Updates on the distribution and host spectrum of Dirofilaria repens in the Republic of Uzbekistan

Authors studied the seasonal invasion of yard dogs by socially dangerous bio- and geohelminths on the territory of the Republic of Kabardino-Balkaria. In the Republic of Kabardino-Balkaria, during all seasons of the year, domestic dogs are the source of 9 zoonotic species of helminths, such as Metorchis bilis, Echinococcus granulosus, Dipylidium caninum, Mesocestoides lineatus, Toxocara canis, Ancylostoma caninum, Dirofilaria repens, Dirofilaria imitis и Trichinella spiralis for a person. Quantitative indicators of the extent of invasion caused by socially dangerous helminths of the species Metorchis bilis, Echinococcus granulosus, Dipylidium caninum, Mesocestoides lineatus, Toxocara canis, Ancylostoma caninum, Dirofilaria repens, Dirofilaria imitis и Trichinella spiralis ranging from 13.33% to 60.00%. In autumn, in domestic dogs, socially dangerous helminths of the species Metorchis bilis, Echinococcus granulosus, Dipylidium caninum, Mesocestoides lineatus, Toxocara canis, Ancylostoma caninum, Dirofilaria repens, Dirofilaria imitis и Trichinella spiralis were recorded with large amounts ranging from 6.67% to 40.00%. It was established that in populations of yard dogs, the most frequently recorded species of socially dangerous helminths of zoonotic etiology in all seasons were Echinococcus granulosus, Toxocara canis, Ancylostoma caninum.

The Republic

Dirofilariasis is distinguished by the causative agent provoking dirofilariasis: Dirofilaria immitis and Dirofilaria repens. In the territory of Armenia, dirofilariosis is studied little. The article addresses the evaluation of the spread and prevalence of dirofilariasis in Ararat Province of the Republic of Armenia. The research was focused on herding dogs. The research showed that 100% of cases were caused by D. immitis; the average prevalence among herding dogs in Ararat Province was 16,6%. Most dogs infected with Dirofilaria were aged 3 to 5 years. Therefore, in the territory of Armenia, there is an active local focus of dirofilariasis in carnivores with the active involvement of herding dogs in its spread

In South Africa the modern outlook towards time may be said to have started in 1948. Both the two major observatories, The Royal Observatory in Cape Town and the Union Observatory (now known as the Republic Observatory) in Johannesburg had, of course, been involved in the astronomical determination of time almost from their inception, and the Johannesburg Observatory has been responsible for the official time of South Africa since 1908. However the pendulum clocks then in use could not be relied on to provide an accuracy better than about 1/10 second, which was of the same order as that of the astronomical observations. It is doubtful if much use was made of even this limited accuracy outside the two observatories, and although there may – occasionally have been a demand for more accurate time, it was certainly not voiced.
