“…The resistance of staphylococci to these β-lactams antibiotics may be attributed to the production of β-lactamase, an enzyme that inactivates penicillin and closely related antibiotics and this may be probably explained by a horizontal transfer of antibiotic resistance gene from the resistant bacterium to another bacterium normally susceptible to this antibiotic. Moreover, this could be associated with the predominant use of penicillin for treatment of animal diseases; this result agrees with other results regarding the increase in incidence of β-lactam antibiotics resistance (Schwarz et al, 1998;Alekshun and Levy, 2000). A high incidence of antimicrobial resistance among coagulase-negative staphylococci was also reported by Mártonová et al (2008).…”

This study was conducted during a six months period (March to August 2008) at the Veterinary laboratory, Department of Animal Resources, Doha, Qatar to determine the incidence of different bacterial genera farm animals in particular the occurrence of Staphylococcus species. The samples were from the rectum, milk, feces, nasal, swab of vagina, cloacal -uterin, intestine, liver and pus. Samples were collected from various animals of different regions. A total 318 of 429 samples gave positive results for Gram-negative and Gram-positive bacteria and 90 cultures were identified as Staphylococcus. The highest isolates were from camels' milk and none were obtained from specimens of cats and horses. A total of 33 selected Staphylococcus isolates were identified to species level and the most common isolated was coagulase-positive S. aureus (14), followed by coagulase-negative, S. lentus (10), S. xylosus (5), S. sciuri (2), S. lugdunensis (1) and S. caprae (1). The antimicrobial susceptibility profiles of these were determined using cephalothin, gentamycin, neomycin, ampicillin, norfloxacin, penicillin, tetracycline and a combination of trimethoprim and sulphamethoxazole. All identified species were sensitive to cephalothin except one strain of S. aureus. Most of the isolates showed multiple antimicrobial resistance profiles.

“…To date, four different tetracycline resistance (tet) genes assigned to classes K, L, M, and O of bacterial tet genes have been detected in staphylococci of animal origin [91].…”

“…The tet(K) genes are commonly located on small multicopy plasmids of 4.3 to 4.7 kbp which are structurally closely related and do not harbour additional resistance genes [25,68,72,78,84,91]. The prototype tet(K)-encoding plasmid is the 4.45 kbp plasmid pT181 from human S. aureus [40].…”

“…The prototype tet(K)-encoding plasmid is the 4.45 kbp plasmid pT181 from human S. aureus [40]. Plasmids indistinguishable from or closely related to pT181 have been detected in virtually all staphylococcal species of animal origin [25,68,72,78,84,91,105]. In rare cases pT181-like plasmids have also been detected as IS257-flanked integrates in the chromosome of S. aureus or as parts of large staphylococcal plasmids [105].…”

“…Their presence in staphylococci seems to be limited to a few staphylococcal species of animal origin, such as S. aureus, S. hyicus, S. lentus, S. sciuri, and S. xylosus [91]. The tet(L) genes were mainly found on plasmids that varied in size between 4.3 and 11.5 kbp [78,87,89].…”

-Besides their role as commensals on the skin and mucosal surfaces, staphylococci may be involved in a wide variety of diseases in animals. Staphylococcal infections in animals are mainly treated with antimicrobial agents and as a consequence, staphylococci from animal sources have developed and/or acquired resistance to the respective antimicrobial agents. Resistance statistics obtained from national monitoring programmes on staphylococci from cattle and pigs, but also from surveillance studies on staphylococci involved in diseases in dogs are reported and reviewed with regard to their comparability. This review mainly focusses on the genetic basis of antimicrobial resistance in staphylococci of animal origin. Particular attention is paid to resistance to those antimicrobial agents which are most frequently used in veterinary medicine, but also to antimicrobial agents, such as chloramphenicol and mupirocin, which are used in specific cases for the control of staphylococcal infections in pets and companion animals. In addition, plasmids and transposons associated with the respective resistance properties and their ways of spreading between members of the same or different staphylococcal species, but also between staphylococci and other gram-positive bacteria, are described.antimicrobial resistance / Staphylococcus / animal origin / epidemiology / horizontal gene transfer Vet.

Synergistic SERS Enhancement in GaN‐Ag Hybrid System toward Label‐Free and Multiplexed Detection of Antibiotics in Aqueous Solutions

et al. 2021

Noble metal-based surface-enhanced Raman spectroscopy (SERS) has enabled the simple and efficient detection of trace-amount molecules via significant electromagnetic enhancements at hot spots. However, the small Raman cross-section of various analytes forces the use of a Raman reporter for specific surface functionalization, which is time-consuming and limited to low-molecular-weight analytes. To tackle these issues, a hybrid SERS substrate utilizing Ag as plasmonic structures and GaN as charge transfer enhancement centers is presented. By the conformal printing of Ag nanowires onto GaN nanopillars, a highly sensitive SERS substrate with excellent uniformity can be fabricated. As a result, remarkable SERS performance with a substrate enhancement factor of 1.4 × 10 11 at 10 fM for rhodamine 6G molecules with minimal spot variations can be realized. Furthermore, quantification and multiplexing capabilities without surface treatments are demonstrated by detecting harmful antibiotics in aqueous solutions. This work paves the way for the development of a highly sensitive SERS substrate by constructing complex metal-semiconductor architectures.
