Authors: Jiménez Velásquez SDC, Torres Higuera LD, Parra Arango JL, Rodríguez Bautista JL, García Castro FE, Patiño Burbano RE Abstract Staphylococcus spp. is one of the pathogens that cause bovine mastitis and may present multiple resistance to different antimicrobial groups. The aim of this study was to phenotypically identify Staphylococcus spp. isolates obtained from bovine milk and to characterize their antimicrobial resistance profile. The 101 strains were classified by phenotypic tests, their resistance to oxacillin, cefoxitin, penicillin, ampicillin, tetracycline, kanamyci...
ConclusionTo our knowledge, this is the first report on complete nucleotide sequences of type 2 IncC plasmids. These findings, which hypothesise the acquisition of KPC-2-encoding transposon Tn4401a by an IncC replicon, indicate the ongoing need for molecular surveillance studies of multidrug-resistant pathogens. In addition, they underline the increasing clinical importance of the IncC plasmid family.

ConclusionMultidrug resistance was higher among HLGR and HLSR isolates compared to non-HLGR and non-HLSR isolates which is a concern because it results in limitation of treatment choices. More than 50% of the isolates were sensitive to aminoglycosides; hence correct identification in clinical laboratories and administration of these antibiotics can result in decrease of antibiotics such as Vancomycin and Linezolid and help to reduce the emergence of resistance to these drugs.
ConclusionsIn conclusion, it would appear that the most prevalent mcr gene of E. coli from diarrheic weaned piglets in Korea was mcr-3. And, to our best knowledge, this is the first report for coexistence of two plasmid-mediated colistin resistance genes, mcr-1 and mcr-3 in the same isolates (0258, 0491, 0516) from piglets with diarrhea in Korea. Those mcr–positive isolates showed multi-drug resistance, and majority of those encoded Stx2e and F18. This indicates that the risk of inefficient treatment for edema disease in weaned piglets.

Conclusion: Our results show a substantial increase in the direct medical costs of patients with urinary tract infections caused by beta-lactam-resistant Gram-negative bacilli (cephalosporins and carbapenems). This situation is of particular concern in endemic countries such as Colombia, where the high frequencies of urinary tract infections and the resistance to beta-lactam antibiotics can generate a greater economic impact on the health sector.

Acinetobacter baumannii is one of the most important nosocomial pathogens distributed worldwide. Due to its multidrug-resistance and the propensity for the epidemic spread, the World Health Organization includes this bacterium as a priority health issue for development of new antibiotics. The aims of this study were to investigate the antimicrobial resistance profile, the clonal relatedness, the virulence profiles, the innate host immune response and the clonal dissemination of A. baumannii in Hospital Civil de Guadalajara (HCG), Hospital Regional General Ignacio Zaragoza (HRGIZ) and Pediatric ward of the Hospital General ...
