Can Nasal Vac be used concurrently with premedication (antibiotics or medicated milk replacer) in baby pigs?
Yes. There is reason to suspect that concurrent use of antibiotics and live bacterial vaccines may be defeating the purpose of a given vaccination program. Practically we have not observed this problem with Nasal Vac. Through selection of antibiotics for which the vaccine is resistant, any suspicion of negative interaction between antibiotics and vaccine can be eliminated. Our vaccinal strain has a resistant pattern against seven antibiotics (Ampicillin, Apramycin, Ceftiofur, Clindamycin/Pirlimycin, Penicillin G, Spectinomycin, and Streptomycin). This knowledge allows the veterinarian or herdsman to select from this list of antibiotics to treat endemic disease during the first two weeks without risk of interfering with Nasal Vac colonization. Judicious antibiotic selection requires that the treated disease agent (or organism) be susceptible to these agents, i.e. susceptibility testing.
