A 2.5 year old Appaloosa stallion with progressive weight loss and a heart murmur was diagnosed as having vegetative endocarditis of the right atrioventricular valves with a mass in the right atrium. The ultrasonographic appearance of the lesion was characterized by extreme reverberation. On postmortem examination, a 9 cm diameter thrombus was found within the right atrium and auricle, occupying approximately 80% of the chamber volume. Additionally, a lenticular abscess extended throughout the parietal cusp of the right atrioventricular valve. Histologic examination revealed that the lesions were septic with numerous gram positive cocci in short chains, suggestive of Streptococcus equi , and gram negative rods.  相似文献   

A review of antimicrobial peptides: defensins and related cationic peptides     

Evans EW  Harmon BG 《Veterinary clinical pathology / American Society for Veterinary Clinical Pathology》1995,24(4):109-116

Cationic antimicrobial peptides are present throughout the plant and animal kingdoms and bear striking structural and functional similarities across species lines. They provide primitive, nonspecific means of combating a variety of bacteria, fungi, enveloped viruses, and protozoa. Some are also cytotoxic against host cells, including neoplastic cells. Cationic antimicrobial peptides may play various roles in inflammation and tissue repair. Antimicrobial peptides are found in epithelial tissues regularly exposed to microbial attack as well as in cells whose primary function is defense against potential pathogens. They constitute an important part of the nonoxidative antimicrobial arsenal of leukocytes. They are preformed and/or readily synthesized when the cells are stimulated by exposure to pathogens. They exert their effects directly by inserting into membranes of target cells and forming ion channels which increase membrane permeability; however, antimicrobial peptides can also act as opsonins to facilitate phagocytosis. Resistance to defensins is a virulence factor for organisms such as Salmonella sp. The study of cationic antimicrobial peptides is increasing our understanding of innate immunity, inflammation, and the pathogenesis of genetic diseases such as specific granule disease in humans. Therapeutic applications of antimicrobial peptides are currently under investigation.  相似文献

De invloed van enkele milieufactoren op de vatbaarheid van erwten voor Botrytis cinerea     

Tj. P. Wijngaarden  J. Ellen 《European journal of plant pathology / European Foundation for Plant Pathology》1968,74(1):8-11

In a temperature and nutrient experiment with Rondo peas marked differences were observed in the degree of infection of the plants byBotrytis cinerea. After harvesting the ripe plants these differences were clearly expressed in the percentage of seeds with a chalky appearence, due to invasion by the mycelium ofB. cinerea. Comparatively high percentages of chalky peas were found when the plants were grown at a temperature of 20°C during the day and 15°C during the night. Omitting calcium or magnesium from the nutrient solution did not significantly influence the percentage of chalky peas, but omitting potassium from two weeks before flowering until the end of ripening increased the percentage of chalky peas significantly. This suggests that potassium deficiency before and during flowering makes the plant more susceptible toB. cinerea infection.Samenvatting In een temperatuur- en voedingsproef met Rondo erwten werden opvallende verschillen waargenomen in aantasting van de planten doorBotrytis cinerea. Na het oogsten van de rijpe planten kwamen deze verschillen duidelijk tot uiting in het percentage kalkerwten; dit zijn zaden die door het mycelium vanB. cinerea zijn doorwoekerd. Er werden relatief hoge percentages kalkerwten gevonden bij een temperatuur van 20°C overdag en 15°C's nachts. Het weglaten van calcium of magnesium uit de voedingsoplossing had geen betrouwbare invloed op het percentage kalkerwten, maar het weglaten van kalium vanaf 14 dagen voor de bloei tot het einde van de afrijping verhoogde het percentage kalkerwten zeer belangrijk. Dit wijst er op dat kaliumgebrek vóór en tijdens de bloei de planten vatbaarder maakt voorB. cinerea.  相似文献

Effects of dietary electrolyte balance on the chemistry of blood and urine in lactating sows and sow litter performance     

DeRouchey JM  Hancock JD  Hines RH  Cummings KR  Lee DJ  Maloney CA  Dean DW  Park JS  Cao H 《Journal of animal science》2003,81(12):3067-3074

One hundred fifty-three sows (average parity of 2.2) were used to determine the effects of dietary electrolyte balance (calculated as mEq/kg of diet for Na + K - Cl) on sows and their litters during lactation. The sows were fed corn-soybean meal-based diets (1.0% lysine, 1.0% valine, 0.95% Ca, and 0.80% P; as-fed basis) starting on d 109 of gestation and throughout the 21-d lactation experiment. Dietary electrolyte balance (dEB) was 0, 100, 200, 350, and 500 mEq/kg (as-fed basis), well above and below the dEB of 185 mEq/kg found in a simple corn-soybean meal-based lactation diet. To achieve the desired dEB, diets had the following: 1) 1.8% HCl (6 N) and 1.06% CaCl2, 2) 1.0% CaCl2, 3) 0.04% NaHCO3, 4) 1.29% NaHCO3, and 5) 2.54% NaHCO3 (as-fed basis). Increasing dEB increased blood pH (linear and quadratic effects, P < 0.001), partial pressure of carbon dioxide (linear effect, P < 0.001), HCO3- concentration (linear and quadratic effects, P < 0.001), and blood base excess (linear and quadratic effects, P < 0.001). However, increased dEB resulted in lower blood concentrations of K (linear and quadratic effects, P < 0.04), Cl (linear and quadratic effects, P < 0.001), and ionized Ca (linear and quadratic effects, P < 0.001). Changing dEB did not affect ADFI; water usage, litter weight gain; sow weight change; sow backfat change; percentages of CP, lactose, and fat in the milk; percentage of sows returning to estrus; days to estrus; and number of pigs born alive in the subsequent litter (P = 0.06). However, piglet survivability to d 10 and overall was greatest with the lower dEB treatments (linear effect, P < 0.05). The pH (linear and quadratic effects, P < 0.001) and colony forming units of total bacteria (linear effect, P < 0.03) in the urine increased as dEB of the diet was increased. In conclusion, dEB had pronounced effects on the physiological status of sows and decreasing dEB below that in a simple corn-soybean meal-based diet decreased bacterial counts in the urine and increased piglet survivability. However, milk composition, sow and litter weights at weaning, and subsequent rebreeding performance of the sows were not affected by dEB.  相似文献   

Algal dermatitis in cichlids     

Yanong RP  Francis-Floyd R  Curtis E  Klinger RE  Cichra ME  Berzins IK 《Journal of the American Veterinary Medical Association》2002,220(9):1353-8, 1314

Three varieties of a popular African cichlid aquarium species, Pseudotropheus zebra, from 2 tropical fish farms in east central Florida were submitted for diagnostic evaluation because of the development of multifocal green lesions. The percentage of infected fish in these populations varied from 5 to 60%. Fish were otherwise clinically normal. Microscopic examination of fresh and fixed lesions confirmed algal dermatitis, with light invasion of several internal organs in each group. A different alga was identified from each farm. Fish from farm A were infected with Chlorochytrium spp, whereas fish from farm B were infected with Scenedesmus spp. Because of the numbers of fish involved, bath treatments to remove the algae from affected fish from farm B were attempted, with different dosages of several common algaecides including copper sulfate pentahydrate, diuron, and sodium chloride. However, none of these treatments were successful, possibly because of the location of the algae under the scales and within the dermis, and also because of the sequestering effect of the granulomatous response. To our knowledge, this is the first report of algal dermatitis in ornamental cichlids, as well as the first report of Scenedesmus spp infection in any fish.  相似文献
