Sychytrium endobioticum inokonzera chirwere chembatatisi. Sychytrium endobioticum iparasite inosungirwa isingaburitse hyphae asi sporangia, iyo ine motile zoospores. Zhizha sporangia dzakatetepa-madziro uye dzinogara kwenguva pfupi. Iyo inoumbwa munyama yembatatisi uye inopa hutachiona hutsva hwezoospore. Spores yekuzororera (dzimwe nguva inonziwo chando sporangia, chando spore, sori yekuzorora kana yechando sori) yakakomberedzwa nemadziro uye inoramba ichishanda kwenguva yakareba kwazvo kunyangwe pasina muenzi. Izvi zvinogona kugadzirwa mumwaka wose wekukura. Vanosunungurwa kubva pakuora warts kupinda muvhu. Kuongororwa kweS. endobioticum kunobata zvese chirimwa, panogona kunge pakaumbwa warts, uye ivhu, iro rinogona
takura zvimedu zvekuzorora.
Mazhinji pathotypes (madzinza) akatsanangurwa mukati S. endobioticum . Izvi zvinotsanangurwa nehutachiona hwavo pamhando dzakasiyana dzembesa dzembatatisi. Pathotype 1 (D1) parizvino haichanyanyi kutaurwa kuti inotapurira mbatatisi muEurope nekuti mashoma mbatatisi anotapukirwa nawo, sezviri pachena nekuda kwekuvapo kwekupokana kwakanyanya mumuridzi. Mamwe ma pathotypes zvino anonzi anoitika kakawanda muWestern Europe, uye anonyanya kuwanikwa munzvimbo dzinonaya mvura yemakomo yeCentral neEastern Europe. Zvinoitikawo kunze kweEurope (semuenzaniso kuNewfoundland, Canada uye muAsia chikamu cheTurkey). Kupokana kune aya pathotypes hakuwanzo, saka kutonga kwakanyanya kuoma. Pathotypes kunze kwe1 (D1) inosiyaniswa kuburikidza nekusiyanisa hutachiona kune chaiyo mbatatisi cultivars, asi neimwe nzira inoita kunge ine hukama hwepedyo kune imwe neimwe pane pathotype 1 (D1). Matanho emukati anokurudzirwa munyika dzeEPPO anoda kuti pathotypes zvizivikanwe.
Kuzivikanwa kwezhizha sporangia kana kuzorora spores inocherechedzwa pasi pe microscope inogona kusimbiswa neyakajairwa PCR,
uye chaiyo-nguva PCR. Yakajairwa PCR yakavakirwa pane yemukati yakanyorwa spacer yeribosomal DNA dunhu (ITS) ine yekumberi primer inonamira kuITS1 uye reverse primer inosungirirwa kuITS2. Iyo chaiyo-nguva PCR yevan Gent-Pelzer et al. (2010) yakavakirwa paITS2. Iyo chaiyo-nguva PCR yaSmith et al. (2014) iyo inotsanangurwa pano inobva padiki subunit (SSU) ribosomal
DNA (18S rDNA). Iyo chaiyo-nguva PCR yakagadzirwa naBonants et al. (2015) inobva pane pathotype 1 (D1) -inobatanidza imwe nucleotide polymorphism (SNP) yakaonekwa uchishandisa Complexity kuderedza kwepolymorphic sequences (CRoPS) kuongorora. Paunenge uchishandisa mbatatisi wart zvinhu, yemukati yakanaka yekuzviparadzanisa yekudzora yakanangana nechirimwa COX gene inoshandiswa kutarisa kushanda kwekuzviparadzanisa nevamwe kweDNA. Pathotype 1(D1) inogona kusiyaniswa kubva pane angangoita pathotypes 2(G1), 6(O1) uye 18(T1) nechaiyo-nguva PCR.
