To determine the most prevalent biovar responsible for brucellosis in sheep and goat populations of Iran, a cross-sectional study was carried out over 2 years in six provinces selected based on geography and disease prevalence. Specimens obtained from referred aborted sheep and goat fetuses were cultured on Brucella selective media for microbiological isolation. Brucellae were isolated from 265...

conclusions the risk of symptomatic hav infection is considerable in adolescents of all studied provinces; thus, universal hav vaccination is recommended for all adolescents, regardless of their socioeconomic level. however, the risk is higher in some provinces, which seem to be transitioning from intermediate to low endemicity. results the weighted prevalence of hav varied significantly across...

sleepy drivers (including those with untreated sleep apnea) must be reported to the relevant motor vehicle licensing authority in some provinces. Such reports have the potential to limit an older person’s independence because, as pointed out by Wolkove and colleagues, there is marked variability within Canada in the coverage for continuous positive airway pressure devices, the treatment of choi...

Studies of foreign direct investment (FDI) distribution in the US is voluminous but such studies on a developing country are rare. We fill the void by analyzing the spatial and temporal variation in FDI among China’s 30 provinces. We believe this is the first study of its kind. Other than some “standard” results, our pooled regression finds that the cumulative FDI has a negative impact on the n...

A biogeographic regionalisation of the Neotropical region is proposed as a hierarchical classification of sub-regions, dominions, provinces and districts. This regionalisation is based on biogeographic analyses of terrestrial plant and animal taxa, and seeks to provide universality, objectivity and stability, such that it can be applied when describing distributional areas of particular taxa or...

Models of economic geography predict that transportation costs directly affect demand for goods and the supply of intermediate inputs. One of the reasons that international trade is concentrated in the coastal provinces of China is that they have lower transportation costs in transporting goods to other countries than do provinces in the interior. This paper examines the relationship between th...

Soil-transmitted helminth (STH) infections, and schistosomiasis and other trematodiases often have a high prevalence in developing countries. Here, we present updated information on the prevalence of these parasites in the Lao People's Democratic Republic (Lao PDR) in 2012, arising from the annual national helminthiasis survey. Fecal specimens were collected from 8,610 inhabitants of 12 provinc...
