Reply To: Does Netilas Neshama on Shabbos Only Apply At the Organism Level?

Only organisms and even them only organisms that are visible when born.
Gemra says it is mutar to kill a kinah on shabbos since it isnt born. Rishonim (eg Rashi) explain to mean they spontaneously generate though today the common interpretation is that as far as the eye can see (without microscopic aide) they seem spontaneously generate.
But certainly there is no issur to spray lysol although it is killing organisms or take antibiotics (as far as netilas neshama goes)
