Treatment for Haemophilus influenzae

Haemophilus influenzae

The first step to denial against Haemophilus influenzae infection is giving antibiotics. For the people with only less infection can be given treatment by using oral antibiotics just for 10 – 14 days and they don’t require hospitalisation. For mild contagion the recommended antibiotics are azithromycin, amoxicillin-clavulanate, sulfamethoxazole or trimethoprim and cefuroxim.

Ampicillin and amoxicillin must be applied only if the lab tests confirm their potency. For high infection of Haemophilus influenzae like infection in lungs, brain, bloodstream and bone need endovenous administration of 3rd generation ceftriaxone, cephalosporins and ciprofloxacin or cefotaxime for 10 -14 days. The most common side effects by using these antibiotics include vomiting, nausea, and diarrhea. TMP/SMX can cause the rare condition recognized as Stevens-Johnson syndrome, it is characterized by purplish or red skin rash that disperses and blisters, eventually inducing the sinks’ top layer to die.

The use of cephalosporins and fluoroquinolone in compounding with macrolides like erythromycin, or azithromycin are also useful for treating respiratory tract contagion caused by Haemophilus Influenzae. To re-vaccinated individuals oral rifampin of low dosages are prescribed for those who have been exhibited to Haemophilus Influenzae to preclude contagion. Rifampin can raise the metabolic process of oral contraceptives, still and can make tears and urine red or orange and hence, must be used with precaution. Oxygen therapy is frequently given to patients who are having Haemophilus influenzae infections in lungs and bloodstream that induce shortness of breath plus disorientation. These kinds of patients are generally hospitalized. They are given oxygen using a nasal cannula or a simple face mask with concentration higher than the room environment.

Prevention for Haemophilus Influenzae


Some special Conditions and Prevention tilts for Haemophilus influenzae infection maintains decent respiratory function via proper positioning and humidification for children when necessary, and suctioning when needed. Observe for signs of dyspnea and cyanosis, which necessitate a tracheotomy or intubation. Check the patient's record to conform that they don’t have drug allergies, before giving antibiotics. We should monitor intake which includes I.V. infusions and also output. Observe for symptoms of dehydration, like parched lips, decreased skin turgor, decreased urine output, concentrated urine, and increased heart beat. Watch the rate and kind of respirations. For home treatment, advise that the patient live in room humidifier or take a breather moist air from shower or bath, when necessary. Observe the whole blood count for marks of bone marrow impression when therapy admits chloramphenicol. Take preventive measures, like giving the Haemophilus influenzae vaccine to kids of age 2 years or less than that, maintaining respiratory isolation, applying right hand-washing technique, decently discarding of respiratory secemments, and decontaminating all instruments.

The Treatment for Haemophilus influenzae infection generally responds to a two-week treatment of ampicillin, after giving this treatment also 30% of bacteria are not destroyed. Ceftriaxone, chloramphenicol or cefotaxime is used at the same time until bacteria shows sensitivity. Rifampin should be provided before discharge to ensure treatment success. These diseases are cured with antibiotics. Mostly the antibiotics are provided in tablet form or liquid form. The Haemophilus influenzae vaccine can prevent most serious cases of H flu disease.

Hemophilus Influenzae - Overview of Hemophilus Influenzae

Hemophilus Influenzae

Hemophilus Influenzae is a gram negative, non motile bacillus. It has fastidious growth requirements. It requires enriched media such as blood agar or chocolate agar for their growth because accessory growth factors known as factor X and V present in blood are essential for their growth. Optimum temperature for their growth is 35-37 degree. Antigenic structure consists of 3 major surface antigens capsular polysaccharide, outer membrane protein, lipo polysaccharide. Type b polysaccharide has a unique chemical structure containing polyribosyl ribitol phosphate which induces IgG, IgM, IgA antibodies which are bactericidal, opsonic & protective. Virulence factors are capsular polysaccharide which resist phagocytosis, pili which helps in the attachment of organism to epithelial cells, outer membrane proteins which contribute to adhesion and invasion of host tissues, IgA1 protease that specifically cleaves the heavy chain of IgA1. They are commensal in the nasopharynx or oropharynx.

Infections caused by Haemophilus influenzae B are Meningitis, Acute epiglottitis, Pneumonia, Bronchitis& Suppurative lesions. H.influenzae is killed by heat 55 degree C for 30mins, refrigeration at 4 degree C, disinfectants& drying. The specimens to be collected for laboratory diagnosis are CSF, Blood, Throat swab, Sputum, Pus, aspirates from joints, middle ear, sinuses etc. These specimens can be sent for direct microscopy such as Gram staining, Immunofluorescence and quelling reaction, CIE or it can be sent for Culture. It can be treated by using Sulphonamides, Chlorampnenicol, Cefotaxime, ceftazidime. But Amoxycillin-clavunate or Clarithromycin is more effective. Prophylaxis is purified type b polysaccharide vaccine used in children, Haemophilus influenzae B PRP vaccine used in young children.

Hemophilus Influenzae - Mortality and Morbidity of Hib

Hemophilus InfluenzaeActually the death rate of Haemophilus influenzae B meningitis is nearly 5%. But the rate people affected by this disease are very high when compared to death rate. Neurological alters are included in this disease, which occurred in about 50% of the people and the changes includes hearing loss, language delay , developmental delay, seizures, language disorders, ataxia, behavioral abnormalities, mental retardation, impaired vision, motor problems, and hydrocephalus. Nearly 6% of the people are affected by permanent hearing loss i.e. even by treatment also it won’t be cured. The death rate for epiglottitis is about 5 to 10% due to obstruction of respiratory tract. The Neonatal Haemophilus influenzae B disease has the death rate of 55%.

