ABSTRACT

Abstract Objective. Canine parvovirus is one of the most important diseases of dogs all over the world that threaten their health. This study aimed to determine the prevalence of canine parvovirus in dogs referred to the Small Animal Clinic of Tehran University in Tehran province by genomic method of detection. Materials and methods. Diarrheal stool samples were obtained from 60 dogs during the years 2014-2016 and the presence of CPV was investigated by PCR method. Results. Prevalence of canine parvovirus infection in the studied dogs was 8.33% (5 0f 60). No significant differences between different age groups and breeds were found. However, infection was significantly higher in dogs with hemorrhagic diarrhea (3 of 25), but it was not statistically significant using chi-square test (p>0.05). Conclusions. This study showed that hemorrhagic diarrhea and lack of vaccination may be considered as important symptoms and risk factors for canine parvoviral infection in dogs and Dog owners in Iran should be aware of the fact that vaccination against CPV infection must be done carefully and on schedule to control and prevent the virus.


Resumen Objetivo. El parvovirus canino es una de las enfermedades más importantes en perros en todo el mundo la cual amenaza su salud. El objetivo de este estudio fue determinar la prevalencia del parvovirus canino en perros remitidos a la Clínica de Pequeños Animales de la Universidad de Teherán en la provincia de Teherán por el método de detección del genoma. Materiales y Métodos. Se obtuvieron muestras de heces diarreicas de 60 perros durante los años 2014-2016 y se investigó la presencia de CPV por el método de PCR. Resultados. La prevalencia de infección por parvovirus canino en los perros estudiados fue del 8.33% (5 0f 60). No se encontraron diferencias significativas entre los diferentes grupos de edad y razas. Sin embargo, la infección fue significativamente mayor en perros con diarrea hemorrágica (3 de 25), pero no fue estadísticamente significativa usando la prueba de chi-cuadrada (p>0.05). Conclusiones. Este estudio demostró que la diarrea hemorrágica y la falta de vacunación pueden considerarse como síntomas y factores de riesgo importantes de la infección por parvovirus canino en perros, y que los propietarios de perros en Irán deben ser conscientes del hecho de que la vacunación contra la infección CPV debe hacerse con cuidado y a tiempo para controlar y prevenir el virus.

ABSTRACT

ABSTRACT Objective. Estimate the prevalence and spatial modeling of PPR in the small ruminant population of Chaharmahal and Bakhtiari, Iran, during 2009-2014. Materials and methods. Data were collected from veterinary organization and Offices in Chaharmahal and Bakhtiari province and data analysis was carried out using and IBM SPSS version 22 and Office 2010. For spatial modeling geographic information system (QGIS and PCI-Geomatic) was used. Results. This study showed that the overall prevalence of PPR during the years 2009 to 2014 was 1.37%. Koohrang, Ardal, Lordegan, Ben, Borougen, Shahrekord, Farsan and Kiar cities had the highest prevalence of PPR, respectively. The highest PPR infection rate was observed in the March and goat more affected rather than other ruminants. Conclusions. Our findings provide evidence of a rather common prevalence of PPR and its spatial distribution in Chaharmahal and Bakhtiari province. Using statistical tests for data analysis of PPR and its spatial modeling researchers can predict the incidence of disease in the future and could select appropriate measures of disease control.


RESUMEN Objetivo. Estimar la prevalencia y el modelo espacial de PPR en la población de pequeños rumiantes de Chaharmahal y Bakhtiari, Irán, durante los años 2009-2014. Materiales y métodos. Los datos fueron recolectados de la organización veterinaria y las oficinas en la provincia de Chaharmahal y Bakhtiari y el análisis de datos se llevó a cabo utilizando IBM SPSS versión 22 y Office 2010. Para el sistema de información geográfica de modelado espacial se utilizó QGIS y PCI-Geomatic. Resultados. Este estudio mostró que la prevalencia general de PPR durante los años 2009 a 2014 fue de 1.37%. Las ciudades de Koohrang, Ardal, Lordegan, Ben, Borougen, Shahrekord, Farsan y Kiar tuvieron la mayor prevalencia de PPR, respectivamente. La mayor tasa de infección por PPR se observó en marzo y cabra más afectados que otros rumiantes. Conclusiones. Nuestros resultados proporcionan evidencia de una prevalencia bastante común de PPR y su distribución espacial en Chaharmahal y Bakhtiari provincia. El uso de pruebas estadísticas para el análisis de datos de PPR y su modelado espacial los investigadores pueden predecir la incidencia de la enfermedad en el futuro y podría seleccionar las medidas adecuadas de control de la enfermedad.

ABSTRACT

Context: Vaccinia virus (VACV) is a member of orthopoxvirus genus of the family Poxviridae. VACVs are enveloped, double‑stranded DNA viruses. Several species of this family, for example, molluscum contagiosum, smallpox, deerpox, horsepox, rabbitpox, and VACVs may cause conjunctivitis. Aims: Given the high incidence of keratoconjunctivitis in Iran (approximately 3.6%–53.9%) and insufficient clinical diagnostic measures, laboratory tests for detection of its causes and determination of accurate keratoconjunctivitis/ conjunctivitis prevalence due to different pathogens are essential. Settings and Design: In this research, conjunctival samples collected from 100 patients with keratoconjunctivitis signs were referred to an eye hospital of Iran. Subjects and Methods: After DNA extraction, polymerase chain reaction (PCR) was carried out for detection of VACV. PCR‑positive products were further subjected to DNA sequencing. Statistical Analysis Used: The results were analyzed using Chi‑square test. Results: In this study, 28% of the samples were positive and a statistically significant relationship obtained between working in medical or research laboratories and VACV prevalence (P < 0.05). Conclusions: This study showed a high rate of VACV keratoconjunctivitis, and therefore, further studies for its prevention and control are necessary.
