Conditions for efficient transformation of Amycolatopsis orientalis (Nocardia orientalis) protoplasts by Streptomyces plasmid cloning vectors were identified. Three streptomycete plasmid origins of replication function in A. orientalis, as do the apramycin resistance gene from Escherichia coli, the thiostrepton resistance gene from Streptomyces azureus, and the tyrosinase gene from Streptomyces...

A ground survey of Transcaspian urial (Ovis orientalis [vignei] arkal) was conducted over a 7-day period in March 2000 on a 113-km portion of the Aktau Buzachinsky Nature Reserve in southwest Kazakhstan. The purpose of the survey was to determine the population status of urial, especially males. A total of 491 urial (183 ewes, 97 rams, 15 lambs, 196 unclassified) were observed. About 70 urial w...

This study aimed to evaluate protection induced by the vaccine candidate B. ovis ΔabcBA against experimental challenge with wild type B. ovis in rams. Rams were subcutaneously immunized with B. ovis ΔabcBA encapsulated with sterile alginate or with the non encapsulated vaccine strain. Serum, urine, and semen samples were collected during two months after immunization. The rams were then challen...

carnivores play great ecological roles in ecosystems because of placing on top of the food pyramid. food habits of large carnivores are associated with important ecological features such as spatial pattern, movement, habitat selection, social structure, geographical distribution and reproductive success. accordingly, in this study was used scat analysis to determine the diet of persian leopards...

Amblyseius orientalis (Ehara) (Acari: Phytoseiidae) is a native predatory mite species in China. It used to be considered as a specialist predator of spider mites. However, recent studies show it also preys on other small arthropod pests, such as Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae). Experiments were conducted to investigate (1) prey preference of A. orientalis between Tetranychu...

The site of Körtiktepe in southeastern Turkey is one few sites the Upper Mesopotamia basin that attests continuous, permanent occupation across boundary from end colder, drier Younger Dryas (YD) into comparatively wetter and warmer Early Holocene (EH). This allows for study degree environmental change experienced on a local level over this as well adaptations occupants undertook response to the...

Brucella ovis infection is associated with epididymitis, orchitis and infertility in rams. Most of the information available on B. ovis and host cell interaction has been generated using murine macrophages or epithelial cell lines, but the interaction between B. ovis and primary ovine macrophages has not been studied. The aim of this study was to evaluate the role of the B. ovis abcEDCBA-encode...

BACKGROUND Thuja orientalis has been traditionally used to treat patients who suffer from baldness and hair loss in East Asia. The present study sought to investigate the hair growth-promoting activity of T. orientalis hot water extract and the underlying mechanism of action. METHODS After T. orientalis extract was topically applied to the shaved dorsal skin of telogenic C57BL/6 N mice, the h...

Aphoristia (= Symphurus) orientalis Bleeker 1879, collected from an unspecified depth and location in Japanese waters, is the first described species of symphurine tonguefish from Indo-Pacific waters. The original description with accompanying illustration is based on the unique holotype specimen and provides limited diagnostic characters for this taxon. Subsequent to its description, the holot...
