Fifty patients suffering from infections caused by various salmonella species were treated with trimethoprim-sulphamethoxazole compound. Twenty-three had enteric fever and two were biliary carriers of Salmonella typhi. The other 25 suffered from infections caused by salmonella species other than S. typhi or S. paratyphi B. Twenty-one of the patients with enteric fever responded clinically to the drug, one failed treatment, and one died. Two patients suffering from typhoid fever relapsed and three temporarily excreted S. typhi in stools following treatment. One of the typhoid carriers was successfully treated. All patients with infections caused by salmonella species other than S. typhi or S. paratyphi B responded to treatment but 17 continued to excrete the organism in their stools after the course of trimethoprim-sulphamethoxazole compound. Four patients developed rashes during therapy and two became anaemic.

To analyze the genus, drug resistance/virulence and phylogenetic characteristics of strains isolated from brucellosis surveillance sentinels in Henan Province from 2013 to 2022, and provide baseline data for the surveillance, early warning and outbreak tracing of brucellosis. Blood samples were collected from patients with infection for strain isolation, culture and species identification, drug susceptibility test, whole genome sequencing, splicing and assembly, functional/virulence/resistance gene prediction analysis and phylogenetic tree drawing based on single nucleotide polymorphism (SNP). In 36 brucellosis patients, the majority were men (86.

The presence of antibiotics in seafood for human consumption may pose a risk for consumers. Furthermore, some marine organisms, such as mussels, can result in appropriate bioindicators of marine contamination. In this work, a multiresidue analytical methodology suitable for the determination of antibiotics and metabolites in mussels is proposed.

This study assesses the concentrations of a range of antibiotics in riverine and transitional sediments in Ireland. A selection of 12 macrolide, fluoroquinolone, sulphonamide, and diaminopyrimidine antibiotics were quantified in 80 grab surficial sediment samples from around Ireland, selected to investigate areas of potentially higher pollution risk (agriculture, aquaculture, industrial emissions, and wastewater emission points) as well as isolated areas where there are no known pollution sources. Several of the macrolides and sulphonamides/trimethoprim were generally detected more frequently above limits of quantification (LoQ).

The increasing consumption of medicines and the lack of efficient technologies in wastewater treatment plants (WWTPs) can release pharmaceutically active compounds (PhACs) into any given river with the subsequent risk to the environment and human health. To assess the occurrence and transfer pathways of PhACs through the river ecosystem, 22 PhACs and one metabolite were analyzed in WWTPs, river sediments and fish collected alongside the Tagus River basin between 2020 and 2022. All the matrices presented at least two drugs being azithromycin the only one quantified in all of them.

Colibacillosis caused by avian pathogenic (APEC) is causing economic losses to the global poultry industry. Increased prevalence of antibiotic resistance in APEC is the leading cause for increased indiscriminate use of various antimicrobial compounds in farms. The study aimed to investigate the presence of phenotypic and genotypic markers for antibiotic resistance, metals, and biocides in APEC from Bangladeshi poultry and details about the antimicrobials used in poultry farms.
