A yeast related ethanol intoxication syndrome in experimental calves: prevention with nystatin 下载免费PDF全文
Wijayasinghe MS Miranda M Smith NE Baldwin RL Wijayasinghe C Har SA 《The Canadian veterinary journal. La revue veterinaire canadienne》1984,25(6):251-252,253
In a calf nutrition-metabolism study in which a high glucose (60% glucose and 3% lard) versus a high fat (23% glucose and 30% lard) milk replacer were compared, a syndrome characterized by anorexia, an unstable gait, depression, a distended abdomen and an odor of alcohol on the breath was observed in some calves. These signs were associated with intoxicating levels of plasma ethanol and the predominance of the yeast species Torulopsis glabrata in gastrointestinal contents of afflicted calves. Nystatin, a yeast inhibitor, was extremely useful in preventing the problem. 相似文献

Epidemics often result in organizational, policy and technical changes within a country. In 1999, an epidemic of campylobacteriosis was reported in Iceland. The recent availability of fresh poultry products in the marketplace was suggested as the source of infection. This paper reports on the context of the epidemic, reviews interventions implemented to prevent campylobacteriosis, and discusses lessons learned. A retrospective study of interventions implemented in Iceland from June 1995 to December 2007 was conducted by interviewing key informants and reviewing Iceland's literature. Cumulative incidence rates of domestic campylobacteriosis by year and average incidence rates per epidemic period were calculated. Interventions included on-farm surveillance of Campylobacter, producer education, enhanced biosecurity measures, changes in poultry processing, a leak-proof packaging policy, a freezing policy for products from Campylobacter-positive poultry flocks, consumer education, and the creation of a legislated inter-organizational response committee. These interventions appear to have collectively contributed to a decrease in campylobacteriosis' incidence rate near pre-epidemic baseline levels. Expert consultations revealed that the implementation of a Campylobacter surveillance program in poultry and the freezing policy were critical to controlling the disease in the Icelandic population. It was also recognized that new multidisciplinary collaborations among public health, veterinary, and food safety authorities and a sustained co-operation from the poultry industry were integral factors to the mitigation of the epidemic. Iceland's response to the campylobacteriosis epidemic is a lesson learned of inter-disciplinary and inter-organizational precautionary public health action in the face of a complex public health issue. 相似文献

A two‐season field experiment was conducted to evaluate the efficacy of diclosulam compared with recommended doses of pendimethalin and oxyfluorfen for weed management in peanut. Persistence of diclosulam in oil, de‐oiled cake, haulm of peanut, and soil was also studied. Diclosulam 22 and 26 g a.i. ha?1, and a weed‐free check had a high pod yield due to more mature pods and their mass. Pre‐emergence application of diclosulam 26 g a.i. ha?1 provided better weed management and enhanced peanut growth and yield with high net returns. Phytotoxicity studies indicated that the diclosulam application did not cause any phytotoxic symptoms (vein clearing, epinasty, hyponasty, wilting, and injury) on leaf tips and leaf surface of peanut. Diclosulam residues in peanut viz. oil, de‐oiled cake, haulm, and soil were below the detection level after harvesting of peanut from the experimental field. Further, germination percentage and seed cotton yield of cotton crop cultivated after peanut were also not affected significantly. 相似文献

Morphological Studies on the Harderian Gland in the Ostrich (Struthio camelus domesticus) on the Embryonic and Post‐natal Period 下载免费PDF全文

The present investigation was performed on 50 ostriches from 28th day of incubation until the 7th month of life. The morphological (morphometric, histological, histometric and histochemical) studies were conducted. Tissue sections were stained with haematoxylin–eosin, methyl green‐pyronin Y, periodic acid–Schiff, alcian blue pH 2.5, aldehyde fuchsin and Hale's dialyzed iron studies. The Harderian gland becomes macroscopically visible on the 28th day of incubation. It is situated in the ventronasal angle of the orbit near inter‐orbital septum, between medial rectus muscle, pyramidal and ventral oblique muscles. The Harderian gland of ostrich is a tubulo‐acinar gland. The acini were composed of tall conical cells which formed a small lumen and were surrounded by myoepithelial cells. These cells had a granular basophilic, vacuolated cytoplasm. Each of the lobes has a system of complex branching ducts – tertiary, secondary and primary. In the III of research group (3rd week of life), the presence of few plasma cells was demonstrated, which were located within acini and tertiary and secondary ducts, whereas the biggest concentration of plasma cells was observed in group IV of research tissue (4th month of life). The dark cells were observed first time in main ducts 72 h after hatching of nestlings (group II). The morphometric and histometric studies showed that the most intensive growth of Harderian gland occurred between the third week and the seventh month of birds' life. The histochemical study indicated the presence of neutral and acidic mucins, glycoproteins and carboxylated acid mucopolysaccharides. 相似文献

Multi scale analysis of the factors influencing wheat quality as determined by Gluten Index 总被引:1,自引:0,他引:1
In recent years, the Israeli wheat industry has suffered from quality problems that can endanger the possibility of using the wheat to produce bread. The aim of this study is to understand how climatic and management factors, such as N fertilization, emergence date and wheat cultivar, affect the Gluten Index (GI) - a main wheat quality parameter in the Israeli commercial market. The study was undertaken at individual producer fields across southern Israel on three different scales: regional, farm, and the field. Overall, 1800 samples of 15 genotypes were collected, over three consecutive seasons, 2006-2008, from commercial fields throughout the area, from experiments conducted in the fields of the Gilat Research Center, and in the fields of Kibbutz Sa’ad. Climatic variables were mapped exclusively and on the basis of maximum temperature and rainfall data, and were collected in the course of the entire season and during certain periods. Relationships between climatic variables and GI were determined by multivariate regression analyses. On regional scale, the ability of explaining the differences was low, while on the farm and field scale, variation explanation was generally higher. The factors that were found to be most influential on wheat quality in southern Israel are: (1) type of variety; (2) negative influence of cumulative temperature stress; (3) negative influence of excess water; and (4) negative influence of excess nitrogen fertilization. It was found that the genotype is the most important factor influencing GI, but environmental and crop management factors also have a strong effect on the frequency and severity of GI depreciation. The probability of GI reduction increases in “too good” (excess fertilization, redundant irrigation) and in “too bad” conditions (water and temperature stress). Hence, when farmers make decisions regarding sowing, applying nitrogen and/or supplemental irrigation, they must also consider quality parameters, such as GI and not only yield quantity. 相似文献
