Correction to: Effects of challenge dose and inoculation route of the virulent Neospora caninum Nc-Spain7 isolate in pregnant cattle at mid-gestation

Correction to: Vet Res (2019) 50:68 10.1186/s13567-019-0686-3

In the original publication of this article [1], there are errors in the Figure 5, the “ml” should be replaced by “mL” and “IFNγ” should be “IFN-γ” in panels A and B. The corrected Figure 5 is given in this correction.

Figure 5.

IFN-γ production after inoculation with the Nc-Spain7 isolate. Concentrations of IFN-γ, in response to N. caninum soluble extract antigen, in lymphocyte culture supernatants of heifers intravenously challenged with 10⁷ (IV1), 10⁵ (IV2), 10³ (IV3), and 10² (IV4) tachyzoites and the uninfected control group (A), and intravenously (IV2) and subcutaneously (SC) challenged heifers with 10⁵ Nc-Spain7 tachyzoites and the uninfected control group (B). Each point represents the mean log IFN-γ concentration (pg/mL) + SD for each group from 0 to 4 wpi. Notice an enhanced IFN-γ production for IV1 (1 wpi (7 dpi)) and IV2 (2 wpi) groups compared to their basal pre-infection levels (A) and for the intravenous route (B). ****P < 0.0001.

In the main text (on page 11), the sentence ‘However, the foetal death rate using a dose of 10₅ Nc-Spain7 tachyzoites was three times higher for the IV (50.0%; 3/6) route than for the SC route (16.7%; 1/6),…’ should be ‘10⁵ Nc-Spain7 tachyzoites’ here instead of ‘10₅ Nc-Spain7’.

The original publication has been corrected.
