Cardiac problems are highly fetal diseases among exotic animals, not only in the rabbit which is prone to such diseases but also in the guinea pig (Cavia porcellus). In rodents, imaging studies such as thoracic radiography are more practical and easier to perform than echocardiography. Cardiac size is primarily evaluated using vertebral heart size (VHS) as reported in ferrets and rabbits. We therefore attempted to determine standard cardiac dimensions in the guinea pig by thoracic radiography using VHS. The purpose of this research was getting an indicator of the normal range of male and female, mature and apparently healthy guinea pigs heart. Standard radiographs of the thorax in lateral and ventro-dorsal (VD) views were taken and interpreted. In our study to determine VHS in VD view conventional method was used. In addition to conventional VHS method, two other measurement methods were performed in lateral view. Statistical analyses were performed with a SPSS Software and Mann-Whitney U test to compare results. Mean and standard deviation were also calculated. According to the results, the total average of VHS in lateral view by the first method was 7.80 ± 0.12, by the second method was 7.80 ± 0.16, by the third method was 7.60 ± 0.15 and the total of average of VHS in VD view was 9.20 ± 0.23. According to present research findings, gender had no meaningful effect on the measuring of the heart size. More researches on the same age and the same species guinea pigs are needed for more accurate evaluation.

Euphrates turtle is the only soft shell turtle of Iran, and unfortunately is in danger of extinction due to multiple reasons. Imaging techniques, in addition to their importance in diagnosis of injuries to animals, have been used as non-invasive methods to provide normal anatomic views. A few studies have been conducted to understand body structure of the Euphrates turtle. Since there is only general information about the anatomy of turtle limbs, the normal skeleton of the Euphrates limbs was studied. For this purpose four adult Euphrates turtles were used. Digital radiographic examination was performed by computed radiographic (CR) in dorsoventral (DV) and lateral (L) positions. Spiral CT-scanning was done and 3D images of the bones were reconstructed for anatomical evaluation. For skeletal preparation, the skeleton was cleaned by a combination of boiling and mealworm methods and limbs’ bones were examined anatomically. In the present study, simultaneous anatomic, radiographic and CT studies of bones in individual turtles made us possible to describe bones anatomically and provided comparable and complementary conditions to represent the abilities of the radiography and CT for better understanding of the anatomy. Arrangement and the number of carpal and tarsal bones are used in turtles’ classification. Among the studied species, Euphrates turtle carpal and tarsal bones show the most similarities to the Apolone spinifera.

Canine distemper virus (CDV) creates a very contagious viral multi-systemic canine distemper (CD) disease that affects most species of Carnivora order. The virus is genetically heterogeneous, particularly in section of the hemagglutinin (H) gene. Sequence analysis of the H gene can be useful to investigate distinction of various lineages related to geographical distribution and CDV molecular epidemiology. Since vaccination program is conducted only in large cities of Iran, CD still remains as one of the major causes of death in dogs in this country. In order to monitor H gene, CDV has been detected in 14 out of 19 sampled dogs through the amplification of nucleoprotein (NP) gene in nested-PCR assay. In the next step 665 bp of H gene was amplified in 9 out of 14 NP-gene positive dogs. Phylogenetic analysis distinguished two distinct CDV genotypes in Iran. JN941238 has been embedded in European cluster and JN941239 has been embedded in Arctic cluster. Nucleic analysis has been shown high difference among both Iranian CDV lineages with CDV vaccine strains.
