Anonymous users2024-02-06Not really, Brucella.
It is mainly transmitted through contact, and can only be transmitted from individuals carrying the disease to healthy individuals, and does not create something out of nothing. Sheep carrying Brucella are an important source of infection, but if they are not in an area where Brucella is endemic and have not been exposed to Brucella, they will not be infected.

Anonymous users2024-02-05*Not all sheep carry Brucella**. Brucellosis is a zoonotic infectious disease, and sheep, cattle, pigs and other animals can be used as storage hosts for brucella, among which sheep is the most important source of infection. However, not all sheep carry this bacterium.
If the sheep have not been exposed to brucella, they will not be infected. After sheep are infected with Brucella, they may present with symptoms such as fever, fatigue, weight loss, indigestion, and loss of appetite. However, these symptoms do not always appear, so laboratory tests are needed to determine whether an infection is present.
It is important to note that even if sheep are infected with Brucella, it does not mean that they will necessarily spread the bacteria to humans or other animals. Brucella is mainly transmitted through contact with the human body, such as through broken **, mucous membranes, digestive tract or respiratory tract, so daily precautions such as wearing masks and washing hands frequently can also effectively avoid infection.

Anonymous users2024-02-04No Brucella is a small globular rod bacteria, negative Gram staining, no flagella, no spores, generally no capsule, and virulent strains may have thin capsule. At the time of initial isolation, it was mostly globular, club-shaped and oval, and the bacteria gradually became short rod-shaped after subculture.
The Brucella cell membrane is a three-layer membrane structure, the innermost membrane is called the cytoplasmic membrane, the outer membrane is called the peripheral cytoplasmic membrane, and the outermost membrane is called the outer membrane. The outer membrane is tightly bound to the peptidoglycan (PG) layer to form the cell wall, and the outer membrane contains lipolpolysaccharide (LPS), proteins, and phospholipid layers.

Anonymous users2024-02-031. Brucellosis in sheep can be transmitted from diseased sheep to humans, but after people suffer from brucellosis, current research has not found that it spreads from person to person.
2. Brucella is divided into multiple types, one of which is "sheep type", sheep brucellosis can be transmitted from diseased sheep to humans, but the sick patient can no longer be transmitted to others, that is, it is not transmitted from person to person.
3. Although this disease is not transmitted between people, but the current scientific understanding, I personally suggest that the transmission route should also be controlled and scientifically prevented.

Anonymous users2024-02-01At present, the main source of brucellosis epidemic in China is infected sheep, and cattle, pigs and dogs are also the main reservoir hosts of brucella, but there are few cases this year. Mode of transmission: In rural pastoral areas or farmers, lambing or placental infection, secretion infection during abortion is the main one; In urban areas, the occupational exposure of fur purchasing and processing personnel is the main infection, followed by the occupational exposure of workers in slaughtering and processing enterprises. In general, household infections are only those in the process of processing raw meat; and raw milk infections are rare.

Anonymous users2024-01-30Brucella is a gram-negative aerobic bacillus. Taxonomically belonging to the genus Brucella, it is non-acid-resistant, non-spore, capsule-free, flagella-free, and club-shaped. Tissue smears or exudates are often clumped and can be seen in cells, and are often arranged in single scattered dates in culture.
Brucella can survive for 45 to 60 days in **, 40 days in Tuchongkai soil, and several weeks in milk. Weak resistance to heat, general disinfectants can quickly kill Sun Yanqi.
