Malassezia pachydermatis is an opportunistic yeast found in the ear canal of small animals; however, the current azole-based therapy applied to it has failed to achieve clinical success due to the antifungal resistance. This issue has encouraged the studies in natural products, such as Origanum vulgare (oregano), Origanum majorana (marjoram) and Rosmarinus officinalis (rosemary) essential oils, although their mechanism of action remains unclear. Malassezia pachydermatis specimens deriving from otitis cases in dogs (n = 22) and cats (n = 2) were subjected to CLSI M27-A3. Sorbitol protection and ergosterol effect were analyzed to investigate their mechanism of action. Fungistatic (MIC) and fungicidal (MFC) activities were observed for oregano (MIC$_{90}$/MFC$_{90}$: 0.625 mg/mL); marjoram (MIC$_{90}$/MFC$_{90}$: 2.5 mg/mL) and rosemary MIC$_{90}$/MFC$_{90}$ > 2.5 mg/mL). Oregano showed superior antifungal effect even at lower MIC and MFC values. All three oils acted on cell wall and at complexation to fungal ergosterol. By gas chromatography (GC-FID), carvacrol was the major compound found in oregano (73.9%); 1,8-cineole was for marjoram and rosemary (20.9% and 49.4%, respectively). These findings support the potential use of these essential oils to treat canine and feline otitis caused by Malassezia pachydermatis.

The current study aimed to investigate the association between the morphology of the median sacral crest, variation in the angle of the spinous process of the first sacral vertebra, and the occurrence of sacrocaudal fusion in greyhounds. In this study, 167 sacra from cadavers of greyhounds (previously euthanized for reasons unrelated to this study) were collected, classified into standard and fuses sacra (based on the number of fused vertebrae and type of fusion), and then classified based on the morphology of the median sacral crest into three different types: type F (full crest), type N (when the median sacral crest is incomplete, and type R (when the median sacral crest is present but it was short or reduced). Among the 167 sacra, 91 sacra were used to measure the angle of the spinous process of the first sacral vertebrae (1st SPA). Each of the sacra was digitally photographed using a Nikon D3100 digital camera (Tokyo, Japan) in which the camera was positioned laterally with the lens parallel to the central part of the lateral aspect of the sacrum and on a flat surface of the laboratory bench. Image-Pro Express Version 5.0 imaging software (Media Cybernetics, Silver Spring, Maryland) was used to draw and measure the angles. The angle of the 1st SPA was defined as the angle formed dorsally at the intersection of two lines. The first line was drawn to represent the cranial ridge of the spinous process of the 1st SPA, and the second line was drawn across the most dorsal surface points of the spinous processes of the 1st (S1) and 3rd (S3) sacral vertebrae. Significant (p < 0.001) morphological differences (F, R, N) were found in the median sacral crest, and the prevalence of median sacral crest type R in standard sacra was 35.1% compared to 10% in fused sacra, type F was 41.2% in standard sacra and 10% in fused sacra, and type N was 23.7% in standard sacra and 80% in fused sacra. The angle 1st SPA with median sacral type N was statistically significantly less (more upright) than those in sacra with median sacral type F (P < 0.042). Differences have been found in the median sacral crest and angulation of the spinous process of S1 vertebra in sacra with different types of median sacral crest.

: The aim of this study is to determine the effect of the rangeland quality of Ankara goats fed on some natural rangeland in Ankara on the mohair quality. The research was carried out in 3 different quality natural rangelands in Ankara province. Crude protein, ether extract, Ca, Fe, N, energy contents and digestibility, in vitro gas production, and relative feed values of good quality rangeland plants were the highest compared to other rangelands, but the crude fiber, acid detergent fiber, and neutral detergent fiber were the lowest (p ˂ 0.05). In the study were used a total of 120 animals (20 males, 20 females in each farm) from 3 farms where Angora goats are raised in the region of rangelands. The mohair quality was determined in mohair samples taken from 6 month old, 1.5, and 2.5-year-old animals. Rangeland quality significantly affected mohair lengths, fineness, elasticity, tenacity, and clean mohair yield, in males and females (p ˂ 0.05). The highest values were obtained from goats fed good quality rangeland (p ˂ 0.05). The effect of age on these features was also important. The mohair quality (length, elasticity, tenacity) increased with increasing age (p ˂ 0.05). The effect of the rangeland quality on the nozzle number was not significant, but the effect of age was significant. and, the nozzles number increased with increasing age. The nozzle depth was affected by the rangeland quality and age. The nozzle depth has increased due to the increase in rangeland quality and age. While the mohair Ca, Mg, S, Fe, and N content of male and female goats were higher in goats fed on good quality rangeland, these were lower in goats fed low-quality rangeland (p ˂ 0.05). While mohair Na content positively affected rangeland quality in females (p ˂ 0.01), was insignificant in males.
