Background: Urinary tract infections (UTIs) are a prevalent form of urinary tract diseases affecting individuals of all ages and genders. In the Kingdom of Saudi Arabia (KSA), UTIs are a significant burden on the healthcare system, comprising 10% of all infections and ranking as the second leading cause of emergency department admissions. Despite this, limited research has been conducted in Saudi Arabia, particularly in Jazan Province, located in the southwestern region. Methods: This retrospective, cross-sectional study encompassed individuals with positive urine cultures who sought care at a tertiary hospital in Jazan between January 2022 and March 2023. A standardized data collection form was utilized to retrieve relevant information from microbiology lab test results and patients’ electronic medical records. Variables such as sex, urine sample collection date, bacterial isolates, antibiotic sensitivity, and resistance were collected using the data collection form. Data were analyzed using SPSS software, version 23.0 (IBM Corp., Armonk, NY, USA). Results: A total of 1082 urinary bacterial samples were isolated and identified. Females accounted for more bacterial infections (62.66%) than males (37.34%). Gram-negative bacteria represented 94% of all isolated strains. The most prevalent pathogens associated with UTIs were Escherichia coli (47.97%), Klebsiella pneumoniae (24.58%), and Pseudomonas aeruginosa (11.55%). Antimicrobial resistance patterns indicated the presence of extended-spectrum beta-lactamase (ESBL) (30.13%), carbapenemase-resistant Enterobacter (CRE) (1.94%), methicillin-resistant Staphylococcus aureus (MRSA) (0.74%), and vancomycin-resistant Enterococci (VRE) (0.18%). UTI incidence demonstrated a higher prevalence in September (13%) compared to other months in 2022. Escherichia coli, Klebsiella pneumoniae, and Pseudomonas aeruginosa were the predominant Gram-negative multidrug-resistant organisms (MDRO), accounting for 34.42%, 13.95%, and 1.63% of the population. Conclusions: The prevalence of UTIs caused by antibiotic-resistant microbes is notable in Jazan. Consistent with findings from other regions, Escherichia coli remains the most common causative pathogen of UTIs, displaying a seasonal pattern that warrants attention. Approximately 35% of reported cases involve MDRO, with ESBLs accounting for 30%. These results should raise concerns among healthcare officials, highlighting the necessity for further investigations into factors contributing to the circulation of MDRO in Jazan.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) continues to spread globally, causing unprecedented effects on global health and economies. Community-based serological data are essential for understanding the true prevalence of infections, specifically the subclinical infections, as COVID-19 asymptomatic infections are common. Such data would also be important for decision making around choosing appropriate epidemiological control measures, as well as for the true estimation of mortality rates in the population. Further, determining the seroprevalence of anti-SARS-CoV-2 antibodies in the population would provide important information on herd immunity. In this study, we conducted a population-based age-stratified serological study to understand the prevalence of SARS-CoV-2 in Jazan Province, Saudi Arabia. Out of 594 participants who were recruited from 29 August to 30 December 2020, just before the vaccination rollout program in Saudi Arabia, about 157 were seropositive for SARS-CoV-2, indicating an estimated seropositivity rate of 26%. Although no significant difference in seropositivity was seen between male and female participants, we found that lower seroprevalence was associated with the younger (below 18 years old) and older populations (older than 56 years) compared with other age groups (19–55 years). These data indicate a high prevalence of SARS-CoV-2 antibodies following the peak of COVID-19 spread in Jazan province; however, most of the population (three-quarters) remains susceptible to SARS-CoV-2 infection.

Healthcare-associated conjunctivitis (HAC) has been associated with serious ophthalmological complications in neonates, including blindness. This three-year retrospective, descriptive study was conducted between 2019 and 2021 to determine the most common bacteria associated with neonatal HAC at a tertiary-care hospital in Saudi Arabia. The inclusion criteria were defined based on the centers for disease control and prevention (CDC) guidelines for the diagnosis of neonatal HAC. When HAC was clinically suspected, conjunctival swabs were obtained from neonates and sent to the microbiology lab following standard protocols. A univariate analysis was conducted on the included samples. A total of 79 cases met our inclusion criteria and were retrospectively studied. A descriptive analysis showed that Pseudomonas aeruginosa was the leading cause of HAC, with 25% (20 cases), followed by Escherichia coli and Klebsiella pneumonia (11.5% for each). About 9% of the analyzed cases were positive for Staphylococcus aureus. Orogastric feeding was the most commonly (94%) associated factor with HAC, followed by respiratory distress syndrome (RDS) and preterm birth, which were found in 70% and 64% of the cases, respectively. To conclude, HAC is an alarming healthcare problem, and bacteria, including Gram-negative bacteria, are common causes. Thus, physician awareness, effective communication with microbiologists, and the implementation of infection control recommendations, including hand hygiene, could minimize this problem and avoid the serious complications of HAC.
