In addition, some species of protozoans , are in a position to infect ticks even when they exist within the blood of their hosts at such a low stage that no signs of disease could be detected. These pathogenic protozoa can be detected circulating in populations of the cattle hosts and tick vectors with solely low levels of detectable illness in the … Read More
