How is it possible that a virus that causes an acute infection in an animal can remain on a farm throughout time?
Influenza researchers are trying to stimulate antibody responses towards parts of the HA that are the least variable from strain to strain. One approach that seems promising is choosing two antigenically very different strains within the H1 or H3 subtype for the primary and subsequent booster vaccinations.
Could the vaccination against Salmonella in pigs be as crucial as it has been in poultry?
Main elements that can be found in the digestive environment and how they are involved in gut health.
What is the "gut health" concept that everyone talks about? Why is it important?
Enzyme-linked immunosorbent assay, serum virus neutralization test, haemoagglutination test, and immunoperoxidase monolayer assay are explained.
Feeding, biosecurity and concomitant diseases as factors involved in the perpetuation of Salmonella in the farm.
Nowadays several laboratory techniques allow to evaluate the cellular immune response.
This article discuss about the protection of the placenta, the colostrum, the immunity conferred by milk and the congenital acquired immunity of the piglet.
Montse Torremorell speaks about different alternatives that are being explored to obtain live animal samples at a reasonable cost.
The immune, endocrine and central nervous systems communicate through anatomical and hormonal-neuropeptides pathways.
Most infections with occupational diseases occur at slaughter, when humans handle potentially infected meat or body fluids. We’ll introduce two major ones here: erysipelas and S. suis infection.
The skin is the first defensive line, as is the largest organ of the body.
After reviewing some of the main hazards for pork producers in previous articles, this article is devoted to practical measures describing how to reduce risks of illnesses and injuries from those hazards.
Mucosal surfaces, constantly exposed to foreign antigens, have developed the ability to protect the host from potentially harmful organisms by means of innate and acquired immune responses.
Illness and injuries can cost serious economic, physical, and emotional health issues that can deter from an efficient and enjoyable production system and home life. In this article, I will list several categories of health and safety issues for workers.
After over 20 years of research effort, the question of how to balance efforts in Salmonella control among the preharvest, harvest, and post-harvest sectors remains alive, but ‘silver bullets’ for on-farm control of Salmonella in pigs have proven elusive.
In the primary humoral immune response, a single class IgM in monomeric form is initially secreted. The secondary response induced by a subsequent exposure to the same antigen will be mainly characterized by the production of IgG isotype but at higher titre and affinity.
By far, the most common and most obvious health hazard to producers and workers is accidental needle sticks. This article will focus on accidental needle sticks, what risks they present, and how to prevent them.
