Escherichia Coli Resistance And Gut Microbiota Profile In Pigs Raised With Different Antimicrobial Administration In Feed, Caroline Pissetti, Jalusa Deon Kich, Heather K. Allen, Claudia Navarrete, Débora Da Cruz Payão Pellegrini, Nelson Morés, Marisa Cardoso

International Conference on the Epidemiology and Control of Biological, Chemical and Physical Hazards in Pigs and Pork

Antimicrobials have been widely used in veterinary medicine for disease treatment, disease prevention, and growth promotion. Although, the mechanisms about in-feed additives use are still not completely understood, it is accepted that its use improves feed efficiency by reducing the microbial load in the intestinal tract, thereby reducing the pressure on the immune system and increasing energy availability for the animal. However, disruption to commensal bacterial communities by antibiotics in some cases can increase the gut colonization by pathogenic bacteria. In this sense, the aim of this study was to evaluate the Escherichia coli antibiotic resistance and the gut microbiota ...

International Conference on the Epidemiology and Control of Biological, Chemical and Physical Hazards in Pigs and Pork

The wild boar (Sus scrofa), exotic invasive specie, is currently distributed in many Brazilian states, including Santa Catarina (SC) and Rio Grande do Sul (RS). Since the wild pigs are susceptible to zoonotic pathogens as Leptospira spp, Toxoplasma gondii and Brucella spp, their large populations, movements and dispersion can spread diseases, being a potential transmission source to humans, livestock and other sylvatic sympatric species. Despite its importance are there few information about sanitary status of this wild populations and their impact for human and livestock health in Brazil. Objective this work was to investigate the presence of antibodies to Brucella ...

Streptococcus suis is a major pathogen in the pig industry, associated with a wide variety of pigs diseases, such as meningitis, arthritis, bronchopneumonia, endocarditis, polyserositis and septicaemia. In addition, it is a zoonotic agent causing severe infections in people related with infected pigs or pork-derived products. The control of the disease is based on the antimicrobial therapy and sanitary measures, since there are not available commercial vaccines yet.

International Conference on the Epidemiology and Control of Biological, Chemical and Physical Hazards in Pigs and Pork

Salmonella enterica subspecies enterica is recognized as the etiological agent of Salmonellosis, a zoonotic disease transmitted in humans through contaminated food. In 2015, Salmonella s. p. was reported as the second bacterial agent responsible of gastro-enteritis in the European Union (EFSA, 2016). Pig consumption is considered as a major source of human Salmonella infections (Bonardi, 2017). Salmonella subspecies can be divided in 1530 serovars based on different epitopes and surfaces antigens. Associations exist between serovars and livestopchk species. In Pigs, in France, Salmonella Typhimurium, Derby and recently the monophasic variant of S. Typhimu-rium (vmST) are the most frequently isolated serovars ...

International Conference on the Epidemiology and Control of Biological, Chemical and Physical Hazards in Pigs and Pork

Yersiniosis is a human disease mainly due to the ingestion of raw or undercooked pork meat contaminated mostly with Yersinia enterocolitica (Ye). In France, 74.3% of pig batches at slaughterhouses carried pathogenic Ye. Among them, biotype 4 (BT4) and biotype 3 (BT3) were often recovered. PFGE is one of the most used methods to type Ye, with the restriction enzymes, XbaI and NotI. Nevertheless, MLVA method based on the diversity of six loci tends to replace PFGE; this method showed a higher discriminatory power in others studies. We investigated the genetic diversity of Ye strains isolated in 2009 and ...

The energy demand increase and recent new regulation for biomethane in Brazil have aroused new interests and perspectives for biogas from livestock wastes, especially swine manure. Brazil is the largest producer of animal protein and has perspective to keep growing in the next years, but to achieve this goal good practices of livestock waste management are required. The anaerobic digestion has become a common practice to treat the manure and also reduce production costs through energy recovery (Cherubini et al. 2015).

Alternatives To Antimicrobial Treatment In Weaners—The Veterinary Practitioner's Solution, Frede Keller

International Conference on the Epidemiology and Control of Biological, Chemical and Physical Hazards in Pigs and Pork

One way of lowering the need for antimicrobial treatment is to ensure that piglets are healthy and strong at weaning. This implies that the weaning weight should be 6-7 kg. Unfortunately, many piglets only weigh 3-5 kg at weaning, which predisposes them to disease including diarrhea, because they are not necessarily ready for a soy-based diet at weaning.

