Fasciola hepatica is a trematode infecting ruminants worldwide and occasionally affecting other animal species, including humans. It causes significant economic losses. Geographic distribution and patterns of infection must be considered before control and management measures are developed for this parasite. DNA molecular markers are useful for the identification of flukes and elucidation of their genetic evolution. Therefore, the population structure of F. hepatica was studied using this method in sheep in Xinjiang, China. The molecular characteristics, genetic relationships within the population and dispersal patterns of F. hepatica isolates were analysed based on the cox1 and nad1 genes. The population structure of F. hepatica from three regions of Xinjiang was explored and a neutrality test was conducted. The cox1 and nad1 genes have 21 and 42 variable sites, respectively, which can be classified into 34 and 33 haplotypes. Median-joining network and phylogenetic tree analyses showed that there was no significant variation in F. hepatica isolates between the three geographical regions. Analysis of variance revealed that the genetic variation of F. hepatica was mainly present within the populations. The neutrality test indicated that the populations were relatively stable but the Hami population may have undergone short-term expansion. This study revealed for the first time the molecular characteristics, genetic diversity and dispersal patterns of F. hepatica isolates from sheep in Xinjiang, thus providing new insights into the genetic variation and haplotype diversity of F. hepatica from indigenous sheep.

Porcine circovirus 4 (PCV4) was first discovered in 2019 in a herd of pigs with porcine respiratory disease, dermatitis and nephropathy syndrome in Hunan Province, China. It has subsequently been detected in other provinces and in South Korea. In consideration of the potential of the virus to cause an epidemic, rapid, sensitive, and specific detection of PCV4 is needed, as is the facilitation of further epidemiological research through elucidation of the whole genome of PCV4. This study had those two aims. Fifty-five blood samples, two pig tissue samples, nine saliva swabs and one semen sample which all originated from Sichuan province pig farms were analysed. The virus’ genome of 1,770 bp was synthesised artificially based on a Chinese reference strain and primers and probes for the ORF2 gene were designed. Then, the amplified target fragment was cloned into the pMD19-T vector and a series of diluted recombinant plasmids were used to generate a standard curve. An optimised real-time TaqMan PCR method was established. The results of this study showed that the established method is specific for PCV4 but not for other viruses, and has amplification efficiency of 99.6%, a regression squared value (R²) of 1.000 and a detection limit of 2.2×10 DNA copies. This method was shown to be analytically specific and sensitive with a low intra- and inter-assay coefficient of variation (<1.67 %). Of a total of 67 clinical samples tested using the established method, three were shown to be positive (4%). This study confirms the existence of PCV4 in Sichuan and provides a promising alternative tool for rapid detection of PCV4.

Termelioğlu, Levent | Kalender, Hakan | Erat, Serkan
The aim of this study was to investigate vaginal cytology, haematological and hormonal values, the presence of bacteria in the vagina, and the relationship between these findings in different reproductive periods in cats. The study consisted of 30 healthy non-geriatric female cats that had reachedto puberty. The cats were divided into 3 equal groups (each having 10 cats) as estrus, anestrus and pregnant. The vaginal samples for microbiological and cytological examination andthe blood samples for hormonal analysis and hemogram were taken at the same time. A total of 100 vaginal epithelial cells were counted from the random areas of thevaginal cytology samples on the slide. The distributions of the percentages of the counted cells according to the groups were subtracted and compared. While there was no bacterial growth in 9 (30%) animals, bacterial growth was observed in 21 (70%) animals. There were no bacterial growth in 3 (30%), 4 (40%) and 2 (20%) animals inestrus, pregnant and anestrus groups, respectively. Estradiol (E2) level (42.64 ± 10.62 pg/ml) in estrus animals was significantly higher (P<0.001) than E2 level in pregnant and an estrus animals. The progesterone (P4) level of the pregnant group (12.22±9.35 ng/ml) was higher (P<0.001) than the P4 levels of the anestrus (0.84±0.25 ng/ml) and the estrus group (0.58±0.28 ng/ml), while the P4 levels of the estrus and the anestrus groups were similar. Significant differences were detected only in MCV, MCH and MCHC, within 19 blood parameters. MCV values were found to be lower in estrus animals (45.68±3.75femtoliter) than only in pregnant (51.21±4.99femtoliter) animals (P=0.007). The difference in MCH values between the estrus group (14.37±0.84 pg) and the pregnant group (15.62 ± 1.18 pg) (P=0.003) and the difference in MCHC values between the pregnant group (30.66±1.17 g/dl) and the anestrus group (32.42±1.04 g/dl) (P<0.001) were statistically significant. The presented results may help in the planning of future studies and the comparison of the obtained values.

