Neonatal diarrhea is one of the main causes ofpreweaning mortality worldwide. Diarrhea is the result ofthe combination of several factors, including infectiousagents, host immunity, environment and managementprocedures (7). Newborn piglets are susceptible toinfection by several enteric microorganisms, includingvirus, bacteria and protozoans (7). Among viruses, inArgentina porcine rotaviruses (PoRV) groups A, B and Cand transmissible gastroenteritis coronavirus (TGEV) hasbeen described associated with subclinical or severelydiarrheic outbreaks (4,6). Rotaviruses have a dsRNAgenome that contains 11 segments. They are classifiedinto 10 serogroups (A-J) through cross-reactivity ofantigens on the VP6 protein that makes up theintermediate layer of the tripe-layer capsid shell of thevirus (7). Rotavirus group A, B and C are ubiquitous inswine population; however, group A is the mostextensively found on neonatal diarrhea. We perform amultidisciplinary approach in order to clarify an outbreakof a neonatal diarrhea
