Abstract
Background Commensal flora colonization during hospitalization by bacteria is the first step for nosocomial infections while antibiotic resistance reduces therapeutic options. In aim to control this phenomenon, we initiated this study to describe the impact of hospitalization on colonization by methicillin-resistant Staphylococcus aureus in the surgical department of 03 health facilities in the Ndé division, West-Cameroon. Methods This study was carried out on patients admitted for surgery in 03 health facilities of the Ndé division, West-Cameroon (District Hospital of Bangangté, Protestant Hospital of Bangwa and Cliniques Universitaires des Montagnes). After obtaining ethical clearance and authorizations, nasal swabs were performed at admission and discharge, with the aim of isolating bacteria and performing their antibiotic susceptibility tests. Informations on each participant's antibiotic therapy were recorded. Laboratory investigations were carried out according to standard protocols (CASFM, 2019). Results The most commonly used antibiotics were β-lactams. A total of 104 nasal swabs were performed on 52 patients who agreed to participate to the study. From the analysis, 110 (57 at admission versus 53 at discharge) Staphylococcus isolates were obtained. Overall, susceptibility testing showed that antibiotic resistance rates were higher at discharge than at admission; with significant differences between the susceptibility profiles obtained at admission and discharge for β-lactams and not significant for fluoroquinolones and aminoglycosides. Globally, frequency of nasal carriage of methicillin-resistant Staphylococcus aureus at discharge 16 (30.77%) was significantly higher than at admission 07 (13.46%) with Chi-2 = 4.52 and p = 0.0335. Conclusion The high rates of antibiotic resistance of bacteria isolated at discharge compared to those isolated at admission obtained in the present investigation, highlights the important role that hospitalization plays in the selection and dissemination of methicillin-resistant Staphylococcus aureus and colonization by these bacteria in health structures of Ndé division. As a result, further investigations to find the factors that promote this phenomenon should be carried out.

Abstract
UNLABELLED The fight against healthcare-associated infections is based on preventive measures of multidrug resistant bacteria diffusion. Hand hygiene is the simplest and the most effective preventive measure to reduce cross-transmission of infectious agents. Hydroalcoholic solutions for hand hygiene was recently introduced in the University Hospital of Brest (France). The aims of the study were: to describe the epidemiology of healthcare-associated infections due to methicillin-resistant Staphylococcus aureus (MRSA); to determine the annual consumptions of antistaphylococcal antibiotics; and to discuss the relation between consumption of antiseptic products or antibiotics and the epidemiology of MRSA. METHODS A retrospective epidemiological and pharmaco-epidemiological study was realized from January 2004 to December 2007 in the University Hospital of Brest (France). It allowed to bring to light the cases of healthcare-associated infections due to MRSA and to quantify the consumptions of hang hygiene products and antistaphylococcal antibiotics. RESULTS this retrospective study showed a decrease of healthcare-associated infections due to MRSA and an increase of the consumption of hydroalcoholic solutions. Antistaphylococcal resistance rates also decreased in a context of fall of the global antibiotics consumption in the hospital.
