Genomic changes can be associated with increased virulence or decreased immunogenicity.

The litter size of the recent and the last farrowing batches was significantly reduced, and the suckling pigs showed an obvious varying weight, condition and viability.

Novelties about the excretion routes, the transmission routes, the risk factors, etc., and explanation about how the PCV2 becomes a pathogenic virus.

The nervous system symptomatology is characterized by some cases of meningitis and opistothonus, dizziness and serious deep depression in a great number of animals. The necropsy shows, in all the cases, a serious lung congestion and an enteritis with a variable seriousness with a more or less important involvement of the mesenteric lymph nodes.

The most effective way of avoiding the production losses associated with the PCV2 consists in avoiding the appearance of the viraemia by inducing a passive or an active immunity that minimizes the circulation of the virus in the farm.

There are 3 potential options to stabilize BTW herds following an outbreak that have all proven successful over time. They have very different cost and risk profiles and a through economic assessment is needed to determine what the best course of action is for each new outbreak.

This case describes an acute outbreak of gastric ulcers in pigs of 30-40 kg live weight that affected 38 farms throughout a year and that presented mortalities from a 5% up to a 40% depending on the severity of the cases.

This study, based on some 120,000 sows, quantifies the reduction of the risk of introducing PRRS viruses when using air filtering.

After the banning of antibiotics as growth promoters, there was an increase in their total consumption due to the therapeutics treatments...

Over the last several years, new sampling, monitoring and diagnostic tools for the swine industry that are faster, simpler and more cost effective have been developed and validated. One of these techniques is the sampling and use of oral fluids (saliva) as specimens for diagnostics in swine.

Here we present a table of differential diagnosis of the most common diarrheas during lactation.

In 1996, the NFMDTF drafted a national plan to address the 1995 FMD epidemic wherein 98,000 animals were reported to have been affected.

Rotaviruses are important enteric pathogens that affect newborns of several animal species. In swine, they can cause gastroenteritis in piglets.

Escherichia coli is an enterobacteria that forms part of the normal intestinal microbiota of healthy animals. Usually, E. coli present in animals are communal antipathogenic strains and they even play a beneficial role, since they compete in several ways with the pathogenic strains in the ecological niche of the lumen.

Currently, the human risk factors associated with S. suis infection are: 1) Eating raw/undercooked pork meat, 2) Being a farm worker with hog contact or 3) Butchers. To date, there is no evidence of human-to-human transmission of S. suis.
