Salmonella tifimurium - utachiona hwakakura, nechirwere, kurapwa

Salmonella utachiona tifimurium anozivikanwa somushonga Salmonella enterica serovar typhimurium. Zviri giremu negative, tsvimbo serin'i utachiona pamwe flagella (ruvara bvudzi-kufanana hurongwa), izvo nhengo unotii.

Ainzi Mabhakitiriya - kukonzera poizeni (salmonellosis) muvanhu. It neutachiona zvinokonzerwa nyama yenguruve, yehuku nyama, mazai. Pets anogonawo fambisa nayo.

vari sei Salmonella Classified?

Saka, tiri kuziva tifimurium Salmonella - causative nomumiririri chirwere kudaro ngozi yakafanana salmonella. Mhando salmonella enterica rinoumbwa 6 subspecies:

• enterica;
• salamae;
• arizonae;
• diarizonae;
• houtenae;
• indica.

Enterica subspecies enterica zvinosanganisira salmonella anotevera serogroups:

• A (paratyphi A).
• B (Derby, typhimurium, agona, Heidelberg).
• C (cholerae suis, Newport, muenchen, virchowinfantis).
• D (muDublin, enteritidis, rostock, kuSendai, typhi).
• E (anatum).

Tifimurium Salmonella (S. typhimurium)

View enterica anoonekwa kuti pathogenic kuti vanhu nemhuka uyewo shiri, asi rinonyatsooneka vari vashomanana vavo kuti vanhu. Uye vakawanda nyaya salmonellosis zvawanikwa S. typhimurium.

utachiona vazhinji Salmonella nemishonga inouraya mabhakitiriya ano, uye saka anoparadzirwa munyika yose. Saka, nosocomial salmonellosis - dambudziko chakakomba panguva. Muna 80% nyaya yacho causative nomumiririri nosocomial (nosocomial) salmonellosis - ndiye S. typhimurium.

pathogenicity zvinhu

Uye ngozi akati mhaka chirwere pathogenicity zvinhu zvinotevera:

• Flagella anopa nokukurumidza kwebasa microorganism.
• Kamudzira of utachiona runochengetedzwa kubva phagocytes. Uye nokuda havakwanisi kuti phagocytosis kusimukira sepsis.

• yaingopambwa kupinda chinhu chinoita kuti dzichikunetsa-mahara yakadzika-nhema tishu.
• Nokuda adhesion akanaka (kuda), kupa fibrils, pectins, LP-saccharide yakaoma, asi utachiona iri rakaramba mumuviri.
• Exotoxins (zvibereko kwayakaita) dzichiumbwa manyoka pamwe unozotevera kupera muviri, nokukurumidza vascular permeability.
• Endotoxin inomira kundorwa rokuparadza phagocytosis. It lipopolysaccharide kunzwisisa kuti nokuumba kudhaka. Platelet aggregation mu capillaries zviduku kunotungamirira kuzvimba, ipapo DIC. A secretion pamusoro Na uye Cl kunoderedza kumeso tsandanyama uye kwakawedzera intestinal motility.

How nemishonga kwemabhakitiriya?

Salmonella tifimurium vane kuramba siyana dzezvakatipoteredza zvinhu:

1. Mwedzi mitatu akachengetwa pa nzvimbo tembiricha ukama zvinhu.
2. Makore mana inochengetwa chakaoma faeces yemhuka.
3. Mwedzi mishanu - mumvura, nehafu gore - mu nomukaka zvinhu uye nyama, musi eggshells - kusvikira pamwedzi.
4. Rufu kunoitika chete panguva 100 ° C. Nyama zvibereko kumusoro nemishonga kuti tembiricha inowedzera (paundi nyama inofanira yakabikwa kwemaawa maviri, asi zvino zvinokuchengetedzai). Achibatsirwa salting uye kusvuta Usauraya salmonella.
5. utachiona hwakakura ichi angakudzivisai munhu tembiricha kuderera kusvika -80 ° C.
6. Zviri husingakwanisi UV chiedza.
7. The disinfectant kunodiwa kuti kukurira maminitsi 20 kuuraya utachiona.

