Cattle, worms and zooprophylaxis

Worms

Sir.?I slit. 11 deem it a great, favour if yon will kindly allow me a little space in your well-known journal for the following few lines with a view to draw the attention of your numerous readers to the subject. During the last two years of a practice attending over 20 years I have come across a series of cases suffering from a peculiar kind of worm which fly within a few seconds of their expu...

Worms, Life and Death

I never expected to spend most of my life studying worms. However, when it came time for me to choose an area for my postdoctoral research, I was intrigued both with the problems of neurobiology and with the approaches of genetics. Having heard that a new “genetic organism” with a remarkably simple nervous system was being explored by Sydney Brenner – the microscopic soil nematode Caenorhabditi...

Worms, gaps, and hydras

We define a direct translation from finite rooted trees to finite natural functions which shows that the Worm Principle introduced by Lev Beklemishev is equivalent to a very slight variant of the well-known Kirby-Paris’ Hydra Game. We further show that the elements in a reduction sequence of the Worm Principle determine a bad sequence in the well-quasi-ordering of finite sequences of natural nu...

Zooprophylaxis as a control strategy for malaria caused by the vector Anopheles arabiensis (Diptera: Culicidae): a systematic review

BACKGROUND Zooprophylaxis is the use of wild or domestic animals, which are not the reservoir host of a given disease, to divert the blood-seeking malaria vectors from human hosts. In this paper, we systematically reviewed zooprophylaxis to assess its efficacy as a malaria control strategy and to evaluate the possible methods of its application. METHODS The electronic databases, PubMed Centra...
