Soil Acidity and Survival of Hookworm Larvæ. A Critical Commentary
نویسنده
چکیده
An article in a recent issue of this journal by Dr. A. C. Chandler on soil acidity and survival of hookworm.larvae begins as follows: " It is a prevalent opinion that acidity in soil has a tendency to shorten the life of infective hookworm larvae. Hirst (1924), for instance, says "a markedly acid reaction is also most unfavourable to the continued survival of hookworm larvae" and remarks that the most favourable pH reaction for the development of the larvae in cultures from faeces requires investigation." Dr. Chandler assumes, in my humble opinion quite unjustifiably, that soil acid exerts its main effect in the infective stage of the life history of the larva. His whole investigation is based on this erroneous assumption. As far as I know, no competent authority has hitherto suggested that the degree of acidity ordinarily met with in soil has any marked effect on hookworm larvae, once they have developed to the

Soil Acidity and Survival of Hookworm Larvæ. A Reply to Dr. Hirst's Critical Commentary
on survival due to an unfavourably influenced development. I am in full agreement with Dr. Hirst's ideas as amplified in his critical commentary of my paper. I am sorry that Dr. Hirst misinterpreted my paper to the extent of inferring that I assumed that soil acidity exerts its main influence on the infective stage of the life history of hookworm larvae and that my whole investigation was based...

متن کاملDifferential Soil Acidity Tolerance of Tropical Legume Cover Crops
In tropical regions, soil acidity and low soil fertility are the most important yield-limiting factors for sustainable crop production. Using legume cover crops as mulch is an important strategy not only to protect the soil loss from erosion but also to ameliorate soil fertility. Information is limited regarding tolerances of tropical legume cover crops to acid soils. A greenhouse experiment wa...
متن کاملMapping Historic Hookworm Disease prevalence in the southern Us, comparing percent prevalence with percent soil Drainage Type Using GIs
Mapping of Historic US Hookworm prevalence data from the Rockefeller Sanitary Commission (early 1900s) using current GIS (Geographic Information System) software (county shape files) illustrates the extremely high prevalence of hookworm disease (Uncariasis) in the Southeastern US at the time. Some counties in 7 states recorded 50% to 100% of the population with positive screens for hookworm in ...
