Early administration of canine parvovirus monoclonal antibody prevented mortality after experimental challenge.

Objective: To evaluate the effectiveness of canine parvovirus monoclonal antibody (CPMA) as a treatment against canine parvovirus (CPV-2)-induced mortality and to support USDA product licensure.

Animals: 28 purpose-bred Beagle dogs aged 8 weeks were randomized to the treated (n = 21) or control (7) group.

Methods: Dogs were challenged intranasally with 104.

Immunogenicity and protective efficacy of a single-dose live non-pathogenic Escherichia coli oral vaccine against F4-positive enterotoxigenic Escherichia coli challenge in pigs.

Enterotoxigenic Escherichia coli strains expressing F4 (K88) fimbriae (F4-ETEC) are one of the most important causes of post-weaning diarrhea (PWD) in pigs. F4, a major antigen, plays an important role in the early steps of the infection. Herein, the efficacy of a live oral vaccine consisting of a non-pathogenic E.

Swine waste treatment by self-heating aerobic thermophilic bioreactors.

Pig manure represents a very high-strength wastewater that is well suited for a self-heating aerobic thermophilic treatment. Here we report the use of 59-L Aerobic Thermophilic Sequencing Batch Reactors (AT-SBR) to study the treatment of pig manure with a HRT of 6 days. Temperatures up to 75 degrees C were reached without external heating by using Venturi-type aerators but these conditions were detrimental for the respiratory activity of the microflora.
