Extended-Spectrum β-Lactamases in Human Isolates of Multidrug-Resistant Non-typhoidal Salmonella enterica.

Abstract: A total of 291 non-duplicate isolates of non-typhoidal Salmonella (NTS) were collected from the fecal samples of patients with salmonellosis in Armenia and Georgia during 1996-2016. The isolates were tested for resistance to antimicrobials, including extended-spectrum β-lactamases (ESBL). The high prevalence of multidrug-resistance (MDR) and ESBL-producer phenotypes was detected among Salmonella enterica subsp. enterica serovar Typhimurium (S. Typhimurium) isolates collected from patients in Armenia between 1996 and 2016. A total of 36 MDR NTS isolates were subjected to whole genome sequencing (WGS) to determine the genetic background of antimicrobial resistance (AMR) and mobile genetic elements. All ESBL-producing S. Typhimurium isolates belonged to the same sequence type (ST328). The ESBL-producer phenotype was associated with plasmid-encoded CTX-M-5 production. A range of other plasmids was associated with resistance to other antimicrobials, including the MDR phenotype.

Agrotechnical and energy assessment of strip tillage machine in field conditions

Abstract: The article presents the results of field studies to determine the quality and energy indicators of a modernized cultivator for strip tillage for industrial crops. An experimental setup with load cells with a nominal value of 30000 N is designed to measure the tractive resistance of the cultivator in the field. The result of the study is to establish the relationship between the cultivator traction resistance on the speed movement at various angles of spherical disks attack and the degree of crumbling on the structural and technological parameters of the cultivator. Various structural and technological parameters of the cultivator are the basis for measuring hectare fuel consumption.
