A cross-sectional study was carried out to determine the prevalence and risk factors associated with gastrointestinal parasitism in dromedary camel calves in Isiolo County, Kenya. Data on farm-and calf-levels were collected through semi-structured questionnaires. The calves were examined, and a faecal sample was collected per rectum for laboratory analysis. The gastrointestinal parasite eggs and oocysts were estimated using the faecal floatation and McMaster methods in the laboratory. Descriptive analysis was used to summarize the variables, and multilevel mixed-effects logistic regression models were used to explore the association between helminth infection and the farm-and calf-level risk factors. A total of 308 calves in 25 households were recruited for this study. The mean number of calves per herd, age and weight were 38, 7.3 months and 169 kg, respectively, while the age at weaning was about 11 months. The overall prevalence of gastrointestinal parasitism was 42%, while that of nematodes and coccidia were 31 and 3.9%, respectively. In the first model, the factors that were significantly associated with nematode infections were total milk yield per day, calf age, and calf weight. In the second model, the factors that were significantly associated with Nematodirus species infection were the age of the calf, live body weight and average weaning age of the camel calves. The study concludes that gastrointestinal parasitism (especially nematodes) occurs in camel calves in Kenya. It is recommended that the pastoralists should be educated on the impact of gastrointestinal parasitic infections in camel calves, and the importance of strategic deworming.
这项横断面研究旨在确定肯尼亚伊西奥洛县单峰骆驼犊牛胃肠道寄生虫病的发病率和相关风险因素。通过半结构式问卷收集了农场和犊牛的数据。对小骆驼进行了检查,并从直肠采集粪便样本进行实验室分析。实验室采用粪便漂浮法和麦克马斯特法对胃肠道寄生虫卵和卵囊进行了估计。描述性分析用于总结变量,多层次混合效应逻辑回归模型用于探讨蠕虫感染与农场和犊牛风险因素之间的关联。本研究共招募了 25 个家庭的 308 头犊牛。每群犊牛的平均数量、年龄和体重分别为 38 头、7.3 个月和 169 千克,断奶年龄约为 11 个月。胃肠道寄生虫的总体感染率为 42%,线虫和球虫的感染率分别为 31% 和 3.9%。在第一个模型中,与线虫感染显著相关的因素是每天的总产奶量、犊牛年龄和犊牛体重。在第二个模型中,与线虫感染显著相关的因素是犊牛年龄、活体体重和骆驼犊牛的平均断奶年龄。研究得出结论,肯尼亚骆驼犊的胃肠道寄生虫(尤其是线虫)时有发生。建议对牧民进行教育,使其了解胃肠道寄生虫感染对骆驼犊的影响,以及战略性驱虫的重要性。

The ambient temperature has been found to affect the performance and immune response of broiler, hence the need for determination of immunoglobulin level routinely to evaluate their state of immunity call for concern. This study determines the effects of housing temperature and coconut water (CW) on serum immuglobulins of broiler chickens. A total of 600 Marshall broiler chickens were used, with 200 birds in different housing temperature: Cold (CHT, 18.3-22.1°C), Natural (NHT, 26.3-26.6°C), and Hot (HHT, 34.9-36.1). Each housing temperature was partitioned into five treatment groups: Ordinary water (T 1 ), 0.5 g of Vitamin C/L of water (T 2 ), 0.5% CW/L of water (T 3 ), 1% CW/L of water (T 4 ) and 1.5% CW/L of water (T 5 ), with four replicates and 10 birds per replicate. Immunoglobulin IgG, IgM and IgA were determined. Data collected were subjected to factorial arrangements with one-way Analysis of Variance. Housing temperature significantly (p<0.05) influenced immunoglobulin value for IgG and IgM. Birds under natural housing temperature had the highest IgG (1.62±0.07 mg/dl) compared to others under cold housing temperature (1.39±0.15 mg/dl) and hot housing temperature (0.38±0.07 mg/dl). The IgM level showed a negatively changing trend with birds under hot housing temperature having the highest value (1.95±0.07 mg/dl), followed by cold housing temperature (1.49±0.01 mg/dl), and natural housing temperature (1.06±0.11 mg/dl). Upon administration of coconut water and vitamin C to birds, there is a significant (p<0.05) influence on immunoglobulin values (IgG, IgM and IgA) across the three housing temperatures. It was therefore, concluded that change in ambient temperature can cause variation in immune response of birds and immune responses could be ensured by regulated administration of coconut water and vitamin C in broiler production.
