Phytogenic feed additive blend on Lawsonia intracellularis infection in pigs
Supplementing a phytogenic feed additives in pig diets may be an effective way control diarrhea promoted by Lawsonia intracellularis infection.
Ileitis vaccination – A tool to reduce the need for antibiotic treatment
In the coming years, the use of antimicrobials will be more closely regulated, following the guidelines set by the WHO in its global report on antimicrobial resistance in 2014.
Treatment strategies for intestinal diseases in weaned piglets
Single animal treatment or batch medication? in any case, the treatment and choice of medication should be done based on resistance testing.
Changes in the porcine intestinal microbiome in response to infection with S.enterica and L. intracellularis
There were similar changes in the GI microbiome associated with carriage of S. enterica regardless of whether the pigs were experimentally challenged with S. enterica or acquired it naturally.
Differential diagnosis of post-weaning diarrhoea in pigs
An accurate diagnosis is sometimes difficult because of the common occurrence of mixed infections, the compounding effects of environment and nutrition and the difficulties experienced in isolating and identifying all the possible pathogenic agents involved.
How does PCV2 contribute to enteric problems?
Recently, PCV2 has been suggested as a pathogen able to induce diarrhoea in pigs, and PCV2-enteric disease (PCV2-ED) as a separate entity within porcine circovirus diseases (PCVDs) has been proposed.
The influence on performance in fattening pigs of L. intracellularis and PCV2 infections as measured in feces by Q-PCR
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.
Pathogen presence in feral pigs and their movement around two commercial piggeries in Queensland, Australia
The presence of pathogens in feral pigs in such close proximity to commercial piggeries could pose a biosecurity risk.
Association between average daily gain, faecal dry matter content and concentration of Lawsonia intracellularis in faeces
Increasing numbers of L. intracellularis log10 bacteria/g faeces were significantly associated with decreasing average daily gain.
Clinical case: Impact of clinical and subclinical forms of ileitis on the same fattening farm
Ileitis can take different forms, and it is frequent that a subclinical and a more severe and clinical form coincide.