A Sudden Increase In Salmonella—How The Surveillance System Reacted: A Danish Experience, Vibeke Møgelmose, Lene Lund Lindegaard, Jan Dahl

International Conference on the Epidemiology and Control of Biological, Chemical and Physical Hazards in Pigs and Pork

Denmark has had a serological surveillance of finisher herds since January 1995, and the current surveillance of Salmonella on carcasses has been in place since 2001. Both surveillances are parts of the Danish Action Plan for Salmonella in pigs and pork. Variations in the Salmonella prevalence are evaluated, and if a variation is exceptional, much effort is done to try to find the reason for the variation, to correct it and to learn from it.

International Conference on the Epidemiology and Control of Biological, Chemical and Physical Hazards in Pigs and Pork

In recent years Salmonella enterica serovar Typhimurium 1,4[5],12:i:- (mono-phasic variant of S. Typhimurium or vmST) was focused as a major zoonotic problem because produce human gastroenteritis outbreaks in many countries. Human disease caused by this serovar is considered as emergent in European Union countries and actually is ranked as the third most reported serotype after S. Enteritidis and S. Typhimurium (EFSA, 2016; Fernandes et al., 2016).

Hepatitis E is a zoonotic emerging disease distributed worldwide. The domestic swine and wild boars (Sus scrofa) are known as important reservoirs of HEV although HEV infections have been detected in other animal species. The southern region of Brazil has the largest swine productions in the country, ranging from highly-specialized commercial swine productions to small-scale non-commercial pig farms. The small-scale farms allow interactions between wild boars and domestic pigs, when occasionally pathogens transmission can occur between these populations. The aim of this study was to determine HEV seroprevalence in non-commercial domestic pigs and wild boars from two southern Brazilian states ...

A Study Of The Effect Of Movement Of Outdoor Pigs To A New Site On Salmonella Prevalence, Richard Piers Smith, Becky Gosling, Rob Davies

International Conference on the Epidemiology and Control of Biological, Chemical and Physical Hazards in Pigs and Pork

Outdoor breeding of pigs in Great Britain constitutes a substantial proportion of the British pig industry, with at least 40% of the breeding herd kept outdoors. Outdoor production is viewed as more welfare friendly and forms a break between cereal crops. Outdoor pig production has a tendency for high Salmonella seroprevalence at slaughter, with evidence for a wide diversity of resident and transient infections on farm, often showing some overlap with local environmental and wildlife isolates. Outdoor pigs may be at increased risk of infection due to: the lack of a controlled environment that can be cleaned and disinfected between ...

Meat consumption is frequently associated with foodborne diseases. The onset of such occurrences may be due to failures on animal health surveillance or during meat processing. Many efforts are made in the industry to minimize any kind of meat contamination which can affect human health. Salmonella has an important role in the public health and economy, once it is recognized as one of the most important zoonosis (Valero et al., 2014). In Brazil, 90% of reported cases involving foodborne pathogens, in which the pathogens were identified, from 2007 to 2016, were caused by Salmonella spp. (Brazil, 2016).

In this study, we assess whether on-farm serology may be useful for predicting Salmonella shedding at slaughter. Serology on serum samples collected 60 and 90 on fattening and three days before slaughter predicted somewhat shedding at slaughter with no significant differences among them. Pigs with higher OD% values at these point times would have higher risk of shedding when arriving to slaughter. On-farm serology may help to predict to some extent the risk of Salmonella shedding at slaughter in seropositive fattening units, which may allow for prompt on-farm and slaughter interventions to mitigate the risk of shedding when pigs arrive ...

The use of antibiotics in livestock production is very common and widespread. The reason for their use can be very diverse. Examples are the treatment of clinically sick animals, the improvement of growth performance, as well as the prevention of common bacterial infections. However, the extensive use of such antimicrobials raised concerns of increasing the incidence of resistant pathogenic bacteria, which has a negative impact not only on livestock production, but also on human health. In the last years, many different substances have been investigated as suitable alternatives to the use of antibiotics as growth promoting agents and as prophylactic ...

International Conference on the Epidemiology and Control of Biological, Chemical and Physical Hazards in Pigs and Pork

Salmonella is the second most commonly reported zoonotic gastrointestinal pathogen in the European Union. Although the majority of foodborne outbreaks have been linked to the consumption of eggs and egg products (44.0%), a substantial proportion originate from pork and pork products (9.3%). Biosecurity measures correctly implemented on farm are important to reducing Salmonella carriage in live pigs and consequently the number of Salmonella contaminated carcasses entering the food chain.
