Early transmissible ampicillin resistance in zoonotic Salmonella enterica serotype Typhimurium in the late 1950s: a retrospective, whole-genome sequencing study.

Lancet. Infectious Diseases (Print), 2017
BACKGROUND Ampicillin, the first semi-synthetic penicillin active against Enterobacteriaceae, was released onto the market in 1961. The first outbreaks of disease caused by ampicillin-resistant strains of Salmonella enterica serotype Typhimurium were ...

Clinical Efficacy of Sulbactam/Ampicillin in Pediatric Infections Caused by Ampicillin-Resistant or Penicillin-Resistant Organisms

Clinical Infectious Diseases, 1986
Twenty-three children two months to 11 years old were treated with sulbactam/ampicillin or sulbactam/penicillin. Eleven had urinary tract infections (UTI), eight had pus-forming cervical adenitis, and four had lobar pneumonia. Pathogens were isolated from 18 patients: Escherichia coli from 10, Staphylococcus aureus from seven, and Klebsiella pneumoniae

Synergistic action of ampicillin and nafcillin against ampicillin-resistant Haemophilus influenzae [PDF]

Antimicrobial Agents and Chemotherapy, 1980
Six strains of ampicillin-resistant Haemophilus influenzae type b were studied in vitro for synergy between ampicillin and nafcillin. The minimal inhibitory concentrations for these strains with 10(4) colony-forming units per ml were 6.25 to 12.5 microgram of ampicillin per ml and 6.25 to 25 microgram of nafcillin per ml.

Resistance mechanism of Escherichia coli strains with different ampicillin resistance levels

Applied Microbiology and Biotechnology
Antibiotic resistance is an important problem that threatens medical treatment. Differences in the resistance levels of microorganisms cause great difficulties in understanding the mechanisms of antibiotic resistance.

TRAIL‐PEG‐Apt‐PLGA nanosystem as an aptamer‐targeted drug delivery system potential for triple‐negative breast cancer therapy using in vivo mouse model

Molecular Oncology, EarlyView.
Aptamers are used both therapeutically and as targeting agents in cancer treatment. We developed an aptamer‐targeted PLGA–TRAIL nanosystem that exhibited superior therapeutic efficacy in NOD/SCID breast cancer models. This nanosystem represents a novel biotechnological drug candidate for suppressing resistance development in breast cancer.

Non-Susceptibility of Early-Onset Sepsis Pathogens to the Combination of Ampicillin and Gentamicin Among Neonates in Thailand

Antibiotics
Background/Objectives: Empirical antimicrobial therapy for neonatal early-onset sepsis (EOS) comprises ampicillin and gentamicin. However, multidrug-resistant organisms are increasing worldwide, thus inflicting a global burden.
