1. The different methods of transmission of caprine pleutopneumonia have been investigated with the seed materials derived from the sporadic cases from Sinkiang, Shansi and Shantung Provinces. The results were briefly summaried as follows: (1) By subcutaneous inoculation, only local swelling and elevation of body temperature were found in a small number of goats, no pneumonic changes were seen from autopsy. (2) By intramuscular inoculation, the tested goats showed massive edema and necrosis at the site of inoculation and the surrounding area of the muscles, and nopulmonary lessions have been seen from autopsy. (3) By intravenous injection, one of the two goats was infected and hepatizafion of the lungs was observed. (4) By direct contact, the latent period is usually over 20 days. Both adult and kids might be infected. (5) By intrathoracic inoculation, the morbidity is approximately 72%. The latent period is uncertain. (6) By inhalation of atomized material through nostrils, the goat usually showed symptom 5—18 days later. (7) By intratracheal injection, the morbidity is about 95%, and the incubation period is 3—7 days. When the goats were injected in a standing position, the hepatized areas were usually seen on the right lung; when injected first in a recumbent position and then in standing position, the hepatized areas were usually seen on both sides of the lungs. 2. The virulent lung tissue of goat infected with caprine pleuropneumonia is non-patho-genic to sheep, rabbit and guinea pigs. 3. The infected lung tissue retained its virulence for 20 days in room temperature (16℃) and for 24 days in cold stroage (2℃) in 50% glycerin saline. 4. The frozen-dried lung tissue kept at 2—8℃ retained its virulence for 49 months. 5. The M. I. D. of fresh lung tissue for goat through intratracheal injection is about 0.000004 gin., while the frozen-dried lung tissue is about 0.004 gm. in equivalent for fresh lung tissue.

1.曾以山傳肺組織乳劑液或胸水,作對山羊之各種途徑感染試驗,其結果如下: (1)皮下注射法:僅使少數羊呈現體温及局部腫脹反應,但不引起山傳特具的肺臟病理變化。 (2)肌肉注射法:可引起局部及隣近的筋肉腫脹發炎,呈濕性壞死,重者陷於死亡,但肺臟無變化。 (3)靜脈注射法:可發生疾病並引起肺臟肝變。 (4)人工接觸法:在接觸20多天後,大多數羊均可發病,雖小羔亦難倖免。 (5)胸內注射法:發病率為了27%,潛伏期長短很不一致,肺的病變多限於局部。 (6)噴霧戚染法:有一部分羊經過噴霧感染後5—18天發病,並引起肺臟肝變。 (7)氣管注射法:發病率高達95%以上,潛伏期大多數為3—7天,用站立姿勢注射法,病變多在右肺葉,如採用站立仰臥姿勢兼用注射法,則病變遍於左右兩葉。 2.山傅的強毒肺組織液,不能使緬羊、家免及海猪等試驗動物致病。 3.新鮮肺組織在50%甘油鹽水中,置室温(16℃)20天,冰箱(2℃)124天,仍有致病力,如再延長時間,則失去致病力。但病原組織凍乾後,置普通冰箱保存49個月又13天,仍有致病力;2年以後,其發病毒價約減低10倍。新鮮病原組織小至0.000004克仍可致病。凍乾後毒力約減低1000倍...

Passive hemagglutinations(PH)were carried out on chicken serum samples with the NDV- sensitized tanned erythrocytes.When the highest dilution on which the strong agglutination occured was taken as the reading endpoint,the hemagglutinating titres of the four immune sera against NDV ranged from 1:40 to 1:640,while the other two normal control sera in 1:20 dilution gave negative results.Moreover,the titres of the PH corresponded in general the levels of the hemagglutination-inhibition(HI)titres of the same samples,but...

Passive hemagglutinations(PH)were carried out on chicken serum samples with the NDV- sensitized tanned erythrocytes.When the highest dilution on which the strong agglutination occured was taken as the reading endpoint,the hemagglutinating titres of the four immune sera against NDV ranged from 1:40 to 1:640,while the other two normal control sera in 1:20 dilution gave negative results.Moreover,the titres of the PH corresponded in general the levels of the hemagglutination-inhibition(HI)titres of the same samples,but the identity of the PH antibody and the HI antibody had not been determined. Suitable concentration of the viral antigen,removal of non-specific agglutinins from the serum samples and incubation for 15 min.at 37℃ for absorbing the viral antigen onto tanned erythrocytes were considered to be important factors necessary for the satisfactory perform- ance of the PH reaction. The possibility of the application of the PH test on other animal viruses and virus dis- eases was suggested.

