Article Abstract
Background: Surgical site infections (SSIs), especially when caused by multidrug-resistant (MDR) bacteria, are a major healthcare concern worldwide. For optimal treatment and prevention of antimicrobial resistance, it is important for clinicians to be aware of local drug-resistant bacterial pathogens that cause SSIs.
Objective: To determine the frequency patterns of drug-resistant bacterial strains causing SSIs at a tertiary care hospital in Saudi Arabia.
Methods: This retrospective study was conducted at the Microbiology laboratory of Al-Noor Specialist Hospital, Makkah, Saudi Arabia, and included wound swab samples from all cases of SSI between January 01, 2017, and December 31, 2021. The swabs were processed for the identification of bacterial strains and their resistance pattern to antibiotics according to the Clinical and Laboratory Standards Institute.
Results: A total of 5409 wound swabs were analyzed, of which 3604 samples (66.6%) were from male. Most samples were from the Department of Surgery (43.3%). A total of 14 bacterial strains were isolated, of which 9 were Gram-negative bacteria. The most common isolates were , followed by , , , methicillin-resistant (MRSA), vancomycin-resistant Enterococci (VRE), and vancomycin-resistant (VRSA). In terms of MDR in 2021, the highest rate of carbapenem-resistance was in (97%). MDR was as follows: , 97%; , 81%; , 71%; MRSA, 60%; , 33%; VRE, 22%; and VRSA, 2%.
Conclusion: This study showed that in the city of Makkah, Saudi Arabia, the rates of MDR bacteria are high, with the majority being Gram-negative.
Clinical symptoms of infection (CDI) range from diarrhea to pseudomembranous colitis. A major challenge in managing CDI is the high rate of relapse. Several studies correlate the production of CDT binary toxin by clinical strains of with higher relapse rates.
Objective: To investigate the molecular typing characteristics, drug resistance status and drug resistance gene carrying of food-borne Staphylococcus aureus in Ningxia.
Methods: Staphylococcus aureus isolated from food safety risk monitoring project in Ningxia in the past ten years were collected, drug resistance was detected using microbroth dilution method, enterotoxins were detected by real-time PCR. The strains were genotyped by pulsed field gel electrophoresis(PFGE) using SmaI endonuclease.
Background: Urinary tract infections (UTIs) are among the most common bacterial infections, and appropriate antimicrobial therapy with agents that minimise resistance is crucial. Despite international concern, adherence to guidelines is still suboptimal. This study aims to determine the effect of the absence of national guidelines and the rate of conformity to international guidelines among physicians in antibiotic (ATB) prescriptions for the treatment of UTIs in adults and detect the factors that are associated with a higher rate of non-compliance.
Dipeptides were constructed using hydrophobic amino acid residues following AMP prediction. After that Boc-modification was performed on the screened peptides and finally Boc-Phe-Trp-OMe and Boc-Trp-Trp-OMe were synthesized. Even though no inhibition zones were observed in agar well diffusion assays, minimum inhibitory concentration (MIC) analysis revealed anti-bacterial activity against both Gram-positive and Gram-negative bacteria, with MIC ranging from 230 to 400 μg/mL.

Antibiotic resistance by methicillin-resistant Staphylococcus aureus (MRSA) is an urgent threat to human health. The biofilm and persister cells formation ability of MRSA and Staphylococcus epidermidis often companied with extremely high antimicrobial resistance. Pinaverium bromide (PVB) is an antispasmodic compound mainly used for irritable bowel syndrome.
