Objective: Description of knowledge on prevention of surgical site infections (SSIs) among medical staff in Son Tay general hospital, 2021 and some related factors.Method: A cross-sectional study was conducted on 151 medical staff.Results: The rate of medical staff with fully knowledge of SSI prevention is 36.42%, in which the rate of doctors is 38.3% and of nurses is 35.58%. Age group ≥30 (OR=2.82; 95%CI: 1.12 – 7.13);Department of Surgery (OR=13.61; 95%CI: 5.14 – 35.98); working year ≥10 (OR=2.54; 95%CI: 1.26 – 5.11) and number of patients cared for/day <8 (OR=3.43; 95%CI: 1.26 – 9 ,34) are factorsrelated to the knowledge of medical staff about regarding SSIs.Conclusion: The medical staff’s knowledge of surgical site infection prevention is suboptimal; relevant factors should be considered when conducting ongoing training in the prevention of surgical site infections in hospitals.

Fusarium proliferatum has been identified as the causal pathogen of Fusarium root rot of Ba kich (Morinda officinalis) (FRRBK). No studies are available regarding the effectiveness of chemical treatments on the disease incidence of FRRBK. The efficacy of five active ingredients (metconazole, prochloraz, tebuconazole, kresoximmethyl, and pyraclostrobin) from two chemical groups (demethylation inhibitors and quinone outside inhibitors) in reducing three isolates (BKVN, BKDT, and BKPL) of F. proliferatum mycelial growth was tested in vitro. The results indicate that only metconazole, prochloraz, and tebuconazole are highly effective in inhibiting the mycelial growth of F. proliferatum. These were selected for investigation of their efficacy with regard to the disease incidence of FRRBK in pot and in field conditions. Prochloraz and metconazole showed the highest efficacy and significantly suppressed the disease incidence of FRRBK in pot and in field conditions.
