“…Interestingly, the resistance of isolates was remarkably higher for older compounds, with the exception of gentamicin, which is a relatively old compound that has had little use in animals. In agreement with the findings reported in other countries (Bywater et al, 2004;Knezevic & Petrovic, 2008;Miranda et al, 2008a), resistance to this antimicrobial of animal-origin strains is rare. …”

“…Ampicillin ( On the other hand, the resistance levels found for some antimicrobials in isolates obtained from the chicken meat tend to be higher than the levels reported in other countries (Bywater et al, 2004;Kijima-Tanaka et al, 2003;Miranda et al, 2008a;Sa´enz et al, 2001;Van den Bogaard et al, 2001). It is remarkable that the high level of resistance observed in poultry-origin isolates for both antimicrobials are commonly used in poultry medicine, such as ampicillin (76.5%), doxycycline (56.3%), sulfisoxazole (77.3%), or ciprofloxacin (77.3%) (Miranda et al, 2008b;Van den Boogard et al, 2001) and also for antimicrobials that are rarely used in poultry medicine, such as chloramphenicol (58%).…”

The presence of Escherichia coli in foods taken from the grocery stores and the supermarkets in Hidalgo State (Mexico) was determined for 73 samples of poultry meat, 60 samples of pork, 86 samples of beef, and 66 samples of vegetables. A total of 352 E. coli strains were isolated, identified, and analyzed by an agar disk diffusion assay for their resistance to 10 antimicrobials. Poultry meat and vegetables taken from groceries showed significantly higher counts (P ¼ 0.0002 and P ¼ 0.0461, respectively) when compared with the samples taken from supermarkets. Compared with the isolates recovered from other foods, E. coli isolated from chicken meat had higher levels of antimicrobial resistance against all antimicrobials tested, with the exceptions of nitrofurantoin resistance of isolates from pork and streptomycin resistance in isolates from pork and beef. In addition, the E. coli isolates from samples taken from the groceries showed higher resistance rates than the isolates from samples taken from the supermarkets for the cases of pork isolates resistance to ampicillin (P ¼ 0.0497), chloramphenicol (P ¼ 0.0075), doxycycline (P ¼ 0.002), and streptomycin (P ¼ 0.0094) and beef isolates resistance against ampicillin (P ¼ 0.0048), streptomycin (P ¼ 0.002), and sulfisoxazole (P ¼ 0.003). The present study revealed that the observed resistance rates correlated well with those reported in the national surveillance programmes of developed countries, with the exception of isolates from chicken meat, which have higher resistance rates. Also, from a microbiological safety point of view, samples taken from supermarkets were in a much better conditions than those obtained from the groceries.Keywords: E. coli; antimicrobial; food-borne; resistance; Me´xico La presencia de Escherichia coli fue investigada en 73 muestras de carne de pollo, 60 muestras de carne de cerdo, 86 muestras de carne de vacuno y 66 muestras de alimentos vegetales muestreados en pequen˜os ultramarinos y supermercados en el estado de Hidalgo (Me´xico).

“…in pigs. In fact, Salmonella infection persists in pig herds in the subclinical stage and pigs are often clinically asymptomatic carriers of Salmonella [15], which might be attributable to the isolation of Salmonella from apparently healthy pigs. The prevalence of Salmonella on pig carcasses (19%) was higher than in faeces (8.6%).…”

Background: Salmonellosis is considered one of the most widespread food-borne zoonoses in industrialized as well as developing countries. The presence of Salmonella in food animals at slaughter and the consequent cross-contamination of edible carcass tissues present a significant food safety hazard. Methodology: Samples were collected from randomly selected pigs at the Ndumbuini abattoir in Nairobi. Isolates were confirmed to be Salmonella by biochemical tests and characterised by serotyping, phage typing and plasmid analysis. Minimum inhibitory concentrations (MICs) of eight antimicrobials were determined and the resistant isolates were screened for resistance genes by PCR. Results: Sixteen (13.8%) of 116 samples were positive for Salmonella. Three Salmonella enterica subsp. enterica serovars, namely Saintpaul, Braenderup, and Heidelberg were identified, S. Saintpaul being predominant. Antimicrobial resistance was found in 35.7% of the isolates. The S. Heidelberg isolates were susceptible to all the antimicrobials tested. Multidrug resistance was found in 7.1% of the Salmonella isolates. Plasmids were only detected in S. Heidelberg. Ampicillin resistance was based on expression of a bla TEM gene, while chloramphenicol, streptomycin, and tetracycline resistances were encoded by the genes catA1, strA, and tet(A), respectively. Conclusions: Pigs may serve as reservoirs of antimicrobial resistant Salmonella and slaughterhouse cross-contamination of pork may be a food safety risk.

“…The actual increase of resistance to erythromycin (drug of the therapeutic choice) in thermophilic Campylobacter spp. isolated from humans has become allarming (Bywater et al, 2004;Cardinale et al, 2002). Emergence of the resistant strains coincided with the beginning of macrolides use, for the most part thylosine, in veterinary medicine, mainly in swine farming ( Aarestrup and Engberg, 2001;Luber et al, 2003).…”

The sensititivity of thermophilic Campylobacter strains isolated from caecum of broiler chickens as well as caecum and colon of pigs and human stools, were tested against erythromycin. In 16 strains isolated in broiler chickens, resistance rate was found to be 12.50%. Three of 10 strains of Campylobacter jejuni and one of 6 strains of Campylobacter coli isolated from broiler chickens were resistant to erythromycin. In 15 strains of thermophilic Campylobacters isolated from pigs, resistance rate to erythromycin was 40.00%. Resistance was exhibited more often in C. coli (50.00%) as compared to C. jejuni (20.00%). In 24 strains isolated from humans, resistance was demonstrated at the rate of 12.50%. Out of 17 strains of C. jejuni isolated from humans, resistance was exhibited in 17.65% strains. None of 7 strains of C. coli isolated from humans exhibited resistance to erythromycin. Thermophilic campylobacters, especially C. coli isolated from pigs were more resistant to erythromycin than strains isolated from humans and broiler chickens. Therefore, a great attention should be directed to the macrolides monitoring in swine farming in order to prevent resistance in animals and its subsequent spread to human.

A European survey of antimicrobial susceptibility among zoonotic and commensal bacteria isolated from food-producing animals

Abstract: Antimicrobial resistance among enteric organisms in food animals varied among countries, particularly for older antimicrobials, but resistance to newer compounds used to treat disease in humans was generally low.
