Current bacteria in milk cow breastitis – Dairy Forum – China Animal Husbandry Website – A useful animal husbandry website
A variety of microorganisms are distributed in the dairy living environment, most of the breasts is caused by Streptococcus and coliforms, and the Baitrivi Biotechnology, Henan Province, is divided into the following types of pathogens.
(1) Infectious microorganisms
1, Golden Staphylococcus aureus
Staphylococcus aureus belongs to microbacterial, Staphylococcus, is Gram-positive Socha. This belongs are distributed in feed and environment of nature and animals, and the skin mucosal of people and animals are also present. Most of them are irritated parasite, only a few local inflammatory infections caused by people and animals, and even sepsis. Can cause dairy, sheep and other animal breastitis, Staphylococcus aureus, epidermis, Porcine Staphylococcus, Intermediate Staphylococcus, Sapallococcus aureus, hemolytic Staphylococcus. Among them, Golden Staphylococcus aureus is the main pathogenic bacteria, and the rest is solidifiable enzyme negative Staphylococcus aureus, they are often in the flora.
2, Cellular Societica and Bai Parmia
There are many types of bacteria, and are widely existing in nature. It is often distributed in water, milk, dust, animal plants surface, respiratory tract, digestive tract, and urinary geduced mucous membranes. Dairy infectious breast inflammation caused by Streptococcus, as long as it is apronged bacteria, the bacteria often causes breast inflammation through squeezing or use. Brassic bacteria is generally classified into environmental cells.
mycoplasma is also known as molds, is the smallest and simplest cells that are discovered, and the only prokaryotic cells without cell walls.
(2) Environmental microorganisms
Environmental microorganisms include environmental streptococci, solidified enzyme negative Staphylococcus, Enterococcus, Escherichia coli, pneumoniae, gynecal bacillus, Salray, deformation Bacillus and Pseudompascine, etc. Usually non-commutated conditions to pathogenesis.
1. Numerous Streptococcus
Environmental Streptococcus in the breast bacteria, Puzzine Streptococcus, Buffalococci, and Dogs, and Cao Sococci, and Dogs, Clinical Fungus. Soclas, other fewer views.
2, solidified enzyme negative Staphylococcus aureus
Decozyme negative stoclasma is a class of bacteria in Staphyliopathia, composed of a variety of solidifier reaction negative Staphylococcus, there are more than 20 species, wherein epidermus , Sapoccus, Hemococcus aureus, xyloseStreptococcus, Porcine Staphylococcus, Temaisus Tunicus 6 pylospheres are related to dairy breast inflammation. They are often in the flora.
Enterococcus is circular or elliptical, in a single, double, sometimes short-chained arrangement, growth on the solid agar, spores, no spores, Gram Dye Positive.
E. coli is a bacterios, which is from 0.4 – 0.7 μm × 2 — 3 μm, or is dispersed or paired. Most strains have Zhou Sheng whip, some strains are also fragrant. In addition to a small number of strains having an A type K antigen. The two ends of the bacteria were occasionally depreciated, and Gram dyed negative.
Pathogenic Escherichia coli has bacterial hair, K antigen, endotoxin, can produce extinction, β hemolynee, vascular permeation factor, cytotoxin, neurotoxin, etc., these toxic factors have caused corresponding Pathological changes lead to animal diseases.
5, Gram-negative Enterobacter
a, Pneumoniae Clay Bacteria
Except for E. coli, Pneumoniae Clebs is the most important Gram-negative bacterium that leads to dairy breastitis. .
B, Gas Escherichia coli
Multi-chronic elapses caused by cumulatococcia and liquefied Salray.
C, Sali Bacteria
Multi-chronic elapses caused by mammics and liquefied salaria, and there is no clinical breast inflammation without specific symptoms.
D, Deformed bacteria
Shiga has bacteria, adhering to epithelial cells, causing inflammatory response. All strains have strong endotoxins, and a group of Hedger can produce an extractor that causes Vero cellopathy.
Dublin Salmonella is a bacterial, bacteria, nativea, and murine injury, bacteria, causing bulls, causing bulls, bulls, and continuous infections.
6. The Pseus
is conditional pathogenic bacteria, and its pathogenicity is associated with a large amount of internal and external toxins.
(3) Other microorganisms
can produce lethal toxins and hemolytic toxins.
BacillusPlanting in the skin and the nipple tube can cause the midness of the milk cells to increase, which can cause mild breast inflammation.
Among the branch bacterium, the biochemical properties mainly include niacin test, nitrate reduction test, catalase and urea test. The human and bovine strains produce urea enzymes. The human type can reduce nitrate, produce niacin, and the cattle can not be.
Although the breast bacillus breastfeeding is not seen, the milk cattle breast inflammation is urgent, and all cases have almost all body symptoms and breast local lesions. Obviously acute sepsis.
abortion Brucella causes cow abortion, clinical articular arthritis, breast inflammation, lymphadenitis, etc. Brucefacyscell fans caused breast inflammation, and there is no obvious naked eye change. The weight of the heavy body is high, the breast is hard, the skin temperature is increased, the pain, the milk deterioration, yellow water or flocculation, the amount of milk is reduced, even Full of breasting energy.
The source of the evangelical source of milk milk
Effectively reduce the incidence of recessive breast inflammation is more than 90%, a large reduction in the occurrence of yak diarrhea, improves milk quality.
2, enhance immune function, activate in vivo phagocytic cells, enhance their phagocytic ability, stimulate minimal immunoglobulin synthesis, promote the body’s immune response, and fully enhance animal disease resistance.
3. Reduce the occurrence of digestive tract system disease, increase dairy cows.
4, effectively promote feed nutritional digestion and absorption, improve production milk.
5, reduce the concentration of contaminated gases such as ammonia, odor, reduce environmental pollution, and improve the feeding environment.
6. Improve the health of dairy cows and improve reproductive performance.
7, microbial additive, green safety, milk safety, absolutely no resistance.
