Causes of black dolphin pneumonia

Black dolphin pneumonia can be caused by a variety of pathogens, such as Streptococcus pneumoniae, bronchial septicemic Bordetella, Klebsiella pneumoniae and so on. Among them, Bordetella bronchial septicemia is the most harmful.

Streptococcus pneumoniae is a gram-positive coccus without flagella and does not form spores. In general, people's upper respiratory tract often carries this bacteria, which is a potential source of infection. After infection, the pathogen of black dolphin can exist in the upper respiratory tract, which can be caused by the decrease of body resistance caused by stress factors such as transportation. The bacteria is transmitted by direct contact and droplets.

Bronchial septicemic Bordetella is gram-negative, Brevibacterium, non-spore and motile. Infected by direct contact or contact with contaminants and respiratory droplets. The deficiency of vitamin C in the feed of black dolphin and the decrease of body resistance can cause the mass reproduction of this bacteria and cause the disease of animals.

Klebsiella pneumoniae is a gram-negative bacilli, often in pairs or short chains. It is widely distributed in nature, such as soil, water, agricultural products and forest products, and is also common in the intestinal tract and respiratory tract of human and animals. it is a typical conditional pathogen, which often causes explosive epidemic when the resistance of animals decreases.

Black dolphin pneumonia is generally complicated with streptococcosis, which is caused by Streptococcus pneumoniae, which is a special infectious disease of black dolphin, which invades the respiratory organs and abdominal cavity of black dolphin.
