 147 ESBL-producing E. coli isolates, 75 (51.0%), 35 (23.8%), and 4 (2.7%) isolates were positive for blaTEM and blaCTX-M-9, blaTEM and blaCTX-M-1, and blaTEM and blaCTX-M-2, respectively. All of the 147 ESBL-producing isolates were resistant to three or more non–β-lactam antibiotics. This study provides evidence that foodborne E. coli can harbor ESBL-encoding genes. Thus, food could be a vehicle for the dissemination of ESBL-producing E. coli strains, a situation that requires surveillance and appropriate management strategies.

Stool Specimens

Human astrovirus (HAstV) was an important cause of viral gastroenteritis in infants in Wuhan city based on our previous study. The aim of the study was to investigate the nature of HAstV infection in Wuhan, People’s Republic of China, especially in adults. Stool specimens were collected from 361 children and 301 adults with diarrhea from July 2007 to June 2008 and were tested for HAstV RNA by RT-PCR. The 348-bp PCR product of positive samples was further sequenced and analyzed for multiple sequence alignment and phylogenetic tree. HAstV RNA was detected in 2.33% (7/301) adults, which was significantly lower than that in children (13.57%, 49/361). HAstV-positive patients were either older than 50 years of age or younger than 3. Genetic analysis showed that the HAstV strain in adults was the same as that in children in 2007–2008. Contrarily, HAstV strains prevalent in 2007–2008 showed genetic characteristics different from those in 2004–2005 and belonged to two new groups of HAstV-1b. Thus, our data characterized HAstV infection in Wuhan 2007–2008, suggesting that HAstV infection also played an important role in adults in Wuhan, especial in patients of >50 years, and should be included for routine diagnosis in the population with diarrheal illness.
