Microbiological Assessment of Automated Teller Machine Keypads as Reservoirs of Potentially Pathogenic Bacteria in Nigerian Cities

Frequently touched public surfaces can serve as reservoirs for microbial contamination and facilitate transmission of potentially pathogenic organisms. Automated teller machine keypads are used daily by large numbers of individuals and may accumulate bacteria from diverse sources. The presence of antibiotic-resistant bacteria on these surfaces could contribute to community transmission of resistant pathogens. Understanding contamination patterns on public-use devices can inform hygiene awareness campaigns and public health interventions. This study seeks to evaluate bacterial contamination and resistance profiles associated with automated teller machine keypads.

Determinants of Childhood Immunization Defaulting Among Caregivers Attending Primary Healthcare Facilities in Rural North-West Nigeria

Childhood immunization remains one of the most effective public health interventions for preventing vaccine-preventable diseases. Despite improvements in immunization coverage across Nigeria, several northern states continue to report suboptimal vaccination uptake and high rates of immunization defaulting. Factors such as vaccine hesitancy, poor healthcare access, low maternal education, cultural beliefs, insecurity, and health system constraints contribute to missed vaccination opportunities. Immunization defaulting increases the risk of disease outbreaks, childhood morbidity, and mortality. Understanding the specific factors influencing caregivers' adherence to vaccination schedules is essential for designing targeted interventions that improve vaccine completion rates. Evidence from rural communities remains limited despite their disproportionate burden of under-immunization. This study seeks to identify determinants of childhood immunization defaulting among caregivers attending primary healthcare facilities in rural North-West Nigeria and generate evidence to support context-specific immunization strategies.

Knowledge, Risk Perception and Acceptance of Human Papillomavirus Vaccination Among Female Undergraduate Students in Nigerian Universities

Cervical cancer remains a leading cause of cancer-related morbidity and mortality among women in Nigeria. Human papillomavirus vaccination offers a highly effective strategy for reducing the burden of cervical cancer. However, vaccine uptake remains low due to inadequate awareness, misconceptions, cultural concerns, cost barriers, and limited access. Female university students represent an important target population for preventive interventions because they are at an age where vaccination can still provide substantial benefits. Understanding knowledge levels, risk perception, and vaccine acceptance among young women is critical for developing effective awareness campaigns and vaccination programs. This study seeks to evaluate factors influencing acceptance of human papillomavirus vaccination among female undergraduate students in Nigerian universities.

Occurrence of Multidrug-Resistant Campylobacter Species in Broiler Chickens and Retail Poultry Meat in Nigeria

Campylobacter species are among the leading bacterial causes of gastroenteritis worldwide and are frequently associated with poultry products. Poultry production systems can serve as reservoirs of multidrug-resistant Campylobacter strains, creating significant food safety and public health concerns. The widespread use of antibiotics in poultry farming may contribute to resistance development. Despite increasing poultry consumption in Nigeria, data on the prevalence and resistance characteristics of Campylobacter species remain limited. This study seeks to investigate the occurrence and antimicrobial resistance profiles of Campylobacter isolates from poultry sources.

Prevalence and Molecular Detection of Shiga Toxin-Producing Escherichia coli in Raw Beef Sold in Major Abattoirs in South-West Nigeria

Shiga toxin-producing Escherichia coli (STEC) are important foodborne pathogens capable of causing severe gastrointestinal disease, hemorrhagic colitis, and hemolytic uremic syndrome. Raw meat products may become contaminated during slaughtering, processing, or transportation. In Nigeria, increasing demand for fresh meat and variations in hygienic practices within abattoirs raise concerns regarding food safety and public health. Molecular detection of shiga toxin genes provides a reliable approach for identifying potentially pathogenic strains. Understanding the prevalence and molecular characteristics of STEC in beef products is essential for strengthening food safety surveillance and reducing foodborne disease risks.

Microbial Contamination and Antimicrobial Resistance Profiles of Mobile Phones Used by Healthcare Workers in Nigerian Teaching Hospitals

Mobile phones are widely used by healthcare workers for communication and clinical activities. Frequent handling of devices in patient care environments may facilitate microbial contamination and contribute to transmission of healthcare-associated pathogens. The presence of antibiotic-resistant bacteria on mobile phones represents an additional infection control concern. Understanding contamination patterns and resistance characteristics of bacterial isolates can support development of effective infection prevention strategies. This study seeks to assess microbial contamination and antimicrobial resistance among bacteria isolated from healthcare workers' mobile phones.

Prevalence and Resistance Patterns of Enterococcus Species Isolated From Clinical Specimens in Tertiary Healthcare Facilities in Nigeria

Enterococcus species are important opportunistic pathogens increasingly associated with healthcare-associated infections. The emergence of multidrug-resistant and vancomycin-resistant strains poses significant challenges to patient management and infection control. Surveillance of resistance patterns is essential for guiding antimicrobial stewardship programs and informing treatment decisions. Despite growing concerns about resistant Enterococcus species, epidemiological data remain limited in many Nigerian healthcare settings. This study seeks to investigate the prevalence and resistance characteristics of Enterococcus species isolated from clinical specimens.

Occurrence and Molecular Detection of Listeria monocytogenes in Locally Produced Dairy Products Sold in Urban Markets in Nigeria

Listeria monocytogenes is a foodborne pathogen capable of causing severe illness, particularly among pregnant women, newborns, older adults, and immunocompromised individuals. Dairy products can serve as important vehicles for transmission when contamination occurs during production, processing, or storage. Despite increasing consumption of locally produced dairy products in Nigeria, surveillance data on Listeria contamination remain limited. Understanding contamination rates and molecular characteristics of isolates is important for strengthening food safety monitoring systems and protecting public health.

Antibiotic Resistance and Biofilm Production Among Coagulase-Negative Staphylococci Isolated From Indwelling Medical Devices in Nigerian Hospitals

Coagulase-negative staphylococci have emerged as important opportunistic pathogens associated with medical device-related infections. Their ability to form biofilms enhances persistence on artificial surfaces and contributes to treatment failure. Biofilm-associated infections are difficult to eradicate because bacterial cells within biofilms often exhibit increased resistance to antimicrobial agents. Understanding resistance patterns and biofilm-forming capabilities among clinical isolates is essential for infection prevention and improved patient management. This study investigates antibiotic resistance and biofilm production among coagulase-negative staphylococci isolated from indwelling medical devices.
