The aim of this study is to compare the nasopharyngeal microbiota of healthy subjects, moderate, under medication, and recovered SARS-COV-2 patients.

Side effects of COVID-19 vaccines in the middle eastern population.

The COVID-19 pandemic has caused severe worldwide health concerns since its first description as the SARS-COV-2 virus in December 2019. The wide dissemination of this virus, together with the lack of treatment, prompted vaccine development within a short period of time to elicit a protective immunity against COVID-19. Due to their rapid development, potential subsequent side effects of COVID-19 vaccines were overlooked, which might lead to many health concerns.

Prevalence of Common Respiratory Viruses in Children at a Tertiary Care Hospital in Saudi Arabia.

Acute lower respiratory viral infections are significant contributors to morbidity/mortality in children less than 2 years of age. In this retrospective study conducted at a major hospital, between 2017 and 2019, it was observed that rhinovirus, respiratory-syncytial-virus and influenza virus are the most frequently detected with the seasonal distribution. Mortality rate was significantly higher in children less than 12 months and significantly increased in males and in those requiring intubation.

Antibacterial effect of a diet pill supplement on the human intestinal bacteria.

Medical, radiological, pathological, and laboratory reports of 146 NPC patients were collected retrospectively over a 6-year period between 2015 and 2020.

Prognosis of COVID-19 in the middle eastern population, knowns and unknowns.

Since its emergence in China in 2019, the SARS-CoV-2 virus has affected all countries worldwide. The virus is easily transmitted from one person to another infected aerosols or contaminated surfaces. Unlike its counterparts, the prognosis of COVID-19 ranges from asymptomatic to critical disease or death.

Genome analysis of isolated from a patient after kidney transplantation in Marseille.

is a new species in the genus . is a Gram-positive anaerobic rod. This strain, Marseille-P3177 (CSUR = P3177) with the below described genome was isolated from the urine sample of a women after kidney transplantation.

Acinetobacter spp in a Third World Country with Socio-economic and Immigrants Challenges.

Introduction: In the last decade, Acinetobacter species have taken a major public health concern. This is mainly due the increased resistance to a wide range of antibiotics causing treatment challenges. In view of the constant population mobilization and the economic crisis that Lebanon is currently facing, it becomes a necessity to re-evaluate the real threat of Acinetobacter spp and its implication in the one health.

Dissemination of Multidrug-Resistant and Gram-Negative Bacilli in Broilers, Farm Workers, and the Surrounding Environment in Lebanon.

Poultry are currently regarded as reservoirs from which multidrug resistance can be readily transferred to the surrounding ecosystem. The aim of this study was to explore the prevalence of extended spectrum beta-lactamases (ESBLs) and ampC and Gram-negative bacilli in chicken, farmers, and environment in Lebanon. In May 2017, we revisited the farm where the first was detected in 2015 in Lebanon.

Understanding the Epidemiology of Multi-Drug Resistant Gram-Negative Bacilli in the Middle East Using a One Health Approach.

In the last decade, extended-spectrum cephalosporin and carbapenem resistant Gram-negative bacilli (GNB) have been extensively reported in the literature as being disseminated in humans but also in animals and the environment. These resistant organisms often cause treatment challenges due to their wide spectrum of antibiotic resistance. With the emergence of colistin resistance in animals and its subsequent detection in humans, the situation has worsened.

Analysis of CAST in 9 Lebanese hospitals between 2008 and 2017.

Background: Cumulative Antibiotic Susceptibility Testing (CAST) plays a crucial role in providing knowledge about the evolution of bacterial resistance. The preparation of such report is however prone to many errors. This study investigated the variety of mistakes detected in the CAST of 9 Lebanese hospitals.

Prevalence and Emergence of Extended-Spectrum Cephalosporin-, Carbapenem- and Colistin-Resistant Gram Negative Bacteria of Animal Origin in the Mediterranean Basin.

In recent years, extended ESBL and carbapenemase producing Gram negative bacteria have become widespread in hospitals, community settings and the environment. This has been triggered by the few therapeutic options left when infections with these multi-drug resistant organisms occur. The emergence of resistance to colistin, the last therapeutic option against carbapenem-resistant bacteria, worsened the situation.

Colistin- and Carbapenem-Resistant Klebsiella pneumoniae Clinical_Isolates: Algeria.

This study investigates the molecular mechanisms of colistin and carbapenem resistance in Klebsiella pneumoniae ST101 strains. The three K. pneumoniae carried bla, bla, and bla genes and two coharbored bla.

Prevalence of Extended-Spectrum Beta-Lactamase-Producing Gram-Negative Bacilli and Emergence of mcr-1 Colistin Resistance Gene in Lebanese Swine Farms.

Livestock are considered reservoirs of multidrug-resistant organisms that can be transferred to humans through direct/indirect routes. Once transmitted, these organisms can be responsible for infections with therapeutic challenges. The aim of this study was to determine the prevalence of extended-spectrum cephalosporin and colistin-resistant Gram-negative bacilli in Lebanese swine farms.

Prevalence and Characterization of Multi-Drug-Resistant Gram-Negative Bacilli Isolated From Lebanese Poultry: A Nationwide Study.

Currently, antimicrobial resistance is one of the most prominent public health issues. In fact, there is increasing evidence that animals constitute a reservoir of antimicrobial resistance. In collaboration with the Lebanese Ministry of Agriculture, the aim of this study was to determine the prevalence of intestinal carriage of multi-drug-resistant Gram-negative Bacilli in poultry farms at the national level.

Carriage trends and fitness cost of MDROs in Lebanese nursing homes.

Introduction: Nowadays, medical treatments efficiency is challenged by multi drug resistant organisms (MDROs). Lebanese nursing homes' residents revealed high fecal carriage rates of MDR Enterobacteriacea. Previous studies claim that bacteria with resistant genes experience fitness cost.

Competition assays between ESBL-producing E. coli and K. pneumoniae isolates collected from Lebanese elderly: An additional cost on fitness.

The dissemination of Multi Drug Resistant Organisms (MDROs) is one of the major public health problems addressed nowadays. High fecal carriage rates of MDR Enterobacteriaceae were reported from Lebanese nursing homes. Studies have shown that the acquisition of resistance genes by bacteria might confer a fitness cost detected as a decrease in the frequency of these bacteria as compared to sensitive isolates.
