Abstract: A procedure designed to evaluate the role of low-level administration of phenothiazine in the selection of drug-resistant Haemonchus contortus isolates is described. Haemonchus contortus, from Kentucky (strain B, Drudge et al., 1957a, b) was passed serially into nematode-free lambs for six successive generations. The parasite was propagated in two lines which were exposed to low-level 2- to 3-µ purified phenothiazine from the 2nd to the 11th or from the 10th to the 20th day of its parasitic life in lambs during each generation. Susceptibility of offspring of the sixth-generation worms to single 4-, 7-, or 15-g doses of 2- to 3-µ purified phenothiazine was determined in an attempt to evaluate whether the low-level treatment procedures had caused a significant shift in the original level of susceptibility of the parasite to this test drug. The results obtained suggest that worm populations exposed to low-level treatments for six successive generations were as highly susceptible as a population with no previous exposure to the test drug. |

Cratylia argentea (cratília) is a neo-tropical leguminous plant with high resprouting ability, showing great potential as both an animal feed and to fertilize the soil through its N-fixing ability. During scientific expeditions carried out in 2016 to identify and collect germplasm in different states of Brazil, the Terra Ronca State Park (PETeR) stood out as a potential conservation area for this species. There, cratília is well adapted to the dry season, retaining green leaves even during extended dry periods and was found to develop a shrub or climbing habit, depending on light conditions. In the traditional cattle production systems of the region livestock readily consume cratília, making it an important asset for local inhabitants. Based on several populations identified and collected in PETeR, the value of traditional knowledge and use of cratília is discussed as is the potential role of the Park as an in situ conservation unit. |
