“…The frequency of ESBL-producing Enterobacteriaceae reported in this study (3.3%) agrees with other studies conducted in bulk-tank milk samples in Switzerland, Brazil, India, the Czech Republic, Indonesia, and Germany, which reported prevalences ranging between 0 and 9% (Geser et al, 2012;Nóbrega et al, 2013;Rasheed et al, 2014;Skočková et al, 2015;Sudarwanto et al, 2015;Odenthal et al, 2016).…”

“…Our isolates contrast with the predominant isolates in dairy farms from other areas where E. coli and K. pneumoniae have been most frequently reported (Locatelli et al, 2010;Dahmen et al, 2013;Sudarwanto et al, 2015;Odenthal et al, 2016). However, the relevance of other bacteria of the Enterobacteriaceae family could be underestimated because studies have mainly focused on E. coli and K. pneumoniae (Smet et al, 2010;Schmid et al, 2013;Sudarwanto et al, 2015;Odenthal et al, 2016).…”

“…Recently, studies of the characteristics and prevalence of ESBL-producing Enterobacteriaceae in animals have increased in different countries worldwide (Smet et al, 2010;Timofte et al, 2014;Skočková et al, 2015;Sudarwanto et al, 2015;Odenthal et al, 2016). However, relatively few studies have been conducted in Colombia on antibiotic resistance in foodproducing animals and their products (Vanegas López et al, 2012;Jiménez Velásquez et al, 2013;DonadoGodoy et al, 2015) compared to other countries and to our knowledge, this is the first study conducted to determine the occurrence of ESBL-producing Enterobacteriaceae in bulk-tank milk in Colombia.…”

“…La producción de BLEE por bacterias reduce la eficacia de un amplio rango de antibióticos betalactámicos como cafalosporinas de tercera generación y monobactámicos (38), y se ha documentado que los animales productores de alimentos son importantes reservorios de Enterobacteriaceae productora de BLEE (39). E. coli multiresistente ha sido aislada de leche bovina en varios estudios previos (40)(41)(42)(43)(44)(45)(46), lo que demanda muchos más estudios para establecer la importancia de este fenómeno en el ámbito nacional.…”

Tasa de incidencia de mastitis clínica y susceptibilidad antibiótica de patógenos productores de mastitis en ganado lechero del norte de Antioquia, Colombia

2017

View full text Add to dashboard Cite

ResumenIntroducción: la mastitis se define como la inflamación de la glándula mamaria causante de grandes pérdidas económicas en hatos lecheros, lo que amerita su investigación. Objetivo: determinar la tasa de incidencia de mastitis clínica TIMC, la etiología asociada y la sensibilidad antibiótica de patógenos aislados de casos de mastitis en ganado lechero. Materiales y métodos: se siguieron 37 hatos por 12 meses para el diagnóstico de mastitis cílínica (MC). A las muestras de leche de los casos de MC se les realizó cultivo bacteriológico y a estas, así como a los aislamientos de casos de mastitis subclínica de un estudio previo, se les efectuó prueba de susceptibilidad antibiótica. Para el análisis de la información se utilizó estadística descriptiva estándar. Resultados: TIMC fue de 13,8 casos por 100 vacas-año a riesgo. Se aislaron 188 patógenos totales de casos de MC, entre los cuales el Streptococcus agalactiae, el Streptococcus pyogenes y el Corynebacterium spp. fueron los más frecuentes, con 29,8; 11,7 y 5,9 %, respectivamente. Se halló una alta sensibilidad de las bacterias contagiosas para los antibióticos cloxacilina y cefoperazone. Conclusiones: en el presente estudio se encontró una TIMC de 13,8 casos por 100 vacasaño a riesgo. Los patógenos más prevalentes identificados en casos de MC fueron contagiosos. Se encontró una alta sensibilidad de las bacterias contagiosas para la mayoría de los antibióticos β-lactámicos.Palabras clave: bovinos, leche, mastitis, prueba de sensibilidad antibiótica, resistencia antimicrobiana, tasa de incidencia de mastitis clínica.Incidence rate of clinical mastitis and antibiotic susceptibility of mastitis-producing pathogens in dairy cattle from Northern Antioquia, Colombia

Antimicrobial resistance profiles of Escherichia coli and prevalence of extended‐spectrum beta‐lactamase‐producing Enterobacteriaceae in calves from organic and conventional dairy farms in Switzerland

This study compared the antimicrobial resistance (AMR) among commensal Escherichia coli in the fecal microbiota of young calves raised on organic and on conventional dairy farms in Switzerland. Further, fecal carriage of extended‐spectrum beta‐lactamase (ESBL) producing Enterobacteriaceae was assessed for calves from both farming systems. Where possible, data on antimicrobial usage (AMU) were obtained. Antimicrobial susceptibility testing was performed on a total of 71 isolates using the disk diffusion method. ESBL producers were characterized by polymerase chain reaction‐based multilocus sequence typing and sequencing of the bla ESBL genes. Organically raised calves were significantly more likely to harbor E. coli that showed AMR to ampicillin (odds ratio [OR]: 2.78, 95% confidence interval [CI]: 1.02–7.61, p = 0.046), streptomycin (OR: 3.22, 95% CI: 1.17–8.92, p = 0.046), kanamycin (OR: 11.3, 95% CI: 2.94–43.50, p < 0.001), and tetracycline (OR: 3.25, 95% CI: 1.13–9.31, p = 0.028). Calves with reported AMU were significantly more likely to harbor E. coli with resistance to ampicillin (OR: 3.91, 95% CI: 1.03–14.85, p = 0.045), streptomycin (OR: 4.35, 95% CI: 1.13–16.7, p = 0.045), and kanamycin (OR: 8.69, 95% CI: 2.01–37.7, p = 0.004). ESBL‐producing Enterobacteriaceae (18 E. coli and 3 Citrobacter braakii) were detected exclusively among samples from conventionally farmed calves (OR: infinity [∞], 95% CI: 2.3–∞, p < 0.0013). The observations from this study suggest that AMR is highly prevalent among commensal E. coli in young dairy calves, irrespective of the farm management system, with proportions of certain resistance phenotypes higher among organic calves. By contrast, the occurrence of ESBL producers among young dairy calves may be linked to factors associated with conventional farming.
