Gastrointestinal parasites in goats from Monte Castelo, Santa Catarina, Brazil / Parasitas gastrintestinais em caprinos de Monte Castelo, Santa Catarina, Brasil

This study was carried out with the aim of estimating the degree of gastrointestinal helminth infection in goats on the Northern Plateau of Santa Catarina. Twelve young females and 11 adult females were used. Every 28 days, feces samples were taken to quantify the nematode eggs per gram of feces (EPG). Larval culturing was performed on a pool of positive samples from the same group. The fecal egg counts (FECs) ranged from zero to 10,400 EPG in the young group and zero to 7,600 EPG in the adult group. The mean FECs were between 583.3 and 4441.7 in the young group and between 418.2 and 2181.8 in the adult group. Eggs of the order Strongylida and genera Moniezia and Toxocara, and oocysts of Coccidia, were observed. The young animals were more affected and Haemonchus was the most prevalent genus in the samples.

Este trabalho foi realizado com o objetivo de estimar o grau de infecção dos helmintos gastrintestinais em um rebanho caprino criado no Planalto Norte Catarinense. Foram utilizadas 12 fêmeas jovens e 11 adultas, das quais, a cada 28 dias, foram coletadas amostras de fezes diretamente do reto, totalizando 12 coletas, para quantificação de ovos por grama de fezes (OPG) e cultivo de larvas através de "pool" das amostras positivas do mesmo grupo. A contagem de OPG variou de zero a 10.400 nos animais jovens e de zero a 7.600 nos adultos. As médias do OPG entre as coletas foram de 583,3 a 4.441,7 no grupo jovem e de 418,2 a 2.181,8 nos adultos, sendo observados ovos da ordem Strongylida, dos gêneros Moniezia e Toxocara, bem como oocistos de coccídeos. Os animais mais jovens foram os mais acometidos, sendo o gênero Haemonchus o mais prevalente.

Prevalence of cestode parasites in sheep slaughtered in Riyadh city, Saudi Arabia

Prevalence of tapeworm infections among sheep slaughtered in Riyadh City were studied from February 2007 to March 2008. A total of 76 out of 3300 sheep were infected with adult cestodes [2.3%]. The highest infection rate was in autumn [8.1%], and the lowest one was in summer [1.7%]. The cestodes were identified as Moniezia expansa [96.3%] and M. deuticulata [3.7%]. Concerning seasonal dynamics of the worms, the highest number was recorded in October and November [13.5 and 8.3%], while the lowest one was in June and July [0.7 and 1.3%]. The examination of muscle samples from rump, shoulders and thigh of 1001 sheep revealed Cysticercus ovis in 120 sheep [12%]. The highest infection rate [17.5%] was in autumn, and the lowest one [6.2%] was in summer

endoparasites of sheep and goats, and shepherd in north Sinai governorate, Egypt

The examination of sheep and goats in four areas in North Sinai revealed an overall infection of 12.70% with Fasciola species, 11.8% with Paramphistomum cerve, 12.80% with Moniezia expansa, 47.11% with Trichostrongylus colubriformis, 4.59% Trichuris ovis and 44.85% Coccidia. The highly infected sheep and goats were diagnosed in El- Hassanah Center [90.49%], followed by El-Arish City [87.31%], then Rafah City [74.39%] and lastly Bir El-Abd [54.71%]. The elevation of the overall percentage of infection in the four areas was due to Coccidia infection, as this parasite was showed a concomitant infection in nearly all animals. On the other hand, the examination of 15 of the shepherds revealed Ascaris lumbricoides in 5, T. colubriformis in 3, Fasciola in one, Giardia lamblia in 10 and Coccidia in 3. Double and rarely triple infection was seen. The correlation between parasitic infections in sheep and goats as well as their shepherd was discussed

Molecular identity of major cross-reactive adult antigens in Fasciola gigantica, Toxocara vitulorum and Monieza expansa

Cross reactivity between Fasciola gigantica, Toxocara vitulorum and Moniezia expansa, whole worm extracts was proved by ELISA. Intense cross-reaction was observed between F. gigantica and M. expansa rather than between each of them and T. vitulorum. As judged by immunoblot, the cross-reactive antigens in F. gigantica which recognized by T. vitulorum antisera was 109 kD, while this component in addition to another one of 52 kD were detected by M. Expansa sera in the same extract. Furthermore, T. vitulorum antigen which cross-reacted with F. gigantica, was 133 kD and with M. expansa was 143 kD. Antigens responsible for cross-reactivity in M. expansa were 130 kD and 210 kD to T. vitulorum and F. Gigantica, respectively

Structural characterization and immunolocalization of egg antigens cross react with Toxicara vitulorum, Fasciola gigantica and moniezia expansa mature flukes

A structural homology between eggs of Toxocara vitulorum, Fasciola gigantica and Moniezia expansa was proved by the use of SDS-PAGE. In immunoblot, nine, eleven and seven polypeptides were recognized in F. gigantica, M. expansa and T. vitulorum eggs, respectively, by their respective rabbit anti-adult antisera. Moreover, components of 240 KD and 206 KD were recognized in the three eggs by different anti-adult antisera. The anatomic localization of the cross-reactive epitopes in eggs was determined by indirect immunofluorescence microscopy. The cross- reactive epitopes were mainly associated with embryonated cells of F. gigantica, egg shell, larvae and vitelline membranes of T. vitulorum and egg shell and granular layer of M. expansa
