Increased susceptibility to bacterial recurrent infection is characteristically associated with impaired B cells function but also with a defective PMN function. We studied PMN CT in 15 HIV positive drug addicts patients with persistent generalized lymphoadenopathy (PGL), in 15 symptom free HIV negative drug addicts (SFDA) and in 15 healthy blood donors to evaluate influence of HIV infection on PMN functions. CT of patients with PGL was reduced to 78% (p < 0.0001) and 75% (p < 0.00001) of CT in SFDA patients and healthy blood donors, respectively. We conclude that HIV infection causes defective PMNL CT and then it can increase susceptibility to bacterial recurrent infections in these patients.

Introduction: The widespread use of antibiotics is a serious and alarming situation in terms of the development of antimicrobial resistance. The current study was conducted to demonstrate the types of organism isolated from the urine of patients presenting with UTI symptoms as well as their antimicrobial sensitivity spectrum.
Methodology: A descriptive cross-sectional study was conducted, and 272 positive urine cultures from children under 5 years of age with signs and symptoms of a UTI were included in the study.

Background: Meningitis is highly prevalent in infant because their immune system is immature and they have less resistance to diseases. Among bacterial agents, is recognized as one of the most important causes of meningitis in infants.
Case Presentation: Herein, we report a case of late-onset meningitis, caused by (Patient:17-day-old female infant).

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.

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.

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.
