附红细胞体病(Eperythrozoonosis)是由专性血液寄生生物——附红细胞体(Eperythrozoon)引起的一种以贫血、黄疽、发热为主要临床特征的疾病。我国自晋希民(1981)首先报道家兔附红细胞体病以来,牛、羊的附红细胞体病也相继见报.近年来猪的附红细胞体在我国少数地区也已发现.笔者在国内首次发现犬附红细胞体病后(已报道),1991年在上海地区又首次发现仔猪罹患本病.病猪死亡率最高可达50％,耐过的猪则生长发育受阻而成为僵猪,对养猪业危害较大. 相似文献

The defect causing malignant hyperthermia has been proposed to involve cardiac as well as skeletal muscle. We tested the hypothesis that histomorphometric parameters for ventricular wall from malignant hyperthermia-susceptible swine and dogs were abnormal. Hearts were obtained from: mature dogs, age- and weight-matched young swine (89 +/- 15 days, 30 +/- 3 kg); and market-weight swine (102 +/- 10 kg). Using light microscopy, estimates were made for muscle nuclear dimensions and the volume-fraction of nuclei, sarcoplasm, blood vessels, and interstitial space. Cardiac maturation in both MH and normal swine was accompanied by decreased myocyte volume-fraction due to decreased nuclear volume-fraction and increased interstitial space volume-fraction. Sarcoplasm and vasculature volume-fraction were unchanged after maturation. Nuclear volume-fraction was slightly greater (p less than 0.05) in the right ventricle than the left for malignant hyperthermia and normal swine. Myocyte nuclear dimensions were generally similar among animals. Dogs and the oldest group of swine were not significantly different. Myocytes of all swine contained multiple nuclei, closely spaced in rows of 2 to 12. In contrast, most myocytes of mature dogs apparently contained one or two nuclei. Histomorphometric values were not significantly different between normal and malignant hyperthermia young swine and dogs. However, within the market-weight swine, volume-fraction for malignant hyperthermia myocytes and myocyte nuclei was decreased and interstitial space was increased compared to normal.(ABSTRACT TRUNCATED AT 250 WORDS) 相似文献

Sarcocystis infections in Georgia swine 总被引：1，自引：0，他引：1

Tissues from 168 mature sows obtained at slaughter in northern and southern Georgia were examined for infection with Sarcocystis spp. Digestion techniques revealed zoites in 28 (16.5%) sows. Infected meat was fed to laboratory-reared dogs, cats, raccoons (Procyon lotor), and opossums (Didelphis marsupialis). Dogs and raccoons shed sporocysts (8.3 mum X 11.2 mum) 12 to 14 days after infection. Cats and opossums were refractory to infection. Sarcocystis-free pigs were infected with 50,000 sporocysts of swine-dog origin. Tissues from laboratory-infected swine were fed to dogs and raccoons. Both species shed sporocysts 14 days later. This is the 1st time in which a definitive host has been demonstrated for species of Sarcocystis occurring in North American swine. The raccoon constitutes a new definitive host for S suicanis Erber 1977. In contrast to previously reported low prevalences of Sarcocystis infections in swine, the relatively high prevalence reported here indicates that S suicanis may be of importance to swine producers in Georgia. 相似文献

The presence of antibodies against Encephalitozoon cuniculi (E. cuniculi) and Encephalitozoon intestinalis (E. intestinalis) was examined in 215 samples from humans and in 488 samples from five different species of domestic and companion animals in Slovakia. The 215 human samples and samples from 90 swine, 123 non-infected cattle (cattle), 24 cattle infected with bovine leukosis virus (BLV-positive cattle), 140 sheep and 111 dogs were examined by the enzyme-linked immunosorbent assay (ELISA). Samples with serum titres 1:200 or higher were considered as positive. Specific anti-E. cuniculi antibodies were found in humans (0.9%), swine (52%), cattle (2%), sheep (9%) and dogs (15%) except for the BLV-positive cattle at the titre of 1:200. The titre of 1:400 was detected only in humans (0.5%). The presence of specific anti-E. intestinalis antibodies at the titre of 1:200 was confirmed in humans (6%), swine (51%), cattle (11%), BLV-positive cattle (13%) and dogs (6%) but not in sheep. The anti-E. intestinalis antibodies reached the 1:400 in humans (1%), swine (4%) and BLV-positive cattle (17%). The presence of specific anti-E. intestinalis antibodies at the titre of 1:600 was observed only in one swine (1%). Significant differences were observed in animals at titres 1:200 and 1:400 (chi-squared test: p < 0.0001) for both pathogens and in humans only for E. cuniculi at the titre of 1:400 (chi-squared test: p < 0.0075). 相似文献

A macromethod and a semimicromethod were developed to measure erythrocyte acetylcholinesterase activity in cattle, sheep, goats, horses, dogs, and swine, and to measure plasma cholinesterase activity in horses, dogs, and swine. Comparison of the 2 methods with erythrocytes of sheep, cattle, goats, and horses indicated both methods gave similar results. They can be done in a shorter time and are more sensitive than Michel's method. Normal deltapH values per minutes, with standard deviations for blood cholinesterase activity of animals of different ages, sexes, breeds, and species, were: 0.76 +/- 0.12/30; 0.65 +/- 0.10/15; 0.69 +/- 0.19/45; 0.78 +/- 0.11/45; 0.63 +/- 0.11/45; and 0.71 +/- 0.06/25 for sheep, cattle, goats, horses, dogs, and swine erythrocyte acetylcholinesterase, respectively; and 0.66 +/- 0.18/20; 0.67 +/- 0.20/30, and 0.46 +/- 0.05/60 for horses, dogs, and swine plasma cholinesterase, respectively. It was shown that either the chloride or the iodide salt of acetylcholine can be used as the enzyme substrate. tin blood samples stored at 5 C for 24 hours, there was no significant change of the enzymatic activity. 相似文献

Prevalence of Toxoplasma gondii infection in man and animals in Guangdong, Peoples Republic of China
Tissue and serum samples from animals and man in Guangdong Province of the Peoples Republic of China were examined for Toxoplasma gondii infection. Tissues from 519 swine, 576 rodents, 84 people, one cat and two dogs were bioassayed in mice. T. gondii was isolated from 13 pools of swine tissues, but not from any other hosts. Serum samples from animals and man were examined at 1:64 dilution in the indirect hemagglutination test. Antibodies to T. gondii were found in 10.4% of 816 pigs, 0.9% of 955 rodents, 0.7% of 3085 people, 4.4% of 90 cattle, 8.3% of 12 rabbits and 2.1% of 47 cats. None were found in 83 buffaloes. 相似文献

Aujeszky's disease (AD), caused by Suid herpesvirus type 1 (SuHV-1), is an economically important disease in domestic swine. Thus, rigorous control programmes have been implemented and consecutively AD in domestic swine was successfully eradicated in many countries, including Austria. However, SuHV-1 continues to thrive in wild boar populations, as indicated by high seroprevalences in a number of European countries and by occasional cases of AD in hunting dogs. For the first time, SuHV-1 was detected in Austrian wild boar and a molecular characterization of SuHV-1 isolated from wild boar and hunting dogs was performed. Results of preliminary serological analyses suggest a regional SuHV-1 seroprevalence of over 30% in free-living and almost 70% in fenced wild boar from Eastern Austria. Molecular typing of Austrian SuHV-1 isolates of wild boar origin revealed the presence of two genetically distinct variants of SuHV-1, both capable of infecting dogs that have been exposed to infected wild boar during hunting. 相似文献
