Epidemiology of Toxocariasis in England and Wales          下载免费PDF全文

Toxocara infection occurs through ingestion of parasite eggs excreted by dogs and cats, and can cause severe morbidity. The burden of disease in England and Wales is not well described, and the impact of public health campaigns conducted in the mid‐1990s is uncertain. This paper uses data from two extensive databases to explore the trends in this disease in England and Wales from the 1970s to 2009.  相似文献   

Induction of immune response in mice with a DNA vaccine encoding outer membrane protein (omp31) of Brucella melitensis 16M     

Gupta VK  Rout PK  Vihan VS 《Research in veterinary science》2007,82(3):305-313

Brucellosis causes serious economic losses to goat farmers by way of reproductive losses in the form of abortions and stillbirths. Nucleic acid vaccines provide an exciting approach for antigen presentation to the immune system. In this study, we evaluated the ability of DNA vaccine encoding the omp31 protein of Brucella melitensis 16M to induce cellular and humoral immune responses in mice. We constructed eukaryotic expression vectors called pTargeTomp31, encoding outer membrane protein (omp31) of B. melitensis 16M. pTargeTomp31 was injected intramuscularly three times, at 3-week intervals in groups of mice 6 weeks of age. pTargeTomp31 induced good antibody response in ELISA . pTargeTomp31 elicited a T-cell-proliferative response and also induced a strong gamma interferon production upon restimulation with either the omp31 antigen or B. melitensis 16M extract. We also demonstrate that animals immunized with this plasmid elicited a strong and long-lived memory immune response. Furthermore, pTargeTomp31 elicited a typical T-helper 1-dominated immune response in mice, as determined by immunoglobulin G isotype analysis. This vaccine also provided the moderate degree of protection to the mice. This study for the first time focuses on DNA immunization of a gene from B. melitensis. These results may lead to the development of a DNA-based vaccine for the control of brucellosis in goats.  相似文献   

Pathologic changes in extrahepatic organs and agglutinin response to Salmonella Gallinarum infection in Japanese quail fed Fusarium verticillioides culture material containing known levels of fumonisin B1

Three hundred 1-day-old Japanese quail (Coturnix coturnix japonica) were divided into two groups of 150 each. One group was maintained on quail mash alone, whereas Fusarium verticillioides culture material (FCM) was added to quail mash in the second group from 5 days of age and supplied 150 mg FB1/kg mash. At day 21, each group was further subdivided into two groups, yielding four groups with 75 birds apiece, which served as the control (group CX), the Salmonella Gallinarum alone group (group CS), the FB1 alone group (group FX), and the group fed FB1 and infected with Salmonella Gallinarum (group FS). An oral challenge with Salmonella Gallinarum organisms (2 x 10(4) colony-forming units [cfu]/ml) was given to groups CS and FS at 21 days of age. Three quail each, were necropsied on day 21 (0 day interval) from groups CX and FX, whereas at subsequent intervals, i.e., 1, 2, 3, 5, 7, 10, 14, and 21 days postinfection (DPI), they were sacrificed from all four groups (CX, CS, FX, and FS) to study the agglutinin response to Salmonella Gallinarum and pathologic changes. The agglutinin titers to Salmonella Gallinarum in the combination group (FS) were generally lower when compared with those in group CS. A reduction in the size of spleen along with depletion of white pulp, thinning of cardiomyocytes, lymphoid cell depletion from bursal follicles, and renal tubular nephrosis were characteristic pathologic changes in group FX. In contrast, there was mild to severe enlargement of spleen accompanied by necrosis and reticuloendothelial cell hyperplasia, pericarditis, myocarditis, and focal interstitial nephritis in groups CS. Similar but more severe lesions were observed in the combination group (FS). In addition, the flabby texture of heart, hydropericardium, and ascites were mainly observed in group FS. It is concluded that continuous presence of fumonisins at 150 mg/kg diet increases the severity of Salmonella Gallinarum infection in young Japanese quail.  相似文献   

Soil respiration in a tropical grassland     

S.R. Gupta  J.S. Singh 《Soil biology & biochemistry》1981,13(4):261-268

Soil respiration throughout an annual cycle was measured at three different stands in a tropical grassland situated at Kurukshetra at 29°58' N lat. and 76°51' E long. Rates of CO₂ evolution were measured by alkali absorption using 13 cm dia × 23 cm aluminium cylinders inserted 10 cm into the ground. Both movable and permanently-fixed cylinders were used. The CO₂ evolution rates for the three stands were: Stand I (dominated by Sesbania bispinosa) 49–358 mg CO₂ m^?2 h^?1; Stand II (mixed grasses) 55–378 mg CO₂m^?2 h^?1; and Stand III (dominated by Desmostachya bipinnata) 55–448 mg CO₂ m^?2 h^?1. A positive significant relation existed between rate of CO₂ evolution and soil water content (r = 0.59?0.740), and between soil respiration and temperature (r = 0.58?0.69). A statistical model developed on the basis of the relationship between CO₂ evolution rates and certain abiotic environmental factors showed 69% comparability between the calculated and observed values of soil respiration. The contribution of root and root-associated microorganisms to total soil respiration was estimated at 42% using the relationship between root biomass and CO₂ output from movable cylinders.  相似文献