From the year 1980 i.e. the prevaccine era to the year 2005 i.e. vaccine era the invention of vaccine-preventable has reduced the disease and also the mortality rate. Licensing of Haemophilus influenzae B conjugate vaccine resulted to a substantial fall of Haemophilus influenzae B disease in United States. The mortality and morbidity rate of Hib disease remains very high in any parts of universe where the vaccine is not used. In the year 2006, Active Bacterial Core Surveillance Report figured that, in the USA, 4800 cases of trespassing Haemophilus influenzae B transmission occurred, which results in 700 deaths. Bacteremia and trespassing disease related with NTHi are turning more dominant and carry a substantial mortality rate. There is no sexual predilection in Haemophilus influenzae B disease, but women are in danger for tuboovarian abscess, postpartum sepsis and chronic salpingitis affected by NTHi which colonize the venereal tract.

Symptoms of Haemophilus Influenzae

Haemophilus Influenzae - Symptoms of Haemophilus Influenzae

The Symptoms of Haemophilus Influenza are unusual irritability, fever, loss of balance, photophobia, swelling and redness, burning of eyes, ear pain, hearing difficulties, fluid running out from ear, pulling or pushing at one ear or both, staying asleep or difficulty in sleeping, vomiting and nausea, liquid run out from one eye or both

The Signs and Symptoms of Haemophilus Influenzae Infection are: Haemophilus Influenza elicits a characteristic tissue reaction which is an acute supportive inflammation. When the larynx, bronchial tree and trachea are affected by H. influenzae it leads to 10 mucosal dropsy and thick transude; when it occupies the lungs, it results to broncho­pneumonia. In pharynx, Haemophilus Influenza generally develops no remarkable alters, except when it affects epiglottitis, which usually affects both the pharyngeal and the laryngeal surfaces. Pharyngeal mucosa possibly rarely, reddened with soft yellow transude. More commonly, it looks normal or shows' just slight imbue redness, even when severe pain causes swallowing difficult or not possible. These infections typically affect high fever and extrapolated malaise.

The Haemophilus Influenza B bacterium lives in the throat and nose and can do so but it will not cause any malady. It is problem merely when the bacterium occupies the body's defenses that malady results. Generally other elements, such as create opportunities for Haemophilus Influenza B, or suppressed immune system. Meningitis is the most usual disease ensuing from Haemophilus Influenza B bacterium. The symptoms include vomiting, fever, joint stiffness and weakness. It may also cause malady in other parts including the throat, lungs, blood and bones.

Spreading of Haemophilus Influenzae type b



Haemophilus influenzae B disease is affected by Haemophilus influenzae which is a serotype b, which is a bacterium. Because of the use of powerful vaccines against this Hib disease, very fewer cases are diagnosed now. Haemophilus influenzae B disease is affected via contact with discharges, throat of an affected person or droplets from nose. Haemophilus influenzae B can be treated properly with antibiotics. We can prevent Haemophilus influenzae B disease by giving the vaccine at the age of 2.

Haemophilus influenzae B disease is scatter through contact with droplets or discharges from the nose, throat of an affected individual. Haemophilus influenzae B disease can spread out from one person to another person via coughing, sneezing, or speaking nearly with an affected person. The most mutual and severe expression of Haemophilus influenzae B infection is meningitis i.e. inflammation and swelling up in the coatings of the spinal cord and brain. The children’s immune system are not developed in a full-fledged manner H. flu bacteria mainly cause infections in broods.

Particularly most of the kids get infected in the cavity of the nose and the ears. H. flu bacteria are extended through tainted droplets secretions of the respiratory from a single person to another. It is always safe to use mask, kerchief and gloves to avoid infection. Keeping ourselves clean and having a proper hand wash would definitely fight with the bacterium. Its symptoms may include lethargy, fever, a stiff neck and vomiting. If Haemophilus influenzae B meningitis comes, death happens in 1 out of 20 kids and permanent brain harm in 10 to 30 % of the survivors.

Haemophilus influenza - How does it spreads?



Haemophilus influenzae is a causative factor for certain cases of chronic and meningitis pulmonary disease. Haemophilus influenzae can induce contagion in the respiratory pathway, which can spread out to other organs.

  • Infection is spread via sneezing, touching, or coughing.

  • The bacteria can induce sinusitis, middle ear contagions, and more serious transmission, including epiglottitis and meningitis.

  • The diagnosis is confirmed by discovering the bacterium in a sample which is selected from infected tissue.

  • Children are regularly given a vaccine which effectively prevents contagion because of Haemophilus influenzae type b.

Haemophilus influenzae B disease may be transferred via contact with mucus secretion or throat of an affected person and droplets from the olfactory organ. Its symptoms may include lethargy, fever, a stiff neck and vomiting. Other symptoms depend on the portion of the body infected. The incubation period of time for Haemophilus b disease is unknown; merely it is belike less than 1 week. If Haemophilus influenzae B meningitis comes, death happens in 1 out of 20 kids and permanent brain harm in 10 to 30 % of the survivors.

Many forms of Haemophilus normally live in the upper respiratory tract of children and grownups and rarely induce disease. One species induce chancroid, which is sexually transmitted disease. While other species induce endocarditic i.e. contagion of heart valves and rarely, abscesses i.e. collections of pus in the lungs, brain, and liver. Some strains cause contagion of tympanic cavity in children, lungs in adult, and the sinuses in adult and children, especially those with COPD or AIDS.
