OBJECTIVE To determine whether cell-free DNA (cfDNA) was detectable in CSF samples from dogs, whether CSF sample volume impacted CSF cfDNA concentration measurement, and whether CSF cfDNA concentration was associated with CNS disease category or CSF RBC count (RBCC), nucleated cell count (NCC), or protein concentration, which could aid in the diagnosis of neurologic diseases in dogs. SAMPLE 80 CSF samples collected from dogs with (n = 60) and without (20) clinical neurologic disease between February 2017 and May 2018. PROCEDURES Results for CSF RBCC, NCC, protein concentration, and cfDNA concentration were compared across CSF groups established on the basis of whether they were obtained from dogs with (case groups) or without (control group) clinical signs of neurologic disease In addition, 5 paired CSF samples representing large (3.0-mL) and small (0.5-mL) volumes, were used to evaluate whether sample volume impacted measurement of CSF cfDNA concentration. RESULTS cfDNA was detected in 76 of the 80 (95%) CSF samples used to evaluate parameters across disease categories and in all 5 of the paired samples used to evaluate whether sample volume impacted cfDNA quantification. There were no substantial differences in cfDNA concentrations identified between groups (on the basis of disease category or sample volume), and the CSF cfDNA concentration did not meaningfully correlate with CSF RBCC, NCC, or protein concentration. CONCLUSIONS AND CLINICAL RELEVANCE Although results indicated that the CSF cfDNA concentration could not be used to differentiate between categories of neurologic disease in dogs of the the present study, further investigation is warranted regarding the use of CSF analysis, including sequencing specific cfDNA mutations, for diagnosing and monitoring neurologic disease in dogs.

OBJECTIVE To investigate the activities of gelatinases (matrix metalloproteinase [MMP]-2 and MMP-9) and serine proteases in the colorectal mucosa of Miniature Dachshunds (MDs) with inflammatory colorectal polyps (ICRPs). ANIMALS 15 MDs with ICRPs and 5 dogs with non–ICRP-related large bowel diarrhea (controls). PROCEDURES Zymographic methods were used to evaluate the activities of MMP-2, MMP-9, latent forms of MMP-2 and MMP-9 (pro–MMP-2 and pro–MMP-9), and serine proteases in inflamed and noninflamed tissue samples from MDs with ICRPs and in noninflamed tissue samples from control dogs. The associations of serine protease activities with MMP-2 or MMP-9 activity were also analyzed. RESULTS Activities of pro–MMP-2 and pro–MMP-9 were detected in most tissue samples, regardless of the tissue type, whereas activities of MMP-2 and MMP-9 were not detected in control tissue samples. In the inflamed tissue samples from MDs with ICRPs, the activities of MMP-2, pro–MMP-9, and MMP-9 were significantly higher than those in the noninflamed tissue samples from those dogs. Serine protease activities were significantly higher in the inflamed and noninflamed tissue samples from MDs with ICRP, compared with findings for control tissue samples. A weak correlation was detected between serine protease activities and MMP-9 activity. CONCLUSIONS AND CLINICAL RELEVANCE Study results suggested that gelatinase and serine protease activities are upregulated in the colorectal mucosa of MDs with ICRPs, possibly contributing to the pathogenesis of this disease through the functions of these enzymes in degradation of extracellular matrix and promotion of inflammatory cell migration and inflammatory responses.

This study was planned to assess the possible relationships with pregnancy-associated glycoproteins (PAG) concentrations by the determination of the biomarkers of oxidative stress in the plasma of dairy cattle during the early period of gestation. Materials and Methods: Blood samples were collected from coccygeal vessels in pregnant (n = 54) and nonpregnant (n = 45) cows. Measurement of biomarkers of oxidative stress (LPO, GSH and SOD) was carried out in females using spectrophotometric method.Plasma PAG concentrations increased and continuously over the both periods investigated. There were significant differences between pregnant and non-pregnant groups (P < 0.001). The concentration of SOD were significantly lower (P< 0.05) in pregnant females from day 25 to 35 (7.08 ±0.31 U.ml-1) and day 36 to 50 after AI (6.6 ± 0.29 U.ml-1) compared with non-pregnant cows (7.59 ± 0.35 U.ml-1). Concerning the concentrations of LPO and GSH, the values obtained were also significant lower (P < 0.05) in pregnant females in the period 25-35 days post AI (122.7 ±10.27 μM and 6.46 ±1.24 μmol/min.ml-1, respectively) and 36-50 days post AI (108.05±6.17 μM and 6.2±0.77 μmol/min.ml-1, respectively) than in the non-pregnant females (124.8 ± 12.16 μM and 6.96 ± 0.92 μmol/min.ml-1, respectively).It was observed that the markers of oxidative stress tended to be higher in non-pregnant females compared with pregnant females during the early period of gestation in dairy cattle. Our results suggest the existence of a relationship among the concentration of oxidative stress markers and PAG during early pregnancy.

The aim of this study was to investigate the changes in some biochemical and haematological parameters due to liver damage caused by parasites in sheep infected with Dicrocoelium dendriticum. The study was conducted on 10 healthy sheep and 60 sheep infected with D. dendriticum. After the blood was taken from the sheep brought to the slaughterhouse in Van Municipality, the liver and gall bladder were examined after the slaughter, and the blood of sheep infected with D. dendriticum was brought to the laboratory and examined for some haematological and biochemical parameters.As a result of the examination, some changes were observed in the biochemical and haematological parameters. In statistical analysis: Haematologically compared with the healthy group of sheep infected with D. dentriticum; WBC, Neu, Eo and Mon values were higher than the control group's values, while RBC, Hct, Hb and MCV values were lower and no significant change was found in the Lym level. Results of biochemical parameters of sheep infected with D. dentriticum according to statistical analysis; ALT, AST and GGT values were higher than of the health group sheep, while serum TP, Alb and glucose values were found than lower.As a result; WBC, Neu, Eo, Mon, ALT, AST and GGT levels in infected sheep due to dicrocoeliasis which cause important pathological disorders in liver that have functions such as synthesis, metabolism and detoxification in the organism were found to be significantly higher compared to the same values of the healthy group. It is predicted that these parameters may be useful in determining the degree and prognosis of liver damage and will shed light on the studies to be performed in this field.

