Methodology of selection and synthesis of mathematical models of the epizootic process

Legal regulation in veterinary medicine, 2023
The epizootic process (EP) is a continuous process of the emergence and spread of explicit and latent infections of animals. In some zoonoses, the study of EP by experimental studies can have negative consequences for human health. Therefore, the development of mathematical models of EP is of great practical importance.

Processes Influencing the Duration and Decline of Epizootics in Schistocephalus solidus

Journal of Parasitology, 2011
The interplay of intermediate host fish and plerocercoids of diphyllobothriidean cestodes results in epizootics that are deceptively simple, but conceal complex biotic and abiotic interactions shaping each event independently. Although general descriptions of epizootics and some details of biotic interactions between enemies are known, much remains to ...

Ecological bases of the epizootic process of brucellosis and its control in small ruminants

IOP Conference Series: Earth and Environmental Science, 2021
Abstract The article analyzes the ecological foundations of the epizootic process of brucellosis and its control in small ruminants. Epizootic process of brucellosis in populations of small ruminants with a low level of immunity is characterized by the intensive formation of epizootic strains of brucellosis melitensis with a high level ...

Modeling of Epizootic Process in Obligate Vector-Borne Infections Transmitted by Ticks

Biology Bulletin Reviews, 2019
Abstract—An analytical review of mathematical models of the epizootic process in natural foci of obligate vector-borne infections, the causative agents of which are ecologically related to ixodic ticks and are transmitted by them, is presented. A diverse range of models has been reduced to the basic forms used to model the dynamics of the vector ...

FEATURES OF THE EPIZOOTIC PROCESS OF RABIES IN TAJIKISTAN

SCIENTIFIC SUPPORT FOR LIVESTOCK BREEDING IN SIBERIA
The epizootic situation of rabic infection in Tajikistan is characterized by annual cases of registration. The main source of distribution is dogs, wolves, foxes, sometimes small predators and rodents are involved in the epizootic chain. These animals carry out a continuous transmission cycle of the pathogen. The study of seasonal dynamics revealed the

THE EFFICIENCY OF THERAPEUTIC MEASURES FOR VARROOSIS, ACCORDING TO THE EPIZOOTIC PROCESS

Problems of veterinary sanitation, hygiene and ecology, 2022
The article discusses the efficiency of therapeutic measures for varroosis in the course of the epizootic process. Examples of therapeutic measures carried out according to the rules and in accordance with the instructions of drug manufacturers are given, both without taking into account and taking into account the course of the epizootic process ...

EPIZOOTIC PROCESS OF ECHINO-COCCOSIS AT SHEEP AND CATTLE IN TAJIKISTAN REGIONE

International bulletin of Veterinary Medicine, 2020
In different countries of the world, including the Russian Federation, echinococ- cosis has been found in many species of agricultural and wild animals. In the arti-cle are disrcibed survey facts on features of epizootic process, aspects of a natural outbreak of echinococcosis of animals in the different countries, and results of study-ing of ...

[Epizootic process caused by Salmonella species in broiler flocks].

Veterinarno-meditsinski nauki, 1986
As the result of vast epizootiologic studies for Salmonella infections in two broiler flocks the intensity of the apparent and the inapparent epizootic process was shown to grow over the period of fattening. Statistical methods, such as Shovene's criterion and the correlation analysis were made use of in the interpretation of the results.

[Epizootic process on a farm chronically infected with Aujeszky's disease].

Veterinarno-meditsinski nauki, 1977
Clinical and epizootiologic studies have been carried out in the course of one year on a farm with a permanent Aujeszkys disease infection as well as virologic and serologic investigations, performed seven times, with a total of 70 fattened pigs. No clinical symptoms of Aujeszky's disease have been established during the period of investigation, while ...

[Dynamics of a latent epizootic process as evaluated by an incidence-of-infection index].

Veterinarno-meditsinski nauki, 1984
The index of infection (the number of positive samples to the total number of investigated samples ratio) was used to study the intensity of the inapparent epizootic process in avian salmonellosis. Two flocks of broiler birds were followed up for the presence of Salmonella organisms over the period of hatching up to the end of fattening.
