We describe here the clinical significance of coinfection with Theileria orientalis and Babesia ovata in cattle. Anemia status in a herd of dairy cattle in Japan was investigated in relation to infection with these parasites. Our findings indicate that while B. ovata infection might not be the primary cause of anemia in the cattle, it may contribute to the clinical development of anemia in anim...

Abstract The aim of this study was to compare the susceptibility body deformities in juveniles 13 common European cypriniform fish, caused by intensive feeding with same commercial dry diet administered at 25°C according a similar schedule. final share individuals malformations differed considerably among species and 0.0-87.0%. Unaffected were only Barbus barbus (L.), Chondrostoma nasus Cyprinu...

Examination of the original literature concerning species of Philometra (Philometridae, Dracunculoidea) parasitic in the abdominal cavity of European cyprinids revealed that P. abdominalis Nybelin, 1928 is a junior synonym of P. ovata (Zeder, 1803), a parasite of cyprinids of the genera Gobio, Phoxinus and Leuciscus. The valid name of the species parasitizing cyprinids of the genera Abramis, Ru...

période de cohabitation dans les greniers après les récoltes du niébé. Abstract : With an automatic image analysis device, we studied the temporal distribution of the locomotor activity of E orientalis and E vuilleti during 24 hours, and over several days to know whether the activity rhythms of these two Eupelmidae play a role in their competitive interactions. The analysis of locomotor activit...

Three pandemics have been attributed to plague in the last 1,500 years. Yersinia pestis caused the third, and its DNA was found in human remains from the second. The Antiqua biovar of Y. pestis may have caused the first pandemic; the other two biovars, Medievalis and Orientalis, may have caused the second and third pandemics, respectively. To test this hypothesis, we designed an original genoty...

Identifying the processes maintaining genetic variability in wild populations is a major concern in conservation and evolutionary biology. Parasite-mediated selection may strongly affect genetic variability in wild populations. The inbreeding depression theory predicts that directional selection imposed by parasites should act against the most inbred hosts, thus favouring genetic diversity in w...

The giant dobsonfly species Acanthacorydalis orientalis (McLachlan, 1899) is endemic to China and is well-known because of its remarkable large adult body size and enlarged male mandibles. However, the immature stages of this species, as well as all other Acanthacorydalis species are poorly known. In this paper we describe the last-instar larvae and pupae of A. orientalis for the first time. As...

Two sibling species, Metellina orientalis (Spassky, 1932) and M. kirgisica (Bakhvalov, 1974), occurring in the Middle East and Central Asia are redescribed and their distributions mapped. The previously unknown male of M. kirgisica is described for the first time. Stridulatory files on male chelicera of Metellina are also documented for the first time. The occurrence of M. kirgisica in Azerbaij...

In the present study, the new biological sources in the form of lichen Usnea orientalis Motyka was screened for its antidermatophytic potential. Six species of dermatophytes were chosen on the basis of their prevalence for antidermatophytic assays, and the Clinical Laboratory Standard Institute (CLSI)-recommended broth microdilution procedure was used to detect the efficacy of extract against d...
