PEDV was not infectious on cell culture within 7 days when stored at room temperature and within 21 days when stored at refrigerated temperature.

This study demonstrates the successful transfer of meloxicam from sows to piglets through milk and corresponding analgesia.

Under the conditions of this study, fecal shedding of TTSuV is independent of PoRVA infection in diarrheic piglets aged 1 to 3 weeks.

Even in the absence of clinical signs, growth rate and feed intake are likely to be reduced by L. intracellularis infections. There is a trend that also PCV2 infections can exert a similar negative influence.

A survey of national animal influenza surveillance programmes was conducted to assess the current capacity to detect influenza viruses with zoonotic potential in animals.

Comparing different vaccination strategies against M. hyopneumoniae indicates varying levels of protection. M. hyopneumoniae is still a major problem despite the widely applied vaccination.

Serological data that were obtained by testing meat juice samples from various pig herds were analyzed as proof of the "meat juice multi-serology" concept.

Farms that use living animals for the exposure to gilts during the acclimatization and farms that had increased number of weaned piglets per sow and year were less likely to test positive for M. hyopneumoniae and less likely to develop clinical symptoms of EP in fattening pigs.

From 2011 to 2013, the French network for the surveillance of influenza viruses in pigs (Résavip) has made it possible to conduct 629 visits in 476 farms.

Altogether, these results indicate that modifying feeding practices could help to prepare animals to overcome an influenza infection.

A total of 152 pork samples were collected in markets and supermarkets in Ho Chi Minh City. Antimicrobial susceptibility of the isolates to antimicrobial agents was determined.

This work represents the first report of Corynebacterium pseudotuberculosis from caseous lymphadenitis lesions in Black Alentejano pig and alerts for the importance of the establishment of suitable control and sanitary management practices

Respiratory and diarrhoeal conditions were mentioned most frequently (>60 per cent) for antibiotic prescribing in pigs.

Co-infection with PRRSV enforces clinical signs of PMWS, the influence of other viral co-infections is not clear.

Possible modifications to farm type and pig flow should be considered when constructing IAV control and prevention strategies.

A single descendant of a PVL-positive methicillin-sensitive ancestor circulating in sub-Saharan Africa rose to become the dominant CA-MRSA clone in Europe, the Middle East, and North Africa.

An Italian study investigated the intestinal bacterial diversity of healthy pigs with different susceptibility to ETEC and fed different Trp levels.

Results suggest that clinical outbreaks of A. pleuropneumoniae are unlikely to be caused only by spread of the pathogen by clinically diseased pigs.

The results indicates no evidence of infectivity of the PEDV RNA in the SDPP lot utilized.

Taken together, swab samples could be recommended as a pragmatic approach to sample fallen wild boar.

Pigs can readily induce adaptive mutational changes to a precursor pandemic-like virus to transform it into a highly virulent and infectious form akin to that of the pandemic H1N1/2009 virus.

Data on this article provide proof of concept that contaminated feed pellets (complete feed) can serve as a vehicle for PEDV infection of naïve pigs using natural feeding behavior.

The authors have demonstrated that PEDV can become airborne, remain infectious while suspended in the air, and that PEDV genetic material can be transported long distances following natural infections.

This benefit for the offspring highlights the potential of oral immunisation of sows against C. suis as a possible passive vaccination strategy for new born piglets against this important pathogen.
