Obstaja cela vrsta divjih rastlin, za katere je bilo ugotovljeno, da so strupene za konje. Ena najpogostejših in zlasti strupenih vrst je smrtonosna rastlina pastirja ali Atropa belladonna.

Nightshade je konjem naravno neprijeten in praviloma nimajo raje okusa te rastline kot druge pašne hrane. Pogosteje ga jedo nenamerno, ko se deli rastline uvrstijo v zalogo konja, morda je odpadlo listje iz grma nočne pasti poravnano skupaj s travo ali kadar primanjkuje pašne snovi, ki bi jo konj lahko izbiral. Najbolj strupeni deli rastline so listi in stebla, ki jih najdemo v pašni travi. Stopnja toksičnosti se v jagodah rastline zmanjša, vendar so še naprej strupene in lahko sčasoma nastanejo v sistemu, kar povzroči kronično strupenost.

To lahko prizadene konje katere koli starosti, rastline pa najdemo v številnih okoljih, najpogosteje v gozdnatih predelih, ob cestah, med divjimi rastlinami na kmetijskih zemljiščih in na odprtih pašnikih in poljih.

Simptomi in vrste

• Suha usta
• Anoreksija
• Razširjene zenice (midriaza)
• Sprememba srčnega utripa (tj. Nepravilen tempo ali povečan tempo - tahikardija)
• Občutljivost na svetlobo ali slepota
• Nervoza / prekomerna razdražljivost
• Mišični tresenje
• Mišične konvulzije
• Zaprtje
• Driska
• Dezorientacija
• Izguba koordinacije (ataksija)
• Ležanje (pretirano ležanje)
• Krči
• Smrt (hudi primeri)

Vzroki

Končno bo do zastrupitve prišlo, ko konj zaužije smrtonosno nočno senco (Atropa belladonna). To se lahko zgodi med pašo konja ali nenamerno, če rastlino po naključju zmešamo s konjsko krmo. Ta rastlina vsebuje spojino atropin in ravno ta spojina povzroča zgoraj navedene klinične znake. Atropin je antiholinergični alkaloid. Nastali simptomi se pojavijo kot posledica sposobnosti atropina, da blokira nevrotransmiter, ki nadzoruje funkcije avtonomnega živčnega sistema, kot je delovanje mišic, ter nastajanje tekočine in znoja. V centralnem živčnem sistemu atropin vpliva na čutno zaznavanje in sposobnost organiziranja misli in načrtovanih dejanj.

Diagnoza

Skupaj s popolnim pregledom bo opravljen popoln krvni profil, vključno s klinično kemijsko analizo, popolno krvno sliko in analizo urina. Poseben diagnostični test ni na voljo. Identifikacija rastlinskih fragmentov v prebavilih bo dala dokončno diagnozo, vendar je to pogosto postmortem.

Zdravljenje

Spojina, imenovana neostigmin, preprečuje učinke atropina. Poleg uporabe tega zdravila je potrebna tudi podporna oskrba. Aktivno oglje je treba dajati peroralno, veterinar pa mora dajati IV tekočine.

Življenje in upravljanje

Če ste seznanjeni z rastlinami pastelne pasmine, ki rastejo na vaši posesti ali na lokacijah, ki so dostopne vašemu konju, je najbolje, da te rastline izkoreninite iz bližine.
