Electroencephalography (EEG) is a non-invasive examination method for the assessment of functional central nervous system (CNS) disturbances. In human medicine it has a special importance as a diagnostic tool for epilepsy. Although many studies were done on the use of EEG for diagnostics of canine central nervous system disorders, the technique is still not applied routinely. The purpose of this paper was to review the use of the electroencephalography in canine neurological disorders of central nervous system diagnosis and assess the future perspectives of this technique in veterinary medicine.

Introduction: In the present study, some of the commercial fish farms located in the Black Sea region of Turkey, were screened for bacteria between 2012 and 2014.Material and Methods: The bacterial agents isolated from fish were identified by classical biochemical tests and the rapid diagnostic tests (API 20 E and API 20 Strep). All strains were further identified by sequencing of the 16S rRNA genes. The strains were also investigated for resistance to different antimicrobials by the disc diffusion method. Antibiotic resistance genes, including tetracycline (B), β-lactam (ampC, blaTEM, blaPSE), florfenicol (floR), erythromycine (ereA, ereB), sulphonamide (sulI, sulII), and trimethoprim (dhfr1) genes, were determined by the PCR method.Results:Vibrio anguillarum, Vibrio fluvialis, Photobacterium damselae subsp. piscicida, Pseudomonas luteola, Lactococcus garvieae, Streptococcus iniae, Aeromonas hydrophila, and Yersinia ruckeri were isolated from marine and freshwater cultured fish. According to the results of disc diffusion, all isolates were sensitive to florfenicol, trimethoprim+sulfamethoxazole, oxitetracycline, and enrofloxacin, and resistant to lincomycin, penicillin G, and amoxicillin. Also, sulI, sulII, and floR resistance genes were detected in the bacteria.Conclusion: The results of the study open up the opportunity to perform further investigations which could determine the possible role of ARGs in fish pathogens.

OBJECTIVE To determine values for tear production, horizontal palpebral fissure length (HPFL), eye blink frequency, and intraocular pressure (IOP) in healthy Syrian hamsters (Mesocricetus auratus). ANIMALS 40 healthy adult Syrian hamsters (80 eyes). PROCEDURES Tear production was measured with the phenol red thread test (PRTT), modified Schirmer tear test (mSTT), and endodontic absorbent paper points tear test (EAPPTT). The IOP was measured by use of rebound tonometry. Correlations between test results and body weight were evaluated. RESULTS Mean ± SD values for the IOP, PRTT, EAPPTT, mSTT, HPFL, and blink frequency for all 80 eyes were 4.55 ± 1.33 mm Hg, 5.57 ± 1.51 mm/15 s, 4.52 ± 1.55 mm/min, 2.07 ± 0.97 mm/min, 5.84 ± 0.45 mm, and 1.68 ± 0.43 blinks/min, respectively. For all variables, values did not differ significantly between the right and left eyes or between males and females. There was no correlation between measured variables and body weight.CONCLUSIONS AND CLINICAL RELEVANCE Results for this study provided information on values for the IOP, PRTT, mSTT, EAPPTT, HPFL, and eye blink frequency in healthy Syrian hamsters. It was important to determine reference intervals for this species because they commonly are kept as pets or used as research animals.
