In this study, commercial media and kits for identification and tests for antibiotic susceptibility of genital mycoplasmas were evaluated in comparison to standardized methods. A total of 298 specimens was routinely enrolled. Our results showed that all media corresponded for qualitative and semiquantitative identification with a specificity of 100% for both microorganisms and a sensitivity of 94% for U. urealyticum and of 88% for M. hominis. Standard methods were superior to commercial kits for qualitative and quantitative identification (sensitivity 85-97% for U. urealyticum and 79-83% for M. hominis). There were large discrepancies when testing antibiotic susceptibility.

Epidemiology of ophthalmia neonatorum: a systematic review and meta-analysis.
BMC Pediatr
January 2025
Biomedical and Clinical Research Centre, College of Health and Allied Sciences, University of Cape Coast, Cape Coast, Ghana.
Purpose: To elucidate the global epidemiology of Ophthalmia Neonatorum (ON), as well as its causative organisms and their antibiotic susceptibility patterns.
Methods: A systematic review of studies reporting the epidemiology of ON was performed using four electronic databases: PubMed, Scopus, Web of Science, and Medline. Data were extracted and study-specific estimates were combined using meta-analysis to obtain pooled proportions.
Pseudocitrobacter cyperus, a novel bacterial species recovered from Cyperus alternifolius in Egypt.
BMC Microbiol
January 2025
Microbiology and Immunology Department, October University for Modern Sciences and Arts (MSA), Giza, Egypt.
Background: Strain Cyp38S was isolated as an endophyte from the plant Cyperus alternifolius, collected along the banks of the River Nile in 2019. Preliminary analysis tentatively identified Cyp38S as belonging to the genus Pseudocitrobacter.
Methods: The preliminary identification of Cyp38S was performed using the VITEK2 identification system, MALDI-TOF-MS, and 16S rRNA gene sequencing.
Decreased STING predicts adverse efficacy in bortezomib regimens and poor survival in multiple myeloma.
Clin Exp Med
January 2025
Stem Cell Immunity and Regeneration Key Laboratory of Luzhou, The Affiliated Hospital, Southwest Medical University, Luzhou, Sichuan, China.
Purpose: STING (stimulator of interferon genes) is involved in viral and bacterial defense through interferon pathway and innate immunity. Increased susceptibility to infection is a common manifestation of multiple myeloma (MM). Thus, we aimed to explore the clinical significance and possible mechanism of STING in MM.

January 2025
Laboratory of Veterinary Surgery and Ophthalmology, College of Veterinary Medicine, Chungbuk National University, Cheongju, Korea.
Objective: To investigate the impact of dexamethasone on the antibiotic susceptibility of common ocular pathogens in dogs and identify safe antibiotic-steroid combinations for veterinary ophthalmology.
Methods: This study utilized 30 bacterial isolates of Staphylococcus pseudintermedius, Streptococcus canis, and Pseudomonas aeruginosa, collected from canine patients with suspected bacterial keratitis. The isolates were tested against 17 antibiotics in the presence of dexamethasone concentrations ranging from 0 to 2 mg/mL.

Background: The investigation into risk factors, molecular epidemiology, and resistance mechanisms of carbapenem-resistant Pseudomonas aeruginosa (CRPA) in pediatric populations in China is currently inadequate.
Methods: To assess epidemiology, molecular characteristics, and resistance mechanisms, virulence-associated genes were analyzed, alongside multi locus sequence typing (MLST), PCR, and qRT-PCR.
Finding: Multivariate analysis identified prolonged hospitalization (OR: 1.