Danyer, Erdem | Bilal, Tanay
This sectional study aims to collect data about feeding practices for pace horses in the Aegean and Marmara regions of Turkey. For this purpose, a questionnaire consisting of 69 free text and multiple-choice questions was developed. The questionnaire was implemented on 29-31 August 2014 by personal interviews and was online on social media for ten months. The questionnaire comprised sections on breeder demographic information, farm condition, feeding habit, and nutritional disease. Fifty volunteer horse owners who had a total of 271 horses have participated in the study. Evaluation of the results focused on nutrition practices. Unfortunately, 46% of the respondents were not rasping their horses’ teeth, and an important part of them was not using supplementary oil (78%) or feed additives (84%). Drinking water after exercise (74%) as well as rotten, mouldy, and bacterially contaminated feed (72%) were reported as the most important colic reason by the responders. Based on the results of our study, educational initiatives are needed to inform pace horse owners about appropriate nutrition and related diseases to increase the pace horse race performance.

In the present multidisciplinary study, the researchers on a field trial performed a Social Network approach and a group of 9 calves (3 males/6 females) aged 10 to 16 weeks. A 24 hours digital camera was used for location registration (X-Y position) and interactions on each calf, both individually and collectively. Based on the simple methodology nearest neighbor matrix positive and negative associations were analyzed. The field study lasted 4 weeks and the maximum interaction day was chosen, when individual calf activity was high. To those of 9 calves solely no 2 was infected with giardiasis on the first week, whereas calves with no:2, 7, and 8 were also infected on the second week. No: 4 and 6 were also infected with a total of 5 calves on the third week. This was followed by the final 6 calves in total infected. During the observation period, both by investigators and camera records, infected calf 2 was in close contact with no: 8 (at morning observation) and a slight degree of contact with no: 3 and 4 which were detected with giardiasis on the third and fourt weeks, respectively. Due to close contact with no: 8, infection was determined on the second week, earlier than others (except no: 7). Calves with no: 1 and 5 were never infected nor determined by PCR, fecal smear, or rapid diagnostic test kits throughout the study. In conclusion, the present authors suggested that social networking might be an important predisposing factor for giardiasis infection among calves.

This study was carried out in order to examine a total of 40 drinking water samples taken from 20 locations selected from Mardin and Van provinces in terms of physical properties, heavy metal and mineral contents and to evaluate the quality of drinking water in accordance with the results obtained. Among the ion and mineral analyses of the samples, arsenic, copper, boron, cadmium, cobalt, manganese, nickel, lead, selenium and zinc analyses were made with Inductively Coupled Plasma and Mass Spectrometer, and magnesium analyses were made with Inductively Coupled Plasma-Optical Emission Spectrometer. Fluoride, chloride, nitrite, nitrate, bromide, sulfate and phosphate analyses were also performed by Dionex ion chromatography. Conductivity, pH, ORP, TDS and minimum salt analyses were performed with the Myron L device. As a result of the study, the difference between the fluoride, chloride, nitrite, nitrate, bromide, boron, cadmium, cobalt, zinc, conductivity, TDS, ORP and temperature values of the water samples of the two provinces was found to be significant. In addition, drinking water containing heavy metals was found to be above the limit values set by the Regulation on Water Intended for Human Consumption, nickel was detected in water samples taken from Van, and phosphate was not detected in samples taken from Mardin. The remarkable issues in water samples taken from 40 different locations in two provinces are presented in articles and it has been emphasized that it is important for the people living in this region to present the detected defects to local governments, environmental and public health units and to eliminate the defects.

Ural, Kerem | Erdogan, Hasan | Erdogan, Songul
Present research was conducted at the University of Aydin Adnan Menderes, Faculty of Veterinary. In a total of 10 cats with pruritic dermatoses were allocated, classified [Feline atopic skin syndrome (FaSs)] and adapted to the retrospective case controlled study on the basis of Polycheck in vitro Allergy Test, clinical signs, dermatoscopic and cytological examination. No prior drug prescription, nor immunosuppressive treatment were evident, which was an inclusion criteria. Complete blood count, serum biochemistry, and endocrine panels were all deemed available on days 0 and 21 for all cats involved. The Feline Dermatitis Extent and Severity Index (FeDESI) and a 10 cm visual analog scale (VAS) were deemed available as relevant prognostic parameters. A three strain invoving soil-based probiotic used via rectal route significantly decreased FEDESI and VAS pruritus scores after 10 days of rectal use. Pre-treament day 0 FEDESI scores (median ± SD) (106.3 ± 41.38), were significantly higher than scores on day 10 (15.3 ± 10.53) switching the severity of the disease to mild status in all cases. Furthermore, day 0 VAS pruritus scores were 7.4 ± 1.78 (mean ± SD) (prior to treatment), whereas owner VAS pruritus score was decreased to 1.3 ± 1.06 (mean ± SD) significantly (p=0.005). It should not be unwise to draw preliminary conclusion that 3 chained soil-based Bacillus probiotic was capable of short term cure for FaSs. Bacillus probiotics with safety usage should be added to therapeutical armamentarium of FaSs.

