For undergraduate parasitology, we used to run single or dual infections of
T. musculi/P. berghei in mice and Nippostrongilus/Hymenolepis in rats; we
included charcoal/Vermiculite fecal culture with the nematode, and beetles
for growth of cysticercoids for the cestode. None of these infect humans,
so they're safe. Typically, we used stained blood smears from tail snips,
and sacrificed dissected animals analyzed at time intervals, to generate
data. There was usually a variable like experimental groups with and
without quinine/tonic water for malaria, and different inocula sizes, to
illustrate principles like drug screening or niches. Pathologies (e.g.
spleen/liver sizes) and parasite burdens (weight and number of worms, eggs;
parasitemias of tryps or malaria through time) were among the data collected
and written up for a report.
These experiments required a lot of animals, and I'm not sure they would be
justified these days except perhaps as a demonstration. They did give
experience handling animals, writing "papers with real data"; and these
models were easy to maintain.
There are few in-print manuals for lab parasitology; you may have to develop
your own handouts for your chosen experiments/principles. For general
undergrad texts in parasitology, I like Schmidt and Roberts, Marquardt and
Demaree, and Beaver and Young. Molecular parasitology texts tend to be
either collections of review papers or lab manuals that look like baby
Maniatis's, so again you may have to develop handouts for the principles and
experiments you want to emphasize. Good luck!
