Trichobilharzia Regenti


Presentation

  • In the present study, we compare our findings to the original description of T. regenti by Horák et al.[ncbi.nlm.nih.gov]
  • The present study measured the antibody reactivity and antigen specificity of sera obtained after experimental infection of mice and natural infection of humans.[doi.org]
  • Finally, cercarial extracts from both T. regenti and S. mansoni were able to degrade native substrates present in skin (collagen II and IV, keratin) at physiological pH suggesting that cysteine peptidases are important in the pentration of host skin.[ncbi.nlm.nih.gov]
  • The present study has shown the developmental differences of T. regenti in the natural (ducks) and the abnormal (mice; inbred strains BALB/c, SCID) hosts.[ncbi.nlm.nih.gov]
Weakness
  • It turned out that 5 of these 7 inducing lectins were those which bound strongly to the surface of cercariae; in comparison with these, the binding of MBL was rather weak, while SBA did not react at all.[doi.org]
  • In a group simulating weak infections expected under natural circumstances, the dose for 5 domestic ducks was 100 cercariae per animal (group LD).[doi.org]
  • CNS infections of ducks and mice by T. regenti may lead to the development of various transient or permanent neuromotor symptoms, such as weak to severe leg paralysis and balance/orientation disorders ( 207 , 214 , 215 ).[doi.org]
Swelling
  • In sensitive individuals, intensive itching may be accompanied by fever and local lymph node swelling [ 6 – 8 ]. Antibody response of bird hosts against avian schistosome antigens has not yet been studied in detail.[doi.org]
  • Noticeable swelling of the hand is shown mainly in panel B1. (The figure was created by H. Kulíková and P. Horák.) Diagnosis is rather problematic.[doi.org]
Pain
  • The affected area is warm, swollen, and painful. A pricking, tingling, and sometimes burning sensation leads to discomfort and even insomnia (Żbikowska et al. 2002 ).[doi.org]
Nausea
  • The condition may be accompanied by other symptoms including swollen lymph nodes, diarrhea, nausea, or fever (Horák et al. 2002 ; Żbikowska et al. 2002 ).[doi.org]
  • An attack by many cercariae may be accompanied by generalized reactions, such as limb and lymph node swelling, nausea, diarrhea, and fever ( 7 , 238 ).[doi.org]
Diarrhea
  • The condition may be accompanied by other symptoms including swollen lymph nodes, diarrhea, nausea, or fever (Horák et al. 2002 ; Żbikowska et al. 2002 ).[doi.org]
  • An attack by many cercariae may be accompanied by generalized reactions, such as limb and lymph node swelling, nausea, diarrhea, and fever ( 7 , 238 ).[doi.org]
Regurgitation
  • These proteases are highly expressed in migrating schistosomula [ 50, 51 ] and can get in contact with the adjacent nervous tissue either when the parasite regurgitates (TrCB1.1 as a digestive enzyme, [ 18 ]) or when it struggles through the tissue (TrCB2[doi.org]
Petechiae

Insomnia
  • A pricking, tingling, and sometimes burning sensation leads to discomfort and even insomnia (Żbikowska et al. 2002 ).[doi.org]
Burning Sensation
  • A pricking, tingling, and sometimes burning sensation leads to discomfort and even insomnia (Żbikowska et al. 2002 ).[doi.org]
Tingling
  • A pricking, tingling, and sometimes burning sensation leads to discomfort and even insomnia (Żbikowska et al. 2002 ).[doi.org]

Treatment

  • […] provided by ZooBank scientific name Trichobilharzia regenti status new species Treatment Trichobilharzia regenti ZBK, new species This treatment is a stub.[treatment.plazi.org]
  • Considering levels of TGF-β1, differences were found among astrocyte (K-W test: χ 2  11.61, df  5, P  0.040; Fig. 4e, black bars) and microglia (K-W test: χ 2  15.29, df  5, P  0.009; Fig. 4e, grey bars) cultures undergoing diverse treatment.[doi.org]

  • This treatment resulted in inhibiting both lectin binding to cercarial surface and the glycocalyx shedding. Application of saccharides alone did not stimulate any changes in cercariae.[doi.org]
  • However, repeated and unlimited treatments had a deleterious effect on animal communities. In addition, after repeated exposures, some snails may become resistant to copper sulfate or avoid the treatment by burrowing into the mud ( 322 , 323 ).[doi.org]

  • Therefore, risk assessment and preventive measures (e.g., removing snails from lakes) are extremely important (Chamot et al. 1998 ; Lévesque et al. 2002 ; Caumes et al. 2003 ; Verbrugge et al. 2004 ; Jouet et al. 2008 ).[doi.org]
