Summary

Internal parasitism was studied in five flocks in different regions of the Yemen Arab Republic. Ewes and lambs were faeces sampled from the spring of 1977 to the spring of 1978 and helminth-free tracer lambs were subsequently run with three of the flocks from October 1978 to November 1979. The findings indicated that ovine helminthiasis and fascioliasis may be of importance with the following regional variations:

  1. (1)

    Haemonchosis all the year round in the Tihammah coastal plain.

  2. (2)

    Haemonchosis and trichostrongylosis in the periparturient period in the Southern Uplands and Western Foothills.

  3. (3)

    Fascioliasis and nematodiriasis in the Inter-Montane Plains of the Highlands.

Possible control regimes are suggested for further investigation.

Résumé

Le parasitisme interne a été étudié dans cinq troupeaux dans différentes régions de la République Arabe du Yémen. Des échantillons coprologiques des brebis et des agneaux ont été prélevés du printemps 1977 au printemps 1978 et des agneaux traceurs indemnes ont été ensuite introduits dans trois troupeaux d'octobre 1978 à novembre 1979. Les résultats montrent que les helminthoses et les fascioloses ovines peuvent avoir une certaine importance avec les variations régionales suivantes:

  1. 1.

    Les haemonchoses sont présentes toute l'année dans la plaine côtière de Tihammah.

  2. 2.

    Les haemonchoses et les trichostrongyloses sont présentes pendant la période se situant autour de la mise bas dans les plateaux du Sud et les basses collines de l'Ouest.

  3. 3.

    Les fascioloses et les nématodirioses sont présentes dans les plaines situées entre les montagnes des hautes-terres.

Des stratégies possibles de contrôle sont proposées pour une enquête plus poussée.

Resumen

Se estudió el parasitismo interno ovino, en cinco rebaños de diferentes regiones de la República Arabe de Yemen. Se examinaron muestras de materia fecal de ovejas y corderos, desde la primavera de 1977 hasta la de 1978, introduciendo posteriormente ovejas centinelas libres de helmintos en tres de los rebaños, a partir de Octubre de 1978 hasta Noviembre de 1979. Los resultados indicaron, que la helmintiasis y fascioliasis pueden adquirir importancia, de acuerdo a las siguientes variaciones regionales:

  1. (1)

    Hemoncosis, todo el año en las planicies costaneras de Tihammah.

  2. (2)

    Hemoncosis y tricostrongilosis, durante la época de pariciones en las tierras atlas sureñas y en las colinas occidentales.

  3. (3)

    Fascioliasis y nematodiriasis, en los valles inter-montañosos.

Se sugieren posibles regímenes de control para investigaciones futuras.
