A cross-sectional was performed in Nyala, South Darfur State, Sudan, over the time from November to December 2016, to determine the prevalence of bovine babesiosis and the potential risk factors associated with the infection. A total of 300 blood samples were randomly collected from three different areas, slaughterhouse, animal fauna, and dairy farms. Data on the risk factors, such as area, breed, age, sex, body condition, and tick infestation were recorded using questionnaires. The overall prevalence was 59.3% (178/300) using the microscopic examination of Giemsa stained slides. A significant variation in the prevalence of bovine babesiosis was observed among the three areas, whereas dairy farms (74%) having a significantly higher (p = 0.001) prevalence than the other areas. A factor found to be significantly associated with the infection with Babesia was the breed of cattle (p = 0.000), where the prevalence was higher in the crossbreed cattle (74%) than local breed cattle (52%). Other risk factors, like body condition, sex, age, and tick infestation were not found to be significantly associated with bovine babesiosis. However, the highest prevalence rate was recorded in males (65.3%) than females (58.1%), in young animals (62.5%) than adult (58.6%), in animals with poor body condition (64.3%) than the other, and in the animal non-infested with ticks (60.5%) than animal infested with ticks (55.8%). The present study revealed that the number of cattle suffering from babesiosis in Nyala was great. Therefore, sampling during different seasons and using molecular diagnostic methods are recommended for accurate prevalence estimate.Keywords: Babesia, risk factors, cattle, Nyala, Sudan
在2016年11月至12月期间,在苏丹南达尔富尔州尼亚拉进行了横断面调查,以确定牛巴贝虫病的流行情况以及与感染相关的潜在危险因素。从屠宰场、动物群和奶牛场三个不同的区域随机抽取300份血液样本。采用问卷调查方式记录危险因素数据,如地区、品种、年龄、性别、身体状况和蜱虫侵扰情况。吉姆萨染色玻片镜检总患病率为59.3%(178/300)。三个地区的牛巴贝斯虫病患病率存在显著差异,而奶牛场(74%)的患病率明显高于其他地区(p = 0.001)。发现与巴贝斯虫感染显著相关的一个因素是牛的品种(p = 0.000),其中杂交牛的患病率(74%)高于当地品种牛(52%)。其他危险因素,如身体状况、性别、年龄和蜱虫感染未发现与牛巴贝虫病显著相关。其中,雄鼠患病率最高(65.3%),雌鼠患病率最高(58.1%),幼鼠患病率最高(62.5%),成鼠患病率最高(58.6%),体质较差的动物患病率最高(64.3%),未染蜱动物患病率最高(60.5%),染蜱动物患病率最高(55.8%)。研究结果表明,尼拉县巴贝斯虫病发病人数较多。因此,建议在不同季节取样并使用分子诊断方法来准确估计患病率。关键词:巴贝斯虫,危险因素,牛,尼亚拉,苏丹

The present study was carried out in order to evaluate analgesia, heart andrespiration rates and rectal temperature values after lumbosacral epidural injection of three doses (20, 40 and 80 Kg/kg) of detomidine in Small East African goats. Twelve clinically healthy, adult, goats of both sexes whose weight ranged from 13 to 22 (mean ± SD; 16.5 ± 2.6) kg were used. Six out of the twelve goats were randomly assigned separately to each treatment group and at least one-week interval was left between subsequent injections. Heart and respiration rates and rectal temperature values were determined at time 0(pre-injection) and at 5, 10, 15, 20, and 30 minutes, thereafter at 15 minutes intervals up to 180 minutes after injection. Analgesia was determined after cardio-pulmonary measurements in unrestrained animal before administration of analgesics and thereafter at 5, 10, 15, 30 60, 120 and 180 minutes. All three doses induced adequate analgesia of the flank and perineum within 5 minutes, and persisted for the entire 180 minutes of the observation period. No significant differences were found between the analgesic effects of the three tested doses of detomidine. All doses induced significant drop of the mean respiration rate (RR) within 5 to 10 minutes. The RR depression effect persisted for the entire 180 minutes of the observation period. Significant drop of the mean heart rate (HR) was observed only for the two lower doses of 20 and 40 Kg/kg and persisted for 120 and 90 minutes respectively. All three doses induced a considerable rise in rectal temperature (RT) values that was followed by a gradual fall to normal. It was concluded that a two to four fold increase in the dose of detomidine administered through the lumbosacralepidural space does not increase the level and duration of the flank and perineal analgesia in Small East African goats.

