Introduction The genus of Acanthamoeba comprises of several free-living amoebae and mostly found in environment habitats worldwide. These organisms can infect a variety of mammals, including humans involving brain, eyes, skin, bones and lungs (Armstrong, 2000; Martinez, 1999). The taxonomy of Acanthamoeba is has yet to be established and still under review, although species identification of th...

The Chinese Erhualian is one of the most prolific pig breeds in the world, but it is in danger of being replaced by other exotic pig breeds because of its slow growth rate and high fat content in the body. To obtain some genetic information for conservation, we analysed the Erhualian pigs by using a PCR-RFLP for the calcium-release-channel (CRC) gene, nine polymorphic microsatellites and the co...

Paramecium jenningsi Diller et Earl, 1958 is classified in the so-called “aurelia” subgroup. The original assumption of the monomorphic status of P. jenningsi (Sonneborn 1970) has been repeatedly challenged over the years with the application of increasingly sophisticated methods and knowledge of the geographic distribution of particular strains of this species. Investigations concerning geneti...

background: giardia lamblia is one of the most prevalent intestinal flagellate protozoa that infects a wide range of vertebrate hosts causing severe intestinal disorder in children.this study was performed to determine subspecies of g.lamblia by the pcrrflp method, targeting the glutamate dehydrogenase (gdh) locus, in hospitalized children at urmia mutahhari hospital, west azerbaijan province,i...

The use of polymorphic markers in breeding programmes could make selection more accurate and efficient. A total of 324 individuals from six Iranian cattle populations (Sarabi, Golpayegani, Sistani, Taleshi, Mazandarani, Dashtiyari), F1 Golpayegani × Brown Swiss and Iranian buffalo populations were genotypedfor the Pit-1 HinfI and leptin Sau3AI polymorphisms by the polymerase chain reactio...

G ATA4 is localised on human chromosome 8p23.1-p22 and codes for a zinc finger transcription factor. Mice lacking Gata4 suffer from defective ventral morphogenesis and heart tube formation. 2 This factor therefore targets various genes important for heart development and basic cardiac function. Recently, three GATA4 mutations have been detected in families with congenital heart disease. 4 A mut...

used as an anti-inflammatory herbal medicine in China. We found that L. japonica produced in Henan and Shandong Provinces has the most potent anti-inflammatory effect. The herbs grown in these two provinces are recognized as geo-authentic and possess a higher content of therapeutically effective components in the flowers. The ecological factors for the cultivation of geo-authentic L. japonica h...

Ectomycorrhizal fungi form symbioses with all the major tree species in the boreal forest zone and they are of key importance in nutrient acquisition, plant protection against root pathogens and drought stress. Their diversity and the impacts of forestry practises on these highly important organisms is therefore of great interest. The aim of the study was to describe ectomycorrhizal biodiversit...
