Introduction: Diarrhoea accounts for high morbidity and mortality in children and adults worldwide. Extended Spectrum Beta-Lactamase-Producing Enterobacteriaceae (ESBL-PE) and Diarrhoeagenic Escherichia coli (DEC) contribute to prolonged hospitalization because of their resistance and virulence properties aiding in the spread of diarrhoeal disease and delayed treatment. Aim: To determine DEC and the antimicrobial resistance of ESBL-PE isolated among diarrhoea patients attending two health facilities in Ghana. Methods: Stool samples were collected from 122 diarrhoeal patients who attended Maamobi General Hospital and Kaneshie Polyclinic between January 2019 and March 2020. Identification of bacteria was performed by using the Matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS). Using disk diffusion, antimicrobial susceptibility testing (AST) was conducted and interpreted according to the 2018 CLSI guidelines. Detection of ESBL and DEC genes was performed using Polymerase chain reaction (PCR). Results: A total of 80.3% (98/122) Enterobacteriaceae was recovered from the patients in the study with an overall ESBL occurrence of 20.4% (20/98), predominantly among E. coli showed 13.2% (10/76), Klebsiella pneumoniae,35.7%(5/14) and Proteus mirabilis, 57.1%(4/7). Among the ESBL genes detected, bla_TEM (n = 14) was common, followed by bla_CTX-M (n = 13) and bla_SHV (n = 4). Thirty-four E. coli isolates possessed the heat labile (Lt) gene of Enterotoxigenic E. coli (ETEC). Conclusion: Our findings confirm the existence of DEC and the antimicrobial resistance patterns of ESBL-PE among stool isolates, limiting the options of commonly used drugs for diarrhoeal treatment in Ghana. Routine laboratory testing in health care facilities and strengthened surveillance systems among hospital networks are encouraged for a better understanding of their epidemiology and clinical implications.

Understanding the underlying epidemiology that shapes Neisseria gonorrhoeae (GC), and Chlamydia trachomatis (CT) infections can contribute to data driven policies directed towards curbing the proliferation of these pathogens in Ghana. Information on the symptoms and risk factors for STIs will help to identify high-risk individuals which will in turn inform STI syndromic management and tailor the use of public health resources. Participants were from 4 military clinics and 1 civilian STI clinic in Ghana and eligible if they had symptoms suggestive of STI. First void urine samples were collected and tested with Nucleic Acid Amplification Test (NAAT). A structured questionnaire was administered to all participants. Multivariate logistic regression identified factors associated with infection, separately for NG and for CT and for men and women. A total of 950 patients, 58% of whom were females were enrolled, 28% had gonorrhea and 11% had chlamydia with more males testing positive than females. Reported symptoms that were more common among patients who tested positive for gonorrhea were painful urination and urethral discharge (all P values < 0.05). Additionally, multiple sexual partners and alcohol use were statistically associated with higher rates of gonorrhea in males while only the frequency of condom use was associated with gonorrhea for females. None of the symptoms or risk factors except marital status was associated with testing positive for chlamydia. Identifying these symptoms and risk factors help inform health care delivery systems for STIs in Ghana. Furthermore, men and women presenting with these symptoms and risk factors are a prime target for public health education campaigns, aimed at curbing the spread of gonorrhea and chlamydia infections.