The genus Campylobacter includes many species, most of which are known to be human and animal pathogens causing gastrointestinal diseases. The drugs of choice for treatment of human infections caused by these organisms are known to be fluoroquinolones and macrolides. In the recent past, however, the organisms have been observed to display resistance to antimicrobial agents including the drugs of choice. The present study determined the occurrence of antimicrobial resistant thermophilic Campylobacter in the feces of purging and non-purging dogs of different age groups in Morogoro, Tanzania. Fecal samples were collected from 404 dogs and subjected to the Cape Town protocol for isolation of thermophilic Campylobacter . Obtained isolates were tested for resistance against ten antimicrobial agents. Out of 404 sampled dogs, 40 (9.90%) were infected with thermophilic Campylobacter . C. jejuni comprised 82.5% of the total number of isolates. There were no statistically significant differences in the proportions of positive samples for thermophilic Campylobacter between those collected from adults (9.39%, n=298) and young (11.32%, n=106), and also between those collected from male (11.32%, n=212) and female (8.33%, n=192) dogs. All the thermophilic Campylobacter isolates were resistant to nalidixic acid and cephalothin. The lowest frequency of resistance was observed for ciprofloxacin. Resistance to other antimicrobial agents ranged from 15.0% to 95.0%. Multi-drug resistance was observed in 32.5% of all isolates. The findings of this study indicate that dogs are potential sources of human infections with antimicrobial resistant thermophilic Campylobacter . Attempts to eliminate infections caused by Campylobacter should take dogs into consideration, also should consider use of drugs that are effective for treatment of humans against the disease in order to succeed in treatment of campylobacteriosis.

弯曲杆菌属包括许多种类,其中大多数是已知的人类和动物病原体,引起胃肠道疾病。治疗由这些生物体引起的人类感染的首选药物已知是氟喹诺酮类药物和大环内酯类药物。然而,在最近的过去,已经观察到这些生物体对抗菌剂(包括所选择的药物)表现出耐药性。本研究确定了坦桑尼亚莫罗戈罗不同年龄组的泻犬和非泻犬粪便中耐药嗜热弯曲杆菌的发生率。收集404只狗的粪便样本,并按照开普敦方案分离嗜热弯曲杆菌。对获得的分离株进行了对10种抗菌药物的耐药性测试。404只犬中有40只(9.90%)感染了嗜热弯曲杆菌。空肠梭菌占总分离株数的82.5%。成年犬(9.39%,n=298)与幼犬(11.32%,n=106)、公犬(11.32%,n=212)与母犬(8.33%,n=192)嗜热弯曲杆菌阳性检出率差异均无统计学意义。所有嗜热弯曲杆菌分离株均对萘啶酸和头孢类药物耐药。环丙沙星耐药频率最低。对其他抗微生物药物的耐药性为15.0%至95.0%。32.5%的分离株存在多重耐药。本研究结果表明,狗是人类感染耐药嗜热弯曲杆菌的潜在来源。试图消除由弯曲杆菌引起的感染应考虑到狗,也应考虑使用有效治疗人类对抗疾病的药物,以便成功治疗弯曲杆菌病。关键词:伴侣动物,坦桑尼亚,嗜热弯曲杆菌

A cross sectional study was carried out between June and August 2014 to establish the status of helminthosis and coccidiosis in nine purposefully selected small ruminant flocks in Mlandizi village in Melela ward, Mvomero district of Morogoro region, Tanzania. The study aimed at generating baseline information for vaccine trials against Haemonchosis in traditional flock in tropical areas. A total of 131 goats and 118 sheep that were screened for helminth eggs and coccidian oocysts using McMaster flotation techniques. In addition, copro-culture was carried out to obtain third stage larvae for parasite identification to the genus level based on morphological features shown in identification keys. Approximately, 54.2% and 52.7% of the goats (n=131) had helminth and coccidia infestations while, 67.8% and 49.2% of sheep were positive for the two parasite types, respectively. The average number (mean±SD) of eggs per gram (epg) in goats was 276±433 (range =100 to 2,100). In sheep, the average epg was 307±378, with values in individual animals ranging between 100 and 1,900. For the coccidian infestation, the average numbers of oocysts per gram (opg) in goats and sheep were 1180±2663 (range=100 to 100,300) and 1661±9563 (range= 100 to 28,300), respectively. Helminth genera detected in sampled animals were Haemonchus (50.7%), Trichostrongylus (29%), Oesophagostomum (16.4%), Cooperia (5.9%) and Strongyloides (3.4%). Monieza spp. was detected in sheep (5.8%) and goats (0.8%). Coccidial oocysts identified comprised of Eimeria caprina (20.6%), E. granulosa (16.2%), E. marsica (14.3%), E. ovinoidalis (12.4%), E. arloingi , (12.4%), for E. parva (16.2%) and E. christenseni (7.6%). The presence of gastro-intestinal parasites in the study animals calls for formulation of appropriate interventions that hinge on parasite burden profiles as influenced by climatic conditions and variability trends.