研究发现,环境温度会影响肉鸡的生产性能和免疫反应,因此需要定期测定免疫球蛋白水平,以评估肉鸡的免疫状态。本研究确定了饲养温度和椰子汁(CW)对肉鸡血清免疫球蛋白的影响。本研究共使用了 600 只马歇尔肉鸡,其中 200 只鸡在不同的饲养温度下饲养:冷舍(CHT,18.3-22.1°C)、自然舍(NHT,26.3-26.6°C)和热舍(HHT,34.9-36.1°C)。每种饲养温度分为五个处理组:普通水(T 1)、0.5 克维生素 C/L 水(T 2)、0.5% CW/L 水(T 3)、1% CW/L 水(T 4)和 1.5% CW/L 水(T 5),共四个重复,每个重复 10 只鸡。测定免疫球蛋白 IgG、IgM 和 IgA。对收集的数据进行因子排列和单因子方差分析。饲养温度对免疫球蛋白 IgG 和 IgM 的值有明显影响(p<0.05)。在自然饲养温度下,鸟的 IgG 值最高(1.62±0.07 mg/dl),而在低温饲养温度下(1.39±0.15 mg/dl)和高温饲养温度下(0.38±0.07 mg/dl)的鸟的 IgG 值最低。IgM水平呈负相关变化趋势,热饲养温度下的鸟类IgM水平最高(1.95±0.07 mg/dl),其次是冷饲养温度下(1.49±0.01 mg/dl)和自然饲养温度下(1.06±0.11 mg/dl)。给家禽饮用椰子汁和维生素 C 后,对三种饲养温度下的免疫球蛋白值(IgG、IgM 和 IgA)有显著影响(p<0.05)。因此,得出的结论是,环境温度的变化会导致禽类免疫反应的变化,在肉鸡生产过程中,可通过规范饲喂椰子水和维生素 C 来确保免疫反应。

African tick-bite fever is a rickettsial illness that has recently emerged as a significant disease among international travelers. This tick-borne zoonosis is transmitted by Amblyomma ticks, which is endemic to sub-Saharan Africa and parts of the eastern Caribbean. Uganda is a major tourism destination with plenty of natural environments visited by tourists. In addition to tourists, the Ugandan population could also be at risk since the greater majority of Ugandans are rural based and dependent on agriculture.  The disease could be misdiagnosed at health care centers since it is not a priority. Key words: African tick-bite fever, Rickettsia africae, spotted fever group rickettsiosis, zoonosis, Uganda.
非洲蜱叮咬热是一种立克次体疾病,最近在国际旅行者中成为一种重要疾病。这种由蜱传播的人畜共患病是由扁蜱(Amblyomma ticks)传播的,它是撒哈拉以南非洲和东加勒比部分地区的地方病。乌干达是一个主要的旅游目的地,有很多游客参观的自然环境。除游客外,乌干达人口也可能面临危险,因为绝大多数乌干达人居住在农村,依赖农业。这种疾病可能在医疗中心被误诊,因为它不是优先考虑的问题。关键词:非洲蜱叮咬热,非洲立克次体,斑点热群立克次体病,人畜共患病,乌干达

Herbal remedies have a long history of use for tick control. Solanum incanum ripe fruits are locally used to manage ticks. In this study, the effect of S. incanum fruit extracts on egg hatchability, inhibition of oviposition and larval mortality of Rhipicephalus appendiculatus ticks was investigated. The reproductive efficiency of eggs laid by the ticks was determined. The highest number of eggs laid was recorded in the untreated control, whereas the lowest was in the control treated with amitraz. The number of eggs that were laid after treatment with the plant extract increased with increase in the extract concentration, that is, 20, 10 and 5% was 51.0262, 43.774 and 36.901%, respectively. The control treated with amitraz showed higher efficacy of 98.63556% whereas the untreated control had no effect on the ticks. S. incanum 5% showed higher efficacy of 33.49%, than 10 and 20%, which showed 19.405 and 7.833%, respectively. However, there was no significant differences in efficacies between the fruit extract concentrations. In the results obtained from the larval packet test (LPT), the control treated with amitraz was recorded with the highest mortality of 100% whereas the untreated control showed no significant larval mortality. There was high larval mortality recorded in all the three concentrations of S. incanum, of 100, 50 and 25 mg/ml with 97.969, 98.589 and 95.948%, respectively. Key words: Efficacy, Solanum incanum, Rhipicephalus appendiculatus.
