background: encephalitozoon cuniculi is a microsporidian parasite commonly found in rabbits that can infect humans, causing encephalitozoonosis. our objective in this study was to evaluate the seroprevalence of this parasite in rabbits and humans in china. methods: overall, 300 serum samples each from clinically healthy rabbit and hu-man were collected from three regions of china (sichuan provi...

Sarcoptes scabiei infests a wide variety of mammals including domestic, farm and wild animals. Different varieties of S. scabiei are considered to be strictly host specific. However, some reports indicate that the parasite is not completely host specific. In the current study the dog strain (S. scabiei var. canis) was experimentally transmitted to domestic rabbit, Oryctolagus cuniculus. The bac...

Microscope observations of rabbit zygotes demonstrate that a sperm aster forms in association with the male pronucleus approximately 1 h postinsemination and consists of two regions. One, the centrosphere, contains a dense aggregation of cisternae of smooth endoplasmic reticulum and microtubules. The second consists of fascicles of microtubules which emanate from the centrosphere. Fertilized ra...

IN previous papers it has been shown that high concentrations of oxygen are able to exert on growing retinal vessels a peculiar type of constrictor action which progresses gradually to complete obliteration of the ingrowing complexes (Ashton and others, 1953, 1954). The possible factors involved in this mechanism have already been fully discussed; it is the purpose of this paper to report preli...

Onderstepoon Journal ofVeterinory Research, S3, 181-185 (1986) Employing rabbit immune serum, 10 flaviviruses known to be present in South Africa could be divided into S serological subgroups. The subgroups conform to the general pattern described for the group. Sera from experimentally infected calves...

An interaction between actinand myosin-like proteins and its implication in cellular motilities have been suggested in a variety of cells other than muscle (reviewed by Taylor, 1972, and by Rebhun, 1972) . Actually, those proteins have been extracted and purified from certain kinds of cells . They may be located mainly in the cell cortex (Ishikawa et al ., 1969) . In sea urchin eggs, although a...

Rabbit zonae pellucidae were isolated using a modified technique of Dunbar et al. (1980). Zonae pellucidae were solubilized in saline phosphate buffer (pH 7.8) for 30 min at 70 degrees C. One dimensional SDS-PAGE analysis showed that zona pellucida is essentially composed of three major proteins with apparent molecular weights of 200 (275-165) kd, 100 (135-96) kd and 75 (96-51) kd. Preincubatio...

Laying chickens normally produce a riboflavin-binding protein (RBP) essential for the transfer of vitamin B2 to the egg. A mutant line of chickens (rdrd) is incapable of synthesizing functional RBP. The rdrd laying hens contain a component in the liver and the magnum of the oviduct which cross-reacts with rabbit antiserum specific for RBP. No crossreacting material (CRM) was observed in eggs or...

The effect of homograft sensitization of a mother against her fetuses has been studied. A female rabbit was repeatedly grafted from both members of a breeding pair. Their offspring should and do become objects of homograft sensitization induced in the female by grafts from the parents. After sensitization was established, fertilized ova were transplanted from the breeding pair to the sensitized...