本文报导了试用同接血凝试验检查新城鸡瘟抗体的具体方法及其结果。如以“++++”号强凝集作为判定格点,则正常鸡血清的滴度不到20~×,而免疫鸡血清分别呈现40~×、80~×、320~×、640~×等滴度,而且大致与各该血清的血凝抑止价相平行。待检血清中非特异性血球凝集性物质的除去以及应用一定浓度的病毒抗原,是取得成功结果的重要条件。

1. Temperature adjustment during incubation (Early stage 38.5℃, Midestage 38.0℃, Late stage 37.0℃) showed favorable effect on rate of embryonic development and intensity of nutrient metabolism. The effect of thermo-rise during the early stage was more striking 24 hours after setling of eggs; the experiment group surpassed the controls in rate of development by about one full day, judging from exterior appearance. From the 25th day onward, exterior difference between groups became less manifest, although...

1. Temperature adjustment during incubation (Early stage 38.5℃, Midestage 38.0℃, Late stage 37.0℃) showed favorable effect on rate of embryonic development and intensity of nutrient metabolism. The effect of thermo-rise during the early stage was more striking 24 hours after setling of eggs; the experiment group surpassed the controls in rate of development by about one full day, judging from exterior appearance. From the 25th day onward, exterior difference between groups became less manifest, although the experimental group pipped the shell earlier with greater strength, emerged early. The newly hatched ducklings were stronger with longer and fuller down, their average initial weight was heavier (47.76 gms as against 46.72 gms for the controls). As a consequence, hatchability was raised by 13.3% (Experimental, 75%, Control, 61.7%). 2. Growth curves of experimental group in length and weight of the embryo and its principal organs such as eye, heart, stomach, intestines, liver, lung, etc, fluctuated above those of the controls, except the heart, during the 25—27th day period only the former fell below the control group, slightly. 3. Manifestations indicating intensive metabolic rate were also in favor of the experimental group. For instance, decreases in egg weight were at faster rate than the control group. Descrepandies between the two groups were especially obvious in the utilization of egg white and egg yolk; egg white of the experimental group was completely utilized from the end of the 20th to the beginning of the 21st day, whereas it was delayed until the end of the 22nd and the beginning of the 23rd day in the controls, As the time of hatching the former had only 4.16 gms. of egg yolk left, while 6.23 gms was still left for the latter. Differences between the number of red blood cells and haemoglobin content were also apparent. 4. Roentgenographic measurements of ossified region taken from the diaphyses of the Humerus and Tibio-fibula likewise proved that the experimental group developed at a faster rate. 5. Sex differentiation was manifest at the 8th day for the experimental group as against the 9th day for the control group.

1.变溫条件(早期38.5℃,中期38.0℃,晚期37.0℃)可以改善胚胎发育的速度和胚体內某些指标变化的影响物质代謝的强度。初期升溫的效果在孵化开始的24小时以后較为明显。試驗組与对照組相比,发育速度一直領先,从外形来看,两組相差1昼夜。而到25昼夜以后,两組外形差別不大,但試驗組啄壳时間早,啄壳强而有力,出雛时間早,初生鴨雛健壮,絨羽长而丰滿,平均体重大(試驗組为47.76克,对照組为46.72克),从而提高了孵化率13.3%(試驗組75%,对照組61.7%) 2.胚胎及其主要器官,如眼、脑、心、胃、腸、肝、肺等长度和重量增长曲綫,試驗組的曲綫一直波动于对照組曲綫的上面,仅在25—27昼夜試驗組略有下降,其中心脏的情况,稍有例外。 3.一些能够說明物质代謝强度的指标,試驗組也一直領先。例如,卵重失重,壳重减重試驗組均快于对照組。特別是卵白、卵黃的利用方面,两組相差更为明显。試驗組在20昼夜末21昼夜初,卵白已被用尽,而对照組却延迟到22昼夜末23昼夜初。到出壳为止試驗組卵黄仅余4.16克,而对照組却还有6.23克。紅血球和血紅蛋白含量,两組差別也很明显。 4.X射綫直接摄影測量肱骨和小腿骨的骨干骨化区,也...
