Ear Nose & Throat Journal, Год журнала: 2025, Номер unknown

Опубликована: Янв. 7, 2025

Objective: Secondhand smoke (SHS) is a major public health concern. In this study, we evaluated the global burden of otitis media (OM) due to SHS exposure during 1990-2019 and explored impact socioeconomic factors on it. Methods: With reference 2019 Global Burden Disease (GBD) data, assessed OM linked 1990-2019, stratified by gender, GBD region, country. Join-point regression models analyzed trends in calculating average annual percent change (AAPC). Spearman’s correlation examined relationship between Socio-demographic Index (SDI), Healthcare Access Quality (HAQ) index, SHS-related burden. Results: During age-standardized disability-adjusted life years (ASDRs) mortality rates (ASMRs) for declined globally, with AAPCs −1.45 ASDR −7.97 ASMR. Significant declines ASMR were noted low-to-middle SDI regions. Regionally, Eastern Sub-Saharan Africa had highest OM-related deaths, while South Asia years. decreased higher HAQ. Conclusion: Despite declines, significant regional national disparities remained, which emphasizes need targeted interventions.

This study aims to examine these trends in S. isolates from Tunisia over two-decade period (2000–2019). Methods: A retrospective time series analysis was conducted on data (n = 4284) gathered eight university hospital centers across Tunisia. Antimicrobial susceptibility testing performed according the European Committee Susceptibility Testing (EUCAST) guidelines. Pneumococcal serotypes were determined subset of samples 2012 2019 903) using multiplex PCR latex agglutination. Results: Penicillin G decreased 9–13.7% during 2000–2002 4.3% by 2019, while amoxicillin increased until reaching 10% 2019. Erythromycin initially before stabilizing between 61.9% 66.3% 2014–2019, whereas tetracycline declined 2000 2008 fluctuated around 40% 2009–2019. Levofloxacin did not exceed 1.2% throughout period.

Antibiotic-Resistant Salmonella in Animal Products Jeopardize Human Health

Food Science of Animal Resources, Год журнала: 2025, Номер 45(2), С. 409 - 428

Опубликована: Фев. 12, 2025

Despite the significance of antibiotics in treating bacterial infections, antibiotic resistance is continuously increasing, thus posing a significant threat. In addition to strains resistant individual drugs, multidrug-resistant (MDR) and pandrug strains, which are all antibiotics, emerging. Salmonella, primary cause global foodborne illness, often transmitted through animal products. Antibiotic treatment crucial for immunocompromised individuals, such as older adults patients with weakened immune systems, due their increased susceptibility severe effects. MDR can arise following use food animals, may transfer humans, leading health challenges. The emergence Salmonella carbapenems, considered last-resort class, particularly concerning. neutralizes mechanisms, horizontal gene via plasmids, efflux/influx system regulation, enzyme production that deactivate or alter antibiotics. rise mega plasmids alarming, it enable broader range This review summarizes current state growing threat underscores urgent need coordinated response.

Inulin, plant polysaccharide, natural functional dietary fibre found in variety plants, including vegetables fruits. Inulin can inhibit pathogenic bacterial growth lowering pH, promote mineral absorption improve intestinal barrier integrity.3. In this study 90 one-day-old chicks were randomly three groups; control (CON) group was fed basic diet; FMT two diets containing 40 ml faecal microbial suspension; INU diet 1.5% inulin suspension.4. Administering the mixed with effectively reduced blood levels IL-1β, IL-4 IL-6, promoted thymus, bursa Fabricius spleen. addition, it enhanced function, increased goblet cells Paneth production, probiotic colonisation butyrate formation inflammation.5. summary, Fabricius, thymus spleen as well facilitated early chick promoting health, reducing inflammation boosting immunity.

Microbiology Spectrum, Год журнала: 2025, Номер unknown

Опубликована: Март 31, 2025

ABSTRACT Streptococcus pneumoniae infection is a leading cause of bacterial pneumonia worldwide, contributing to both invasive pneumococcal diseases and non-invasive diseases. Following the introduction conjugate vaccines (PCV7, PCV10, PCV13), significant decrease in prevalence vaccine-type pneumococci has been observed, while non-vaccine-type (NVT) increased. This shift evident disease incidence nasopharyngeal carriage. Serotype switching refers alteration or exchange serotype-related cps gene locus that flagged globally as serotypes concern. In this study, we collected 166 S . clinical isolates analyzed evaluate vaccine effectiveness. Additionally, identified multidrug-resistant NVT S. recently emerged within epidemic CC876 complex, pandemic serotype 14 clone. More importantly, 15B/ST4749 strain, which might have generated through serotype-switch event from 14/ST4749. Mapping genomic recombination sites progeny revealed donated fragment encompassing cps, pbp1a, additional key factors, including DNA uptake-related comC strain already prevalent, novel possesses potential become global strain. IMPORTANCE The study employed high-throughput sequencing analyze Xiamen Children’s Hospital, China, effectiveness light changes documented occurrence switch (from 15B) between ST4749 observation indicates adaptive response under selective pressure exerted by vaccination, offering insights into strategies for prevention control optimization deployment.

Structure, Function, and Regulation of LytA: The N-Acetylmuramoyl-l-alanine Amidase Driving the “Suicidal Tendencies” of Streptococcus pneumoniae—A Review

Microorganisms, Год журнала: 2025, Номер 13(4), С. 827 - 827

Опубликована: Апрель 5, 2025

Streptococcus pneumoniae (pneumococcus) is a significant human pathogen responsible for range of diseases from mild infections to invasive pneumococcal diseases, particularly affecting children, the elderly, and immunocompromised individuals. Despite conjugate vaccines having reduced disease incidence, challenges persist due serotype diversity, vaccine coverage gaps, antibiotic resistance. This review highlights role LytA, key autolysin (N-acetylmuramoyl-l-alanine amidase), in biology. LytA regulates autolysis, contributes inflammation, biofilm formation, impairs bacterial clearance. It also modulates complement activation, aiding immune evasion. expression influenced by environmental signals genetic regulation tied competence transformation, which an important virulence trait, meningitis. With increase resistance, has emerged as potential therapeutic target. Current research explores its use bacteriolytic therapies, development, synergistic strategies. Various compounds, including synthetic peptides, plant extracts, small molecules, have been investigated their ability trigger LytA-mediated lysis. Future directions include development novel anti-pneumococcal interventions leveraging LytA’s properties while overcoming efficacy resistance-related challenges. Human challenge models animal studies continue deepen our understanding pathogenesis treatment