A retrospective study was carried out to assess the effect of El Nino on trypanosome infection in cattle. Trypanosome infection was monitored in free grazing dairy cattle before and after El Nino in Dar es Salaam. The study involved 49 smallholder dairy herds with a total of 570 dairy cattle. Trypanosomes were identified by microscopic examination of Giemsa- stained blood smears. The rate of trypanosome infection after El Nino in each location with figures before El Nino in brackets were 24.8% (8.0%) in Makongo juu, 28.0% (8.7%) in Madale, 35.6% (14.9%) in Bunju, and 0.5% (4.9%) in Beach areas. The results also indicated that cattle exposure to tsetse challenge was higher in high altitude parts of Dar es Salaam  compared to low-lying areas after El Nino. The observation suggests that El Nino phenomenon influenced tsetse redistribution in many tsetse endemic areas and the increase in infection rate after El Nino was a result of  increase in tsetse fly population. It is recommended that the effect of  weather changes be taken into consideration when offering animal health and extension services on trypanosomosis control. Key words : Dar es Salaam, El Nino, dairy cattle, trypanosomes, tsetse fly
回顾性研究了厄尔尼诺现象对牛锥虫感染的影响。在达累斯萨拉姆监测了厄尔尼诺前后自由放牧奶牛的锥虫感染情况。该研究涉及49个小奶牛群,共570头奶牛。用吉氏染色血涂片镜检发现锥虫。El Nino后各地区锥虫感染率分别为:马孔戈区24.8%(8.0%)、马代尔区28.0%(8.7%)、文州区35.6%(14.9%)、海滩区0.5%(4.9%)。结果还表明,厄尔尼诺现象发生后,达累斯萨拉姆高海拔地区的牛接触采采蝇的风险高于低洼地区。观察结果表明,厄尔尼诺现象影响了许多采采蝇流行区采采蝇的再分布,厄尔尼诺现象后采采蝇种群数量增加是采采蝇感染率上升的原因。建议在提供控制锥虫病的动物卫生和推广服务时考虑天气变化的影响。关键词:达累斯萨拉姆,厄尔尼诺,奶牛,锥虫,采采蝇

Hides, skins, leather and leather products are most traded commodities in the world and demand is increasing. Countries with large livestock populations have great opportunity to generate revenue from this resource. Studies were conducted in slaughterhouses, tanneries and leather good factories in Tanzania, aimed at determining quantities, qualities, processing and trade of hides and skins. Productions from slaughters are more than 3 million cattle hides, 3 million goatskins and 1 million sheepskins. Collected and exported quantities were 1,174,585 cattle hides, 1,591,990 and 304,167 goat and sheep skins. Companies from these destinations pre-pay livestock traders in advance and collect hides and skins at slaughter. Hides and skins are chrome or vegetable tanned at several industries including Afro Leather Industries Dar es Salaam while Himo Tanners and Planters and Afro Leather Industries produce finished leather. Qualities of hides were low because of flay cuts and brand markings. There is one leather footwear factory at Moshi and small scale leather goods factories in Arusha, Moshi, Mwanza, Dar es Salaam, Dodoma, Singida, Morogoro and in other places by individuals, youth groups, Vocational Education Training Authority (VETA) and Small Industries Organization (SIDO). Hides and skins processing is constrained by high international demand for raw hides and skins, inadequate investment in abattoirs, hides and skins collection and storage facilities and lack of trained personnel. Footwear and leather goods are constrained by lack of factories, competition from used goods, synthetic plastics and uninformed market. Investment in hides, skins and leather industry supported by training programmes has potential to generate great monetary revenue. Keywords : Hides, skin, leather, value chain, slaughter ruminants
兽皮、兽皮、皮革和皮革制品是世界上交易量最大的商品,需求正在增加。拥有大量牲畜的国家有很大机会从这一资源中获得收入。在坦桑尼亚的屠宰场、制革厂和皮革制品厂进行了研究,目的是确定皮革和毛皮的数量、质量、加工和贸易。屠宰场生产的牛皮超过300万张,山羊皮300万张,羊皮100万张。收集和出口牛皮1174585张,山羊、绵羊皮1591990张,304167张。这些目的地的公司提前向牲畜贸易商付款,并在屠宰时收取兽皮。皮革和皮肤是铬或植物鞣制在几个行业,包括非洲皮革工业达累斯萨拉姆,而希莫制革和种植园和非洲皮革工业生产成品皮革。由于剥皮和烙印,皮革的质量很低。在莫希有一家皮革制鞋厂,在阿鲁沙、莫希、姆万扎、达累斯萨拉姆、多多马、辛吉达、莫罗戈罗和其他地方有小型皮革制品厂,由个人、青年团体、职业教育训练局(VETA)和小型工业组织(SIDO)经营。生皮和兽皮加工受到以下因素的制约:国际上对生皮和兽皮的高需求、对屠宰场、生皮和兽皮收集和储存设施的投资不足以及缺乏训练有素的人员。由于缺乏工厂、来自二手商品的竞争、合成塑料和不知情的市场,鞋类和皮革制品受到限制。在培训计划的支持下,对兽皮和皮革工业的投资有可能产生巨大的货币收入。关键词:兽皮,皮,皮革,价值链,屠宰反刍动物