草药在控制蜱虫方面有着悠久的历史。龙葵成熟的果实在当地被用来对付蜱虫。本研究研究了白荆果实提取物对尾尾棘头蜱卵孵化率、产卵抑制和幼虫死亡率的影响。测定了蜱卵的繁殖效率。产卵数以未处理组最高,而以阿米特拉兹处理组最低。植物提取物处理后产卵数随提取物浓度的增加而增加,分别为20%、10%和5%,分别为51.0262、43.774和36.901%。阿米特拉兹对蜱虫的防治效果为98.63556%,而未处理的蜱虫对蜱虫的防治效果不明显。5%白芷的有效率为33.49%,高于10%和20%,分别为19.405和7.833%。然而,果实提取物浓度之间的功效没有显著差异。幼虫包试验(LPT)结果显示,阿米特拉兹处理的对照组幼虫死亡率最高,为100%,而未处理的对照组幼虫死亡率不显著。在100、50和25 mg/ml浓度下,幼虫死亡率均较高,分别为97.969、98.589和95.948%。关键词:疗效;龙葵;尾头;

Mycobacterium avium subspecies paratuberculosis (Map) is the etiological agent of paratuberculosis, which is one of the chronic diseases that cause financial losses in livestock production. Map can be present in cheese and other dairy products, especially those made with unpasteurized milk. Contamination of the food supply chain exposes humans to the bacteria, making the disease an important zoonosis of public health significance and a one-health emergency. The purpose of the study was to determine the presence of Map in raw goat milk, natural rennet, and artisanal fresh cheese. A total of 18 milk samples were collected directly from the bulking tank, 23 from fresh cheese, and 10 from milk rennet from five municipalities in the State of San Luis Potosi, Mexico. Samples were analyzed through bacteriological culture and IS900 PCR-n. Statistical analysis was carried out in STATA® 7.0, analyzing frequencies and the Kappa test to determine the concordance index between bacteriological culture and IS900 PCR-n results. Map was isolated from four milk samples (n=4/18, 22%), one from cheese (n=1/23, 4.3%), while none were obtained from rennet samples. IS900 PCR-n detected 22 positive samples: 6/18 (33.3%) in milk, 8/10 (80%) in rennet and 8/23 (34.74%) in cheese. Concordance between IS900 PCR-n and bacteriological culture in milk samples was high (0.7273) but low in cheese samples (0.0707). Map was detected in milk and artisanal cheese, although it is noteworthy that Map genomic material was detected in 80% of rennet samples analyzed with PCR. Quality control of milk, rennet, and all the inputs used for making cheese is necessary. Key words:  Paratuberculosis, map, fresh milk, cheese, rennet, goats
禽分枝杆菌亚种副结核(Map)是副结核的病原,是造成畜牧生产经济损失的慢性病之一。Map可以存在于奶酪和其他乳制品中,特别是那些用未经巴氏消毒的牛奶制成的乳制品。食品供应链的污染使人类暴露于细菌,使该疾病成为具有公共卫生意义的重要人畜共患病和单一卫生紧急情况。本研究的目的是确定Map在生羊奶、天然凝乳酶和手工新鲜奶酪中的存在。在墨西哥圣路易斯波托西州的五个城市,直接从储罐中收集了18份牛奶样本,23份来自新鲜奶酪,10份来自牛奶凝乳酶。通过细菌培养和IS900 PCR-n对样品进行分析。在stata®g中进行统计分析;7.0,分析频率和Kappa检验,确定细菌培养与IS900 PCR-n结果的一致性指数。从4份牛奶样品(n=4/18, 22%)和1份奶酪样品(n=1/23, 4.3%)中分离到Map,而从凝乳样品中未分离到Map。IS900 PCR-n检测阳性22份,其中牛奶6/18(33.3%)、凝乳酶8/10(80%)、奶酪8/23(34.74%)。牛奶样品IS900 PCR-n与细菌培养的一致性较高(0.7273),奶酪样品IS900 PCR-n与细菌培养的一致性较低(0.0707)。在牛奶和手工奶酪中检测到Map,尽管值得注意的是,在80%的聚合酶链反应分析的凝乳酶样品中检测到Map基因组物质。对牛奶、凝乳酶和所有用于制作奶酪的原料进行质量控制是必要的。关键词:,副肺结核,地图,鲜牛奶,奶酪,凝乳酶,山羊

Giardia duodenalis is an emerging zoonotic protozoan parasite that is significantly affecting the health and welfare of dogs in Nairobi County, Kenya. There is limited data on canine giardiasis in Kenya. A cross-sectional study was conducted to determine the prevalence, risk factors and molecular identity of G. duodenalis infections in dogs in Nairobi County, Kenya. Four hundred fecal samples were collected from randomly selected dogs and subjected to Giardia SNAP test which is a rapid antigen ELISA test to determine the Giardia antigen in the faeces. Positive fecal samples were subjected to molecular analysis through PCR and thereafter sequencing to determine the circulating Giardia genotypes. A Spatial Bernoulli model in SaTScan was used to investigate clustering of Giardia infection in dogs within Nairobi County. A questionnaire was administered to the dog owners to capture data on risk factors for Giardia infection in dogs. Multivariate analysis was used to determine the association between the occurrence of infection and the predicted risk factors. The overall prevalence of Giardia infection in dogs in Nairobi County, Kenya in this study was 22.3%. The risk of infection was 0.99 times during wet season and 0.22 times in young dogs < 12 months.  