Ruminants
Abstract
We employed a population genomic approach to investigate the molecular basis of ruminant host adaptation by S. aureus. The data suggest that the common pathogenic clone associated with small ruminants originated in humans but has since adapted to its adopted host through a combination of allelic div...

Abstract
Anaplasma ovis is an intraerythrocytic rickettsial pathogen of small ruminants. Loop-mediated isothermal amplification (LAMP) is a nucleic acid detection method in which the target DNA can be efficiently amplified with high specificity and sensitivity under isothermal conditions. In this study, a LAM...

Abstract
We investigated how observed variation in the prevalence and intensity of parasite egg or oocyst shedding in four co-occurring ungulate species may reflect underlying seasonal variation in transmission and host immunity. This study was conducted July 2005-October 2006 in Etosha National Park, Namibi...

Abstract
The epidemiology of human campylobacteriosis is complex but in recent years understanding of this disease has advanced considerably. Despite being a major public health concern in many countries, the presence of multiple hosts, genotypes and transmission pathways has made it difficult to identify an...

The aim of this study was to determine whether foxes might act as definitive hosts of Sarcocystis alces in moose. In 2 experiments, 6 silver foxes (Vulpes vulpes) and 6 blue foxes (Vulpes lagopus) were fed muscle tissue from moose containing numerous sarcocysts of S. alces, and euthanazed 7-28 days...

Abstract
No animals were seropositive for IgM against RVFV. Of the animals born after the 1997-1998 epizootic, 18% (34/188) of sheep were seropositive for IgG against RVFV, compared with 3% (2/75) of goats. Seventy percent (8,144/11,678) of the mosquitoes collected were of the Culex subgenera; 18% (2,102/11,...

Chronic wasting disease (CWD), an important emerging prion disease of cervids, is readily transmitted by intracerebral or oral inoculation from deer-to-deer and elk-to-elk, suggesting the latter is a natural route of exposure.

The two commercial ELISA were more sensitive than the CFT in all panels from infected ruminants. However, they could only detect IgG. The I-ELISA should be the serological test method of choice for cattle, sheep and goats for import testing of animals into New Zealand because it was more sensitive t...

Abstract
In 2007, greenhouse gas (GHG) emissions in New Zealand were 16% higher than in 1990. Agriculture accounts for 48% of GHG emissions in New Zealand, and 10-12% of emissions in most other 'developed' countries. Methane (CH4) accounts for 35% of GHG emissions in New Zealand, mostly from ruminal fermenta...
