近年来宠物经济快速发展,新型宠物食品层出不穷,而对于宠物食品快速发展的原因鲜有从人类需求层面进行分析.本文从犬猫起源的角度出发,针对犬猫与人类的关系及宠物食品的发展进行讨论,发现犬猫在起源上就具有陪伴属性,是宠物食品创造了宠物本身,宠物食品的快速发展恰恰体现的是"人民对美好生活的需要",于是从人类本身需求的层面上对宠物... 相似文献

Anaplasma marginale is a tick-borne pathogen of cattle that causes the disease bovine anaplasmosis worldwide. Major surface proteins (MSPs) are involved in host-pathogen and tick-pathogen interactions and have been used as markers for the genetic characterization of A. marginale strains. A. marginale genotypes are highly variable in endemic areas worldwide. The genetic composition of A. marginale strains during anaplasmosis outbreaks has been characterized in one study only which reported a single msp1alpha genotype in infected cattle. However, more information is required to characterize whether a single genotype is responsible for an anaplasmosis outbreak or whether multiple genotypes can cause disease in na?ve cattle within a single herd in endemic areas. The aim of this study was to characterize the genetic diversity of A. marginale strains from an outbreak of bovine anaplasmosis in the State of Tamaulipas, Mexico. A. marginale genotypes were characterized at the molecular level using msp4 and msp1alpha gene sequences. The results revealed that several A. marginale genotypes are present in cattle during acute anaplasmosis outbreaks, thus suggesting that mechanical transmission or stochastic biological transmission through equally efficient independent transmission events may explain A. marginale genotype frequency in a cattle herd during acute bovine anaplasmosis outbreaks in endemic areas. The results reported herein corroborated the genetic heterogeneity of A. marginale strains in endemic regions worldwide. The development and implementation of anaplasmosis control measures is dependent upon understanding the epidemiology of A. marginale in endemic regions, including the characterization of the genetic diversity of strains that produce outbreaks of bovine anaplasmosis. 相似文献

Fatal congenital anaplasmosis associated with bovine viral diarrhoea virus (BVDV) infection in a crossbred calf 总被引：1，自引：0，他引：1
Pypers AR Holm DE Williams JH 《Journal of the South African Veterinary Association》2011,82(3):179-182
Clinical disease resulting from the vertical transmission of Anaplasma marginale has only been reported on 5 occasions despite studies demonstrating successful in utero transmission. During the reported experimental induction of congenital anaplasmosis in calves, the outcome was variable but mostly led to inapparent or mild infection. There are previous case reports of fatal congenital anaplasmosis following natural infection. The clinical findings in a 2-day-old calf presented to the Onderstepoort Veterinary Academic Hospital with clinical signs of congenital anaplasmosis, which was unresponsive to treatment, are described. Subsequent post mortem diagnostic tests revealed that this calf was co-infected with bovine viral diarrhoea virus (BVDV). It is postulated that immunosuppression resulting from BVDV infection predisposed to severe, fatal anaplasmosis in this calf. 相似文献

The sheep ked Melophagus ovinus was evaluated as a possible vector of Anaplasma ovis. In 4 tests, 45 to 293 keds were transferred from sheep with acute anaplasmosis, low level parasitemia, or carrier state of anaplasmosis to individual splenectomized ewes. Keds were confined in stockinette cages attached to the dorsal midline of the recipient hosts for 10 days. Throughout the 90-day observation periods after the keds were transferred, no clinical, serologic, or hematologic evidence of anaplasmosis was detected in any of the ked-recipient ewes. Results indicate that sheep keds probably are not mechanical or biological vectors of the ovine anaplasmosis organism. 相似文献

西藏西北部分地区山羊无浆体病的流行病学调查 《畜牧与饲料科学》2016,37(6):132-132
为掌握西藏西北羌塘草原部分山羊养殖大县山羊无浆体病流行状况,利用快速凝集试验对日土、革吉、措勤和尼玛4县山羊480份血液进行山羊无浆体病检测。结果表明,山羊无浆体病在日土、革吉、措勤和尼玛4县公路沿线的山羊中普遍流行,山羊无浆体病平均阳性率为10.42%。其中1岁以内仔山羊无浆体病阳性率在7.50%~12.50%,以措勤县为低（7.50%）,革吉和尼玛2县为高（12.50%）;1~2岁山羊无浆体病阳性率4县均为10.00%;2岁以上山羊无浆体病阳性率在10.00%~12.50%,以日土县为高（12.50%）。山羊无浆体病存在于西北羌塘草原日土、革吉、措勤和尼玛4县山羊群体中,应重视该病的防治。 相似文献

