Common findings of bla CTX-M-55-encoding 104-139 kbp plasmids harbored by extended-spectrum ß-lactamase-producing Escherichia coli in pork meat, wholesale market workers, and patients with urinary tract infection in Vietnam.

Extended-spectrum, ß-lactamase-producing Escherichia coli (ESBL-E) harboring the bla CTX-M-55-encoding plasmid (ESBL-E55) has been reported to be associated with urinary tract infection (UTI). The aims of this study were to clarify the prevalence of ESBL-E55 in pork meats and workers from the same wholesale market, as well as patients with UTI from a nearby hospital in Vietnam; we also investigated the plasmids encoding bla CTX-M-55. Sequencing analysis showed that 66.6% of the ESBL-E isolated from pork meats contained bla CTX-M-55, whereas the gene was present in 25.0% of workers and 12.5% of patients with UTI. Plasmid analysis showed that several sizes of plasmid encoded bla CTX-M-55 in ESBL-E55 isolated from pork meats, whereas ESBL-E55 isolated from workers and patients with UTI contained only 104-139 kbp of bla CTX-M-55-encoding plasmids. This indicates that the 104-139 kbp sizes of bla CTX-M-55-encoding plasmids were commonly disseminated in pork meats, wholesale market workers, and patients with UTI.

[Risk of hepatitis C related to traditional medicine: a case control study in Ho Chi Minh City, Vietnam]. / Risque d'hépatite C lié à des pratiques traditionnelles: une étude cas témoins à Ho-Chi-Minh-Ville, Vietnam.

BACKGROUND: The transmission of hepatitis C virus (HCV) is strongly associated with blood transfusion and drug abuse. However, in about a third of HCV-infected subjects, the risk factors are not clearly identified though some cases are likely to be healthcare associated. In an Asian country such as Vietnam, invasive procedures used for traditional and beauty care could be potential risk factors. The aim of the present study was to identify the risk factors of HCV infection in a population sample in Ho Chi Minh City. METHOD: A case-control study matched by gender and age was performed among blood adults donors at the Centre of hematological diseases and blood transfusion. Cases were defined as blood donors with HCV-positive Elisa. Controls were selected at random among ELISA HCV-negative donors. A standardized questionnaire was used to collect data focusing on invasive medical procedures, beauty care and on invasive procedures related to traditional medicine. RESULT: Among the 80 cases and 240 controls, the independent predictors of anti-HCV positivity using a stepwise logistic regression were: blood transfusion, intravenous drug abuse, acupuncture, ventoused scarification and practice of scarification (adjusted odds ratio and IC95%: 3.8 [1.1-13.1], 3.5 [1.7-7.3], 5.4 [2.3-12.7], 5.4 [2.5-11.7], 6.6 [1.6-26.4] respectively). The other risk factors such as past hospitalization surgery, tattooing, being a healthcare worker, or practising tattooing or piercing were not associated with HCV infection. CONCLUSION: To be exposed to ventoused scarifications or acupuncture are risk factors for the transmission of HCV in Vietnam. A wide information campaign on hygiene practices for general population as well as the practitioners is needed to ensure safer health cares in traditional medicine.
