Methicilline resistente Staphylococcus intermedius. Een onderzoeksverslag: MRSI contaminatie en zoönotisch risico bij werknemers van dierenartsenpraktijken

Abstract

At the moment, the potential dangers of resistant pathogen are more and more acknowledged. Unfortunately, before one kind of resistant bacteria is overcome others have arisen. Therefore it is of big importance to get a good overview about the spread and carriage of methicillin resistant Staphylococcus intermedius (MRSI). This research has a triple goal: - Firstly, the retention of MRSI was checked within a few Dutch veterinary clinics. - Secondly, the zoönotic risks aspect for employees of veterinary clinics was observed. - Thirdly, an evaluation about hygienic- and cleaning protocols as a prevention of MRSI contamination within the veterinary clinic is made. Thirteen Dutch veterinary clinics in which one or more MRSI patients have been were part of this research. Seven of the 13 clinics had MRSI in its environment. Also, 155 employees were tested from whom in total 8 employees from 3 different clinics tested positively for MRSI from nose swab samples. Nasal carriage by these persons was not proven nor denied within this research. Six of the 13 clinics had no hygienic- or cleaning protocols. Seven clinics did have protocols but employees of 4 of these clinics did not know the protocol or did not work according to them. During this research no link was found between the absence and presence of MRSI in the environment and absence and presence of protocols in the clinics. The spread and presence of MRSI in the environment is most likely determined by multiple factors.
