The influence of Heligmosomoides polygyrus on infection with Trichinella spiralis was studied in BALB/c mice. Mice coinfected with T. spiralis and previously given H. Polygyrus harboured both nematode species till day 34. The number of T. spiralis muscle larvae was greater in mice coinfected with H. polygyrus/T. spiralis or T. spiralis/H. polygyrus than after infection with T. spiralis alone. Infection with H. polygyrus did not enhance eosinophil and IL-5 levels induced by T. spiralis. Additionally, the production of IgG1 specific to LI T. spiralis was inhibited by co-infection. Changes in the levels of IFN-y and IgG2a implicated a disturbance in Th2 cell activation during protective response and resulted in the greater number of T. spiralis muscle larvae in coinfected mice.
Three cases of prostatitis caused by the invasion of T. vaginalis and C. albicans which has been found in different biological materials were described. After per rectum examination perineum biopsy of prostata was performed in all patients; in histopathological preparations painting at the inflammed reaction of that gland the fungi were detected. Also, the same microorganisms were proved in sexual partners of those patients but multifocal invasion of C. albicans - including genital and urinary organs, mouth and alimentary tract - also in members of their family.
The aim of this study was to evaluate the distribution of intestinal protozoa Cryptosporidium spp. and Giardia spp. among the sled dogs taking part in an international competition during the Dryland World Championship IFSS, in Lubliniec, Poland, April 2005. Fecal samples (n = 80) were collected during the race and during two time periods: 2-4 weeks and 6-8 weeks after the race. The immunofluorescent assay (IFA) MerIFluor Cryptosporidium/Giardia was used for the detection of parasite dispersal stages in condensed samples. The influence of a range of factors on the prevalence and the intensity of cyst/oocyst production was estimated. Giardia spp. infections were identified in four studied countries with overall prevalence of 36%. Cryptosporidium oocysts were detected in samples from 2 of 4 countries with an overall prevalence of 12.5%. For both intestinal protozoa an identical dynamics of infection was noted, with the peak in prevalence and cyst/ oocyst production 2-4 weeks after WC, which supports the hypothesis of the enhanced risk of parasite transmission during the race. The number of dogs in kennels, dog sex, and age affected the Giardia infections in sled dogs. The prevalence or intensity of cyst production were higher in kennels with more than 10 dogs, in males compared to females, and in young (<2 years old) dogs. Cryptosporidium infections were more common among males and young dogs, and the prevalence was low among Husky breeds. The co-infections with both parasites were common and the presence of Giardia or Cryptosporidium infection was significantly connected with the presence of diarrhea in dogs. Consequently, it seems that protozoan infections may affect the physical condition and performance of sled dogs and contribute to zoonotic diseases in dog owners.
The objective of the study was to ascertain the presence of complement binding antibodies against T. vaginalis, T. tenax and hominis in the blood of women with chronic simultaneous (two species) trichomoniasis, and a comparison of the dynamics of antibody formation in the blood of women with one species trichomoniasis. The determinations were made prior to and following the treatment with Fasigyn, in hope to obtain additional data on antigene properties of trichomonas parasites of human organism. The test for complement binding was made for 144 women, 84 of them simultaneously infected with two of the three species of Trichomonas mentioned above and 60 with one. It has been found that in the former the complement binding antibodies attain higher concentrations (except antibodies against T. hominis), and following the Fasigyn treatment in all the cases they return to the normal level later than in respective monospecific trichomoniasis. The highest concentrations of the antibodies, both against T. vaginalis and T. tenax have been found in women with simultaneous trichomoniasis of urogenital system and oral cavity. Lower concentrations of the antibodies against both these species of Trichomonas have been found in women with simultaneous trichomoniasis of both urogenital system and intestine or both intestine and oral cavity. This can be accounted for by a dose antigene relationship between T. vaginalis and T. tenax, and a much more distant relationship of both these species on the one hand and T. hominis on the other.
The authors showed the frequency of occurrence of trichomonadosis and candidosis in 31 842 women living in the Upper Silesia territory. The most extensive invasion of T. vaginalis and C. albicans was found in autumn, and in women 24-34 years old.
Out of 1018 patients calling on parasitologist or stomatologist, 148 (14,5 ± 1%) were found to be infected with Trichomonas tenax. The difficulties with diagnosis of T. tenax were connected fungi infection. Fungi strains isolated from oral cavity of patients infected with T. tenax were differentiated by morphological and biochemical methods.
