Rates of Multidrug-Resistant Gram-Negative Bacterial Infections in Hospitalized Non-Immunocompromised Pediatric Patients: A 9-Year Retrospective Study at a Lebanese Tertiary Medical Center.
Infect Drug Resist
January 2025
Center for Infectious Diseases Research (CIDR) and WHO Collaborating Center for Reference and Research on Bacterial Pathogens, American University of Beirut, Beirut, Lebanon.
Introduction: Multidrug resistant (MDR) Gram-negative bacterial infections are considered a major public health threat. The objectives of this study were to describe the epidemiology, potential contributing factors, and antimicrobial resistance patterns associated with infections caused by MDR Gram-negative bacteria (GNB) in non-immunocompromised children and adolescents.
Methods: This was a retrospective observational study conducted at the American University of Beirut Medical Center (AUBMC) from 2009 to 2017.
A Four-Year Study of Antibiotic Resistance, Prevalence and Biofilm-Forming Ability of Uropathogens Isolated from Community- and Hospital-Acquired Urinary Tract Infections in Southern Italy.

January 2025
Department of Human Pathology, University of Messina, 98125 Messina, Italy.
The aim of this study was to investigate the differences between nosocomial and community microorganisms isolated from patients with UTI by determining their bacterial profile, antibiotic resistance and ability to produce biofilms. A retrospective study, based on bacterial isolates from consecutive urine samples collected between January 2019 and December 2023, was conducted at a university hospital. The main pathogens isolated from both community and hospital samples were the same, but their frequency of isolation differed.

Article Synopsis
- The intratumoral microbiome, particularly the anaerobic Gram-negative bacterium associated with the oral cavity, plays a crucial role in the progression of pancreatic cancer, which is one of the deadliest cancers.
- This bacterium, recognized as an oncobacterium, contributes to tumor development through various mechanisms such as immune modulation, virulence factors, and interactions affecting cell proliferation and DNA damage.
- Research indicates that the presence of this bacterium not only serves as a prognostic marker for pancreatic cancer but also relates to resistance to chemotherapy, highlighting its potential for use as a tumor biomarker and a target for developing new cancer treatments.
The Bacterial Type III Secretion System as a Broadly Applied Protein Delivery Tool in Biological Sciences.

January 2025
College of Forestry and Grassland, Nanjing Forestry University, Nanjing 210037, China.
The type III secretion system (T3SS) is a nano-machine that allows Gram-negative bacteria to alter eukaryotic host biology by directly delivering effector proteins from the bacterial cytoplasm. Protein delivery based on the bacterial T3SS has been widely used in research in biology. This review explores recent advancements in the structure and function of the T3SS.

Department of Human Pathology, University of Nairobi, Nairobi, Nairobi County, Kenya.
Background: Bacterial infections in the Intensive Care Units are a threat to the lives of critically ill patients. Their vulnerable immunity predisposes them to developing bacteria-associated sepsis, deteriorating their already fragile health. In the face of increasing antibiotics resistance, the problem of bacterial infection in ICU is worsening.
