parasites
Parasite. The word conjures up thoughts of infections and infestations. These nasty critters not only infect humans, but they also infect countless other species. Parasitic protists are the type of organisms that this paper will delve into; more specifically, the phylum Microspora and the hosts that its species infects (Baker, 1982). Many parasitic protists can infect numerous different species of other organisms, but there are some who can only survive and reproduce while they are in one specific species. This concept of a parasitic protist only being able to thrive in a single species or a few select species is referred to as host specificity. Studying host specificity can lead to gaining invaluable information regarding not only the parasitic species, but also the host species that the parasite infects. By learning as much as we can about parasite-host relationships, we may be able to some day manipulate or control the destructive parasite species such as that of microsporids affecting economic aspects including the Nosema bombycis causing pebrine in the Bombyx mori (silkworm caterpillars) and the Nosema apis causing nosema disease in the Apis mellifera (honey bees). These two species (B. mori & A. mellifera) alone pr
2The second study deals with the effects of microsporidium on Lymantria dispar, an unnatural host for these particular microsporidium species. The conductors of the experiment went out to four sites in western Bulgaria and collected larval specimens of the L. The results of this experiment are similar to the experiment second experiment (mentioned above) in that the infections from three isolates were atypical to the infections produced in the microsporidium's natural host. The third study also examined the effects of microsporidia on L. There have been instances in which an organism is introduced into a foreign habitat for the purpose of eradicating another pest species, but the solution species turns out to create a bigger problem than the original pest species. Parasites infect and destroy both animal and plant species throughout the world. According to Stirnadel and Ebert (1997; as sighted by Canter & Lund, 1951, Green, 1974, Mirscle, 1977, Brambilla, 1983, Brunni!ng, Lingemam & Ringelberg, 1992, Vidtmann, 1993, and Ebert 1995), "micro- and macroparasites, as well as epibionts, have a strong potential to regulate their host populations, to alter the outcome of competition, and possibly to maintain co-existence of natural plankton populations. The ponds were manmade and all located within 2 km of each other. This is the biggest problem with using one species against another for our benefit. Several of the microsporidia produced different infections in the L.
