I’m not anti vax, but I must clarify a statement you made. You stated that the immunity from mother’s milk is temporary; I have to clarify that it is temporary until she stops nursing. During the entire nursing relationship the baby enjoys bioactive components to its mother’s milk, that helps in building its immune system; and if mother properly nourishes her child for the entire span that a child needs milk, the child enjoys the immunoglobulin. Also, if the baby contracts something mom is immune to while nursing, mom’s milk can help baby fight it, all the while building their own immunoglobulin profile.
Susceptibility:- The following bacterial species are recognised conjunctival pathogens and may be susceptible to chloramphenicol. However due to the prevalence of acquired resistance to chloramphenicol in these species, the results of susceptibility testing should be taken into account as soon as these are available. If no susceptibility test result is available, the choice of antibacterial agent should be influenced by local information on the likely prevalence of resistance to chloramphenicol in species that are commonly pathogenic in the eye.
