Outbreak of multiply resistant enterobacteriaceae in an intensive care unit: Antimicrobial drug resistance in strains of Escherichia coli isolated from food sources.

The excessive or inappropriate use of antibiotics in farm animals can generate adaptation of bacteria to antimicrobials FAO, ; thus, it has become a matter of great importance for health authorities WHO, ; EFSA, Anyway, the discovery of these bacteria Enterobacter sp.

Journal of Infection, v. Presence of extended-spectrum beta-lactamase ESBL -producing Enterobacteriaceae in bulk-tank milk of bovine dairy farms in Antioquia, Colombia. A case series and review of eshendido literature.


Ministerio de Agricultura y Desarrollo Rural de Colombia. Feeding waste milk to calves and antibiotic resistance.

Concurrent outbre- aks of extended-spectrum beta-lactamase-producing organisms of the family Enterobacteriaceae in a Warsaw hospital. Int J Antimicrob Agents. Clin Microbiol Rev ; The fact that most of the farms had reported performing milking routine following technical recommendations favors the sanitary situation in the municipality because if there is no monitoring of good milking practices, there would be more cases of mastitis and therefore a greater usage of antibiotics with the possibility of developing or acquiring resistance Oliver and Murinda, The use of bulk-tank milk samples could serve to monitor trends in resistance to antibiotics in dairy farms Berge et al.

The only isolate that displayed sensitivity to SAM was E.

Conflicts of interest The authors declare they have no conflicts estendivo interest with regard to the work presented in this report. International Journal of Food Microbiology, v.


Raw milk, for example, can be contaminated intramammary with Enterobacteriaceae during mastitis processes, directly through animal feces or indirectly during milking through milkers or milking equipment Dahmen et al. Occurrence of integron-associated resistance gene cassettes located on antibiotic resistance plasmids isolated from a wastewater treatment plant. Rev Colomb Cienc Pecu ; For the exploration of risk factors, information on dairy farm management practices was recorded using a questionnaire and the associations of predictors and results were tested with a logistic regression analysis.

The isolates were subjected estendixo confirmatory phenotype tests for the presence of ESBL.

Information on variables related to general conditions of the farm, production, sanitation, and hygiene, and the use of antibiotics was collected Tables 1 and 2. The susceptibility patterns shown by both tests were similar.

Outbreak of ceftazidime resistance caused by extended-spectrum beta-lactamases at a Massachusetts chronic-care faci- lity. A total of 14 antibiotics were evaluated and interpreted according to CLSI standards: Only farms having their own bulk-tank were selected. That is, farms that store milk in collective or community tanks were not considered.

Transferable resistan- ce to cefotaxime, cefoxitin, cefamandole and cefuroxime in clinical isolates of Klebsiella pneumoniae and Serratia marcescens.

Resistance to β-lactams among Acinetobacter spp isolated from hospital sewage in southern Brazil

re Interpretative reading of the non-fermenting gram-negative bacilli antibiogram. In the same way, situations in which the choice and provision of antibiotics is in the hands of a person other than the veterinarian may cause variations in bacterial sensitivity along with recurrence of the presentation of microorganisms associated with different pathologies as a consequence of not normally performing isolation or evaluation by antibiogram of the causal agent of infection Betancourt et al.


Notably, the range of antibiotics for which resistance was acquired is large and sufficiently worrisome because it shows the severity of the emergence of antibiotic resistance in different pathogens.

In this study, feeding calves with waste milk milk of cows with antibiotic treatment -although not found as a risk factor- continues to be a frequent activity in dairy farms of the municipality, despite current knowledge of the association between this practice and increased resistance to antimicrobials in calves Langford et al.

Enferm Infecc Microbiol Clin ; 31 5: Sup Pharmacotherapy ; 24 Information about CFU values was obtained from the purchase invoice generated by the milk processor. In this study, dairy farms with equal number of milk cooling tanks located in Northern Antioquia Colombia were sampled to determine the presence of ESBL-producing Enterobacteriaceae in bulk-tank milk and to explore the risk factors associated to its presence.

The authors declare they have no conflicts of interest with regard to the work presented in this eepectro. Antimicrobial resistance in animals and in human being.

However, sincethe enzyme cefotaxime-munich CTX-M became one of the most frequent and ESBL-producing Eschericha coli emerged as an important pathogen in the community Blanco et al.
