A new method for the experimental production of necrotic enteritis and its use for studies on the relationships between necrotic enteritis, coccidiosis and anticoccidial vaccination of chickens
TLDR
Immunization with a live, pentavalent, attenuated anticoccidial vaccine (Paracox-5), by virtue of its protection against clinical coccidiosis due to the E. maxima challenge, indirectly protected birds against a subsequent challenge with virulent C. perfringens.
Dose-response effects of diclazuril against pathogenic species of ovine coccidia and the development of protective immunity.
TLDR
It was concluded that when used as a metaphylactic treatment, diclazuril works rapidly and is effective within four days of administration in the control of coccidiosis in young lambs at pasture whilst allowing the development of protective immunity against subsequent heavy coccidia challenge.
Review article: coccidiosis of domestic ruminants.
TLDR
This paper seeks to review the current knowledge on the biology and control of the coccidial species affecting cattle, sheep and goats.
Giardiasis in lambs at pasture
Faecal samples from a group of lambs at pasture were screened at weekly intervals for nine weeks for the presence of Giardia species using a modified zinc sulphate flotation method. Fifty-nine of 86…
Detection of Cryptosporidium parvum using a specific polymerase chain reaction.
The design and use of polymerase chain reaction primers and probes as reagents for the detection of Cryptosporidium parvum are described. Sensitive and specific amplification of a 329 base pair…
Eimeria stiedai in rabbits: the demonstration of responses to chemotherapy.
TLDR
Only sulphaquinoxaline and Lerbek gave satisfactory control of this parasite and the latter formulation was more effective than either of its constituents used alone.
Experiments with defined multispecific coccidial infections in lambs.
The behaviour of four species of Eimeria was studied in lambs which were given either monospecific or multispecific infections. In the presence of other species the patency of oocyst production of E.…
Redescriptions of Eimeria irresidua Kessel & Jankiewicz, 1931 and E. flavescens Marotel & Guilhon, 1941 from the domestic rabbit.
TLDR
Eimeria flavescens and E. irresidua from the domestic rabbit are redescribed and are found to be pathogenic in young Dutch rabbits; even heavy infections produce only a transient pause in weight gain.
The occurrence of Eimeria weybridgensis and other species of coccidia in lambs in England and Wales.
TLDR
Ten species were identified, and 65 per cent of the specimens contained four to six species.
The pathogenesis of experimental infections of Cryptosporidium muris (strain RN 66) in outbred nude mice.
TLDR
Three groups of six-week-old nude outbred mice were orally infected with 400, 20,000 and 1,000,000 oocysts of Cryptosporidium muris (strain RN 66) per mouse, respectively and Histological examination revealed the presence of parasites confined to the glandular stomach.