Pyometra is an inflammation of the uterus which is characterized by purulent to sanguinopurulent intraluminal contents. Pyometra has been mostly observed in queens older than 6 years but it has no age predilection. The average age of cats with pyometra is between 5 - 7 years. Traditionally queens reach puberty at a bodyweight of 2.3-2.5 kg. Here in this case we have a 5-month-old cat which has not experienced oestrus but yet developed a pyometra. In this case ovariohysterectomy was performed on this queen. The treatment procedure continued with fluid therapy and antibiotics.

This study aimed to determine the anatomical and histological structure of the uterus of the Anatolian wild goat. Measurements were taken from the uterine segments using digital callipers. The animal material consisted of three wild goats of similar ages (2-3 old). The uterus was studied in three sections: Corpus uteri, cornu uteri and cervix uteri. Each section was examined anatomically and histologically.The mean length of cervix uteri was 33.99±1.22 mm, width of the cervix uteri was 13.39±0.92 mm, thickness of the cervix uteri was 8.42±1.68 mm and weight of the cervix uteri was 5.45±0.80 g. The mean corpus uteri length was 29.61±5.14 mm, corpus uteri width was 21.22±1.98 mm, corpus uteri thickness was 9.05±1.45 mm and corpus uteri weight was 4.30±0.77 g. The mean cornu uteri length was 41.34±8.02 mm, the cornu uteri width was 12.49±2.59 mm, the cornu uteri thickness was 6.73±0.86 mm and the cornu uteri weight was 5.46±0.31 g. Histologically, the uterine tissue was consist of three different regions, namely, cervix uteri, corpus uteri and cornu uteri also this parts were composed of endometrium, myometrium and perimetrium layers were located from the inside to the outside.The findings of this study related to the Anatolian wild goat, which contributes to the wildlife diversity in Turkey, however, the population of which has been decreasing due to illegal and uncontrolled hunting or traffic accidents in recent years.

The purpose of this research is to determine the relationship between cystatin C (Cys-C) and some hematologic and biochemical parameters in neonatal calves diarrhea. Materials and In this research the animal material of the study was obtained from different breeds, genders and ages (0-30 days) 10 samples have been taken from healthy neonatal calves and 22 samples from diarrhea calves which didn′t received any medicine. Otherwise, the general examination has been done for all the calves. The levels of hematologic, biochemical and blood gas have been determind for both healthy calves and neonatal calves diarrhea.Results: Depending on the control group, we have observed that the neonatal calves diarrhea hematologic parameters WBC, Neu, Hct, Hb levels (p<0.05) and biochemical parameter BUN (p<0.01) and Cr (p<0.05) level statistically have been increased. On the other hand, Alb (p<0.05) and glucose (p<0.01) levels have been decreased. In term of blood gas analysis and depending on the control group the level of K+ (p<0.05) has been increased, the levels of pH, pO2 and base (p<0.05) have been decreased. We evaluate the Cys-C level in the neonatal calves diarrhea and we have found that Cys-C level is statistically increased this was detected comparing to the control group (p <0.01).In this research the obtained level of Cys-C can be used as normal for calves; statistically there is no relationship between Cys-C and some of the hematologic and biochemical parameters, the Cys-C level in the calves diarrhea is an important parameter it can be used to determine the diagnosis, treatment and prognosis of the disease; but still much more research about the topic should be done.

The aim of this case presentation is to report ectoparasites detected in one red fox. The adaptation of red foxes to urban environments and their increasing number result in an increased risk of transmission of some ectoparasites and pathogens originating from ectoparasites to humans and domestic animals. In this study, one red fox (Vulpes vulpes) which was after a traffic accident was examined for ectoparasites in the Clinic of Hatay Mustafa Kemal University, Faculty of Veterinary. A total 14 flies, 13 ticks and 4 fleas were collected from the red fox. As a result of the microscopic examinations of ectoparasites, Hippobosca longipennis (9 ♀, 5 ♂), Rhipicephalus turanicus (8 ♀, 5 ♂), Ctenocephalides felis (1 ♀) and Pulex irritans (2 ♀, 1 ♂) were identified. With this study, Hippobosca longipennis was recorded from foxes for the first time in Turkey.

The effects of radiation therapy may be potentiated by combining radiation therapy with secondary therapies. Clinically, radiation therapy has been combined with bisphosphonates for treatment of canine appendicular osteosarcoma for years. The objective of this study was to determine if the timing of administration of bisphosphonates in relation to radiation therapy alters clonogenic survival or cell viability of canine osteosarcoma cells in vitro. Canine osteosarcoma cells were treated before administration of radiation, concurrent with radiation, or after radiation. Reduction in clonogenic survival was identified when bisphosphonates were administered post-radiation compared with pre-radiation. No significant differences were identified for cell viability at any time points. Further investigation of the cellular effects of bisphosphonates on canine osteosarcoma cells is warranted. Consideration may be given to administering bisphosphonates 24 h after radiation to reduce replication of canine osteosarcoma cells and possibly prolong the analgesic effects of both treatments.
