Land snail identification researches in Iraq is limited. In Erbil-Iraq, a study was carried out to explore the identification of various land snails. In earlier studies, most species determination was based on shell morphology, anatomy of genitalia, and mantle color, these criteria are continuously applied to describe new species/new records. S...

Extensive production of Neospora caninum tissue cysts in a carnivorous marsupial succumbing to experimental neosporosis King et al. Abstract Experimental infections of Sminthopsis crassicaudata, the fat-tailed dunnart, a carnivorous marsupial widely distributed throughout the arid and semi-arid zones of Australia, show that this species can act as...

Summary of body weights and tail diameters for experimental animals.

Sequence alignment of known Neospora caninum MS10 trinucleotide repeats.

Summary of food consumption for experimental animals.

The aim of this study was to describe the first development and evaluation of a multiplex tandem PCR (MT-PCR) assay for the detection and identification of 4 common pathogenic protozoan parasites, Cryptosporidium spp., Dientamoeba fragilis, Entamoeba histolytica, and Giardia intestinalis, from human clinical samples. A total of 472 fecal samples su...

Neospora caninum is a coccidian cyst-forming parasite found in a wide range of host species such as mice, dogs and cattle. The development of methods such as vaccines to prevent abortion and fetal loss due to neosporosis would be greatly assisted by further knowledge on immunity and host responses to infection. In this study we used microarray tech...

Neospora caninum is a parasite regarded a major cause of foetal loss in cattle. A key requirement to an understanding of the epidemiology and pathogenicity of N. caninum is knowledge of the biological characteristics of the species and the genetic diversity within it. Due to the broad intermediate host range of the species, worldwide geographical d...

To provide objective data on the potential role of dingoes (Canis lupus dingo) in the life cycle of Neospora caninum in Australia, the production of N. caninum oocysts by experimentally infected canids was investigated. Three dingo pups raised in captivity and three domestic dogs were fed tissue from calves infected with an Australian isolate of N....

Genetic diversity of Neospora caninum was investigated through a study of repetitive sequences found in the genome of this species. Twenty different loci were studied, and three were identified that varied in repeat content amongst isolates. No relationship was found between the copy number of repetitive sequences present and host type or geographi...

Infection with Neospora caninum is regarded as a significant cause of abortion in cattle. Despite the economic impact of this infection, relatively little is known about the biology of this parasite. In this study, mini and microsatellite DNAs were detected in the genome of N. caninum and eight loci were identified that each contained repetitive DN...

Toxoplasma gondii was isolated from the brain of a young dog for the first time in Australia. The identity of the parasite was confirmed by PCR, Western blotting, electron microscopy and cat bioassay. Genotyping of the isolate (TgDgAu1) was determined by PCR-RFLP markers that showed it to be a Type II strain. Western blotting demonstrated the prese...

The development of a novel nested polymerase chain reaction is described and used for detecting the presence of Neospora caninum and Hammondia heydorni DNA in DNA extracted from feral rodent tissues. A unique strategy was used for design of an assay that could be adapted for detecting DNA from more than one member of Toxoplasmatinae simultaneously...

Hamelin Pool in Western Australia is home to distinctive shallow-water marine benthic communities dominated by stromatolites-structures formed by bacterial assemblages. We have sought to establish if the principal consumers of bacteria, the flagellates, form a distinctive community. We present observations of 87 species of flagellates, of which thr...
