This study is part of the effort to test and to establish Rapid Bioassessment Protocols (RBP) using benthic macroinvertebrates as indicators of the water quality of wadeable streams in south-east Brazil. We compared the cost-effectiveness of sampling devices frequently used in RBPs, Surber and Kick-net samplers, and of three mesh sizes (125, 250 and 500 microm). A total of 126,815 benthic macro...

two different viruses were isolated from sugar beet growing areas in karaj, which caused mosaic symptoms. collected samples were classified in two different groups. the host range of the first group was confined to some species in chenopodiaceae and amaranthaceae families. the sap of infected plants reacted positively with beet mosaic virus antisera in ouchterlony double-diffusion test. electro...

Hepatozoonosis is a protozoal disease caused by various species of Hepatozoon. This parasite is transmitted from tick; the main vector of Hepatozoon canis is usually the brown dog tick (Rhipicephalus sanguineus). However, several species of ticks are disposed as the alternative vectors. Dogs are usually infected by eating the tick or a part of the tick organ infected by the mature oocysts conta...

As a result of flora-systematic studies the Akdarya reservoir, 71 species and varieties (63 species, 16 variations, 1 form) were identified, which belong to 4 departments, 10 orders, 14 families, 24 genera. The composition is dominated by diatoms (Bacillariophyta), consisting 56 varieties, followed detached green (Cyanophyta) - 9 (8 form), yellowish (Xanthophyta) 4, (Chlorophyta) 2 algae. Hormo...
