Control of brucellosis in Kuwait by vaccination of cattle,sheep and goats withBrucella abortus strain 19 orBrucella melitensis strain Rev. 1

Summary In Kuwait, approximately 12,000 diary cows were vaccinated with a reduced dose of 3×10⁹ Brucella abortus strain 19 and approximately 350,000 sexually mature sheep and goats with a reduced dose of 10⁷B.melitensis strain Rev. 1. Using the criteria of prevaccinal and postvaccinal incidences of antibodies, abortions, and human cases of brucellosis, the programme was very successful. Widespread vaccination of adult animals is the most effective method of controlling brucellosis among cattle, sheep and goats in many countries.

Utilizando los criterios prevacunales de incidencia de anticuerpos, abortos, y casos humanos de brucelosis, el programa fuvo gran exito. Ef método mas efectivo de control de la brucelosis bovina, ovina y caprina an numerosas paises es la amplia utilización de vacuna en animales adultos.

Assessment of diversity in Podophyllum hexandrum by genetic and phytochemical markers

For successful conservation and domestication of a species, evaluation of its genetic diversity by different markers is important. Morphological characteristics, phytochemical variation and random amplified polymorphic DNA (RAPD) profiles were generated in different accessions of Podophyllum hexandrum in order to determine the genetic diversity. Random amplified polymorphic DNA (RAPD) analysis revealed a high degree of genetic diversity among the accessions used in the study. There was also high diversity in the concentration of marker compounds in the collected samples as revealed by HPLC analysis. It is shown that the approaches used in the work successfully discriminate between the accessions of this species and thus they constitute interesting tools to analyze molecular, biochemical and phenotypic diversity within this species. Similarity measurement using UPGMA followed by cluster analysis resulted in formation of many groups based on geographical distribution that generally reflected expected trends between the genotypes. There were also some important exceptions like PW-S, an accession from Wastoorwan, Khrew showing close resemblance to PG-S and PG-B collected from Gulmarg but grown at two different gene banks at Srinagar and Bonera. Further an accession PSH-B from Keller was significantly diverse from the rest of the native genotypes phytochemically, morphologically and at molecular level. RAPD data analysis was found to be significant predictor of phytochemical markers in cultivated P. hexandrum germplasm. Twelve accessions grown in gene bank repository were subjected to RAPD analysis and were assessed for content of podophyllotoxin and podophyllotoxin β-d-glycoside by HPLC. Individual regressions of podophyllotoxin and podophyllotoxin β-d-glycoside by RAPD analysis against HPLC has been found to determine linear values. Strong correlation and a strong association of values of the phytochemical variables and the DNA polymorphism data has been recorded.     

拟南芥花组织高表达TCP家族转录因子At1g30210的克隆与转录激活活性鉴定

Seasonal Changes in Arsenic Concentrations and Hydrogeochemistry of Canadian Creek, Ballarat (Victoria, Australia)

A 10-month study of surface waters in Canadian Creek (Ballarat, Victoria, Australia) showed the significant influence of historic gold mining waste material. The investigation focussed on the hydrogeochemistry of the surface waters and soils in order to: (1) document the levels and seasonal trends in major, minor and trace elements in the creek, (2) identify the process by which As is released from the soil/waste mining material to surface waters. For most dissolved major and trace elements (Na, Ca, Mg, K, and As) in surface waters, the concentrations decreased with the increasing rainfall and flow conditions except for Al and Fe. Two sites selected along the creek (< 1 km apart) allowed evaluation of the possibility that mining waste material is contributing to the elevated As concentrations (up to 145 μg/l) in downstream surface water. Arsenic concentration varied more than 28 fold seasonally and was highest in autumn and lowest in spring. Elevated concentrations of As (up to 1946 mg/kg) at the downstream site indicated the presence of a source of As concentration in both surface and subsurface soils. Oxidation of arsenic sulphides under aerobic conditions with redox fluctuations (7 to 201 mV) could cause elevated As levels in the creek. Significant statistical correlations among the major cations (Ca, Na and Mg) point to a common source(s) resulting in neutral to slightly alkaline (pH ～ 6.5 to 7.8) surface water. Fe and Al secondary phases under oxidising conditions are a significant controlling mechanism for the mobilization of As in highly contaminated soils (> 1500 mg/kg) in the study area. The large As adsorption capacity of Fe and Al could be limiting extreme mobilization into the water. Rainfall with relatively low pH is possibly causing mobilisation of Al, Fe and As from highly alkaline soils (pH ≈ 9.0) into the nearby creek.     

Sero-epidemiology of peste des petits ruminants (PPR) in Pakistan

A sero survey was conducted during 2005-2006 to estimate the sero prevalence of PPR in the small ruminant population of Pakistan. A total of 2798 samples were collected including goats (1979) and sheep (819) from villages in 27 randomly selected districts. These were tested by cELISA for PPRV and true prevalence estimates were calculated by Rogan and Gladen estimator. Overall, 1273 (45.5%) were found positive; 980 (49.5%) of 1979 samples from goats and 293 (35.8%) of 819 serum samples from sheep were positive. The true sero-prevalence of PPR was estimated to be 48.5% (95% CI, 46.6-50.3), and 52.9% (95% CI, 50.7-55.1) and 37.7 (95% CI, 34.4-41.0) for goats and sheep, respectively. PPR virus is widely distributed all across Pakistan and has become an endemic infection of small ruminants. Since it is one of the leading causes of morbidity and mortality in small ruminants, it poses a serious threat to food security and the rural economy in Pakistan.
