    Comparison of Antibacterial Efficacy of Locally Produced Alcohol Based Hand Sanitizer and Commonly Available Commercial Hand Sanitizer Used in Healthcare Facilities in Uganda
    (Open Access Library Journal, 2020) Tusabe, Fred; Kasuswa, Sophia; Ssegawa, Alex; Busiinge, Emmanuel; Lusheda, Tom; Ampaire, Lucas
    Use of hand sanitizers has become a cornerstone in clinical practice for the prevention of disease transmission between practitioners and patients. There are a number of hand sanitizers sold on the Ugandan market with labels on their packages that claim that the hand sanitizer can kill 99.999% of germs and also there are hospitals that embarked on the local production of alcohol based hand sanitizer whose efficacy data are not locally available. Objective: To evaluate antibacterial efficacy of locally produced alcohol based hand sanitizer and commonly available commercial hand sanitizer used in healthcare facilities in Uganda. Method: This was an in vitro experimental, laboratory-based study of two different brands of hand sanitizers commonly used in healthcare facilities in Uganda and these were compared to a reference standard 60% Isopropyl alcohol. Efficacy was evaluated using standard organisms of Klebsiella pneumoniae American Type Culture Collection (ATCC 13883), Escherichia coli (ATCC 25922), and S. aureus (ATCC 25923) as per prEN12054, a European standard method. The logarithmic and percentage reduction factors (RF) were assessed at baseline and after treatment. Results: Both hand sanitizers studied were able to reduce bacteria by more than 105-fold within 15 seconds. Efficacy was independent of the alcohol concentration in each brand (Saraya 70% and locally made 80% alcohol). Conclusion: All of the hand sanitizers assessed had efficacy that meets World Health Organization (WHO) and PrEN12054 standards. From this study we are in agreement with the use of the locally made hand sanitizer and Saraya. The two hand sanitizers had broad antibacterial spectrum. However, there is a need to evaluate efficacy and organoleptic properties using in vivo studies.

    Asymptomatic carriage of Methicillin-Resistant Staphylococcus aureus (MRSA) can predispose the host to a wide array of infections that can be difficult to treat due to antibiotic resistance. To inform public health strategies, the study sought to describe MRSA nasal carriage frequencies and the associated factors concerning nasal carriage among patients attending Mbale Regional Referral Hospital (MRRH).Nasal swabs were obtained from consented (aged >15years) participants presenting to the hospital for medical care between January and April 2018 [L1] . Direct Culture of swabs was performed on blood agar and then incubated at 37℃ for 24 hours. Identification of S. aureus was done using conventional biochemical tests. Phenotypic screening and confirmation of MRSA was done using cefoxitin disc (30μg) test and MICs on the Phoenix M50 instrument respectively. Patient demographic characteristics and the MRSA nasal carriage risk factors were collected using a pre-tested questionnaire. Overall, majority of the participants were in-patients (138, 63.3%) with the proportions of both females and males among the participants being 154/218 (70.6%) and 64/218 (29.3%) respectively. Mean age for both female and male participants was 40.16 (SD± 17.04) years respectively. S . aureus nasal carriage rate among the participants was 22.9% (50/218), with 57.9% (29/50) of the harboured strains phenotypically expressing methicillin resistance ( mecA mediated). Phenotypic co-expression with i nducible clindamycin resistance and vancomycin resistance was displayed in 45.5% (23/50) and 2% (1/50) of the studied isolates respectively. Colonisation with MRSA did not show any significant relationship with all the studied factors.There was a moderate S. aureus nasal carriage among the participants in Mbale Regional Referral Hospital with a highly noted phenotypic expression of methicillin resistance among the isolated S. aureus strains. The studied factors were not significantly associated with the rate of MRSA nasal carriage. For surveillance purposes to combat future outbreaks, there is a need to do a larger study to better draw generalizable conclusions of carriage in the population.