Roaming/stray or dogs that were never housed in kennels had 3.04 times the chances of contracting the infection. Spatial analysis showed two clusters with a high risk of Giardia infection within Nairobi County. Zoonotic assemblages A and B and a mixed infection of both were also isolated in dogs in Nairobi County, Kenya. In conclusion, young and roaming or stray dogs have a higher risk of Giardia infection with the risk of infection being high during the wet season. Dogs within Nairobi County harbor zoonotic assemblages A and B which could pose a public health risk to humans. Key words: Dogs, Giardia duodenalis, prevalence, risk factors, zoonotic genotypes.
十二指肠贾第虫是一种新出现的人畜共患原虫寄生虫,严重影响肯尼亚内罗毕县狗的健康和福利。肯尼亚关于犬贾第虫病的数据有限。在肯尼亚内罗毕县进行了一项横断面研究,以确定犬中十二指肠梭菌感染的流行情况、危险因素和分子特征。随机抽取400只狗的粪便样本,进行贾第鞭毛虫SNAP试验,这是一种快速抗原ELISA试验,以确定粪便中的贾第鞭毛虫抗原。对阳性粪便样本进行PCR分子分析,然后进行测序,确定流行贾第鞭毛虫基因型。使用SaTScan中的空间伯努利模型调查内罗毕县犬中贾第鞭毛虫感染的聚集性。对狗主人进行问卷调查,以获取狗感染贾第鞭毛虫的危险因素数据。采用多变量分析确定感染发生与预测危险因素之间的关系。在本研究中,肯尼亚内罗毕县犬中贾第鞭毛虫感染的总体流行率为22.3%。湿季感染风险为0.99倍,幼犬感染风险为0.22倍;12个月只流浪/流浪或从未住在狗窝的狗感染感染的几率是3.04倍。空间分析显示内罗毕县有两个贾第鞭毛虫感染高风险聚集。在肯尼亚内罗毕县的狗中也分离出人畜共患病组合A和B以及两者的混合感染。总之,幼犬和流浪狗或流浪狗感染贾第鞭毛虫的风险较高,在雨季感染风险较高。内罗毕县的狗携带有人畜共患病毒A和B,可能对人类构成公共卫生风险。关键词:犬,十二指肠贾第鞭毛虫,流行,危险因素,人畜共患病基因型

The veterinary drug is vital for healthy and quality food-animal production. Their use in poultry production is basically for treatment, prophylaxis and growth promotion. However, cases of misuse of these drugs by the poultry farmers have been reported. This is further worsened by extra-label use and non-observance of withdrawal period, leading to deposition of drug residues in poultry products, thus posing a public health concern. This paper assessed the poultry farmers’ knowledge, attitude and practice of observing withdrawal period of veterinary drugs. Three hundred and eighty-five (385) questionnaires were administered and 380 (98.7%) response rate was recorded. Data were analyzed using Statistical Package for Social Sciences 23 and presented in frequency tables. Chi-square was used to determine the relationship between the variables. 57.1% of the poultry farmers in Zaria though well-educated had never checked withdrawal period while 53.2% of the farmers have ever sold their chicken/eggs while on medication. 67.5% out of the 42.9% of farmers that checked the withdrawal period on the packaging materials indicated 14 days as withdrawal period. There existed a strong relationship between the socio-demographic characteristics and other variables (p<0.05). The farmers managed the encountered poultry diseases using most common drugs; Doxygen® (43.2%) and Tylodox® (40%) for duration ranging from 3 to 7 days depending on disease severity and mortality rate. It is suggested that poultry farmers should follow information written on the packaging materials; strict legislation and extensive awareness on observing withdrawal period of drugs should be implemented by the government and relevant stakeholders. Key words: Knowledge, withdrawal period, veterinary drugs, poultry, Zaria.
