Pests and diseases

Cattle tuberculosis can also infect alpacas: Mycobacterium bovis also causes TB in this species worldwide. Krajewska-Wędzina et al., 2020 detect M. bovis in individuals traded from the United Kingdom to Poland. To accomplish this they develop a seroassay which correctly identifies positive subjects which are false negative for a common skin test. Krajewska-Wędzina et al. also find that alpacas are unusual in mounting a competent early-infection immune response. Bernitz et al., 2021 believe this to generalise to all camelids.
