Comparison of virulence gene profiles of Escherichia coli strains isolated from healthy and diarrheic swine

Article Abstract:

The virulence genes (VGs) repertoire of 23 commensal Escherichia coli isolates from healthy pigs and 52 clinical isolates associated with porcine neonatal diarrhea and postweaning diarrhea was analyzed. A combination of uni- and multiple PCR assays targeting 58 VGs associated with Escherichia coli strains causing intestinal and extraintestinal disease in humans and other mammals was used. The virulence genes associated with each pathotype contribute to its functionality in causing characteristic symptomatology that typifies the disease syndrome rather than defining each pathotype.

Optimization of a sampling system for recovery and detection of airborne porcine reproductive and respiratory syndrome virus and swine influenza virus

Article Abstract:

An objective of optimizing sampling parameters is presented for increased recovery and detection of airborne porcine reproductive and respiratory syndrome virus (PRRSV) and swine influenza virus (SIV). Results showed that specific compounds influenced the likelihood of identifying PRRSV and SIV in collection medium.

Identification of a novel Cryptosporidium genotype in pigs

Article Abstract:

Research reveals the occurrence of a new genotype of Cryptosporidium in pigs, pig genotype II, in addiion to the known pig genotype I as determined by 18S ribosomal DNA analysis.
