BACKGROUND The objectives of our research were to search for Leishmania species in rodents in Fars province, south of Iran, and to compare molecular with conventional methods for detecting these parasites. METHODS Rodents were captured using live traps and screened for Leishmania species using molecular and conventional methods, including the taking of smears from each ear. Nested PCR was emp...

METHODS A number of 1021 soft ticks were collected from 31 villages including previously reported infected and none-infected TBRF cases and individually examined for the presence of B. p...

The effects of water temperature and ammonia concentration on swimming capacity of brook charr (Salvelinus fontinalis, Mitchill, 1814) were determined by measuring gait transition speed (U(gt), cms(-1)), maximum burst speed (U(max), cms(-1)), tail-beat amplitude (a, cm), tail-beat frequency (f, Hz), maximum acceleration of bursts (A(max), cms(-2)), number of bursts, distance of bursts (cm) and ...
