in dogs is acute kontagiozna viral disease, manifested by a complex set
of simpatomi under which the fore stand fever, catarrhal-inflammatory
processes of mucosa, skin exanthema and nerve disorders. Etiology Classification of the causative Virus family Paramyxoviridae, containing RNA. In terms similar to the antigenic agent of influenza type A, measles and poliomyelitis in man and infectious laringotraheit rinderpest Resistance to physical and chemical factors Temperature: In the frozen remains very long (in dried tissue - for 4 months at a temperature of -10 to -14 ° C - one year and lyophilized at -24 ° C - 5 years). Disinfectants: Ordinary disinfectants (2% sodium hydroxide, 5% formalin and cresol preparations or chlorine and 20% lime-ovo limewater) ruined it for a short time. Survival: Stability under conditions of decay is negligible. Epidemiology Host Susceptible are almost all members of the order Carnivora (dog, fox, wolf, jackal, dingo, coyote, weasel, badger, otter, mink, panda, etc.).. Most often ill young animals, but are not excluded disease in all ages. The greater incidence of age from 2 months to 1 year due to the fact that most of the older dogs have had overt or covert form of infection, and the infants acquire temporary passive immunity through antibodies contained in colostrum and milk the mother. Can be experimentally infected hamsters, and animals of the cat family and rodents are susceptible. Weasel exhibits a strong susceptibility to disease and died after artificial infection, but virus passage several times during the weasels, lost virulence for kucheta.Tova indicates that the virulence of the virus is too fluid. Transmission Infection is usually realized by alimentaren (per os) and aerogenen pat.Dopuska that often nosoglatkata and tonsils are the front door of the infection Direct contact between animals - much more difficult Hematophagous insects and animals can also carry disease Seasonal variations: should the breeding season in dogs Sources of virus All secretions and excretions of incubation (end of incubation period), patients preboleduvali animals (months after the rescue). Diagnosis Incubation period is 3-10 days. Clinical diagnosis Acute form Sudden increase in body temperature (40-41 ° C) with deterioration of general condition: fatigue, omarlushenost, loss of appetite, momentary twitching of the body After about two days of the manifestation of the first signs symptoms reflects in two phases: viremic and complicated During the viremic phase of the background of major depression, tears, vomiting, diarrhea and skin eruption dynamics are reflected in the following specific symptoms: conjunctivitis and rhinitis catarrhal to expire at the beginning, passing gradually into foamy yeast. Conjunctivitis may be complicated by keratitis, corneal ulcers and even complications leading to blindness. Ocular discharges can cause loss of hair in the area and podochnata krustozno inflammation of the eyelids to their full pritvaryane. Complicated phase can be divided into several types: intestinal, pneumonic, entsefaliten. Intestinal type: acute or subacute gastroenteritis with watery light stools, often mixed with blood. Pneumonic type: dry cough, as if stuck in the bone glatkata.Sled end of the first week can be found bronchopneumonia. Entsefaliten type: epileptic seizures, spasms of the masticatory muscles, uncoordinated movements, impairment of consciousness or involuntary defecation. Perakutna form Sudden onset of high fever (denial of food, severe depression, spasms) for 2-3 days and ends with death. Subacute and chronic forms Edema of the tonsils, the adenine of the cervical lymph nodes, persistent cough leak from eyes with frequent symptomatic photophobia, myocarditis Development for 15-20 days without significant symptoms Pnevmopatiya Lesions Emaciation, conjunctivitis, rhinitis In perakutnata form - exudate in the pericardial sac, bleeding under the epicardium, catarrhal inflammation (redness and swelling) of the mucosal In the acute form is purulent-catarrhal inflammation of upper respiratory tract and bronchi, sometimes bronchopneumonia and pleurisy serofibrinozen catarrhal inflammation and bleeding in the stomach and intestines Overall, it can be said that no specific pathological changes Differential diagnosis Rabies Aujeszky's disease Infectious hepatitis Leptospirosis Toxoplasmosis Salmonellosis Corona-and rotavirus enteritis Non-infectious encephalomyelitis Epilepsy Laboratory diagnosis Indirect fluorescence microscopy Precipitation reaction in agar gel Microscopic demonstration of Lenz's cells in preparations of the nasal mucosa, tonsils or ocular conjunctiva Virusneutralizatsiya Fixation of complement Treatment Specific treatment - serum gamma globulin Non-specific tools - broad spectrum antibiotics, polivitaminni preparations dehydrated funds heart equipment, antipyretic agents, anti-money, sedatives, etc.. Prevention and Control Medical prophylaxis Using hyperimmune sera is limited due to their short term effect and high cost Different vaccines are well tolerated by the animals and build a stable and prolonged immunity |
