JOURNAL FREE ACCESSCats and dogs in the Yokohama area of Kanagawa Prefecture were examined for the presence of Toxoplasma antibody by the dye test. They were divided into two groups, A and B. Group A was that of animals which were healthy and had never manifested any of the symptoms characteristic of toxoplasmosis. Group B was that of animals which had ever exhibited at least one of such symptoms.
1. Among the house dogs tested, the positive rate (1: 16 and higher) was 29.3 per cent (113/386), or 19.8 per cent (44/222) in group A and 42.1 per cent (69/164) in group B. Group B showed a much higher positive rate (X2=22.6) and included more animals revealing high antibody titers than group A.
Such tendency as mentioned above was common to three age groups (less than 1 year, 1 to 5 years, and more than 5 years), being particularly noticeable among young puppies. The positive rate increased almost parallel to the advance in age in group A, but it was constantly high, regardless of age, in group B. It presented no difference by sex.
2. Of the symptoms manifested in group B, the most important were digestive disorders, particularly watery and bloody diarrhea. Secretion in excess of sebum palpebrale, coughing, and pneumonia were also seen.
3. The ownerless dogs tested gave a positive rate of 42.6 per cent (20/47). This rate was higher, but not significantly higher, than that among the house dogs.
4. The cats tested revealed a positive rate of 46.9 per cent (15/32), which was higher than that among the house dogs. There was a tendency that the rate was higher in group B than group A in the cats. Cats showing antibody titers higher than 1: 256 were found in 8.7 per cent in group A and 44.4 per cent in group B. Noticeable symptoms were paralysis of the hind quarter, chronic diarrhea, and persistent fever in catsView full abstractDownload PDF (1355K) -

JOURNAL FREE ACCESSOn May 13, 1963, a five-year-old dairy cow gave premature birth to a litter of five, two males and three females. They were calved about 25 days earlier than expected, but were allhealthy.
The three females were normal in outward appearance. Autopsy of each of them disclosed, however, that the uterus and vagina suffered from hypoplasia and that the gonad was an ovotestis histologically.
Therefore, they were presumed to be devoid of reproductive capacity.View full abstractDownload PDF (4661K) -

JOURNAL FREE ACCESSA 3-day-old female dog possessed two right posterior limbs. This anomaly could be termed dipygus tripus (Potter, 1957).
In addition, this animal showed a variety of internal and external anomalies, which were examined macroscopically and histologically.
Roentgenographic observations were also made by the use of a Softex super soft roentgen apparatus. After that, the skeleton of this animal was stained by DAWSON'Sa lizarin red S method.
1. In the ventral pelvic region, two external genital openings were found under the anus. At dissection, it was found that the large intestine was duplicated into two cecums and two sets of colon and rectum. One set of colon and rectum reached the anus and appeared normal. The other set ended to form a ligament extending to the right external genital opening, and appeared extra. The female internal genital organs opened to the left external genital opening. An extra duct-like urinary bladder was present, extending from the right side of the normal bladder to the left side of the extra large intestine.
2. Skeletal observations revealed the presence of two right ossa coxae, one of which seemed normal and the other extra. The normal ossa coxae joined at the acetabulum with the femur of the extra right posterior limb, whereas the extra ossa coxae joined with the femur of the normal right posterior limb. In addition, the extra limb contained various abnormal bones.View full abstractDownload PDF (8091K) -
