The use of preweaning units or pens for piglets with low weight allows: 1. To wean them applying an appropriate management for it. 2. More weight homogeneity in the nurseries. 3. Keep an appropriate all-in/all-out management system in the farrowing rooms.

Are the nurseries becoming more complicated? (3/3) Streptococcus suis

In this third article, we want to to talk about a common guest in the nurseries: Streptococcus suis, the causative agent of clinical pictures that can include meningitis, arthritis and sudden deaths.

Clinical case: An unusual manifestation of Strep suis infection

At least 25% of the pigs from 2 to 3 weeks old were reported to be lame, some so severe that they lay in the arcs shaking and unable to stand.

Interaction between PRRSV and Streptococcus suis

PRRSV favours the appearance of secondary infections like the one caused by S. suis due to the impairment of the alveolar macrophages cleaning functions.

Transmission of swine pathogens: a practical perspective

Pathogens that are transmitted mostly through direct, pig to pig, contact are generally contained with today’s biosecurity programs and pig flow strategies. However, pathogens using multiple routes of transmission seem to evade standard biosecurity programs.

Streptococcus suis - Zoonotic epidemic in Asia

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.

Differential diagnosis of nervous diseases in the pig

In the diagnosis of nervous conditions it is difficult to establish initially, whether the problems lie in the bones, joints, muscles, or tendons or nerves. We should rule out anatomical or pathological problems in the former four systems before we assume we are dealing with nervous system problems.

Dietary fibre as microflora modulator in pigs

Certain species of the resident bacteria are known to provide benefits to the host. These are the lactic acid producing bacteria (LAB), which include the Lactobacilli, Bifidobacteria, members of the Streptococci, and several other species. The amount and composition of substances reaching the large intestine can be readily modified by diet and, in terms of bacterial substrates, it is the fermentable substrate such as oligosaccharides, starches and non starch polysaccharides (NSP) which are most important.
