Fig. 4 in The life history strategy of a fur seal hookworm in relation to pathogenicity and host health status

Fig. 4. Anemia and mortality are driven by parasite burden. (a) Survival rates of pups with severe hookworm infection was 44.4%, compared to 90.6% survival of pups with mild hookworm infection and 93.4% survival of pups treated with the antiparasitic ivermectin (Log-rank Mantel-Cox test, Χ2 = 44.43, df = 2, P = 5.41 × 10−10). (b) Hemoglobin concentrations were markedly lower in the group with high parasitic burden (severe infection) (ANOVA, F = 31.47, df = 2, P = 2.12 × 10−12). Whiskers represent 95% confidence intervals.
