Evaluation of the double-zone hemolysis (DZH) test for the detection of livestock-associated methicillin-resistant .

Unlabelled: Livestock-associated methicillin-resistant (LA-MRSA), such as clonal-complex (CC)398, are of clinical relevance due to their multi-drug resistance profiles, adding to the overall burden of MRSA in humans. The objective was to evaluate the double-zone hemolysis (DZH) test as a simple and reliable method for detecting LA-MRSA in the clinical microbiology laboratory. isolates assigned to CC398 ( = 183; 152 MRSA/31 methicillin-susceptible [MSSA]), CC1 ( = 44; MRSA), and other CCs ( = 144; 94 MRSA/50 MSSA) were investigated.

Utilization and Findings of Flexible Naso-Pharyngo-Laryngoscopy in Upper Airway Disorders: A Clinic Audit.

Background: Flexible naso-pharyngo-laryngoscopy (NPL) has become an essential clinic tool for evaluating patients with upper airway disorders in otorhinolaryngology. It has been established to be a simple, cost-effective, and minimally invasive technique with good diagnostic yields. This study aimed to audit the procedure of flexible NPL done in our clinic over 2 years and analyse the technique, indications, and findings of the procedure.

Unexpected role of pig nostrils in the clonal and plasmidic dissemination of extended-spectrum beta-lactamase-producing Escherichia coli at farm level.

The presence of methicillin-resistant or -susceptible S. aureus in pig nostrils has been known for a long time, but the occurrence of extended-spectrum beta-lactamase (ESBL)-producing E. coli has hardly been investigated.

Beyond the Wild MRSA: Genetic Features and Phylogenomic Review of -Mediated Methicillin Resistance in Non- Staphylococci and Mammaliicocci.

Methicillin resistance, mediated by the gene in staphylococci and mammaliicocci, has caused tremendous setbacks in the use of antibiotics in human and veterinary medicine due to its high potential of presenting the multidrug resistance (MDR) phenotype. Three other analogs exist, of which the has evolutionary been associated with methicillin-resistant (MRSA) in wild animals, thus loosely referred to as the wild MRSA. In this study, we present an epidemiological review and genomic analysis of non- staphylococci and mammaliicocci that carry the -mediated methicillin resistance trait and determine whether this trait has any relevant link with the One Health niches.

Comparative genomics of Staphylococcus aureus strains from wild birds and pig farms elucidates levels of mobilomes, antibiotic pressure and host adaptation.

Objectives: This study characterized the resistome, mobilome and phylogenomic relatedness of Staphylococcus aureus strains previously obtained from healthy nestling storks (HNS), pigs (HP) and pig farmers (HPF) to analyse possible transmission pathways of S. aureus with implications for the spread of antimicrobial resistance.

Methods: The genomic contents of 52 S.

Nasal staphylococci microbiota and resistome in healthy adults in La Rioja, northern Spain: High frequency of toxigenic S. aureus and MSSA-CC398 subclade.

This study determined the nasal staphylococci diversity and characterized their resistome, with a focus on the mobilome of methicillin-susceptible Staphylococcus aureus (MSSA)-CC398 subclade from healthy adults in La Rioja (northern Spain). Nasal staphylococci recovered from 57 healthy individuals (HI) were identified (MALDI-TOF-MS) and their antimicrobial resistance, virulence determinants and genetic lineages were studied. The relatedness of MSSA-CC398 isolates was assessed by core-genome single-nucleotide-polymorphisms (SNPs).

Within-Host Diversity of Coagulase-Negative Staphylococci Resistome from Healthy Pigs and Pig Farmers, with the Detection of Carrying Strains and MDR-.

The ecology and diversity of resistome in coagulase-negative staphylococci (CoNS) from healthy pigs and pig farmers are rarely available as most studies focused on the livestock-associated methicillin-resistant . This study aims to characterize the antimicrobial resistance (AMR) mechanisms, intra-host species diversity (more than one species in a host), and intra-species AMR diversity (same species with more than one AMR profile) in CoNS recovered from the nasal cavities of healthy pigs and pig farmers. One-hundred-and-one CoNS strains previously recovered from 40 pigs and 10 pig farmers from four Spanish pig farms were tested to determine their AMR profiles.

Antimicrobial resistome of coagulase-negative staphylococci from nasotracheal cavities of nestlings of Ciconia ciconia in Southern Spain: Detection of mecC-SCCmec type-XI-carrying S. lentus.

The antimicrobial resistance (AMR) genes of 268 non-duplicated coagulase-negative staphylococci (CoNS) previously obtained from nasotracheal cavities of nestling storks were characterized. They included S. sciuri isolates (n = 191), and non-sciuri-CoNS isolates (NSc-CoNS, n = 77).

Nasal staphylococci community of healthy pigs and pig-farmers in Aragon (Spain). Predominance and within-host resistome diversity in MRSA-CC398 and MSSA-CC9 lineages.

This study investigated the diversity and carriage rate of nasal spp., and within-host variability of antimicrobial resistance (AMR), virulence determinants, immune evasion cluster (IEC) types and genetic lineages of isolates. Also, the co-carriage rate of CoNS with in the same nasal niche of healthy pigs and pig-farmers were studied in four pig-farms (A-D) in Aragon (Spain).

Nasotracheal Microbiota of Nestlings of Parent White storks with Different Foraging Habits in Spain.

Migratory storks could be vectors of transmission of bacteria of public health concern mediated by the colonization, persistence and excretion of such bacteria. This study aims to determine genera/species diversity, prevalence, and co-colonization indices of bacteria obtained from tracheal (T) and nasal (N) samples from storks in relation to exposure to point sources through foraging. One-hundred and thirty-six samples from 87 nestlings of colonies of parent white storks with different foraging habits (natural habitat and landfills) were obtained (84 T-samples and 52 N-samples) and processed.

Staphylococcus aureus Carriage in the Nasotracheal Cavities of White Stork Nestlings (Ciconia ciconia) in Spain: Genetic Diversity, Resistomes and Virulence Factors.

The molecular ecology of Staphylococcus aureus in migratory birds (such as white storks) is necessary to understand their relevance in the "One Health" ecosystems. This study determined the nasotracheal carriage rates of S. aureus from white storks in Southern Spain and genetically characterized the within-host diversity.

This study determined the carriage rates and antimicrobial resistance (AMR) genes of enterococci from nasotracheal samples of three healthy animal species and in-contact humans. Nasal samples were collected from 27 dog-owning households (34 dogs, 41 humans) and 4 pig-farms (40 pigs, 10 pig-farmers), and they were processed for enterococci recovery (MALDI-TOF-MS identification). Also, a collection of 144 enterococci previously recovered of tracheal/nasal samples from 87 white stork nestlings were characterized.
