JOURNAL FREE ACCESSWhen a calf became Paroxysmal Hemoglobinemia (-uria) by voluntary exces-sive water intake in extremely short period of time, the increment of plasma Fe conc.which normally indicates the degree of hemolysis, and the drop of plasma osmotic pressurein jugular vein were found not simultaneous. But, when dogs, a sheep and a calf wereintubated with water as much as 5% of respective body weight to their intestine, all animalsbecame hemoglobinernia, and in their mesenteric veins the reduction of plasma osmoticpressure and plasma Na and Cl conc. occurred nearly at the same time with the incrementof plasma Fe conc. The degree of the hemolysis and the drop of plasma osmotic pressurein mesenteric vein indicated similar trend to the results of in vitro exp. in which water ofvarious quantity was added to the whole blood. When a dog was intubated with normalsaline as much as 5% of its body weight to the intestine, the blood showed neither hemolysisnor decrement of plasma osmotic pressure in mesenteric, portal and jugular veins. Fromthese results, it was concluded that the hemolysis on Paroxysmal Ilemoglobinemia (-uria)could be caused by temporary extreme drop of plasma osmotic pressure in capillary veinswhere water was absorbed.View full abstractDownload PDF (850K) -

JOURNAL FREE ACCESSTwenty-nine pigs were inoculated subcutaneously with live vaccine preparedfrom the acriflavine-fast attenuated Koganei strain of Erysipelothrix rhusiopathiae. All ofthem survived against intradermal challenge with virulent culture 1 /2, 1, 2, 3 or 4 monthsfollowing vaccination. Five unvaccinated control pigs died after challenge, except onewhich showed severe clinical symptoms. In the vaccinated pigs, the growth agglutination(GA) titer in the serum began to rise on the 5th day after vaccination and reached amaximum on the 10th or 15th day. Then it dropped gradually up to 40 days after vac-cination. After that, it remained at almost the same level. It did not rise significantly bychallenge made within 2 months after vaccination, but rose clearly by challenge made 3 or4 months after vaccination, regardless of GA titer before challenge and manifestation ofa local skin reaction at the site of challenge inoculation. There was a good correlationbetween the highest GA Liter in the serum of each pig in the early stage after vaccinationand the intensity of skin reaction in the pig to challenge made in various stages aftervaccination. Therefore, it was concluded that the highest GA titer in the early stage aftervaccination might indicate the duration of immunity in pigs. Vaccinated pigs having a GALiter of 8 or below before challenge exhibited some distinct clinical reaction to challenge.Vaccinated pigs having a GA titer of 16 were resistant to challenge, with no or some reac-tion. On the other hand, vaccinated pigs having a GA titer of 32 or above presented noclinical reaction to challenge.View full abstractDownload PDF (710K) -

JOURNAL FREE ACCESSA seroepizootiological survey was performed on antibodies against bovineleukemia virus (BLV) in beef cattle in the Hida district by using the immunodiffusion testwith BLV glycoprotein antigens. These cattle were maintained in two different herd styles.In one style, cattle from various herds were placed together on the same pasture duringsummer. In the other, cattle were kept in their own herds throughout the year. Morethan one-half (52.17) of the former cattle was positive for BLV antibodies, but only 8.1%of the latter cattle was positive. Reactors increased gradually in number with the advancein age. Eighty-eight percent of the animals which had shown lymphocytosis in the hematological test was positive for BLV antibodies, whereas 38.3% of the animals free fromlymphocytosis was also positive. These results indicated that there was a relationshipbetween BLV infection and the incidence of lymphocytosis.View full abstractDownload PDF (574K) -

JOURNAL FREE ACCESSWhen inoculated by various routes with approximately 10 (or 10") Brucellacanis organisms, all adult dogs became infected. When dogs were inoculated with approximately 10 organisms by different routes, the positive rate of infection by the route ofinoculation was as follows: 2/2 (No. infected/No. inoculated) (intravenous), 2/2 (sub-cutaneous), 2/4 (conjunctival), 074 (oral) and 073 (intravaginal). Five male dogs were in-oculated orally with 3.2Xl0 B. canis organisms and examined weekly for urine. Theorganisms were first detected in their urine a few weeks after the onset of bacteremia.Then a high concentration of these organisms was usually excreted continuously. Five4-week-old puppies born from a B. canis-free bitch were housed together with these in-fected males in an isolated facility for 18 weeks. One of them became infected. The trans-mission of brucellosis to the puppy seemed to have been caused by a contact with B. canis-contaminated urine.View full abstractDownload PDF (858K) -

JOURNAL FREE ACCESSVarious biochemical aspects of milk fever in cows were investigated. Affectedcows had significantly increased plasma levels of cortisol, free fatty acids (FFA), glucoseand Mg, and significantly lowered plasma levels of Ca and K, as compared with normalpostpartum cows. There were significant positive correlations between cortisol-FFA andcortisol-glucose and significant negative correlations between Ca-cortisol, Ca-glucose andCa-FFA in cows with milk fever. None of these correlations were significant in controlcows.View full abstractDownload PDF (621K) -

