Interaction of primary mast cells with Borrelia burgdorferi (sensu stricto): role in transmission and dissemination in C57BL/6 mice

Parasites & Vectors, 2017
Background Borrelia burgdorferi (sensu lato), the causative agent of Lyme borreliosis is a bacterium transmitted by hard ticks, Ixodes spp. Bacteria are injected into the host skin during the tick blood meal with tick saliva.

Genome‐Wide Codon Reprogramming Enables a Multifactorially Attenuated Influenza Vaccine with Broad Cross‐Protection

Advanced Science, EarlyView.
Genome‐wide codon reprogramming of influenza A virus introduces 1956 synonymous mutations across five segments and elevates CpG content, causing defective NA packaging, loss of NS1 accumulation, and enhanced ZAP‐mediated antiviral responses without affecting RNA or protein synthesis. These mechanisms result in profound attenuation and potent homologous

Methicillin-resistant and methicillin-susceptible Staphylococcus aureus in French hedgehogs admitted to a wildlife health center

One Health
The mecC gene conferring methicillin-resistance has always been found on a SCCmec type XI element and is largely restricted to the few clonal complexes CC130, CC1943, CC425, CC49 and CC599.

Photothermal–Immunomodulatory Hydrogel Reinforced by Ti3C2/ZnAl‐LDH Nanoplatform for Eradicating MRSA and Promoting Diabetic Wound Healing

Advanced Science, EarlyView.
A NETs‐inspired Ti3C2/LDH hydrogel integrates trapping, ROS boosting, and M2‐immunomodulation for MRSA‐infected wound repair. ABSTRACT MRSA infections give rise to chronic cutaneous and advance into profound tissue invasions, including osteomyelitis and sepsis—conditions for which existing clinical interventions offer only limited efficacy. The utility

Synthetic Lethal Therapy Based on Dimorphism for Systemic Infection of Drug‐Resistant Candida albicans

Advanced Science, EarlyView.
To tackle the alarming mortality rate linked to Candida albicans infections, a synthetic lethal strategy precisely aimed at the two distinct forms of this fungus: yeast and hyphae is formulated. Ultimately, through the innovative use of macrophage membranes for drug delivery, the effectiveness of this strategy is substantially boosted while ...

NIR Light‐Driven Photocatalytic Antibacterial Hydrogels for Synergistic MRSA Biofilm Eradication and Wound Regeneration

Advanced Science, EarlyView.
The nanohybrid hydrogel (Fe‐BOS@C/H Gel) is composed of Fe‐Bi2O2‐XS (Fe‐BOS) photocatalysts and CS‐ADH/OHA (C/H) hydrogel. Fe‐BOS photocatalysts achieve near‐infrared (NIR) light‐driven antibacterial photocatalytic/mild photothermal therapy (APCT/MPTT), effectively eliminating methicillin‐resistant Staphylococcus aureus (MRSA) biofilms. The degradation

Pan2‐Pan3 Complex‐Mediated Deadenylation Enforces mRNA Quality Control for Infection of the Rice Blast Fungus

Advanced Science, EarlyView.
Discovery that deadenylation, rather than transcription, acts as the rate‐limiting step for developmental timing in a plant pathogen. Evidence that P‐body integrity and mRNA decay are mechanistically coupled to rapid cellular differentiation under environmental stress. Identification of Pan2‐Pan3 as a pathogen‐specific “meta‐virulence factor” absent in

Methicillin-Resistant S. aureus Carrying the PVL and Toxic Shock Syndrome Toxin in Healthy Dogs in Algeria

Antibiotics
Background/Objectives: Staphylococcus aureus and Staphylococcus pseudintermedius are major opportunistic pathogens in both humans and dogs. In pets, the dissemination of methicillin-resistant isolates (MRSA or MRSP) is problematic for the treatment of ...

The health significance of heterotrophic bacteria in drinking water [PDF]

, 1997
Tap water is not sterile; it contains organisms which grow in water distribution systems or inside taps and their fittings. The absence of known pathogenic bacteria is assured by the absence of the indicator organisms but concerns have been raised in the

Virulence and Metabolism

Microbiology Spectrum, 2019
ABSTRACT Staphylococcus aureus is clearly the most pathogenic member of the Staphylococcaceae . This is in large part due to the acquisition of an impressive arsenal of virulence factors that are coordinately regulated by a series of dedicated transcription factors.
