Ixodes ricinus (L.) (Acari Ixodidae) is a major vector for the transmission of several important human pathogens. The aim of the present study was to evaluate the in vitro efficacy of different concentrations of essential oils (Eos) on I. ricinus tick nymphs. Oils were obtained from the leaves of three plants native to Libya white wormwood (Artemisia herba alba Asso), marjoram (Origanum majorana L.) and Arâr (Juniperus phoenicea L., English common name Phoenician juniper). Assays were done using the "open filter paper method". Two concentrations from each oil, 0.5 and 1 μl/cm, were tested. The acaricidal effect was measured in terms of the lethal concentrations (LC50, LC95) and lethal time (LT50, LT95). Mortality rates were obtained by counting the surviving nymphs every 30 min for the first five hours and then at 24, 48 and 72 h. A mortality of 100% was recorded at the higher concentration of oils (1 μl/cm2) from A. herba alba and J. phoenicea at the first 2 h of exposure. Exposure to O. majorana led to 100% mortality on the third day (72 h), and this effect decreased noticeably with 0.5 μl/cm2 oil at the same exposure time. However, 50% of ticks showed a paralysis effect and less movement after 2 h. The LC50 of mortality was reached within the first 24 h of exposure time at 0.5 μl/cm2 of O. majorana, which produced 60% tick's mortality. Chemical composition of the essential oils was elucidated by gas chromatography-mass spectrometry analyses. These results suggest that essential oils deserve further investigation as components of alternative approaches for I. ricinus tick control.Prevalence, morphological and molecular characterization of Anisakid larvae in smoked herring fish (Clupea harengus) from five governorates that represent Northern, Middle, and Southern Egypt which include; Menofia, Alexandrina, Qaliubiya, Sohag, and Assiut were elucidated in this study, smoked herring fish samples were collected from local markets during 2020, 384 positive (42.7%) out of 815 examined samples, the highest prevalence was observed in middle and southern Egypt (Sohag (139/230, 60.43%), and Menofiya (123/215, 57.20%), they were found to be naturally infected with Anisakis simplex larvae as free in peritoneal cavity, Based on morphological, morphometric by SEM, and molecular analyses of ITS-2 ribosomal DNA targeted gene and phylogenic analysis, these nematodes were identified as third- stage larvae of Anisakis simplex.Zoonotic visceral leishmaniasis is caused by protozoa of the genus Leishmania. Although dogs are considered to be primary reservoir hosts of Leishmania spp., several mammals, such as foxes, jackals and small rodents may also be hosts of different Leishmania spp. Previously, cats were considered as asymptomatic hosts of the parasite without acting as a reservoir. In recent years, there has been an increasing number of leishmaniasis cases in cats, especially in regions where the infection endemically occurs. This data indicate that cats are more likely to be one of the main reservoirs of Leishmania spp. rather than being a non-reservoir host. The aim of this study is to determine the prevalence of Leishmania spp. by molecular and serological techniques among owned and stray cats in four different cities located in western part of Turkey. A total of 386 blood and 301 serum samples were collected from cats in Western Turkey where leishmaniasis is endemic. Feline serum samples were tested by IFAT to detect IgG antIn endemic regions, all animals should be protected against infection with insecticides and monitored routinely to control the spread of zoonotic visceral leishmaniasis.Theileriosis is an important tick borne disease of cattle caused by a haemoprotozoan of genus Theileria. Clinical bovine theileriosis is mainly caused by T. annulata or T. parva but the clinical disease due to T. orientalis is rare. T. orientalis mainly infect RBCs and causes "Oriental theileriosis" or Theileria-associated bovine anaemia in cattle and other livestock species. Two genotypes of T. orientalis (Chitose and Ikeda) are reported to cause severe disease in some countries. https://www.selleckchem.com/products/OSI-906.html In this report, a spontaneous outbreak of Oriental theileriosis was studied in an organized Holstein-Friesian cattle breeding farm situated in the south-eastern Himalayan ranges of Himachal Pradesh State of India. Animal blood and tick samples were tested using cytological and PCR techniques. The disease episode occurred in a protracted manner spanning over 10 to 12 months and association of T. orientalis was confirmed in 93.3% of the blood and 21.7% of Rhipicephalus microplus (tick) samples. No other tick borne pathogen was detected except Anaplasma marginale in two blood samples. Haematological profiling of infected cattle showed characteristic indicators of anaemia like haemoblobin, RBC count, haematocrit value and mean corpuscular volume at either lower than normal or near the lower normal range. The prevailing persistent anaemic changes led to more severe clinical manifestations like abortion and joint inflammation. The detected T. orientalis strains and ticks species were further confirmed by nucleotide sequence analysis of 18S rRNA and 16S rRNA genes. Phylogenetically, T. orientalis strains showed clustering with other reported strains of T. orientalis from the surrounding regions. This first report of clinical Oriental theileriosis from India emphasises the importance of T. orientalis as an emerging tick borne pathogen and role of widely prevalent ticks species in disease transmission and their impact on livestock production.Digeneans are an important class of trematodes which infect variety of animals ranging from vertebrates (mainly final hosts) to invertebrates (mainly as intermediate hosts). Additionally, some of these parasites are zoonotic and one health importance. Diversity of digeneans in Iran and reports of several zoonotic cases show the importance of these parasites in this country. This is the checklist of digenean parasites reported from Iran representing a total of 118 species, from 105 genera, 43 families, 21 subfamilies, and 3 orders that are reported from 139 species of different hosts including humans. Some of the most important final number of families, genera, and species reported in Iran fauna include Fasciolidae, Genus Fasciola, Fasciola gigantica, Fasciola hepatica, Family Dicrocoeliidae, Genus Dicrocoelium, Dicrocoelium dendriticum, Family Diplostomidae, Genus Diplostomum, Diplostomum spathaceum, Family Heterophyidae, Genus Haplorchis, Haplorchis taichui, Family Notocotylidae, Genus Notocotylu, Notocotylus aegyptiacus, Family Bucephalidae, Genus Rhipidocotyle, Rhipidocotyle illense.
