Models to assess the risk of introduction of selected animal viral diseases through the importation of live animals as a key part of risk analysis
2021
Gierak Anna | Śmietanka Krzysztof
Introduction of an animal viral disease, especially a notifiable disease, into an importing country or region free from the disease may lead to serious epidemiological consequences and economic losses. Trade in live animals is historically considered one of the most important risk pathways. To estimate the magnitude of such risk, the likelihood of a virus’ entry into a country and the consequences of this event should be jointly evaluated. Depending on data availability, the urgency of the problem and the detail level of the objectives, a risk assessment may be conducted in a qualitative, semi-quantitative or quantitative way. The purpose of this review was firstly to provide a brief description of each step of the risk analysis process, with particular emphasis on the risk assessment component, and subsequently to supply examples of different approaches to the assessment of the risk of the introduction of selected animal viral diseases. Based on the reviewed models, the overall likelihood of introduction of particular diseases was generally estimated as low. The output risk value was strongly dependent on the duration of the silent phase of the epidemic in the country of origin. Other parameters with some bearing upon the risk derived from the epidemiological situation in the country of origin and the biosecurity or mitigation measures implemented in the country of destination. The investigated models are universal tools for conducting assessment of the risk of introduction of various animal diseases to any country. Their application may lead to timely implementation of appropriate measures for the prevention of the spread of a disease to another country or region.

2020
Sabri Abdul Rahman Mohammad | Khairani Bejo Siti | Zakaria Zunita | Hassan Latiffah | Azri Roslan Mohd
Leptospirosis is a bacterial disease that affects both humans and animals, the occurrence of which increases markedly during and after heavy rainfall and flooding. The aim of this study was to determine the serological prevalence of leptospiral infection in livestock after a voluminous flood in 10 districts of the Malaysian state of Kelantan.

2016
Płonek Marta | Wrzosek Marcin | Nicpoń Józef
There are numerous biomarkers of central and peripheral nervous system damage described in human and veterinary medicine. Many of these are already used as tools in the diagnosis of human neurological disorders, and many are investigated in regard to their use in small and large animal veterinary medicine. The following review presents the current knowledge about the application of cell-type (glial fibrillary acidic protein, neurofilament subunit NF-H, myelin basic protein) and central nervous system specific proteins (S100B, neuron specific enolase, tau protein, alpha II spectrin, ubiquitin carboxy-terminal hydrolase L1, creatine kinase BB) present in the cerebrospinal fluid and/or serum of animals in the diagnosis of central or peripheral nervous system damage in veterinary medicine.

2010
F. A. Khalafalla | Fatma H. M. Ali | K. A. Abd-Allah
A total of two hundreds of slaughtered animals; 50 each of cattle buffaloes, sheep and buffalo calves were collected from slaughterhouse Giza. Each animal was represented by muscular part, prenephric fat, liver, and kidneys. The Four Plate Technique (FPT) is intended to detect antimicrobial residues in collected samples. The liver samples showed high detection incidences (30, 16, 16 and 8%) in cattle, buffaloe, sheep and buffaloe calves respectively as compared to kidney samples (16, 12, 10 and 6% respectively). The lowest incidence was detected in fat samples (0%) followed by muscle samples (4%). High incidence was detected in medium I followed by medium II and III, finally medium IV as well as medium V which failed to be showed any incidence of detection. The tetracycline residues in tissues of slaughtered animals depend on husbandry as well as on withdrawal time after use. The liver (67 + 15, 50 + 14, 54 + 10 and 3 +0.8) and kidney (63 + 16, 46 + 12, 56 + 12 and 8 + 2) samples in cattle, buffaloe, sheep and buffaloe calves respectively showed high residual levels as compared with muscles and fat. The detection of sulfonamide residues in tissues of slaughtered animals may be attributed to misuse of these compounds for long term in animal feed as well as result in accumulation in animal tissues.

2012
Ahmed A. ElGhali | Shawgi M. Hassan
In this review, we collate information about ticks identified in different parts of the Sudan and South Sudan since 1956 in order to identify gaps in tick prevalence and create a map of tick distribution. This will avail basic data for further research on ticks and policies for the control of tick-borne diseases. In this review, we discuss the situation in the Republic of South Sudan as well as Sudan. For this purpose we have divided Sudan into four regions, namely northern Sudan (Northern and River Nile states), central Sudan (Khartoum, Gazera, White Nile, Blue Nile and Sennar states), western Sudan (North and South Kordofan and North, South and West Darfour states) and eastern Sudan (Red Sea, Kassala and Gadarif states).

Objective: The objective of this study was to investigate the efficacy of newly developed multi¬component ear drops for the treatment of otitis caused by parasites, bacteria, and fungi in dogs, cats, ferrets, fancy rabbits, and foxes. Materials and Methods: A new drug for veterinary use was developed that contained levofloxacin hemihydrate (0.3%), clotrimazole (0.1%), dexamethasone sodium phosphate (0.1%), and mox¬idectin (0.01%). In the initial stage of otoacariasis (or the ear form of psoroptic scab), the drug was used twice with an interval of 57 days. When otoacariasis (psoroptic scab) was complicated by otitis of bacterial and/or fungal etiology, the drug was used as follows: instilled once a day, within 1014 days in the ear canal for 25 drops of the drug. The study of therapeutic efficacy was per¬formed on cats, dogs, ferrets, foxes, and fancy rabbits with ear pathology. Results: The recovery of cats, ferrets, dogs, and foxes after the double use of ear drops during otoacariasis was established. In the ear form of psoroptic scab in fancy rabbits after treatment, Psoroptes cuniculi mites were not detected. The specific (antimicrobial and antifungal) activity of the drug was confirmed in vivo using the following scheme of drug use: the drug was instilled once a day, within 1014 days in the ear canal, 25 drops of the drug in animals with external otitis and otitis media. Conclusion: The rational combination of active components developed in this study is effective and safe for use in animals with microbial diseases of the ears.
