Recent outbreaks of infectious neuro-developmental diseases such as congenital Zika syndrome - have led to a demand for prognosis data from animal models. We developed an intra-amniotic injection mice model that allows Zika virus (ZIKV) infected mice to grow to puberty. In this system, ZIKV is injected into the amniotic fluid of pregnant mice and infected embryos thereafter. ZIKV-infected mice show several symptoms of clinical ‘congenital Zika syndrome’, including decreased brain volume and mis-laminated retina. We also evaluated several behavioral functions of these ZIKV-infected mice, for example, after the mice reach puberty, they have visual and motor defects. This technique can be used to screen and evaluate drug candidates and may help evaluate the prognosis of infectious neuro-developmental diseases.

Rat embryo transfer surgeries are becoming more common with targeted nucleases increasing the demand for rat models. This protocol details pre-surgical preparation, improved surgical techniques for placing embryos into the oviduct, and post-surgical care of rats to parturition. Direct application of mouse oviduct transfer protocols results in limited success in the rat. By combining techniques from several widely used protocols in the field, increased yield of live pups born to healthy dams is possible. This protocol is distinct from previously published protocols by the use of a modified anesthesia protocol (Smith et al., 2004), use of analgesia, the addition of peritoneal sutures (Filipiak and Saunders, 2006), incision location and number of transfers per animal (Krinke et al., 2000).
