Entomoparasitic nematodes are natural control agents for many insect pests, including fleas that transmit Yersinia pestis, a causative agent of plague, in the natural foci of this extremely dangerous zoonosis. We examined the flea samples from the Volga-Ural natural focus of plague for their infestation with nematodes. Among the six flea species feeding on different rodent hosts (Citellus pygma...

A severe outbreak of aflatoxicosis and chlamydiosis among chickens in an organised poultry farm, further super-infected by secondary microbial invasion, was investigated. Mortality was 65, 25 and 32% among broiler chicks (1-2 week of age), layer chicks (2-3 weeks of age) and broilers (8-15 weeks of age), respectively. Samples were collected from 20 representative ailing/dead birds included pool...

the diversity and richness of species are of important components to evaluate the health of ecologic system of rangelands. this research was conducted to investigate the biodiversity in riparian and neighboring areas via comparison of indices in javaherdeh rangeland of ramsar. plot-transects was randomly used to estimate diversity, richness, dominance, and evenness indices in two regions. multi...

Identifying infected laying flocks is a critical component in efforts to prevent eggborne transmission of Salmonella enteritidis to humans. In the present study, egg yolk samples from experimentally infected chickens were tested for specific antibodies with a very rapid fluorescence polarization assay using tracers prepared from the O-polysaccharides of S. enteritidis and S. typhimurium and a c...

Microorganisms of the microsporidia group are obligated intracellular protozoa that belong to the phylum Microspora; currently they are considered to be related or belong to the fungi reign. It is considered an opportunistic infection in humans, and 14 species belonging to 8 different genera have been described. Immunocompromized patients such as those infected with human immunodeficiency virus...

Malware authors apply different techniques of control flow obfuscation, in order to create new malware variants avoid detection. Existing Siamese neural network (SNN)-based detection methods fail correctly classify families when such obfuscated samples are present the training dataset, resulting high false-positive rates. To address this issue, we propose a novel task-aware few-shot-learning-ba...

Two techniques performed on skin biopsy samples (ear notches), immunohistochemistry (IHC) and antigen-capture ELISA (AgELISA), were compared for detection of bovine viral diarrhea virus (BVDV) persistent infection (PI) in 559 Angus calves between the ages of 1 and 5 months. The calves also were tested for BVDV infection using virus isolation (VI) and reverse transcription (RT)-PCR on buffy coat...

A new simple test to detect within-family clustering of infected individuals is proposed. The test is derived as the score test for several different parametric models designed to allow an increased within-family infectivity. The new test is compared with other tests proposed to detect the same type of clustering caused by increased within-family infectivity. Applications of household disease d...

is not found and the caretaker relative still refuses to cooperate, the caretaker becomes ineligible for benefits, and assistance is provided to the eligible child in tte form of protective payments, without regard to the needs of the caretaker relative. Therefore, if eligibility is determined and/or payments are made prior to the rejection of a good cause claim, it may become necessary . to re...
