What is stomatitis?
Stomatitis is an inflammation of the mucous membranes of the mouth, in English literature it is often called “mouthrot” is a rotting mouth. The process can be local or generalized, acute or chronic.
Causes of stomatitis in snakes.
Stomatitis is not a primary disease develops on the background of immunosuppression caused by:
– hypothermia and stress condition of the animal;
– hypovitaminosis, due to depleted, proper nutrition (especially a lack of vitamin C, next);
– other diseases, against which decreases the immunity of the animal.
Often the disease starts with mechanical injuries of the mouth (the snake strikes his head on the glass when shooting, the damage caused by feeding rodents, etc.).
The signs, which can determine the presence of the disease.
– early in the disease oral mucosa is pale, with a slight bluish tint, with some light swelling;
– on the mucosal surface can be seen a small amount of discharge that resembles thick saliva. Further discharge will become purulent (pus in reptiles often has the appearance of cottage cheese with a slight yellowish tinge, in advanced stages – blood).
focal disease often spreads in the submucosal layer between the gum and the skin Continue reading
In the Atlantic ocean situated island called Queimado Grande or whatever it is called ” snake. It is located near district of são Paulo, located in Brazil. The territory of the island is small, and employs approximately 0,43 km 2. and its height is about 200 meters. People Queimado-Grandi sidestep, and local authorities imposed a ban on visit this site
Bonito is a beautiful place of Brazil
Here is found the most dangerous snake on the planet that is called island bothrops. Her wounds are very afraid, through the fact that it immediately causes death of the tissue. Reliable evidence of a bite bothrops island is extremely small, but judging by the chemical composition of the snake’s venom is 5 times more dangerous than their mainland brethren. For example, in Costa Rica due to the biting of the dies cacahuete bothrops at least 6 people. The snake’s venom causes the victim the destruction of red blood cells and blood vessels, the site of the bite swells, possible bleeding of the internal organs. Without the antitoxin, the poor guy has very little chance of survival.
This place is untouched by humanity. Here is beautiful scenery that is filled with beautiful Continue reading
Found a gene that determines, will become a gamete sperm or egg
Japanese genetics found in the DNA of fish unusual gene that determines it, will the sex cell sperm or egg, and changed his work so that in the ovaries of female fish began to form spermatozoa and in the testes of males of the egg, according to a paper published in the journal Science .
“We knew that gametes can turn into sperm and ovum, but no one has suggested that these cells in the vertebrate animals have a special gene”switch” that determines their fate – to become a sperm or egg. Our results indicate that the cell is able to go all the way. This is a very important and unexpected discovery” – quoted by RIA “Novosti” scientist Minoru Tanaka from the Institute of General biology of Japan in the city of Okazaki.
Tanaka and his colleagues made this unusual discovery, watching the development of germ cells in testes and ovaries rice fish-oriii (Oryzias latipes). During maturation of sperm and egg cells, researchers monitored changes in the level of activity of different genes, trying to find the differences between future male and female reproductive cells.
The attention of scientists was attracted to gene foxl3 – “archival copy” of the gene foxl2, which is responsible for growth of eggs and maintaining Continue reading
