Haemophilus parahaemolyticus symptoms

Once Haemophilus parahaemolyticus appears, influenza will occur, especially when the seasons change, the chances of people experiencing symptoms of this disease will increase. Then you will feel that you often have symptoms of coughing and headache, which will lead to a cold. Therefore, you must choose appropriate penicillin, cephalosporin and other drugs for treatment according to the symptoms, and it is impossible to cure it completely in the first time.

Based on the results of biochemical reactions, Haemophilus parainfluenzae can be divided into biotypes I to VIII and untypeable biotypes. The identification strips currently used in clinical practice can accurately identify the vast majority of clinically isolated Haemophilus parainfluenzae and can perform biotyping on most Haemophilus parainfluenzae.

Haemophilus parainfluenzae is a common conditional pathogen in the human respiratory tract that can cause a variety of diseases including endocarditis, nephritis, urogenital tract inflammation, biliary tract infection, peritonitis, etc. However, there is still controversy as to whether it is a pathogen of lower respiratory tract infection. In recent years, the isolation rate of Haemophilus parainfluenzae in patients with lower respiratory tract infections has been increasing year by year, and can cause lower respiratory tract infections such as pneumonia and bronchitis.

With the widespread use of broad-spectrum antibiotics, the resistance rate of Haemophilus parainfluenzae has continued to increase. The results showed that the resistance of Haemophilus parainfluenzae to various antimicrobial drugs showed an overall upward trend, with the most serious resistance to penicillin and amoxicillin (related to the production of β-lactamase), but the resistance rate to third-generation cephalosporins such as amoxicillin/clavulanate potassium, ceftriaxone, and levofloxacin was relatively low.

Haemophilus parainfluenzae (scientific name: Haemophilus parainfluenzae) is a Gram-negative bacillus that is amotile and non-spore-forming, and has various forms such as cocciform and filamentous. This bacterium is a microaerophilic bacterium with an optimal growth temperature of 35~37℃. It often resides in the respiratory tract of the body.

Vaccination with HiB conjugate vaccines is an effective preventive measure, and several types of vaccines are now widely used. In addition to prevention, treatment is mainly to treat the cause. This bacterium is sensitive to sulfonamides, penicillin, streptomycin, tetracycline, ampicillin and chloramphenicol. In the past, ampicillin was the first choice for acute infections with type b influenzae, especially meningitis and epiglottitis. Some countries have reported an increasing number of ampicillin-resistant strains year by year, so some people use chloramphenicol as the first choice.
