From: Characterization of avian influenza H9N2 viruses isolated from ostriches (Struthio camelus)
Assessment of direct contact-mediated transmissibility of the ostrich H9N2 AIVs in guinea pigs. Groups of three SPF guinea pigs were intranasally with 106 EID50 of tested virus and housed in a cage. At 24 h post-inoculation, three naïve guinea pigs were placed in the same cage and co-housed. At 2, 4, 6 and 8 dpi, the nasal washes of the three inoculated animals and three contact animals were collected and tittered by EID50 assay. Each line represents the virus titer from an individual animal. The dashed lines indicate the limit of virus detection.
