Profile of antimicrobial resistance in isolates of Staphylococcus spp. obtained from bovine milk in Colombia.

[Profile of antimicrobial resistance in isolates of Staphylococcus spp. obtained from bovine milk in Colombia]. Rev Argent Microbiol. 2019 Sep 16;: 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, kanamycin, sulfamethoxazole / trimethoprim, clindamycin and erythromycin was determined by the Kirby-Bauer technique and the presence of resistance genes by PCR. A total of 65 strains was S. aureus and 36 strains were coagulase-negative staphylococci (CoNS). We found different patterns of resistance to antibiotics evaluated in strains of S. aureus and CoNS, only the resistance to ampicillin was found associated with the species (p

Abstract Mastitis caused by multi- or pan-drug resistant bacteria is a growing health concern. A total of 110 milk samples were collected: Staphylococcus aureus, Streptococcus agalactiae, Streptococcus dysgalactiae, Enterococcus faecalis, and Escherichia coli were present in 54/110 (49.09%), 37/110 (33.63%), 25/110 (22.72%), 7/110 (6.36%), and 50/110 (45.45%) samples, respectively. A total of 20 methicillin-resistant S. aureus (MRSA) isolates, 19 Streptococcus sp. isolates, and 15 E. coli isolates were selected, and 100% were positive for (coagulase and hemolysins), streptokinase, and hemolytic activity, respectiv...

This study demonstrated the circulation of diverse clones of S. aureus among dairy animals in Iran, with a different clonal composition between cows and small ruminants. The current study also reports MRSA-related mastitis in dairy cows, emphasizing the need for comprehensive surveillance. PMID: 31501949 [PubMed - as supplied by publisher]

Needle aspiration was performed and the culture was positive for N. gonorrhoeae. She was successfully treated with intravenous ceftriaxone and transitioned to oral ciprofloxacin once susceptibilities were known.N. gonorrhoeae is an uncommon cause of nonlactational...

hez J Abstract The primary objective of this study was to explore the variability of Streptococcus uberis (S. uberis) isolates by extracting multilocus sequence typing (MLST) data from whole-genome sequencing. The secondary objective was to determine the distribution of the phenotypic antimicrobial resistance (AMR) and the associated AMR genes as well as the virulence gene profiles among sequence types (STs). Sixty-two isolates were recovered from 16 herds in 3 Canadian Maritime Provinces: New Brunswick (14.5%), Nova Scotia (48.3%), and Prince Edward Island (37.1%). Of these, 9, 30, and 23 were recovered from post...

In this study, we evaluated the antimicrobial activity of the extracts from herbal plant Persicaria pensylvanica’s flower, leaf, stem, and root. This plant is also known by a common name Pennsylvania smartweed. The antimicrobial effect of the extracts was tested using minimum inhibitory concentration (MIC) and minimum bacteriocidal concentration (MBC) methods in comparison with tetracycline, a commercial antibiotic.ResultsWe found that extract from P. pensylvanica kills bovine mammary glands pathogenic S. aureus strain Newbould 305.
