Phenotypic and genotypic study on antibiotic resistance and pathogenic factors of Staphylococcus aureus isolates from small ruminant mastitis milk in…
2021
Staphyloccoccus aureus is the major cause of mastitis in small ruminants in the Mediterranean farms causing severe losses to dairy industry. Antibiotic treatment has been the most common approach to control these infections. Aim of this study was to investigate antimicrobial resistance (AMR), virulence factors and biofilm-related genes of 84 Sicilian strains of S. aureus isolated from sheep and goats milk during two different periods δT1 (2006-2009) and δT2 (2013-2015). Kirby Bauer method and Polymerase Chain Reaction (PCR) were utilized to monitor AMR and related genes (mecA, tetK, tetM, ermA, ermC). Moreover, toxin genes (tsst-1, sea-see, seg-sej, and sep) and biofilm genes (bap, ica, sas…

E.coli, K.pneumoniae un P. aeruginosa antimikrobiālā rezistence urīnceļu infekcijās
2018
Fons: 2015. gadā PVO ieviesa Globālo mikrobu rezistences uzraudzības sistēmu (GLASS). 2017. gadā to pirmoreiz ieviesa Latvijā. Mērķi: Raksturot pašreizējo situāciju attiecībā uz antimikrobiālo rezistenci, multirezistenci kā arī ESBL (plaša spektra beta laktamāzes) producētājus urīnceļu infekcijām, ko izraisa E. coli, K. pneumoniae un P. aeruginosa un analizēt saistību ar pacienta vecumu, dzimumu un infekcijas izcelsmi. Materiāli un metodes: Kopskaitā tika analizēti 924 urīna paraugi no Paula Stradiņa Klīniskās universitātes slimnīcas, 2016. gadā (731 — E. coli, 147 — K. pneumoniae, 46 — P. aeruginosa). Rezultāti: E. coli rezistences procentuālās daļas: amikacīns: 0,3%, ceftazidīms: 13,8%, c…
Identification and evaluation of antimicrobial resistance of enterococci isolated from raw ewes’ and cows’ milk collected in western Sicily: a prelim…
2019
The present work was carried out to investigate the Antimicrobial Resistance (AMR) of enterococci isolated from raw ewes’ and cows’ milk. The samples were collected from eighteen semi-extensive dairy sheep and cow farms throughout western Sicily. Plate counts, carried out on Rapid Enterococcus Agar commonly used to detect food enterococci, revealed a maximal enterococcal concentration of approximately 4.58 Log Colony Forming Unit (CFU)/mL. Colonies were isolated and differentiated based on genetic analysis by Randomly Amplified Polymorphic DNA (RAPD)-PCR. Thirty-eight different strains were identified. Analysis by a species-specific multiplex PCR assay grouped the strains into three Enteroc…
Sortase A: An ideal target for anti-virulence drug development
2014
Sortase A is a membrane enzyme responsible for the anchoring of surface-exposed proteins to the cell wall envelope of Gram-positive bacteria. As a well-studied member of the sortase subfamily catalysing the cell wall anchoring of important virulence factors to the surface of staphylococci, enterococci and streptococci, sortase A plays a critical role in Gram-positive bacterial pathogenesis. It is thus considered a promising target for the development of new anti-infective drugs that aim to interfere with important Gram-positive virulence mechanisms, such as adhesion to host tissues, evasion of host defences, and bio fi lm formation. The additional properties of sortase A as an enzyme that i…
Adapting to a Global Health Challenge: Managing Antimicrobial Resistance in the Nordics
2020
This article explores the adaptation of Norway and Sweden to one of the major challenges to global public health, antimicrobial resistance (AMR). Guided by assumptions derived from institutional theory, the article investigates whether, and, if so, how the AMR problem has affected the two Nordic countries’ administrative systems and frameworks for Nordic cooperation. The article builds on selected literature, expert interviews, and public documents. The findings suggest that the international impact on Norway and Sweden’s managerial adaptation to AMR is limited. Instead, adaptation takes place through incremental change within existing structures for disease prevention and control and follo…
