PATHOGENS 08/03/21 Staphylococcus aureus in Intensive Pig Production in South Africa: Antibiotic Resistance, Virulence Determinants and Clonality. Although Staphylococcus aureus is a major threat to the veterinary, agricultural, and public health sectors because of its zoonotic potential, studies on its molecular characterisation in intensive animal production are rare.
We phenotypically and genotypically characterised antibiotic-resistant S. aureus in intensive pig production in South Africa, using the farm-to-fork approach. Samples (n = 461) were collected from the farm, transport vehicles, and the abattoir using the World Health Organisation on Integrated Surveillance of Antimicrobial Resistance (WHO-AGISAR) sampling protocol. Bacteria were isolated using selective media and identified using biochemical tests and polymerase chain reaction (PCR). Phenotypic resistance was determined using the disk diffusion method. Selected resistance and virulence genes were investigated using PCR.

Pisanic, C. Ordak, D.C. BMC VETERINARY RESEARCH 18/01/21 The presence of antibiotic-resistant Staphylococcus spp. and Escherichia coli in smallholder pig farms in Uganda. Study design The study was conducted in the four sub-counties closest to Lira town, Lira district, in the northern region of Uganda.
A list of 250 pig farmers were obtained from the District Veterinary Office. From this list, 20 herds, meeting the inclusion criteria of having at least one sow and keeping the pigs confined or tethered, were selected by simple randomization. One farmer had sold his pigs prior to the visit, and thus, 19 herds remained in the study.
As categorized by Ouma et al. , herds with less or equal to three sows/year were termed small, while those with more than three sows/year were termed large. Collection of data on the antibiotic usage Information on the antibiotic usage during September 2018–September 2019 was gathered by several methods applied in all herds.

Veterinarians are more likely to acquire zoonotic infections compared to the general population (Baker & Gray, 2009; Taylor, Latham, & Woolhouse, 2001).
The swine population represents an important potential reservoir for zoonotic viral, bacterial pathogens and helminths (e.g., hepatitis E virus [HEV], methicillin‐resistant Staphylococcus aureus [MRSA], Leptospira and Ascaris suum [A. suum ]). The HEV is classified into four human pathogenic genotypes (gt1–4), with gt1 and gt2 exclusively infecting humans (Mushahwar, 2008). Acute HEV infection is usually self‐limiting and probably less than 5% infected, develop symptoms of acute hepatitis. Domestic swine and wild boars are the main animal reservoir for HEV gt3 and gt4 (Lewis, Wichmann, & Duizer, 2010).
Berto et al. (2012) found in commercial swine farms in six European countries, other than Austria, a faecal HEV prevalence in growers of 20%–44% and in fatteners of 8%–73%. Ann. Occup.

It is important to keep the number of MRSA infections at a low level.
In a PhD project at the National Food Institute, Technical University of Denmark, the latest technologies within whole genome sequencing were exploited to develop new methods to identify genes which are important for the survival of MRSA in pigs. Traditionally, MRSA has been associated with severe infections which occur in hospitals and result in prolonged diseases and increased mortality.
However, in recent years, MRSA has spread to the rest of the community, e.g. MRSA CC398 is found in pig production. MRSA is resistant to the antibiotics we normally use for treatment of Staphylococcus infections. In her PhD project at the National Food Institute, PhD student Mette Theilgaard exploited the latest technologies within whole genome sequencing and studied the entire DNA of MRSA CC398.

PLOS 25/02/10 Prevalence of Livestock-Associated MRSA in Communities with High Pig-Densities in The Netherlands. Abstract Background Recently, livestock-associated methicillin-resistant Staphylococcus aureus CC398 has been discovered in animals, livestock farmers and retail meat.
Recently, an outbreak of skin lesions due to MRSA occurred in workers at a pig farm in regional Australia and both the humans and pigs were shown to have a high prevalence of carriage of either the human-strain ST93 or porcine strain ST398. This study closely scrutinises this outbreak to determine factors associated with MRSA carriage amongst the workers. Methods Information on potential risk factors was collected from employees by means of a questionnaire. Results.

The isolates belong to a livestock-associated lineage previously reported in North America and Europe, CC398, and a highly virulent USA300-like ST8-IV variant, which is the predominant community-associated lineage in Latin America.

Background Recent research has demonstrated that many swine and swine farmers in the Netherlands and Canada are colonized with MRSA.
However, no studies to date have investigated carriage of MRSA among swine and swine farmers in the United States (U.S.). Methods We sampled the nares of 299 swine and 20 workers from two different production systems in Iowa and Illinois, comprising approximately 87,000 live animals.

SANTE BELGIQUE 12/09/07 Souche MRSA dans les porcheries belges - 12.09.2007 - Une étude réalisée à la demande du précédent minis. L’EFSA publie les résultats de la première enquête sur le SARM chez les porcs dans l’Union Européenne. Communiqué de presse 24 novembre 2009 L’Autorité européenne de sécurité des aliments (EFSA) a publié les résultats de la première enquête réalisée à l’échelle de l’UE sur le SARM (Staphylococcus aureus résistant à la méthicilline) chez les porcs de reproduction.
Les résultats indiquent que le SARM, une bactérie résistante à de nombreux antibiotiques, est communément détecté dans les exploitations où sont élevés des porcs reproducteurs dans certains États Membres de l’UE. L’enquête fournit des estimations sur sa présence et formule des recommandations relatives à l’intensification de la surveillance et des recherches sur les causes et les implications de la découverte du SARM dans les exploitations porcines au sein de l’UE. L’enquête s’est déroulée au sein de 24 États membres . Parmi ceux-ci, 17 ont détecté un certain type de SARM dans les exploitations de porcs reproducteurs et 7 n’en ont détecté aucun.
