Although , and some species are frequently involved in neonatal calf diarrhoea (NCD), detailed studies on their interactions are scarce. Therefore, a cross-sectional study including faecal samples from 404 diarrhoeic calves aged 0-30 days was performed. oocysts and cysts were detected by immunofluorescence antibody test and positive samples were molecularly characterized.

Article Synopsis
  • Paramphistomids, trematodes affecting the rumen, are increasingly found in sheep in northwestern Spain, with 14% of the sheep and 44% of the farms testing positive for infection.
  • The study analyzed 826 fecal samples and identified risk factors such as age, farm management practices, and environmental conditions that influence infection rates and egg shedding of these parasites.
  • Molecular identification confirmed the presence of Calicophoron daubneyi, marking the first time this species has been identified in Spanish sheep, highlighting the growing concern of paramphistomid infections in this region.

Wild lagomorphs can act as reservoirs of several pathogens of public and animal health concern. However, the number of studies assessing the presence of Anaplasma spp. in these species is scarce.

Wildlife is an important reservoir of zoonotic pathogens. The objective of the present study was to assess the importance of wild ungulates in the epidemiology of Rickettsia spp. Ticks and spleen samples were collected from 262 red deer (Cervus elaphus) and 83 wild boar (Sus scrofa) hunted in southwestern Spain over a 5-year period.

Little information is currently available on the occurrence and molecular diversity of the enteric protozoan parasites Cryptosporidium spp., Giardia duodenalis, and Balantioides coli in wild ungulates and the role of these host species as potential sources of environmental contamination and consequent human infections. The presence of these three pathogens was investigated in eight wild ungulate species present in Spain (genera Ammotragus, Capra, Capreolus, Cervus, Dama, Ovis, Rupicapra, and Sus) by molecular methods.