Panomuka pakati salmonellosis kuitika kwakacherechedzwa muzhizha, kazhinji akaonekwa mune vana nokuda kusakwana kwavo rokuzvidzivirira muduku.

Zvokurwara pachishandiswa alimentary kutaura neZvapupu uye kuonana-mhuri. Nenzira, zvakakosha pakushandisa mazai kuti kuteerera mhando mapuroteni uye mondo. Kana turbidity, ropa, zvakaora munhuhwi, zai iri kunge kutapukirwa. Waifanira kuraswa, ndiro dira kuiisa chlorine maoko vachifamba kubata. Sipo Muzviitiko izvi hazvirevi kubatsira.

Winter isipi, mukuru hunofa kuonana-mhuri hutachiwana mashandiro kuti nemishonga kuitika zvikonzero uye nokuti zvokudya vakachengeteka centralized.

incubation nguva

The incubation nguva kunotora maawa matanhatu nemasere pazuva, asi kakawanda zviratidzo zvokutanga kuonekwa mukati rokutanga kana maviri pashure nokudya yakasviba chigadzirwa.

Kutyora mvura-munyu muviri nokuda manyoka, chetsoka inova mvura, frothy, smelly, pamwe hanyanisi, zvakafananidzirwa "nomumachakwi madhaka" ane kakawanda munguva kusvikira gumi pazuva kwevhiki kana kupfuura.

The chirwere avamba acutely, kunoratidzwa muutera, lethargy, nyoro abdominal marwadzo (epigastric uye umbilicus). Mudumbu zvinorwadza pamusoro palpation, anzwike kutinhira uye kuzvimba zvinooneka.

Salmonella tifimurium - Laboratory Diagnostics

At chirwere sei anotevera parameters:

• yakawedzera erythrocyte sedimentation zvazvingava;
• leukocytes pamwe iya kuruboshwe;

Utachiona hwakakura dzakaonekwa kubva zvoutachiona zvinwiwa (mutsvina yadzo, ropa, weti, nhengo kukanganiswa) uye kufungira zvigadzirwa bacteriological nzira. Wokupedzisira mugumisiro ndechokuti, sezvo mutemo, wakagadzirwa reshanu.

Pamusoro chirwere pamwe Salmonella tifimurium, zvinotevera zviratidzo:

• fivhiri;
• chills;
• zvakakomba manyoka;
• kurutsa.

mabatiro

chirwere ichi chinogona kuuraya achiri mucheche, vakwegura, uye vari varwere kuderedzwa kutapata. Uye Salmonella ichi ngozi tifimurium.

Treatment ndechokuti aishandisa mishonga uye rehydration. Uyewo varayire antispasmodics, enzayemu kugadzirira, sorbents, antidiarrheals. "Table №4» inoratidza zvokudya.

Zvipatara dziitwe pasi kunyatsoteerera wezvokurapa achitarisirwa, uye resuscitative nezviyero inoshandiswa zvikuru zviitiko. Of sorbents nokuti detoxification muviri zvinokurudzirwa kushandisa zvinotevera zvinodhaka:

• "Enterosgel";
• "Liferana";
• kusashanda kabhoni;
• "Smecta";
• "Enterodeza".

With kakawanda Kuramba kurutsa zviri fanira kudana amburenzi kuitira kudzivirira kupera mvura mumuviri. Murwere Kazhinji ushandiswe "Regidron". tembiricha yakawedzera kunoderedza antipyretics.

Active pamusoro salmonella salmonella enterica mishonga

Antibacterial yomuchipatara vanoshingaira pamusoro salmonella salmonella enterica, kuita "furazolidone" "Ciprofloxacin", "Rifaximin", "nifuroxazide". Asi vanogona chete taurira chiremba, kunhonga munhu chipimo chemushonga uye kufungisisa ezvinhu omurwere, noutachiona salmonella tifimurium.