兽药对健康、优质的食品动物生产至关重要。它们在家禽生产中的用途主要是治疗、预防和促进生长。然而,已有家禽养殖户滥用这些药物的报告。这种情况由于超出标签使用和不遵守停药期而进一步恶化,导致药物残留物沉积在家禽产品中,从而引起公共卫生问题。本文对家禽养殖户进行了评价;遵守兽药停药期的知识、态度与做法。共发放问卷385份,回复率380份(98.7%)。使用社会科学统计软件包23对数据进行分析,并以频率表的形式呈现。采用卡方法确定变量之间的关系。尽管受过良好教育,Zaria 57.1%的家禽养殖户从未检查过停药期,53.2%的养殖户曾在服药期间出售过鸡/鸡蛋。在42.9%的农户中,67.5%的农户在包装材料上标注了14天为撤回期。社会人口统计学特征与其他变量之间存在较强的相关性(p<0.05)。农民使用最常见的药物对遇到的家禽疾病进行管理;Doxygen®(43.2%)和Tylodox®(40%)根据疾病严重程度和死亡率,持续时间从3天到7天不等。建议家禽养殖户应遵循包装材料上的信息;政府和相关利益相关方应严格立法,提高遵守药品停药期的意识。关键词:知识;停药期;兽药;

A cross-sectional study was conducted from December 2019 to March 2020 to detect the major causes of carcass condemnation and to estimate the attributed financial loss in chickens slaughtered at a private poultry slaughterhouse in Bishoftu, Ethiopia. The study involves a postmortem (PM) inspection of 400 randomly selected chickens. From a total of 400 chickens subjected to PM examination, 77 (19.25%) of them had abnormalities. Of these, 35(8.75%) chickens were totally condemned, while 42 (10.5%) were partially rejected. The major causes of total carcass condemnation observed during this study were machine damage (4.25%), poor bleeding (2.5%), emaciation (1.25%), and septicemia (0.5%). While bruise (7.25), fracture of bone (2%), arthritis (1%) and machine damage (0.25%) were the major causes of partial condemnation, respectively. The high bruises occurrence in the slaughterhouse was due to poor handling of the poultry during transportation and hoisting. The annual financial loss incurred due to carcass condemnation to the slaughterhouse in the study period was estimated to be ETB 660,480 or USD 19,144.34. Improving the management of harvesting, transportation, and adjustment of the equipment used at slaughter can reduce the effect on the carcass and financial losses. This type of study especially, on poultry was not reported so far in Ethiopia therefore; this finding can be used as baseline information for further investigation and controlling of factors responsible for chicken meat condemnation in a poultry slaughterhouse. Key words: Carcass, condemnation, financial, losses, poultry, slaughterhouse.
