Current bacteria in milk cow breastitis – Dairy Forum – China Animal Husbandry Website – A useful animal husbandry website
A variety of microorganisms were distributed in the dairy living environment. Most breasts were caused by Streptococcus and coliforms. Henan Baitri Biotechnology is now divided into the following pathogens. Class introduction.
1, Golden Staphylococcus aureus
Staphylococcus aureus belonging 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, Large Societica and Brassic Streptococcus
There are many types of bacteria, and are widely used 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, and is the smallest and simplest cells that are currently discovered, and the only prokaryotic cells without cell walls.
(2) Environmental Microorganisms
Environmental microorganisms include environmental streptococci, solidifiable enzyme negative Staphylococcus aureus, enterococcus, E. coli, pneumoniae, gynenum coli, Salia, Amorganica, and Pseudompucellococcus. Usually non-commutated conditions to pathogenesis.
1, Numerous Streptococcus
Environmental Streptococcus in milk cow breasts, Slutinus, Peartrophil, Beast Slutinus, Caucasus and Dogs, Clinical Common is mainly breast bacteria, other less common.
2, solidified enzyme negative Staphylococcus aureus
solidified enzymeStaphylococcus is a class of bacteria in Staphylococcus, composed of a variety of staphylococcus, negative staphylococcus, which is about 20, wherein epidermis, Rucominus, hemolytic Staphylococcus aureus, pigs Staphylococcus, mimic Staphylococcus aureus 6 pylospheres related to dairy breastitis. They are often in the flora.
Enterococcus is circular or elliptical, in a single, double, sometimes short-chain arrangement, growth in solid agar, no short ball shape, no Spores, Gram dye positive.
Escherichia coli is a bacterium without spore, a size of 0.4 – 0.7 μm × 2 — 3 μm, both ends are blunt, dispersed or Pair. 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 after the pathogenic infection It causes corresponding pathological changes, leading to animal diseases.
5, Gram-negative Enterobacter
A, Pneumoniae Clay Bacteria
Except for E. coli, Kleburgia in Pneumonia is caused by dairy breast inflammation The most important Gram-negative bacteria.
B, Gas Escherichia coli
Multi-chronic passage caused by bumpermia and liquefied salaria.
C, Sali Bacteria
Multi-chronic elastic passage caused by the bumpermacide caused by tarentia and liquefied Salray, or clinical breasts without specific symptoms can also occur. inflammation.
D, Deformed bacteria
Chronica is bacteria, which can adhere 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 bacterium that adapts to cattle, this bacterium and ratThe typhoid sterile bacteria contaminated the breast due to infecting cows, causing the subjungered breast inflammation and continuous infection of the cattle.
6. The Pseudomonasia
is conditional pathogenic bacteria, which is pathogenic to which the bacterium has a large amount of internal and external toxins.
(3) Other microorganisms
can result in lethal toxins and hemolytic toxins.
The bacteria can be planted within the nipple skin and the nipple, which can cause midrange mode in the number of milk cells, and can cause mild breast inflammation.
Amorganic bacterium, a large-free fermentation sugar, and the biochemical properties 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.
Multi-killing Bacillus breastfeeding is not many, but the milk cattle breast inflammation is urgent, all cases have almost all body symptoms and breasts. Local lesions, cows are obvious acute sepsis.
Abortion Brucella causes cow abortion, clinically often occurs arthritis, breast inflammation, lymphoid node inflammation, 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 gospel of milk milk
1 , Reduce the number of somatic cells, effectively reduce the incidence of recessive breast inflammation, and reduce the occurrence of yak diarrhea, improve milk quality.
2, enhance immune function, activate in vivo phagocytic cells, enhance their phagocytic ability, irritating secretion of immunoglobulin synthesis, promoting 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 and digestion and increase production milk.
5, reduce the concentration of contaminated gas such as ammonia, odor, and reduce environmental pollution, and improve the feeding environment.
6, improve the health of dairy cow, improve reproductive performance.
7, microbial additive, green safety, milk safety, absolutely no resistance.
