ABSTRACT Background Preirradiated patients undergoing microvascular head and neck reconstruction for tumor recurrence or osteoradionecrosis (ORN) face surgical site infection (SSI) rates exceeding 30%. The impact of perioperative extended‐spectrum antibiotic coverage remains unclear. This study hypothesizes that calculated prophylaxis with piperacillin/

Structural shifts in TolC facilitate Efflux-Mediated β-lactam resistance
Efflux-mediated β-lactam resistance is a major public health concern, reducing the effectiveness of β-lactam antibiotics against many bacteria. Structural analyses show the efflux protein TolC in Gram-negative bacteria acts as a channel for antibiotics ...

The effect of combined sewer overflows on the abundance of antibiotic resistance genes and bacteria in the James River [PDF]
Antibiotic resistance is a major threat to human health. Clinical situations are the main focus for antibiotic resistance research, but understanding the spread of resistance in the environment is also vital.

Transfer of antibiotic resistance in Staphylococcus aureus [PDF]
Staphylococcus aureus is a serious human pathogen with remarkable adaptive powers. Antibiotic-resistant clones rapidly emerge mainly by acquisition of antibiotic-resistance genes from other S. aureus strains or even from other genera.

Antibiotic Remodeling of the Gut Microbiota Impairs Host Resistance to Secondary Infection
Gut microbial dynamics induced by four antibiotics, revealed distinct taxonomic and functional shifts. Vancomycin‐perturbed bacteriomes were proven to promote pathogen resistance to antibiotic treatment. Metronidazole‐treated mice showed pronounced Salmonella translocation to hepatic tissue, and altered Enterococcus avium populations modulated host ...

Synthetic Lethality Reveals Mechanisms of
Most β-lactam antibiotics are ineffective against Mycobacterium tuberculosis due to the microbe’s innate resistance. The emergence of multidrug-resistant (MDR) and extensively drug-resistant (XDR) strains has prompted interest to repurpose this class of ...

Methicillin-resistant Staphylococcus aureus (MRSA) ST398 associated with clinical and subclinical mastitis in Belgian cows [PDF]
Methicillin-resistant Staphylococcus aureus (MRSA) is infrequently reported in mastitis. Yet, as in many other countries, the prevalence of methicillin resistance among S. aureus from mastitis is currently unknown in Belgium.

ABSTRACT Surgical antibiotic prophylaxis (SAP) is crucial in preventing postoperative surgical site infections (SSIs), especially in clean and clean‐contaminated surgeries. It was a prospective comparative observational study that compared the effectiveness and safety of single‐dose ceftriaxone monotherapy with amoxicillin–clavulanic acid as a ...

Optimizing Guideline-Recommended Antibiotic Doses for Pediatric Infective Endocarditis [PDF]
The American Heart Association recently published an updated scientific statement on the management of infective endocarditis in childhood. The recommendations included for vancomycin, aminoglycoside, and β-lactam dosing and monitoring are based ...
