The Use of Ultrasonography to Study Teratogenicity in Ruminants: Evaluation of Ipomoea carnea in Goats

Background: Ipomoea carnea (I. carnea) is a poisonous plant found in Brazil and other tropical countries that often poison livestock. The plant contains the alkaloids calystegines and mainly swainsonine, which inhibit cellular enzymes and cause systematic cell death. The objective of this study was to evaluate the perinatal effects of I. carnea in goats. Methods: Forty-seven pregnant goats were randomly allocated into 5 treatment groups and given the following doses (g/kg BW) of I. carnea: 0 (IC0), 1.0 (IC1), 3.0 (IC3), 5.0 (IC5) and 7.5 (IC7). The treatment animals were given fresh I. carnea from day 27 of gestation to parturition. Weight gains and serum biochemistry were evaluated. Fetuses were evaluated using ultrasonographic measurements. Results: Goats from the IC7 group showed clinical signs of poisoning. Ultrasound examination revealed that I. carnea feeding in all treatment groups reduced fetal movement compared to the controls. There was an increase in the total number of birth defects (retrognathia and arthrogyposis) in the IC7 and IC5 groups compared to the controls. Conclusion: The results show that I. carnea has teratogenic potential in goats. In addition, ultrasounds were useful in evaluating fetotoxicity and teratogenicity.

Representative Seroprevalences of Brucellosis in Humans and Livestock in Kyrgyzstan

Kyrgyzstan reported 77.5 new human brucellosis cases per 100,000 people in 2007, which is one of the highest incidences worldwide. In Kyrgyzstan, the currently used diagnostic tests in humans and animals are the Rose Bengal Test and the Huddleson test. A national representative cross-sectional study using cluster sampling proportional to size in humans, cattle, sheep, and goats was undertaken to assess the apparent seroprevalence in humans and animals. A total of 4,936 livestock sera and 1,774 human sera were tested in Naryn, Chuy, and Osh Oblasts. The overall apparent seroprevalences of brucellosis were 8.8% in humans (95% CI 4.5-16.5), 2.8% (95% CI 1.6-4.9%) in cattle, 3.3% (95% CI 1.5-6.9%) in sheep, and 2.5% (95% CI 1.4-4.5%) in goats. Naryn Oblast had the highest seroprevalences in humans and sheep. More men than women were seropositive (OR = 1.96; P < 0.001). Human seroprevalence was significantly associated with small ruminant seroprevalence but not with cattle seroprevalence. Annual incidence of human brucellosis exposure, measured by serological tests, was more than ten times higher than the annual incidence of reported clinical brucellosis cases. This indicates an under-reporting of human brucellosis cases, even if only a fraction of seropositive people have clinical symptoms. In conclusion, this study confirms the high seroprevalence of brucellosis in Kyrgyzstan and warrants rapid effective intervention, among others, by mass vaccination of sheep and goats but also of cattle.

Effects of induced parturition in goats on immunoglobulin G and chitotriosidase activity in colostrum and plasma and on plasma concentrations of prolactin

The effect of induction of parturition with a PGF(2)alpha analog on plasma concentration of prolactin (PRL) and its effects on colostrum concentration of IgG and chitotriosidase (ChT) activity were studied in 16 pregnant Majorera goats. Treated goats, those in which parturition was induced, had greater concentrations of PRL than control goats 24 h before parturition (P < 0.05) and 48 h after parturition (P < 0.05). Control goats had greater concentrations of PRL than treated goats 96 h after parturition (P < 0.05). Plasma concentration of IgG did not differ between groups during the experimental period, but colostrum concentrations of IgG were greater in control goats than in treated goats at parturition (P < 0.05). Plasma ChT activity decreased during the period 72 h before parturition to 24 h after parturition in control and treated goats. Time evolution after partum affected the colostrum ChT activity, being greater at parturition than after parturition in both groups (P < 0.05). In summary, concentration of IgG in colostrum is slightly diminished if parturition is induced. Induction of parturition causes an early increase in PRL, which is most likely responsible for preterm suppression of IgG transport into mammary secretions. (C) 2011 Elsevier Inc.

Echinococcus granulosus infection dynamics in livestock of Greece

An epidemiological and molecular survey on the occurrence of Echinococcus hydatid cysts in livestock was conducted in Greece. In total 898 sheep, 483 goats, 38 buffaloes, 273 wild boars and 15 deer were examined and 30.2% (6.45% cyst fertility), 7.86% (3.2% cyst fertility), 42% (7.9% cyst fertility), 1.1% (0% cyst fertility), 0% of them were found infected, respectively. Infection rate in different geographical regions varied between 26.1 and 53.8% (cyst fertility 2.04 and 34.6%) in sheep, 7.33 and 13.3% (cyst fertility 0 and 3.2%) in goats. Genotyping, based on cox1 and nad1 analyses, demonstrated the predominance of E. granulosus s.s. (G1 genotype). The presence of one single genotype-complex within a relatively large spectrum of intermediate host species in Greece indicates the presence of a dominant transmission dog-sheep cycle involving additional host species which may act as disease reservoir for human infections.
