Twenty-nine intestinal spirochetes isolated from Australian aboriginal children and six strains from Italian adults (HRM1, -2, -4, -5, -7, and -14) were genetically examined at 15 enzyme loci by using multilocus enzyme electrophoresis. Results were compared with those previously obtained for 188 porcine intestinal spirochetes. DNA from human strain HRM7 and porcine strain Serpulina hyodysenteri...

In pigs it is used for treatment of dysenteria due to Serpulina hyodysenteriae at a dosage of 25 mg/kg/day for 4 days for therapy. For eradication of the disease in herds treatment for 7 days and a second treatment period of 5 days after 3-4 weeks is indicated. Metronidazole is intended for use in cows with retentio secundinarum in combination with neomycine administered as intra-uterine capsul...

The anaerobic spirochete Brachyspira hyodysenteriae is host to a bacteriophage-like agent known as VSH-1. VSH-1 is a novel gene transfer mechanism which does not self-propagate and transfers random 7.5kb fragments of host DNA between B. hyodysenteriae cells. In these investigations early events during VSH-1 induction by mitomycin C were examined. Quantitative PCR analysis revealed that VSH-1 hv...

Two intestinal spirochete isolates obtained from chickens with diarrhea were examined by electron microscopy, biochemical tests, rRNA gene restriction pattern analysis, and multilocus enzyme electrophoresis. One isolate (strain 91-1207/C1) was pathogenicity tested in vivo in chickens. The chicken spirochetes were morphologically indistinguishable from Serpulina innocens and Serpulina hyodysente...

A small Central Asian Noctuidae genus Palaeagrotis Hampson, 1907 is revised. One new species, P. adrienneae Volynkin, Gyulai & Behounek, sp. n. is described from South Mongolia. The lectotypes of Hadena inops Lederer, 1853 and Heterographa sibirica Staudinger, 1896 are designated. The adults, and the male and female genitalia are illustrated.

Jacobson, M. 2003. Enteric diseases in pigs from weaning to slaughter. Doctor’s dissertation. ISSN 1401-6257, ISBN 91 576 6387 4 The general aim of this thesis was to study enteric diseases in growing pigs, with special reference to diseases caused by Brachyspira hyodysenteriae and Lawsonia intracellularis. The occurrence of enteric diseases in “growers” is a problem of increasing importance in...
