Biological properties of Staphylococcus saprophyticus strains isolated from urinary tract infection and respiratory tract secretions were investigated. The majority of S. saprophyticus strains exhibit moderate surface hydrophobic properties, as measured by Hydrophobic Interaction Chromatography. There was no significant difference between two groups of isolates in respect to electrostatic charge. It was found that the ability to form a diffuse type of growth is characteristic for most of S. saprophyticus strains despite of source of isolation. Five carbohydrates on the surface of 25% of S. saprophyticus strains were shown by means of specific lectin agglutination. Some of the tested strains were capable to bind labelled fibrinogen.

Uropathogens, particularly bacteria, can infect any part of the urinary tract and cause bacteriuria. Our study aimed to examine the antibiotic-resistant profile, associated risk factors, and phenotypic and genotypic features of ESBL, carbapenemase, and mcr resistance genes in multidrug-resistant bacteria. Samples were inoculated on culture media, identified using standard biochemical tests, and species confirmation was performed via 16S rRNA gene amplification.

Objectives: Sheep farming represents an important economic sector in Algeria, and the potential dissemination of methicillin-resistant Staphylococcaceae (MRS) is a critical veterinary and public health concern. This study aimed to determine the prevalence and types of MRS in ovine in Algeria and characterize them using whole-genome sequencing (WGS) analysis.
Methods: Two hundred sheep from 20 different Algerian farms across 3 regions were screened for nasal colonization with MRS.

Monensic acid is a natural polyether ionophore and is a therapeutic of first choice in veterinary medicine for the control of coccidiosis. Although known as a sodium-binding ligand, it can also form a variety of coordination species depending on experimental conditions applied. In this study, we present the crystal structures and properties of Co(II) and Mn(II) complexes of sodium monensinate (MonNa) derived from the reaction of MonNa with cobalt or manganese dinitrates.

The escalating incidence of hospital infections due to antibiotic resistance necessitates the identification of alternative therapeutic agents such as probiotics. This study was designed to isolate and evaluate the efficacy of probiotics against , a prevalent etiological agent of urinary tract infections (UTIs). A total of 100 strains were isolated from clinical samples and subjected to antibiotic susceptibility testing via the disc diffusion method.
