Mycoplasmosis and ureaplasmosis
Mycoplasmas – the smallest free-living microorganisms (prokaryotes), belong to the family of Musplasmataceae, which is part of the Mycoplasmatales class of the Mollicutes class. Mycoplasmas are extremely polymorphic microorganisms. In smears prepared from organs and cultures, round, ring-shaped, oval, cocciform and filiform formations are found. Cells have a different size, which according to various authors, ranges from 125 to 600 nm. The features of mycoplasmas that are unique to prokaryotes are: the absence of the cell wall and its precursors (which biophysically brings them closer to the L-forms of bacteria). Instead of the cell wall, they have a three-layer membrane, a cytoplasm with a nuclear substance, granules and vacuoles. The membrane consists of polar lipids and proteins. The average cell Continue reading
Labrador Heart
When the dogs “go to heaven, new stars light up there …” I want to believe this after the pilot and poet Exupery, so that, looking into the bottomless night space, I remember the good that “our little brothers” gave us.
Somewhere, behind the constellation of the Hounds of the Dogs, there is probably the constellation of Labradors … I think so when I remember the chocolate Mona, which appeared in our house ten years ago, with a small fluffy lump and cheerful eyes, a wide velvet forehead, with satin pillows on thick strong legs and a bare pink belly.
Then I did not know how much my life would change, as I did not expect that this chocolate Mona – Mellani would eventually become the Queen – the mother of a large family of Labradors in the nursery Ans Lumens, “The Existing Light” (translated from Latin in interpretation – Divine Being), which gave true friends and even Champions to many lovers and connoisseurs of these noble animals.
And when – years later – Mona will leave – she will light up with a small star in the very constellation of Labradors that is Continue reading
Nursery blindness
This fact applies to inbreeding, and to double litters, and in general to breeding ……
One of the greatest tragedies that befell a dog breeder is the so-called “nursery blindness.” This term means that the dog breeder does not see the flaws in the dogs he breeds, but he can very well see the flaws of the livestock of other kennels. There is, however, another, perhaps even greater, flaw in dog breeders, the so-called “breed blindness”. This happens when a flaw has not only crept in, but has already taken root in the breed, and experts in the ring miss it, since there are very few dogs without such a flaw. In the end, the flaw becomes accepted for the breed. Continue reading
