abstract for evaluation and identification some of the chamomile species in two genera anthemis and matricaria, morphological and phonological characteristics were used. the experiment was conducted in a randomized completely blocks design (rcbd) with three replicates, sixteen quantitative and qualitative traits were evaluated such as plant height, anthodium diameter, receptacle diameter, ligul...

BACKGROUND Microalgae grown under different nutrient deficient conditions present a good source of natural lipids with applications for several types of biofuels. The expression of acetyl-CoA carboxylase gene can further provide an insight to the mechanisms leading to enhanced lipid production under such stresses. In this study, two nutrients viz. nitrogen and phosphorus were modulated to see i...

The rearing of snails, intermediate hosts of Schistosoma haematobium, S. intercalatum, S. bovis and Fasciola hepatica is the first step to maintain the life cycle of these parasites in laboratory in order to have biological material for the different studies, namely on the systematic biology and immunodiagnostic of schistosomosis and fasciolosis. According to the traditional method, the alga Os...

Studies on bioecology of An. philippinensis a vector of malaria was carried out in eight islands of the Andaman group. It was found that An. philippinensis preferred to rest and bite outdoors. Maximum biting was observed during 1800 to 2100 hrs on both cattle and human bait. The maximum breeding of An. philippinensis was recorded in slow moving stream followed by ponds with vegetation. The bree...

The speed of translatory movement of Beggiatoa alba is governed by temperature in such a way that between 5 degrees and 33 degrees the temperature characteristics micro = 16,100 and micro = 8,400 respectively obtain for the temperature ranges 5 degrees to 16.5 degrees and 16.5 degrees to 33 degrees . The "break" at 16 degrees -17 degrees is emphasized by the occurrence of a wider latitude of va...

the distribution of phytophthora parsiana a high-temperature tolerant newly described species was studied in southern iran and examined its host range in woody perennial plant species in greenhouse condition under high inoculum potential. among different plant species examined, almonds were highly susceptible by different isolates. from 24 woody plants inoculated, the disease severity in descen...

bacillary dysentery, or shigellosis, is a disease of humans in which the colonic epithelium is invaded by bacteria and subjected to inflammatory destruction. the aim of this study was to develop a polymerase chain reaction(pcr) test for detection of virulent shigella spp.. for this purpose, the primers were designed to amplify a 526-bp internal region of the shigella spp. icsa gene, which encod...

3450 bovine from different breeds and ages were clinically examined for the presence of arthritis. 120 cases showed macroscopic evidences of arthritis. mycoplasma spp were isolated from synovial fluid of 21 affected animals. in addition to mycoplasma spp. arcanobacterium pyogenes and staphylococcus epidermidis were isolated from 2 cases. the synovial fluid was markedly increased, straw color, t...
