Wilhelm Otto Daniel Martin Neitz was born in Potgietersrus (now Mokopane), South Africa, on 17 November 1906, the son of a Lutheran pastor. He studied at the Faculty of Veterinary Science, University of Pretoria, and was awarded a BVSc in 1929 and a DVSc in 1945. His research career at the Onderstepoort Veterinary Institute spanned 41 years (1930 - 1971). He was part-time professor of protozoology and virology at the Faculty of Veterinary Science, UP. During 1948 – 1957 and part time professor of protozoology during 1958 – 1968. He was visiting professor at the Freie Universität, Berlin, during the 19602 and at the Universidade Federale do Rio de Janeiro, Brazil, from 1972 to 1979. He died in Pretoria, South Africa, on 18 August 1979.
Dr Neitz was President of the South African Biological Society in 1944. He was a member of the FAO/OIE Expert Panel on Tick-borne Diseases in 1956, and convener of the discussion on ovine and caprine rickettsial diseases at 1968 OIE meeting, Paris. Dr Neitz was editor of the Onderstepoort Journal of Veterinary Research from 1962 to 1969.
CONTRIBUTIONS :
As research officer at Onderstepoort,
Dr Neitz identified plurality of strains of the bluetongue virus, thus explaining
immunological failures. This formed the scientific basis of the current polyvalent
live vaccine. Whilst investigating various forms of tick toxicoses, he discovered
that the enigmatic disease of calves known as sweating sickness is caused by
bite of Hyalomma truncatum ticks. Dr Neitz was internationally recognised
as aresearch expert on theileriosis, inter alia on account of the identification
and description of Theileria parva lawencei, the cause of “buffalo
disease” / “corridor disease”, and pioneering studies on theileriosis in antelopes.
He discovered the first chemotherapeutic cure for heartwater (ehrlichiosis/cowdriosis)
of ruminants in the form of sulphonamides, the first use of this drug against
rickettsial infections of animals and humans. He subsequently developed the
infection and cure method of immunisation against heartwater. Dr Neitz discovered
that development of macroschizonts of Theileria parva parva is suppressed
by tetracyclines, which led other researchers to develop the infection and cure
method of immunisation against East Coast fever.
