AbstractBlood parasites of Apodemus agrarius were investigated in Eastern Slovakia during 1998–2005. The following parasitic species were detected: Trypanosoma grosi, Babesia microti-like piroplasms and Bartonella sp. Trypanosoma grosi was the most common species, with an infection prevalence of 12.7%. Trypanosomes were morphologically typical of the lewisi group, however, they were bigger than T. grosi described in A. flavicollis and A. sylvaticus. The differences analysed by nested analysis of variance were statistically significant. Pleomorphism was not observed. Infections with piroplasms were detected only at two sites, with an intensity of infection not exceeding 0.1%. The morphology of the piroplasms was different from those typical of B. microti. Bartonella occurred at two sites in 0.81% of the animals sampled. The prevalence of infection had a seasonal pattern throughout the study years. Trypanosomes occurred from July to November, with a peak in September, piroplasms occurred in May and June, and Bartonella sp. from May to July.

AbstractThe objective of this study was to obtain primary information on the occurrence of blood parasites and intensity of infection in the Dunnock Prunella modularis in the montane region of Slovakia. Altogether 109 birds were examined during the years 2006–2010. The occurrence of Haemoproteus sp., Leucocytozoon fringillinarum and Trypanosoma sp. was documented. Blood parasite prevalences of 45% by microscopic examination and 55% by PCR diagnostics were found. The prevalence of Leucocytozoon sp. was found to be dependent on host sex with males showing a significantly higher intensity of infection with Leucocytozoon. Adult birds showed significantly higher infection prevalence than subadults. The prevalences of both Leucocytozoon sp. and Haemoproteus sp. were significantly dependent on bird age. The intensity of infection with Haemoproteus and Leucocytozoon was positively correlated and higher intensity of infection was confirmed in adult birds then in subadults birds. The prevalence of blood parasites in our samples was significantly higher in comparison to most other studies from different countries of Europe conducted at lower altitudes, indicating that the montane zone is especially favourable for the transmission of Leucocytozoon and Haemoproteus species.

SUMMARYIn mice infected with the intestinal flagellates Giardia muris or Spironucleus muris, together with the blood parasites Babesia microti or Plasmodium yoelii, there is a temporary decrease of flagellate cyst output coincident with the peak of the blood parasite infections, followed by a rapid return to normal levels. This decrease in cyst output is correlated with decreased numbers of trophozoites in the small intestine. The effect on S. muris is more marked than that on G. muris. Neither blood parasites has any effect on the total duration of the flagellate infection and the flagellates do not affect the blood parasites. In mice infected with G. muris or S. muris and P. berghei there is also a decrease in cyst output but this is less apparent than in infections with B. microti or P. yoelii because of the fatal nature of the P. berghei infection. It is suggested that the decrease in cyst output is probably due to changes in the contents of the small intestine or to non-specific immunological factors rather than to specific immunological changes.

AbstractThis study was conducted in two populations of crabs, Cyrtograpsus angulatus and Neohelice granulata from the Bahía Blanca Estuary, in Argentina, to identify risk factors for infection by the acanthocephalan Profilicollis chasmagnathi and to assess the association between infection and mortality of these hosts. Cyrtograpsus angulatus and N. granulata crabs were sampled seasonally over the course of a year, and spring sampling included collection of dead crabs predated by Olrog's gulls in a nearby breeding colony. Potential risk factors for infection were assessed and the number of cystacanth larvae per crab was counted. In C. angulatus, the odds of infection increased by 7% for each millimetre increase in carapace length, and were nearly 17 times greater in crabs sampled from the Olrog's gull feeding area compared with those sampled from nests in the breeding colony. For every millimetre increase in carapace length in N. granulata, the odds of infection increased by 13% in crabs from the breeding colony, and by 32% in crabs from the feeding area. Mean intensity of infection in N. granulata increased by 16.5% for each additional millimetre of carapace width. The level of parasite aggregation was lowest in the largest C. angulatus and highest in N. granulata predated by Olrog's gull. The results show that host size is the most important factor influencing infection prevalence in both crab species and intensity of infection in N. granulata, and suggest the presence of parasite-induced mortality in the populations studied.
