Abstract:
Background: Public transportation including town buses, play a major role in the spread of multidrug-resistant (MDR) bacterial strains that have their origin in hospitals or communities. MDR bacteria isolated from clinical environment of Tanga Regional Referral Hospital (TRRH) can spread to the community through public transport particularly town buses. There is limited information from Tanga and Tanzania in general on MDR-bacterial contamination from public transports (Town bus surfaces).
Objective: To determine the prevalence, antibiotic resistance pattern of MDR bacteria including MRSA, and ESBL-E. coli, ESBL- K. pneumoniae, ESBL-Enterobacter spp., MDR-A. baumannii and MDR-P. aeruginosa from highly touched surfaces of public town buses and compare the level of contamination with MDR bacteria among the town buses serving the hospital route versus nonhospital (community) route.
Methods: A cross-sectional study was carried out in Tanga City, Tanzania from June 2024 to August, 2024 that involved sampling of highly touched surfaces of public town buses.
Results: Out of 482 swabs that were collected 61/482 (12.7%) were positive for MDR bacteria. Overall positivity rate of MRSA, ESBL-Enterobacter spp., ESBL- E. coli, ESBL-K. pneumoniae, MDR- A. baumannii, and MDR-P. aeruginosa were 28 (5.8%), 14(2.9%), 10 (2.1%), 5 (1.0%), 3(0.6%) and 1(0.2%), respectively. Among the public town buses, the most contaminated highlytouched surfaces were seats 22 (4.6%) and grab rails 10 (2.2%). The hospital route had higher MDR contamination than non-hospital route 39 (16.5%) vs 22 (9%), P=0.012).
Conclusion and Recommendation: Our study revealed that public transport particularly town buses were contaminated with MDR bacteria including Methicillin resistant S. aureus (MRSA), ESBL Enterobacterales, MDR-A. baumannii as well as MDR P. aeruginosa. The hospital routes had high MDR-contamination compared non-hospital route, and the most contaminated highly touched surface of town buses were the seats. Hospital visitors should always practice handwashing and applying sanitizers before boarding and disembarking from the public town buses. This will reduce the possibility of contaminating public transport (buses) when hospital visitors or patients come into contact with the surfaces of public town buses.
