Incisor teeth were clipped with nail clippers at another veterinary clinic 4 days earlier. Owing to a poor prognosis and the health status of the animal, the owner elected for euthanasia. Based on the postmortem results of the oral cavity examination, micro-computed tomography analysis, bacteriology, and histopathology, iatrogenic incisor malocclusion, incisor enamel fractures, dental disease, hepatic lipidosis, chronic purulent gingivitis/periodontitis caused by Fusobacterium nucleatum and Prevotella buccae, and dental caries were determined to be the final, postmortem diagnoses. Patients with acquired dental disease should be screened carefully for periodontitis, as periodontal disease is progressive in nature and early detection, diagnosis, and treatment are essential.

The objective of this article was to present disease prevalence in 1000 pet guinea pigs from private owners divided into three age groups: under two years; between two and five years; and above five years. Medical records of guinea pigs (Cavia aperea f. porcellus) that were presented to the authors' clinic in the period from January 2008 to August 2013 were reviewed. The most commonly diagnosed disease in guinea pigs was dental disease (36.3 per cent), with higher prevalence in the middle age group (P<0.001) and in males (P<0.001) rather than females. Skin problems were seen as the second most common disease (33.3 per cent), with higher prevalence in male guinea pigs (P<0.001) and in animals younger than two years (P<0.001). Ovarian cystic disease was the third most commonly seen disorder, with higher prevalence in females older than two years (P<0.001). Other common health disorders included gastrointestinal stasis, heterotopic ciliary body calcifications, fatty eye and tibiofemoral osteoarthritis. Only 81 guinea pigs from a total of 1000 animals were healthy. This is the first study to describe the disease prevalence in three age groups of pet guinea pigs.

Some of them are important opportunistic pathogens in humans, including three species of genus Encephalitozoon. Intraspecies genetic variation with a different range of hosts is known in Encephalitozoon cuniculi distinguishing four genotypes. Recently, E. cuniculi is often observed in pet animals, mainly E. cuniculi genotype I in pet rabbits. This study described a fatal encephalitozoonosis in a group of pet rodents Steppe lemmings (Lagurus lagurus). The animals were presented with progressive weight loss, aggression, cannibalism, purulent conjunctivitis and hind limb paresis. Death occurred within 48 h after the onset of clinical signs. The group comprised of 15 animals was affected and died within a period of three months. Post-mortal examination did not show any macroscopic changes. Microsporidial vacuoles with typical spores were found in brain and kidney tissues and E. cuniculi DNA in all tested organs. The internal transcribed spacer region (ITS) of rRNA gene showed 100% homology with E. cuniculi genotype III previously identified in dogs, tamarin colonies from zoos, swine, birds and humans. Pet lemmings could represent a new potential source of the infection for their breeders.