JOURNAL FREE ACCESSThe serovar-specific main (TM) antigen of Leptospira interrogans serovarhebdomadis (a variant which can grow in a modified Shenbergs synthetic medium) (hebdomadis variant) inhibited 507 agglutination of this strain and the reference strain ofhebdomadis with each homologous antiserum, but did not inhibit agglutination of anyother serovars belonging to Hebdomadis serogroup and 13 serovars of 8 other serogroups.The TM antigen of kremastos Kyoto did not inhibit agglutination of the other serovarsof llebdomadis serogroup, except that it inhibited only slightly the agglutination ofhebdomadis variant and jaies. These results and the results of the additional experimentsusing the TM antigens of icterohaernorrhagiae, copenhageni Shibaura and pomona, indi-cated that the inhibition of leptospiral agglutination by the homologous TM antigen wasserovar-specific.View full abstractDownload PDF (652K) -

JOURNAL FREE ACCESSForty-five bovine Ureaplasma strains were examined serologically by thegrowth inhibition and metabolism inhibition tests. They were found to be of considerableheterogeneity, and divided into three distinguishable serological groups. These groups, I, II and III, were composed of 24, 20 and one strains, respectively. Although no antigenicalcross-reaction was shown among the three groups by the growth inhibition test, a con-siderable amount of cross-reaction was recognized between groups I and II by the meta-bolism inhibition test. The strain of group III was distinct from any strain of the othergroups. Based on the results obtained, 7 strains were selected as the representatives of allthe strains studied. Twenty-six new isolates were further examined with antisera againstthe representative strains, and serotyped readily. Therefore, it seemed reasonable for the7 strains to have been selected as the representative serotypes of the bovine ureaplasmas.No serological relationship was shown between any bovine strain and any one of the 8human serotypes of Ureaplasma urealyticum.View full abstractDownload PDF (900K) -

JOURNAL FREE ACCESSCultures for ureaplasmas were made from various sites of 38 apparentlyhealthy and 5 dead dogs. Ureaplasmas were isolated from 27 (62.8%) of 43 oral cavities, 20 (46.5%) of 43 nasal cavities, 13 (59.1%) of 22 prepuces, 8 (38.1%) of 21 vaginas and 1(20%) of 5 tracheas, but not from eyes, recta or a lung examined. Thirty-six strains clonedfrom these cultures were divided into at least four distinguishable serological groups, A, B, C and D, by the growth inhibition and metabolism inhibition tests. Serogroups A, B, Cand D contained 6, 9, 8 and 13 strains, respectively. Groups A and B were composed ofstrains from various anatomical sites of dogs, whereas groups C and D consist of those mostfrequently isolated from the nasal cavity and urogenital tract, respectively. In addition, two serologically distinct strains were isolated simultaneously from a single specimen ofeach oral and nasal cavity. The canine unreaplasmas had no serological relation withhuman, bovine, simian or avian ureaplasmas.View full abstractDownload PDF (730K) -

JOURNAL FREE ACCESSElectroretinograms (ERGs) of normally pigmented and albino quail wererecorded under white flash light stimulation. In ERGs taken during first 3 days afterhatching at a flash intensity of 10 joule (J), the c-wave was found only in the albino, whilein the older birds it was found in ERGs of both phenotypes. The c-wave of the chick wasmuch faster in the time course than that of the adult. In the albino chick (day-5), whenthe flash intensities were increased from 1 to 10 J, there was a mark.ed decrease in theb-wave which was always associated with an increase in the c-wave. In some albino adultquail, low intensity of flash light (0.5 -1.0J) could bring about distinctive slow positivepotential (c-wave) and oscillatory potential (wavelets), while in the pigmented adult quail, higher intensity of flash light (10-40 J) was required to elicit comparable responses. Thea- and b-waves of albino were larger in amplitude than those of pigmented quail at anygiven flash intensity. These results indicate that the sensitivity of the mixed retina of thequail to a light stimulus is enhanced by the albinism.View full abstractDownload PDF (686K) -

JOURNAL FREE ACCESSAn attempt was made to follow the course of invasion into human and animalhairs by the dermatophyte, Trichophyton equinum, in vitro. One mZ of fungal suspension(1.1 -3.1X10 per m4 was inoculated on hairs. Under room temperature, the observationof hairs was done for 2 months. Simultaneously the reculture of hairs after treatment with0.2% HgCl. solution was carried out the confirmation of the invasion by T. equinum.From the result, guinea pig hairs were invaded by hyphae within 4 days after treatment;in cat and dog within [6 days, in rabbit within 4-9 days, in mouse and rats within 6 days.The hairs of horse and human, however, were slowly invaded after 9 days or so. As tothe form of hairs and T. equinum, the spores (microconidia) on hairs showed variety formdepending on the species of human and animals. The shape of them was globose, sub-globose, ovoid and subclavate. The hyphae were grown in hairs with broad type which indog showed 8 pm in width. The mode of keratinolysis was coaxial type in guinea pig hairsonly and rectangular type in the others.View full abstractDownload PDF (1151K) -