2019年12月至2020年3月进行了一项横断面研究,以查明胴体谴责的主要原因,并估计埃塞俄比亚比绍夫图一家私营家禽屠宰场屠宰的鸡的经济损失。该研究包括对随机选择的400只鸡进行死后检查。在400只鸡的PM检查中,77只(19.25%)出现异常。其中,完全拒斥鸡35只(8.75%),部分拒斥鸡42只(10.5%)。在本研究中观察到的胴体总谴责的主要原因是机器损伤(4.25%),出血不良(2.5%),消瘦(1.25%)和败血症(0.5%)。而瘀伤(7.25%)、骨折(2%)、关节炎(1%)和机器损伤(0.25%)分别是部分谴责的主要原因。屠宰场的高瘀伤是由于家禽在运输和吊装过程中处理不当造成的。在研究期间,由于屠体报废给屠宰场造成的年度经济损失估计为660,480欧元或19,144.34美元。改进收获、运输管理和调整屠宰时使用的设备可以减少对胴体的影响和经济损失。因此,这种类型的研究,特别是对家禽的研究,到目前为止尚未在埃塞俄比亚报告;这一发现可作为基线信息,用于进一步调查和控制家禽屠宰场的鸡肉谴责因素。关键词:胴体,谴责,财务,损失,家禽,屠宰场。

Myiasis is the infestation of living tissues of human and animals with larvae of flies in the Order Diptera. This study determined the gross and histopathological lesions due to Cordylobia anthropophaga infestations of Dogs in Kitui County, Kenya. Four dogs identified and confirmed to have canine cutaneous myiasis (CCM) infestation were purchased for the study. All the study animals were clinically examined for skin lesions characteristic of CCM and euthanized for complete necropsy examination and histopathological sample collection. Tissue sections were collected from areas with lesions of CCM namely; skin, skeletal muscles and regional draining lymph nodes. They were preserved in 10% buffered formalin and were processed and analyzed using standard methods. Grossly, all dogs had poor body condition, patches of alopecia, emaciated and had the pathognomonic lesions for canine cutaneous myiasis (CCM) characterized by multifocal coalescent nodular lesions (harboring Cordylobia anthropophaga larvae) with 3 mm diameter central pore (furuncles) and erythematous base. Some had serous, hemorrhagic or purulent discharges from the furuncles that matted surrounding hairs. Lesions were distributed mainly on the ventral abdomen, axilla, flanks, legs, perineum and external reproductive organs. Examination of the skin revealed that the furuncular lesions extended throughout the skin thickness from epidermis to the sub-cutis and underlying pale skeletal muscles. There was regional lymphadenopathy in affected body regions. Histopathology confirmed the main lesions in all the dogs were parasitic granulomas, congested blood vessels in the surrounding tissues and eosinophilic lymphadenitis. The granulomas were located in the skin and the underlying skeletal muscles. The lesions were characterized by centrally located parasite, surrounded by connective tissue and heavy infiltration with inflammatory cells predominantly eosinophils. Draining lymph nodes had eosinophilic lymphadenitis. The reported pathological lesions resulted in unthriftiness, alopecia, lethargy and anorexia due to pain and stress resulting to emaciation and possible death. There is need to eradicate the etiological agent as it affects the wellbeing of dogs in the study area.
蝇蛆病是双翅目蝇的幼虫侵染人类和动物的活体组织。本研究确定了肯尼亚基图伊县犬嗜人虫草菌感染引起的大体和组织病理学病变。为研究购买了4只鉴定并确认有犬皮蝇病(CCM)感染的狗。所有实验动物临床检查CCM特征的皮肤病变,并实施安乐死,进行完整的尸检和组织病理学样本采集。从CCM病变区域采集组织切片,即;皮肤,骨骼肌和局部引流淋巴结。它们保存在10%的缓冲福尔马林中,并使用标准方法进行处理和分析。总的来说,所有的狗身体状况都很差,斑秃,瘦弱,并且有犬皮蝇病(CCM)的典型病变,其特征是多灶聚结性结节病变(含嗜人虫草幼虫),中心孔直径为3mm(疖),基部红斑。有些人有浆液、出血性或脓性分泌物,从缠结在毛发周围的疖中流出。病变主要分布于腹侧、腋窝、两侧、腿部、会阴及外生殖器官。皮肤检查显示,疣状病变从表皮延伸到皮肤下和下面苍白的骨骼肌。受累部位有局部淋巴结病变。组织病理学证实所有犬的主要病变为寄生肉芽肿、周围组织血管充血和嗜酸性淋巴炎。肉芽肿位于皮肤和下面的骨骼肌。病变的特征是位于中心的寄生虫,被结缔组织包围,炎症细胞大量浸润,主要是嗜酸性粒细胞。引流淋巴结有嗜酸性淋巴结炎。报告的病理病变导致节俭,脱发,嗜睡和厌食,由于疼痛和压力导致消瘦和可能的死亡。有必要根除病原体,因为它会影响研究区域狗的健康。
