D 7). There was no spatial autocorrelation among web pages for the amount of adult and nymphal ticks sampled (Moran’s I p-value = 0.11), percentage of adults (Moran’s I p-value = 0.85), abundance (Moran’s I p-value = 0.23), species richness (Moran’s I p-value = 0.46), and Shannon diversity index (Moran’s I p-value = 0.64). Beta diversity indices from the Sorensen matrix of dissimilarity involving the seven web sites had been high (mean = 0.81, typical deviation = 0.16) indicating that the web pages had fairly distinctive communities (Table four). Websites 2 and three were by far the most equivalent (index of dissimilarity = 0.43), sharing the 2 most abundant species identified, S. xylosus and M. micrococcus. Web site 6 was the less equivalent web page, specially resulting from the presence of a single identified isolate: S. epidermidis.Table 4. Sorensen matrix of dissimilarity.

Antibiotic Resistance Pattern and Genomic Traits of C. davisae One bacterium was isolated both in selective and non-selective media, evidencing an intrinsic resistance to numerous antibiotics, C. davisae. Its bacterial identification was confirmed by MALDI-TOF MS, 16S rRNA sequencing and WGS. The phenotypic resistance profile of this C. davisae strain was characterized via MIC determination for 20 antimicrobials (Table 5). Phenotypic resistance was observed with cefoxitin (MIC of 16 /mL), ampicillin (MIC of 64 /mL) and colistin (MIC of 16 /mL). To get insight in to the molecular features underlying the antimicrobial resistance pattern, WGS information have been made use of to identify orthologs of resistance pathways in KAAS. Within the antimicrobial resistance genes categories, four gene sets were identified: (i) -Lactam resistance, (ii) vancomycin resistance, (iii) cationic antimicrobial peptide (CAMP) resistance, which includes the LPS modification technique linked with colistin resistance, and (iv) a miscellanea of genes implicated in multidrug resistance phenotype (full list given in Supplementary Table S2). In this strain, ampicillin resistance is mediated by genes on the mec family, the bla systemInt. J. Environ. Res. Public Health 2021, 18,9 ofand the ParR/ParS, CusR/CusS two-component systems. Colistin resistance is connected with lipopolysaccharide (LPS) modification by way of cationic substitution as the PhoQ/PhoP two-component method is involved. No mcr genes (1 to ten) have been discovered excluding the Sutezolid Epigenetic Reader Domain possibility of acquisition of colistin resistance by means of horizontal gene transfer.Table five.
