Title: Valpotić, I., Franković, M., Vrbanac, I.:, Identification of infant and adult swine susceptible to enterotoxigenic Escherichia coli by detection of receptors for F4 (K88)ac fimbriae in brush borders of feces.

Summary: We attempted to determine F4(K88)- adhezive and non adhesive phenotipes of infant (neonatal 3 day old and weaned 4 week old pigs) and adult (6 month old) swine by ELISA using immobilized F4 (K88) as fimbrial antigen or whole F4 (K88)+E coli cells( strains M1823 and 1476) and isolated small intestinal brush borders or easily-obtainable fecal samples from the same animals.Nineteen of 22 neonates (86%), 17 of 20 weaners (85%), and 26 of 39 adults (67%) were classified identically as (F4( K88) receptor-positive or negative by the ELISA.The ELISA with feces from adult swine was found to be almost equally specific (87%) as that with feces from neonatal(90%) and weaned (91%) pgs. However, the sensivity of the assay was low (38%), indicating that fecal samples from adults contained lessreceptor-material than necessary for comparable phenotyping.The receptor positive ofbrush borders from neonatus and weaners reacted significantly better(P 0.02,P 0.001 respectively) with purified F4(K88) antigen than did those from adults.There was good agreement between the average ELISA values for feces from infant and adult swine regardless the source of coating antigen applied. With this assay we can determine F4(K88) phenotypes of infant swine using easily-collected fecal samples rather than isolated brush borders. It was also concluded that tested feces is not an acceptable alternate source in the receptor-material to brush borders from F4(K88) susceptible adult swine.

Title: N. Vijtiuk, S. Ćurić, G. Lacković, I. Udovičić, I. Vrbanac and I. Valpotić: Histopothological Features in the Small Intestine of pigs Infected with F4ac+ Non-enterotoxigenic or Enterotoxigenic Strains of Esherichia coli

Summary: Four porcine strains of Escherichia coli were examined for their effects on the small intestine of 4-week-old weaned pigs infected orogastrically.The strains used experimentaly were: strain 1467 (adhesin negative, non-toxogenic); strains 2407 and 1466 (adhesin positive, non-toxogenic), derived by genetical engeneering from strain 1467 and containing a wild type plasmid and a recombinat plasmid, respectively, encoding, the F4 antigen (adhesin);and strain MI1823 (adhesin positive, toxigenic). In addition, 2 week-old pigs that died from natural colibacillosisassociated with two strains ("Ihan I and 2" adhesin positive, toxigenic) were examined.Strain M1823 and the Ihan strains produced moderate and marked lesions,respectively.Strain 1467 did not cause mucosal damage or an inflamatory response.Strains 1466 and 2407 caused a mild to mederate leucocyte (mononuclear and polymorphonuclear) infiltration in the jejunal (but not ileal) lamina propria. However, unlike strain 1466, strain 2407 did not cause damage to the small intestinal mucosa and should be further studied as a potential oral vaccine strain for post-weaning E. coli diarrhoe.

Title: Ivan Vrbanac, Tomislav Balenović, Rayane Yammine, Ivica Valpotić, Boris Krsnik : Preweaning losses of piglets on a State farm in Bosnia and Herzegovina

Summary: The objective of a 3 year pilot survey of preweaning mortality on large swine in Bosnia and Herzegovina was to provide producersand/or veterinarians with information about causes of piglet losses , their occurence and frequency at the herd (regional) level.This may also serve as a model for an assesment at the national level.The SNOVET systeme, a part of the National Animal Health Monitoring system (launched in the USA in 1985),was applied for the classification of causes of death among suckling piglets based on postmorten findings.To asses the incidences of causes of preweaning losses, 354 094 piglets born in 34 682 litters were monitored daily from june 1985 to May 31. 1988. Respective information from 20 682 (or 5.8%)stillborns and those piglets that died from birth to weaning (49 058 or 14.7%) was given.Among piglets born alive, overlaying was the most frequent cause of death (6%), followed by mortalty due to gastrointestinal syndrome (3.9%), cahexia/inanitio neonatorum (2.2%), and losses of small or deformed piglets (1.6%). The incidence of pneumonia was very low (0.02%).A relatively high proportionof causes of mortality remained unknown (0.9%) partly owing to savaging or losing piglet corpses in the sewers.The use of recorded information on type, extent, and incidence of piglet mortality (gathered on the sample of appropriate size) on long-term basis may help in the development of effective strategies to reduce/control losses until weaning.
