Matenda a zomera akuchulukirachulukira akuopseza kupanga chakudya, ndipo angapo mwa iwo sakukhudzidwa ndi mankhwala ophera tizilombo omwe alipo kale. Kafukufuku wa ku Denmark adawonetsa kuti ngakhale m'malo omwe mankhwala ophera tizilombo sakugwiritsidwanso ntchito, nyerere zimatha kutulutsa mankhwala omwe amaletsa tizilombo toyambitsa matenda m'zomera.
Posachedwapa, zapezeka kuti nyerere za ku Africa zokhala ndi miyendo inayi zimakhala ndi mankhwala omwe angaphe mabakiteriya a MRSA. Uwu ndi mabakiteriya oopsa chifukwa sagonjetsedwa ndi maantibayotiki odziwika bwino ndipo amatha kuukira anthu. Akuganiza kuti zomera ndi kupanga chakudya nazonso zikuopsezedwa ndi matenda osagonjetsedwa ndi zomera. Chifukwa chake, zomera zimathanso kupindula ndi mankhwala omwe nyerere zimapanga kuti zidziteteze.
Posachedwapa, mu kafukufuku watsopano womwe wangofalitsidwa kumene mu "Journal of Applied Ecology", ofufuza atatu ochokera ku yunivesite ya Aarhus adawunikanso mabuku asayansi omwe alipo ndipo adapeza kuchuluka kodabwitsa kwa tiziwalo ta nyerere ndi mabakiteriya a nyerere. Mankhwalawa amatha kupha tizilombo toyambitsa matenda tofunikira m'zomera. Chifukwa chake, ofufuzawo akuti anthu amatha kugwiritsa ntchito nyerere ndi "zida" zawo zodzitetezera kuti ateteze zomera zaulimi.
Nyerere zimakhala m'malo okhala ndi anthu ambiri ndipo motero zimakhala pachiwopsezo chachikulu chotenga matenda opatsirana. Komabe, zapanga mankhwala awoawo oletsa matenda. Nyerere zimatha kutulutsa mankhwala opha mabakiteriya kudzera m'maselo awo ndi kukula kwa mabakiteriya.
"Nyerere zimazolowera kukhala m'madera otanganidwa, kotero maantibayotiki ambiri osiyanasiyana apangidwa kuti adziteteze okha ndi magulu awo. Mankhwalawa ali ndi mphamvu yaikulu pa mitundu yosiyanasiyana ya tizilombo toyambitsa matenda m'zomera," anatero Joachim Offenberg wa Institute of Biological Sciences ku Aarhus University.
Malinga ndi kafukufukuyu, pali njira zitatu zosiyana zogwiritsira ntchito maantibayotiki a nyerere: kugwiritsa ntchito mwachindunji nyerere zamoyo popanga zomera, kutsanzira mankhwala oteteza nyerere, ndi kukopera nyerere zomwe zimagwiritsa ntchito maantibayotiki kapena majini a mabakiteriya ndikusamutsa majini amenewa ku zomera.
Ofufuza awonetsa kale kuti nyerere zotchedwa carpenter zomwe "zimasamukira" ku minda ya maapulo zimatha kuchepetsa chiwerengero cha maapulo omwe ali ndi matenda awiri osiyana (kuwola kwa mutu wa maapulo ndi kuvunda). Kutengera kafukufuku watsopanoyu, adawonetsanso kuti nyerere zitha kuwonetsa anthu njira yatsopano komanso yokhazikika yotetezera zomera mtsogolo.
