Extract

Herd-health programmes have featured in NZVA Presidential addresses in recent years. Conferences have been opened by politicians stressing their importance and fanners, farm advisers and veterinary practitioners are discussing the concept. More or less intensive practical herd-health schemes are operating in many parts of New Zealand. The best known are in the Bay of Islands, at Wairoa and in Waipukurau.  相似文献

The present work describes myxozoans found in Cyphocharax nagelli (Characiformes: Curimatinae) commonly called "sagüiru" collected from Rio do Peixe Reservoir, S?o José do Rio Pardo, S?o Paulo, Brazil. From a total of 38 examined fish, 24 were infected with Henneguya garavelli n. sp. (63% prevalence) and two with Myxobolus peculiaris n. sp. (5% prevalence) in the gills. Spores were studied by staining and fresh spores were observed by differential interference contrast optics. Henneguya garavelli n. sp. differs from Henneguya iheringi, Henneguya occulta, Henneguya cesarpintoi, Henneguya santae, Henneguya pisciforme, Henneguya amazonica, Henneguya striolata, Henneguya leporinicola and Henneguya chydadea in spore length and from Henneguya travassosi, Henneguya adherens, Henneguya malabarica, Henneguya piaractus and also Henneguya chydadea in polar capsule length and tail length. Myxobolus peculiaris n. sp. was very different when compared to other species of Myxobolus in its morphology and the biggest size of spore body. The authors present tables with comparative measurements of Brazilian myxozoan parasites.  相似文献
