Little is known of the prevalence of Giardia species and genotypes in pre and postweaned domestic pigs. In the present study, a total of 297 pig fecal samples were screened for the presence of Giardia by PCR and genotyped. An overall prevalence of 31.1% (90/289) (25.8, 36.5 CI) was detected. Giardia was detected in 17% (23/123) (11.8-25.6CI) of pre-weaned piglet faecal samples and 41% (64/156) (33.3-48.7 CI) post-weaned faecal samples analysed. Sequence analysis identified assemblage A and E in pre and post-weaned pigs. Assemblage F was identified in one post-weaned pig. Assemblage E was the most prevalent assemblage detected.

Ophthalmic manifestations of dental disease may occur in dogs and cats because of the proximity between posterior maxillary teeth and the orbit. Ophthalmic disorders may be diagnosed promptly, but the initiating dental disease may be overlooked. Inappropriate diagnosis and treatment of dental disease may result in loss of teeth, irreversible vision-threatening ophthalmic disease, or, ultimately, loss of the globe. When ophthalmic examination results are suggestive of a primary dental disorder, thorough examination of the maxillary teeth is imperative to diagnose appropriately the underlying dental disease. Therapy should include treatment of the dental disease and secondary ophthalmic disorders.
