A Pilot Study on the Prevalence and Characterization of Multidrug‐Resistant Gram‐Negative Bacteria in Chicken and Pork Meat Around Kathmandu District, Nepal

open access: yesMicrobiologyOpen, Volume 15, Issue 2, April 2026.
This study investigated multidrug resistance in Gram‐negative bacteria from chicken and pork meat in Kathmandu, isolating 136 strains from 13 samples. Nearly half were multidrug resistant, highlighting contaminated meat as a potential route for zoonotic transmission and the need for antimicrobial resistance monitoring in Nepal.

Antioxidant and Antibacterial Activities of Secondary Metabolites Produced by Streptomyces Isolates Against Extended‐Spectrum β‐Lactamase‐Producing Bacteria

open access: yesMicrobiologyOpen, Volume 15, Issue 2, April 2026.
soil‐derived Streptomyces sp. SM7 with bactericidal and antioxidant activities ABSTRACT Extended‐spectrum β‐lactamase (ESBL)–producing Gram‐negative bacteria pose a severe therapeutic challenge globally. Streptomyces remain one of the most prolific natural sources of antibacterial and antioxidant secondary metabolites, yet their activity against ESBL ...

Using Selective Agar Containing Ciprofloxacin and Tetracycline Reveals Resistant Oral Microbiota in Healthy and Periodontitis Patients

open access: yesMicrobiologyOpen, Volume 15, Issue 2, April 2026.
Oral biofilms from healthy and periodontitis patients harbor diverse bacteria, including aerobes and obligate anaerobes. Using selective media with tetracycline or ciprofloxacin, 495 strains (106 species) were isolated. Resistance was common—32.9% to ciprofloxacin, 15.2% to tetracycline, 0.6% to ampicillin—highlighting the oral cavity as a reservoir ...

Non‐redox Lewis Acids Supported Pd‐Catalyzed C—C /C—H Activation and Accession to Produce Pharmaceutical Intermediates

open access: yesChemistryOpen, Volume 15, Issue 4, April 2026.
Palladium is a simple and versatile redox‐active metal that plays a crucial role in the oxidation reactions for organic synthesis and production of pharmaceutical intermediates. Notably, there has been significant progress with Lewis acids (LAs), which are non‐redox metal ions promoting Pd(II)‐catalyzed oxidation via C—H and C—C bond activation.

Global Analysis of the Co‐Occurrence of Antimicrobial and Metal Resistance Genes in Bacterial Genomes From Dairy‐Isolated Pathogens

open access: yesEnvironmental Microbiology, Volume 28, Issue 4, April 2026.
Metal contamination in dairy systems drives antibiotic resistance through co‐selection. Analysis of 3303 genomes revealed 74% of isolates harbour more metal than AMR genes. Arsenic (arsB) and tetracycline (tet(38)) resistance co‐occur in 43% of bacteria, exhibiting nearly identical prevalence, suggesting a tight genetic linkage.

Transmisssion Dynamics of Enterococcus spp. Throughout the Heliconius erato phyllis (Lepidoptera; Nymphalidae) Life Cycle

open access: yesEnvironmental Microbiology Reports, Volume 18, Issue 2, April 2026.
Enterococcus spp. dominate the gut microbiota of Heliconius erato phyllis, transmitted horizontally via host plants (Passiflora suberosa) and persisting through development. Multidrug‐resistant strains were found in larvae and plants, suggesting environmental reservoirs of antimicrobial resistance. This study reveals key microbial transmission dynamics
