Detection of equid herpesviruses among different Arabian horse populations in Egypt

Equid herpesviruses (EHVs) threaten equine health and can cause significant economic losses to the equine industry worldwide. Different equid herpesviruses, EHV‐1, EHV‐2, EHV‐4 and EHV5 are regularly detected among horse populations. In Egypt, monitoring is sporadic but EHV‐1 or EHV‐4 have been reported to circulate in the horse population. However, there is a lack of reports related to infection and health status of horses, likely due to the absence of regular diagnostic procedures. In the current study, the circulation of four infectious equid herpesviruses (EHV‐1, EHV‐2, EHV‐4 and EHV‐5) among different Arabian horse populations and donkeys residing the same farm was monitored. Different samples were collected and DNA was extracted and subjected to quantitative (q)‐PCR to detect the four equid herpesviruses using specific primers and probes. Antibody titres against EHV‐1 and EHV‐4 were tested using virus neutralization test and type‐specific ELISA. The results showed that EHV‐1, EHV‐2, EHV‐4 and EHV‐5 are endemic and can be a continuous threat for horses in the absence of vaccination programs and frequent virus reactivation. There is an urgent need for introduction of active regular surveillance measures to investigate the presence of different equid herpesviruses, and other equine viral pathogens, in various horse populations around Egypt and to establish a standardized cataloguing of equine health status

Autogenous tooth graft with platelet rich fibrin versus autogenous tooth graft only around immediate dental implant

Objective: This trial was conducted to compare between autogenous fresh tooth graft with/without platelet rich fibrin around immediate dental implant. Patients and methods: This controlled randomized clinical trial was carried out on 12 patients over the age of 18 who required dental extractions of single- or multi-rooted teeth, who were also delayed candidates for osseointegrated implants. They were equally divided into two groups; group (1): Autogenous fresh tooth graft around immediate dental implant placement with platelet rich fibrin and group (2): Autogenous fresh tooth graft around immediate dental implant placement without platelet rich fibrin. Results: The mean value of horizontal bone loss in group (1) and group (2) at 6 months 0.077 (0.065 -0.130) and 0.595 (0.450 - 0.690) respectively with statistical significant differences between two groups. While vertical bone loss in group(1) and group(2) at 6 months (0.510(0.480 -0.530) and (1.490(1.400  - 1.640) respectively with statistical significant differences between two groups. The mean value of  implant stability quotient for group (2) at 3 months was 70.50 ± 3.56 ISQ, and increased to 77.67 ± 5.61 ISQ at 6 months, which was statistically significant
