Porcine Health Management

Antimicrobials (AB) are essential tools to control clinical outbreaks involving bacteria as primary or secondary pathogens. The selective pressure exerted by these compounds could contribute to the emergence of antimicrobial resistant (AR) bacteria. The...

The objective of this project was to eradicate Mycoplasma hyopneumoniae (Mh) from a 400 outdoor sow farm, using antibiotic treatment in the breeding animals and offspring and with a partial depopulation. Tylvalosin was selected as the preferred antibiotic...

Gilts are considered key in Mycoplasma hyopneumoniae (Mhyo) transmission. Vaccination during gilt acclimation may decrease shedding at farrowing, piglet colonization and, together with piglet vaccination, to diminish the impact of respiratory problems in...

Mycoplasma hyopneumoniae (Mhyo) strains circulate in most vaccinated farms. Nevertheless, there is few information regarding the similarity among field and vaccine strains.  The purpose of this study was to compare the Mhyo genotype of the strains...

Post-weaning diarrhea (PWD) remains a major cause of economic losses for the pig industry. A number of preventive measures have been recommended to control PWD. Coliprotec® F4/F18 is a live non-pathogenic E. coli vaccine for active immunization of pigs...

Enzootic pneumonia remains one of the major respiratory diseases of pigs affecting significantly the growth performance of fatteners. In some production systems the vaccination is used for practical reasons even before weaning in suckling piglets. The aim...

Streptococcus (S.) suis is a major swine pathogen which causes considerable losses in the swine industry. S.suis possesses a coat of capsular polysaccharides that confers protection against the immune system. This capsule helped to classify S. suis...

App causes important losses to the pig industry through respiratory disease and >30% mortality in growing pigs if left untreated. App infection does not always produce disease and asymptomatic carriage in the tonsil  may be difficult to detect. Recent...

Streptococcus suis is associated with disease and mortality in young piglets from weaning to 10 weeks old. To study interventions appropriate animal models need to be available. Therefore, an infection experiment with a pathogenic clinical Streptococcus...

Neonatal diarrhea is common in pig farms and induces economic losses because of poor technical performances and increased mortality of the affected piglets, as well as increased frequency of antimicrobial use. The aim of this study was to establish the...

Econor® is a pleuromutilin antibiotic registered for treatment of enteric and respiratory diseases associated with Brachyspira spp, Lawsonia intracellularis and Mycoplasma hyopneumoniae. The objective of the work was to compare the pharmacokinetics (PK)...

Introduction Econor® is a pleuromutilin antibiotic registered for treatment of enteric and respiratory diseases associated with Brachyspira spp, Lawsonia intracellularis and Mycoplasma hyopneumoniae. The objective of the work was to compare the...

Mycoplasma hyopneumoniae is the primary pathogen of Enzootic Pneumonia and can predispose to the porcine respiratory disease complex. Vaccination is commonly used to reduce coughing, lung lesions and performance losses due to Mycoplasma hyopneumoniae...

A modified elimination protocol of Mycoplasma hyopneumoniae (M. hyo) compared to the method described by Zimmermann, W. 1989 is reported. Material and Methods 900 Danbred sows and 350 Danbred gilts were planned eliminated for M. hyo. The herd is located...

In France, urinary tract infections (UTI) in sows can affect the breeding performances, particularly fertility, and sometimes lead to mortality of sows.  Such infections are often under or late diagnosed. Subsequent economic losses raise awereness of...
