NEVILL, E. M., 1975 Preliminary report on the transmission of Parafi/aria bovicola in South Africa. Onderstepoort J. vet. Res. 42 (1), 41-48 (1975) The filarial worm Parafi/aria bovico/a causes streaks of blood on the skins of live cattle and slimy bruise-like lesions on the subcutaneous surfaces of their carcases. To determine the vectors of this worm a field survey was conducted in November 1972 and during the summer of 1973/74 on 6 farms in the Transvaal. A total of 10 093 flies was… 
The epidemiology of Parafilaria bovicola in the Transvaal Bushveld of South Africa.

TLDR
It is concluded that P. bovicola transmission in the Bushveld is not correlated with peak periods of bleeding but rather with high numbers of vector flies, the various species augmenting each other so that transmission may take place almost throughout the year.
Studies on Parafilaria bovicola Tubangui, 1934 III. Pathological changes in infested calves.
More lesions were found in the carcass of an animal that has been naturally infested with Parafilaria bovicola than in one artificially infested with a single subcutaneous injection of infective
The experimental transmission of Parafilaria bovicola to cattle in South Africa using Musca species (subgenus Eumusca) as intermediate hosts.

In controlled experiments in an insect-free stable, cattle became infected with Parafilaria bovicola when Musca lusoria, infected with the larvae of this worm, were allowed to feed on a fresh skin
Evaluation of the efficacy of anthelmintics against parafilariosis in cattle.
TLDR
An anthelmintic test for evaluating the efficacy of compounds for registration for field use and recovery of Parafilaria worms is described, and lesion sizes of treated and control groups of cattle are compared statistically, using appropriate statistical tests.
Parafilaria bovicola Tubangui 1934 from a human eye in Thailand.
TLDR
The filariid nematode was identified as a young adult female Parafilaria bovicola, based on the following characteristics: no alteration of the transverse striations on the anterior end of the body, the terminal anus and the vulva opening is just posterior to the mouth.
The control of Parafilaria bovicola transmission in South Africa.
TLDR
Ovipositional blood spot counts and the ELISA technique for evaluating P. bovicola infection in a herd were compared and were both effective methods, however, best results for the blood spot method are obtained in spring at the peak of the bleeding season whereas theELISA method does not have this limitation.
The development of Parafilaria bovicola in Musca xanthomelas and Musca lusoria.
  • E. M. Nevill

    The Onderstepoort journal of veterinary research
  • 1981
TLDR
In both Musca species, P. bovicola developed in the fat-body cells, mainly of the abdomen, and on reaching the 3rd stage, larvae escaped from the capsules and migrated to the head cavity and proboscis.
Seasonal abundance and distribution of Parafilaria bovicola ovipositional blood spots on cattle in South Africa.
  • E. M. Nevill
  • Biology, Medicine
    The Onderstepoort journal of veterinary research
  • 1984
TLDR
Ovipositional bleeding was strongly seasonal with blood spots first appearing in winter (June), reaching a peak in spring (September-November) and thereafter declining rapidly as summer progressed, and a high female hormone level appears to be associated with the development of immunity.
The effect of arsenical dips on Parafilaria bovicola in artificially infected cattle in South Africa.
  • E. M. Nevill
  • Biology, Medicine
    The Onderstepoort journal of veterinary research
  • 1985
TLDR
It is proposed that arsenic residues in the sub-cutaneous muscle layers increase with repeated dipping until a level toxic to P. bovicola is finally reached, and older cattle would therefore be refractory to infection and their carcasses at slaughter would not be affected.
The colonization and life-cycles of Musca lusoria, Musca xanthomelas and Musca nevilli, vectors of Parafilaria bovicola in South Africa.
TLDR
Musca lusoria showed survival advantages over M. xanthomelas in that its larvae reached the pupal stage at least a day sooner and its adults survived more than twice as long and its life-cycles were similar in the laboratory, except for adult dietary requirements.

TLDR
The present study relates to some observations made from the gravid female with special reference to its anterior end and the histopathology of the skin lesions, as well as comparing specimens of Parafilaria bovicola Tubangui and P. sahaii.

TLDR
A closer examination of the morphology of infective larvae in the vectors of filarial parasites of man in other areas will almost certainly show that the interpretation of infection rates may be complicated by the presence of infections of nonhuman origin.