Left Abomasum Displacement (LDA) is one of the most important metabolic diseases caused by negative energy balance during the early lactation period for high milk efficient cows. This study aimed to investigate the lipid mobilization and oxidative stress parameters in cows with LDA before and after the operation. In this research, cows with LDA (n=16) were divided into three groups that are before operation (pre-op LDA), immediately after the operation (post-op LDA), and on the 10th day after the operation (post-op 10 LDA). Control groups were formed from early lactation cows (n=8) and dry period (n=8). In serum samples collected from the study groups, total cholesterol, HDL and LDL cholesterol, triacylglycerol, free fatty acid (FFA), β-hydroxybutyric acid (BHBA), malondialdehyde (MDA) levels, and AST, GGT activities were determined spectrophotometrically, total antioxidant level (TAS), total oxidant level (TOS) and paraoxonase 1/arylesterase (PON1/ARES)] enzyme activity was measured according to the procedure of the colorimetric kit. Serum TOS and MDA levels increased in cattle with pre-op LDA compared to control groups, and MDA levels decreased to normal levels in both groups after the operation. TAS levels and PON1/ARES activities decreased in cattle with pre-op LDA compared to control groups and increased gradually in post-op groups. Serum total cholesterol, HDL, and LDL cholesterol levels decreased in cattle with pre-op LDA compared to the control groups and did not return to normal levels in the groups with post-op LDA. While BHBA levels and AST activities increased in cattle with pre-op LDA compared to control groups, they reached normal values in cattle with LDA on the post-op 10th day. It has been concluded that in evaluating the diagnosis, treatment, and prognosis of the disease in dairy cows with LDA, oxidative stress parameters such as TAS, TOS, and PON1/ARES may be used together with lipid parameters.

Korkmaz, Deniz | Harem, Ismail Sah
This study aims to establish the light and electron microscopic structure of the pecten oculi in the goose (Anser anser). For this purpose, 12 samples of pecten oculi extracted from 6 goose eyes were used. In the study, it was found that the goose pecten consists of 13-14 pleats. The maximum transversal length of the eye was approximately 10 mm, the corneal diameter was 5 mm, the basal length of the pecten was 7 mm, the apical length was 1.5 mm, and the height of the pecten was 5.55 mm (n=6). In pecten pleats, the mean diameters of two separate vessels, primary and secondary, were 48.94 and 23.36 μm respectively. The primary vessels located at the centre of the pecten pleats were surrounded by the secondary vessels. It was observed that the melanocytes in pleats gradually intensified from basal to apical regions. Pecten covered to the vitreo-pecteneal limiting membrane and, hyalocytes were found on this part. This study revealed that the goose pecten has a structure similar to the avian species in the waterfowl family.

2022
Alıç Ural, Deniz
Zonulin elucidated as a thoroughly known protein, is capable of modulating the gut integrity of intercellular connections. Intestinal permeability and its modulation by zonulin have been well-defined. Zonulin levels could increase in response to several stimuli, i.e. infection/gluten ingestion. Even if the latter occurs, zonulin signals into the body for elevating the permeability of the gut lining, permitting larger molecules to pass through. All aforementioned conditions initiate inflammation. In the present prospective field study, the aim was to determine the specificity of zonulin as a noninvasive selected biomarker of gut barrier function to identify and debug calves suffering from diarrhea. Furthermore, another purpose was to define the appearance of leaky gut (LeaG) among calves with diarrhea. By use of commercially available Bovine Zonulin ELISA test kits with a well-designed methodology all 11 diseased and other relevant healthy calves gave positive test results. Circulating zonulin levels (ng/mL) expressed as (±SEM), there were significant differences (p<0.001) between healthy (26.43±3.528) and diarrheic calves (57.97±4.250). As a preliminary conclusion, it should not be unwise to draw the hypothesis that zonulin levels debug diarrheic calves from healthy ones. Further studies are warranted.
