Porcine pleuropneumonia (PPP) caused by Actinobacillus pleuropneumoniae (App)
Publish Date: September 1, 2021
Porcine pleuropneumonia (PPP) is an infectious respiratory disease of swine caused by the bacteria Actinobacillus pleuropneumoniae (APP). The disease occurs throughout the world and results in significant economic losses due to mortality, growth retardation, veterinary costs and slaughter condemnations. It is rather well controlled in North America, but PPP remains a major concern in Latin-American, Australasian and most European countries.

Streptococcus Suis Disease in Pigs
Publish Date: December 6, 2021
The bacteria, Streptococcus suis (S. suis) causes significant disease in swine operations worldwide. In fact, it is now the most common cause of systemic disease in nursery piglets. Furthermore, there has been a marked increase in S. suis cases recently, mainly in herds who have reduced and/or eliminated the use of preventive medications (Poeta Silva, 2021). S. suis colonizes the tonsils of most pigs and is capable of causing disease in the brain via meningitis (brain barrier inflammation) and through septicemia (bloodstream infection), thus reaching other organs. While S. suis is most often associated with meningitis, other manifestations include arthritis, polyserositis (widespread membrane inflammation), endocarditis (heart valve inflammation) and, as a secondary cause, pneumonia (lung inflammation). S. suis is also a zoonotic agent able to cause serious disease (mostly meningitis) in people working with pigs or pork-derived products.

The first description of gastric ulcers was written in 1897, but the condition remained as a rare or undiagnosed problem until the 1950’s and 60’s. Outbreaks of gastric ulcers coincided with the introduction of modern feeding and husbandry practices such as the use of grain-based processed feeds and confinement rearing. Today, gastric ulceration is a common problem almost everywhere in the world, and a major cause of mortality and economic loss, as well as a welfare concern.
