Hui Pan, William Ba-Thein
Global Pharma Health Fund (GPHF) Minilab™, a semi-quantitative thin-layer chromatography (TLC)-based commercially available test kit, is widely used in drug quality surveillance globally, but its diagnostic accuracy is unclear. We investigated the diagnostic accuracy of minilab system for antimicrobials, using high-performance liquid chromatography (HPLC) as reference standard. Following the Minilab protocols and the Pharmacopoeia of the People's Republic of China protocols, Minilab-TLC and HPLC were used to test five common antimicrobials (506 batches) for relative concentration of active pharmaceutical ingredients...

Fourteen new organotin(IV) carboxylate complexes with peptide linkage of (2-(4-methoxy-2-nitrophenylcarbamoyl)benzoic acid) were successfully synthesized and characterized by elemental analyses, FT-IR, NMR ((1)H, (13)C and (119)Sn) and single crystal X-ray techniques. FT-IR results of the sodium salt of 2-(4-methoxy-2-nitrophenylcarbamoyl)benzoic acid and complexes showed that the coordination took place via oxygen atoms of the carboxylate group. (1)J((119)Sn-(13)C), (2)J((119)Sn-(1)H) and θ values calculated from (1)H and (13)C NMR data using Lockhart's equation reveal a trigonal bipyramidal geometry for triorganotin(IV) derivatives and an octahedral geometry for diorganotin(IV) derivatives...

Antimicrobial resistance (AMR) among bacteria isolated from food-producing animals is a growing concern with implications for public health. AMR surveillance is essential to identify resistance trends and help in the design of effective and efficient control strategies. The aim of the study was to describe the antimicrobial susceptibility of pathogenic Escherichia coli isolated from three livestock productions in France (cattle, swine and poultry). The trend in resistance to the most commonly prescribed antibiotics in animal health was analysed as follows: amoxicillin (penicillin), spectinomycin or streptomycin (aminoglycoside), tetracycline and trimethoprim-sulfamethoxazole/Enrofloxacin and ceftiofur were also taken into account as members of critically important antimicrobial families in human and veterinary medicine, that is fluoroquinolones and third-generation cephalosporins, respectively...

Spontaneous bacterial peritonitis (SBP) is the most common infection in end-stage liver disease patients. SBP is defined as an ascitic fluid infection with a polymorphonuclear leucocyte count ≥ 250/mm(3) without an evident intra-abdominal surgically treatable source. Several mechanisms contribute to SBP occurrence, including translocation of gut bacteria and their products, reduced intestinal motility provoking bacterial overgrowth, alteration of the gut's barrier function and local immune responses. Historically, Gram-negative enteric bacteria have been the main causative agents of SBP, thereby guiding the empirical therapeutic choice...
