Therapeutic potential of cristobalite in the treatment of calf diarrhea.

Calf diarrhea continues to be the major problem of calves in the neonatal period. The effect of zeolites has been increasingly studied in ruminant health in recent years. In the present study, the efficacy of cristobalite, a zeolite, in neonatal calf diarrhea was studied first time. For this purpose, twenty-five neonatal calves with diarrheas were divided into two groups, and Group 1 (n=12) received conventional treatment and Group 2 (n=13) received cristobalite (Zoosorb 10 mg/kg) orally 3 times a day in addition to conventional treatment. Escherichia coli k99 and CS31a, bovine rotavirus and bovine coronavirus were isolated from fecal samples at the beginning of the treatment, on the third day and before discharge. It was determined that the recovery period in Group 2 was 0.95 (20.6%) days shorter than in Group 1 (p⟨0.05) while no viral agents were found on the fifth day in Group 2, viral shedding continued in 4 of 5 calves in Group 1. In conclusion, the study revealed that cristobalite speeds the recovery time and possibly decreases viral shedding in neonatal calf diarrhea, demonstrating a remarkable efficiency in the treatment.

An investigation of the seroprevalence of CrimeanCongo Hemorrhagic Fever and Lumpy Skin Disease in domesticated water buffaloes in northern Turkey.

This study was conducted in Samsun Province of Turkey to investigate the serological status of domesticated water buffaloes for both Crimean-Congo Hemorrhagic Fever (CCHF) and Lumpy Skin Disease (LSD). Serum was collected from a total of 272 water buffaloes from different age groups and both genders; of the total, 48.1% had been vaccinated against LSD with heterologous sheep-goat pox vaccine. The serum samples were individually assessed by using a commercial ID screen enzyme-linked immune-sorbent assay (ELISA) to detect neutralizing antibodies against both CCHF virus and LSD virus. All 272 buffaloes were negative for antibodies against the CCHF virus. All the unvaccinated buffaloes (141) were seronegative for LSD virus but of the 131 vaccinated buffaloes, 10 (7.6%) were seropositive for the LSD virus. In addition, 8.6% of vaccinated animals age >1 year old were seropositive for LSD, whereas the seropositivity was 5.1% for the animals age <= 1 year old. There was no significant difference for seropositivity between male and female animals in the >1 year old or <= 1 year old age groups. When seroprevalances for LSD in the tested water buffaloes are evaluated by gender, there was a significant difference between females (8.6%) and males (0%) in the <1 year old water buffaloes (X2=20.24; P<0.001). Separately, the results of this study indicate that Bafra district water buffaloes are not infected by CCHFV and LSDV and some of the buffaloes that vaccinated with LSDV did not develop sufficient antibodies to protect them after they were vaccinated for the LSD virus. Furthermore, the authors of this study conclude that both the commercially produced vaccine that is currently administered and the vaccination strategy have to be urgently evaluated by the veterinary authorities in Turkey. This is essential in order to combat the spread of LSD virus infection with an effective vaccine and a comprehensive management strategy across Turkey.

The first serological report for genotype C bovine parainfluenza 3 virus in ruminant species of mid-northen Turkey: Traces from the past.

Bovine parainfluenza 3 virus (BPI3V)is one of the most important respiratory pathogens and a leading cause of serious respiratory illnesses in cattle, both independent of and in connection with other pathogens involved in the bovine respiratory disease complex (BRDC). In this study, we aimed to identify the historical circulation of genotype C bovine BPI3V (BPI3Vc) in Turkey using the archival serum samples of domestic ruminants that had been collected from six provinces of northern Anatolia in Turkey between 2009-2010. A total of 896 sera from cattle (n=442), sheep (n=330), and goats (n=124) were randomly selected and screened with a virus neutralization test in order to detect antibodies for BPI3Vc. The overall seropositivity rate was 21.09%, with seropositivity rates for cattle, sheep, and goats of 21.04%, 20.00%, and 24.19%, respectively. Neutralizing antibody titers for selected samples ranged between 1/4 to 1/512. This study represents the first serological study conducted using the first BPI3V isolate of Turkey.

Effect of osteoblast cell culture on the bone implant contact.

PURPOSE: The aim of this study is to acquire an ideal bone implant contact under the cover of osteogenic effect of osteoblasts derived from Mesenchymal Stem Cells (MSCs). MATERIALS AND METHODS: Thirty dental implants were used for this study. Implants were placed in sheep mandibles and defects were created 4 mm coronally in the dental implants. These defects were filled with Platelet Rich Plasma (PRP) in one group and with PRP + Osteoblast Cell Culture (OCC) in another group. No procedure was conducted on the control group defects (empty defect group). Eight weeks later, osseointegration was investigated with Bone Implant Contact (BIC) measurements histomorphologically. Data were checked statistically. RESULTS: The variation of BIC rates between Empty Defect Group and PRP groups was significant (p <0.05). The BIC rate of the PRP group was higher than that of the Empty Defect Group. The variation of BIC rates between Empty Defect Group and PRP + OCC groups was significant (p <0.05). The BIC rate of the PRP + OCC group was higher than that of the Empty Defect Group. The variation of BIC rates between PRP and PRP + MSC groups was significant (p<0.05). The BIC rate of the PRP + OCC group was higher than that of the PRP group. At the end of the 8-week healing period, it was observed that the percentage of BIC was highest in the PRP + OCC group. CONCLUSIONS: Implant-bone connection was better in the OCC-PRP group compared with the PRP group and the empty defect group. The use of OCC-PRP combination was effective on healing. The BIC value was increased significantly by OCC.

Occurrence of ovine herpesvirus type-2 infection in sheep and cattle in Samsun Province, Turkey.

July 2004, a cow with clinical signs of ovine herpesvirus type-2 infection which is known as sheep associated malignant catarrhal fever (SA-MCF) was reported in Samsun Province in Turkey. Blood samples were collected from the suspected cow, 10 sheep housed with it, and from 150 healthy sheep and 29 healthy cattle randomly selected from different places in Samsun Province. Nested polymerase chain reaction (n-PCR) was used to detect ovine herpesvirus type-2 (OvHV-2) DNA in the suspected cow and competitive- ELISA (c-ELISA) kits were used to detect antibodies against OvHV-2. The suspected cow was found to be n-PCR positive and c-ELISA negative. The serological results were as follows: All 10 (100%) of sheep housed with the suspected cow and 18 of 29 (62%) of the randomly selected cattle were found seropositive. All 150 randomly selected healthy sheep were seronegative. The overall percentage of seropositivity was 14.7% (28/190). OvHV-2 DNA was detected in the peripheral blood leucocyte (PBL) samples of the cow and of the 10 sheep housed with the suspected cow.