Spatial analysis was used in combination with more traditional epidemiologic methods to study patterns of anaplasmosis in a transitional area between anaplasmosis endemic and non-endemic regions. Data were collected using a mail survey from 179 veterinarians with practice areas including 100/102 Illinois counties. The pattern of anaplasmosis reported by practitioners did not follow the general distribution of cattle and was clustered, with two major endemic foci. Endemic counties (22/100 counties) were bordered by areas of intermediate endemicity (36/100 counties) with only sporadic cases occurring in the remainder of the state (42/100 counties). Clinical disease occurred mainly in late summer and early fall with a small number of new herds diagnosed during the winter. Illinois practitioners most commonly identified horseflies and other biting flies as the vectors of anaplasmosis but also believed mosquitos, ticks and iatrogenic means could account for transmission in their practice areas. Ries were most often reported in summer while iatrogenic transmission was more commonly reported with winter outbreaks. Vaccination and low level antibiotics were used in endemic areas but only by a small proportion of respondents (12%). Veterinarians in endemic and marginal areas also used antibiotics to clear infection from herds more often than did those experiencing sporadic cases in non-endemic areas. Many practitioners expressed uncertainty about the actual extent of the problem in their areas. Wooded land area was used as a proxy to test for co-distribution of general vector habitat with anaplasmosis. Significantly more anaplasmosis was found in the more wooded parts of the state (based on the Kappa statistic). Respondents from western Illinois reported carrier cattle to be the source of infection for most new outbreaks while white-tailed deer were considered to be as important a reservoir as cattle in southern Illinois. Spatial analysis did not support an important role for white-tailed deer. 相似文献

Canine babesiosis is an important global tick-borne infectious disease of domestic dogs and wild canids. B. gibsoni and B. vogeli are the most widespread species mainly endemic in dog population in southern and eastern regions of China. In this study, 272 blood samples were collected from pet dogs in five districts of Shenzhen, China. Babesia DNA was detected in 30 samples with an overall prevalence of 11.0 % in pet dogs in Shenzhen. The difference in the positive rate between female and male pet dogs, among different breed, and among the five sampling sites was not significant, while the age and health status of pet dogs significantly influence the positive rate of Babesia spp. infection. Sequencing results showed the presence of only B. vogeli in all of the samples tested. Sequence comparison and phylogenetic analysis revealed that all 30 strains of Babesia identified in this study shared the highest identity with B. vogeli. In sum, all results of this study showed a considerable high infection rate of Babesia spp. in pet dogs, and B. vogeli was the only Babesia species infecting pet dogs in Shenzhen city. Such information is necessary to help to elucidate the epidemiology of canine babesiosis in Shenzhen, and it is necessary to actively monitor this disease in pet dogs. 相似文献

On the basis of questionnaire surveys and personal interviews with veterinarians, ranchers, and livestock farm advisors, the seriousness of anaplasmosis in California was determined. In 1976, the economic loss due to anaplasmosis in the study sample of beef cattle was $2,203,150. When inferences were made from the sample population to include the whole population of beef cattle, this loss was estimated to be $5,244,319. These values were in contrast to a farm advisors' estimate of $11 million loss due to anaplasmosis, which was included in a total estimated loss of $300 million due to all livestock diseases of economic importance in California. It appeared that anaplasmosis, although having a substantial economic impact in California, is not as economically devastating as it was once thought to be. It was concluded that private programs currently in use (vaccination and treatment) are sufficient to control anaplasmosis. 相似文献

The keeping of fish as pets is a hobby that has experienced increasing popularity over the past decade. The hobby has also become more sophisticated in recent years and a growing number of veterinarians are gaining clinical experience and knowledge in the area of pet fish medicine. The opportunity to apply this knowledge to a pet fish problem can be a rewarding experience. This article focuses on managing acute and critical problems of pet fish at times when veterinary intervention is required within an emergency time frame. 相似文献
