Perhaps, none of the birds had not mastered this art of weaving nests, as weaverbirds. It is “weaving”, even knitting a specific pattern. Fiber, picked at random from plants, bird several times passes via the fingers into a loop and then takes the bill to the end of the “rope” and firmly tighten the loop.
These weaverbirds weave nests of males. Females only finish the interior of the house finished lining spherical “floor” soft materials and under the roof weave “ceiling” —apparently, additional protection (insulation) from the tropical sun. Each male weaves the nest for several females, and then leaves them, giving themselves to sit and feed in a cozy house offspring.

FMD is an acute viral disease of animals (mainly cattle, goats, sheep and pigs), which also hurts people . characterized by intoxication and vesicular-erosive (bubble-ulcerative) lesions of the mucous membranes of the oral and nasal cavities, and skin of the interdigital folds.
Dogs, cats, horses, chickens, ducks, geese do not get sick but can carry the virus.
The causative agent of FMD is stored in the blood and meat of infected animals, is transmitted from one animal to another by contact, through contaminated feed and manure. The pathogen persists for a long time on the health products and litter. An important source of spread of the virus is animal manure, which in such cases should be burned or subjected to biothermal disinfection.
Prevention of foot and mouth disease based on preventing the flow of FMD virus in Schmallenberg disease management and the constituent entities of the Russian Federation. The main reasons for the spread of FMD virus are: the virus introduction from dysfunctional disease entities, primarily in connection with illegal importation of animals, animal products Continue reading
This disease is called “fever dog”, although she was exposed to all mammals, including humans. Although in natural conditions are more often ill with leptospirosis of agricultural animals and rodents, “bad name” dogs was due to its extremely high susceptibility to leptospirosis.

Leptospira after aging affect the capillaries, liver, kidney, muscle, and among the possible complications of the lesion of the membranes of the eyes, paralysis, infectious-toxic shock.
The treatment of such diseases is protivoleptospirozny gamma globulin. antibiotics ( penicillin, tetracycline, aminoglycosides). In addition, doctors have to support the liver and help the patient to other drugs, depending on which organs were affected. Continue reading
