Extract

In order to utilize spring growth efficiently under a system of grassland farming, a New Zealand dairy farmer endeavours to calve as many cows as possible within a four to six weeks' period. To maintain this calving pattern, herd members must conceive by 70 to 80 days after calving. Consequently normal postparturient uterine involution, together with a minimum of delay in the onset of ovarian activity and oestral cyclicity, is of vital importance. A study of these phenomena may be very rewarding in helping to achieve optimal reproductive efficiency.  相似文献

Equine rhinopneumonitis virus infection in New Zealand

Abstract

Extract

Sir,—Japanese workers (Matumoto el al., 1965 Matumoto, M., Ishizaki, R. and Shimuzu, T. 1965. Serologic survey of equine rhinopneumonitis virus infection among horses in various countries. Arch, f. Viruslorsch., 15: 609–624.  [Google Scholar]) have examined 388 horse sera from 17 countries including New Zealand and have found evidence of a high incidence of infection with equine rhinopneumonitis virus. The New Zealand material was supplied between 1957 and 1960, by Dr J. D. Manning, then of the National Health Institute, Wellington.  相似文献   

Surveillance for highly pathogenic avian influenza in migratory shorebirds at the terminus of the East Asian-Australasian Flyway

AIM: To determine if migratory birds arriving in New Zealand in the Southern Hemisphere spring of 2004 were infected with the highly pathogenic avian influenza (AI) virus, H5N1.

METHODS: Cloacal and faecal samples were collected from migratory red knots following their arrival in New Zealand in October 2004. Two species of resident sympatric birds, wrybill and mallard duck, were sampled prior to, and following, the arrival of migratory birds.

RESULTS: No AI viruses were isolated from migratory or resident shorebirds. Non-pathogenic AI viruses were isolated from six resident mallard ducks, comprising the endemic subtypes H4 (n=2), H7 (non-pathogenic), H10, and H11 (n=2).

CONCLUSIONS: Highly pathogenic AI H5N1 virus was not detected in migratory shorebirds or sympatric water birds in the Firth of Thames, New Zealand, in 2004-2005, despite the possible proximity of migratory birds to outbreaks of the disease in East Asia in 2004.  相似文献

Sarcocysts morphologically similar to Sarcocystis muris were observed in the skeletal muscles of mice dosed with free isosporan sporocysts recovered from the faeces of naturally infected cats. Kittens fed these mice shed similar sporocysts measuring 8.7 ±0.1 x 10.8 ±0.1 μm in their faeces five to six days later. Feeding these sporocysts to mice and rats resulted in the formation of identical sarcocysts in mice, but not rats. Attempts to induce similar infections in mice using naturally acquired isolates of I. felis were unsuccessful.  相似文献