This study sought to investigate microbial quality and antimicrobial resistance of bacteria species from Ready-to-Eat (RTE) food, water, and vendor palm swab samples. Between 2019 and 2020, RTE food, water and vendor palm swab samples were collected from food vending sites in Accra, Ghana. Samples were cultured and confirmed using the Matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF). Antimicrobial susceptibility testing (AST) was conducted using disk diffusion method. Beta-lactamase and Diarrheagenic Escherichia coli (DEC) genes were determined using Polymerase Chain Reaction (PCR). Total plate count (TPC) and Total coliform count (TCC) were performed on food and water samples. In total, 179 RTE food, 72 water and 10 vendor palm swab samples were collected. Enterobacter spp. (16.8 %), Citrobacter spp. (10.1 %), Enterococcus faecalis (7.8 %), Pseudomonas spp. (6.7 %) and Klebsiella pneumoniae (4.0 %) occurred in food. Isolates from water and palm were Klebsiella pneumoniae (20.8 %), Aeromonas spp. (16.7 %) and Enterobacter cloacae (11.1 %). Resistance to Amoxicillin-clavulanate, Tetracycline, Azithromycin, Sulfamethoxazole-trimethoprim, and Nitrofurantoin were common among Enterobacterales. High mean TPC and TCC showed in some RTE food and different water types used in vending depicting their unsafe condition for consumption and usage. The bla_SHV and bla_TEM genes were present in some Enterobacterales from food and water. The lt gene was identified in two food samples. AMR organisms associated with nosocomial infections in the samples investigated, calls for continuous surveillance in the food industry in Ghana. Also, the unsafe outcome of RTE food and water depicts the need for the enforcement of Ghana's food safety laws.

Mycoplasma genitalium (MG), a sexually transmitted infection (STI), has emerged as a common cause of non-gonococcal urethritis and cervicitis worldwide, with documented resistance to commonly used antibiotics including doxycycline and azithromycin. Data in Ghana regarding the prevalence of MG is limited. This retrospective study investigated MG presence and macrolide resistance among patients who previously reported to selected clinics for STI symptoms between December 2012 and June 2020. Samples were screened for MG and mutations associated with azithromycin resistance were investigated using Nucleic Acid Amplification Testing (NAAT) including the Resistance Plus MG® kit from SpeeDx and the LightMix® kit for MG, combined with the Modular Mycoplasma Macrolide from TIB Molbiol. A total of 1,015 samples were screened, out of which MG infection rate by TIB Molbiol and SpeeDx were 3.1% and 3.4%, respectively. The mutation responsible for macrolide resistance was detected in one MG positive sample by both assays. Both diagnostic tests revealed no significant association between MG infection and socio-demographic characteristics, clinical symptoms, gonorrhea, and chlamydia infection status. There was no significant difference in the mycoplasma percentage positivity rate detected using SpeeDx (3.4%) and TIB Molbiol (3.1%). While not commonly tested as a cause of STI symptoms, MG is widespread in Ghana, exhibiting symptoms and prevalence comparable to those in other countries and linked to antimicrobial resistance. Future research using various molecular techniques is essential to monitor resistance trends and guide future antibiotic choices.

Background/Objectives: Zoonotic tuberculosis (TB) remains a persistent public health challenge worldwide. It is particularly common in settings with close human–livestock–environment interactions. In Tanzania, progress toward TB control is increasingly threatened by multidrug-resistant tuberculosis (MDR-TB), yet genomic data from regions characterized by pastoralist and mining activities remain scarce. This study employed whole-genome sequencing (WGS) to characterize M. tuberculosis complex (MTBC) strains circulating among human and cattle populations in the Manyara region of northern Tanzania, with a focus on resistance-associated mutations and phylogenetic relationships. Methods: This cross-sectional study was conducted between September 2024 and February 2025. A total of 178 presumptive human TB cases provided sputum samples. From cattle, 161 samples were collected (110 milk samples and 51 lymph node aspirates), with each animal contributing only one type of sample. Specimen were analyzed using GeneXpert MTB/RIF, Lowenstein–Jensen culture, and WGS. Phylogenetic reconstruction was performed using SNP-based methods and IQ-TREE2 version 2.2.0. Results: Among human participants, 14 (7.8%) sputum samples were GeneXpert positive and were confirmed as members of MTBC by LJ culture. In cattle, one (0.62%) lymph node aspirate was positive for MTBC. Significant predictors of MTBC positivity included previous TB history, weight loss, and occupation involving mining and cattle keeping. WGS of five human isolates identified Lineages 1, 3, and 4. One isolate (Sample 98) harbored mutations associated with XDR-TB. Conclusions: WGS revealed M. tuberculosis Lineages 1, 3 and 4 circulating in the Manyara region, with diverse genetic mutations conferring with resistance to first- and second-line anti-TB drugs. These findings highlight the importance of integrated genomic surveillance to monitor drug resistance patterns in Tanzania and similar settings across human and animal populations.
