Diphtheria :- acute bacterial infection caused by Corynebacterium diphtheriaeAbhinav S
Diphtheria is an acute bacterial infection caused by *Corynebacterium diphtheriae*. It primarily affects the mucous membranes of the respiratory tract, particularly the throat and nose, but can also affect the skin. The hallmark of respiratory diphtheria is the formation of a thick, gray pseudomembrane covering the throat and tonsils, which can cause breathing difficulties and swallowing problems. Symptoms include sore throat, fever, swollen glands, and general malaise.
The bacteria produce a toxin that can lead to severe complications such as myocarditis (inflammation of the heart muscle), neuropathy, and airway obstruction. Diphtheria is highly contagious, spreading through respiratory droplets from coughing or sneezing.
Prevention is primarily through vaccination with the diphtheria toxoid, which is part of the DTP (diphtheria, tetanus, pertussis) vaccine series given in childhood. Treatment includes administration of diphtheria antitoxin to neutralize the toxin, and antibiotics (such as penicillin or erythromycin) to eradicate the bacteria.
Prompt medical attention is crucial to manage diphtheria effectively and prevent severe complications or death.
1. Tuberculosis is caused by the bacterium Mycobacterium tuberculosis and primarily affects the lungs. It was a major cause of death in the 19th century but treatable with medicines developed in the 1940s.
2. TB spreads through airborne droplets when people with active TB cough, sneeze or spit. It affects millions worldwide each year, especially in developing countries. Young children are most vulnerable.
3. Diagnosis involves tuberculosis skin testing, chest x-rays, and sputum and tissue samples. Standard treatment combines several front-line antibiotics taken for 6-12 months to kill the bacteria and prevent drug resistance.

Diphtheria spreads between humans through droplets, secretions, or direct contact. Risk factors include poor nutrition, crowded living conditions, and low vaccine coverage. The diphtheria toxin produced by C. diphtheriae is cleaved and binds to receptors on cardiac and nerve cells, causing cardiac, respiratory, and neurological damage. Diagnosis involves identifying clinical symptoms and isolating C. diphtheriae from samples using tellurite blood agar, which causes the bacteria to form black colonies. Control methods include
Vaccines are preparations of pathogens that induce immunity against diseases. They are considered a form of primary prevention and work by eliciting an active immune response. Different types of vaccines include live attenuated, killed whole organisms, and fragments of organisms. The UK immunization schedule outlines which vaccines children should receive at various ages to protect against diseases. High-risk groups like asplenic patients require additional vaccines. Vaccines are important for both individual and public health by providing direct protection and herd immunity.
Diphtheria, pertussis, and tetanus are acute infectious diseases. Diphtheria is caused by Corynebacterium diphtheriae and presents with a greyish membrane in the throat or on skin. Pertussis, also known as whooping cough, is caused by Bordetella pertussis and is characterized by paroxysmal coughing fits that can cause vomiting. Both diseases are vaccine-preventable but still occur worldwide. Treatment involves antitoxins, antibiotics, and isolation of cases. Vaccination programs have reduced rates of these diseases significantly in many countries.
Bordetella pertussis causes whooping cough. It is a highly contagious Gram-negative bacterium that infects the respiratory tract. The infection progresses through three stages including a catarrhal stage with cold-like symptoms, a paroxysmal stage with severe coughing fits, and a convalescent stage with decreasing symptoms. The bacteria adhere to host cells using adhesins like filamentous hemagglutinin and pertactin. It produces pertussis toxin and other virulence factors that damage tissues and disrupt immune function. Vaccination is effective for prevention, while antibiotics can treat the infection. Complications can be serious, especially in young infants.
This document discusses diphtheria, an infectious disease caused by the bacteria Corynebacterium diphtheriae. It produces an exotoxin that can cause local infection in the throat and airways and lead to complications affecting the heart, kidneys and nerves if the toxin spreads systemically. Clinical manifestations depend on the site of infection and may include pseudomembrane formation. Diagnosis involves culture, microscopy and toxin testing. Treatment is with antitoxin to neutralize the toxin as well as antibiotics. Active immunization with diphtheria, tetanus and pertussis vaccine (DwPT or TdaP) provides protection.
Tuberculosis is a chronic infectious disease caused by Mycobacterium tuberculosis that primarily affects the lungs. It spreads through inhaling droplets from infected individuals and can affect other organs. Young, malnourished, and immunocompromised children are most at risk. Diagnosis involves clinical features, tuberculin skin testing, chest x-rays, and microscopic examination of samples. Treatment consists of a multi-drug regimen over several months. Close contacts of active TB cases, such as young children, should receive preventive treatment to avoid infection.
Bordetella is a genus of Gram-negative bacteria that includes three human pathogens: B. pertussis, B. parapertussis, and B. bronchiseptica. B. pertussis causes pertussis (whooping cough) in humans. The bacteria are small, aerobic, non-fermentative, and fastidious. They produce several virulence factors like pertussis toxin and filamentous hemagglutinin that contribute to pathogenesis. Pertussis has an incubation period of 1-2 weeks and presents as a catarrhal stage followed by paroxysmal coughing spells characterized by a "whoop". It is highly contagious and vaccine-preventable
Tuberculosis (TB) is a bacterial infection caused by Mycobacterium tuberculosis that primarily affects the lungs. It spreads through droplets in the air from coughing or sneezing. Risk factors include HIV/AIDS, diabetes, and malnutrition. Diagnosis involves chest x-rays, sputum smear and culture tests, tuberculin skin tests, and interferon-gamma release assays. Treatment uses a combination of antibiotics over 6-9 months including isoniazid, rifampin, pyrazinamide, and ethambutol. The WHO recommends the DOTS strategy to directly observe treatment and ensure adherence and cure. Drug-resistant TB requires longer and more toxic treatment regimens.

Muktapishti is a traditional Ayurvedic preparation made from Shoditha Mukta (Purified Pearl), is believed to help regulate thyroid function and reduce symptoms of hyperthyroidism due to its cooling and balancing properties. Clinical evidence on its efficacy remains limited, necessitating further research to validate its therapeutic benefits.
One health condition that is becoming more common day by day is diabetes.
According to research conducted by the National Family Health Survey of India, diabetic cases show a projection which might increase to 10.4% by 2030.
8 Surprising Reasons To Meditate 40 Minutes A Day That Can Change Your Life.pptxHolistified Wellness
We’re talking about Vedic Meditation, a form of meditation that has been around for at least 5,000 years. Back then, the people who lived in the Indus Valley, now known as India and Pakistan, practised meditation as a fundamental part of daily life. This knowledge that has given us yoga and Ayurveda, was known as Veda, hence the name Vedic. And though there are some written records, the practice has been passed down verbally from generation to generation.

Local Advanced Lung Cancer: Artificial Intelligence, Synergetics, Complex Sys...Oleg Kshivets
Overall life span (LS) was 1671.7±1721.6 days and cumulative 5YS reached 62.4%, 10 years – 50.4%, 20 years – 44.6%. 94 LCP lived more than 5 years without cancer (LS=2958.6±1723.6 days), 22 – more than 10 years (LS=5571±1841.8 days). 67 LCP died because of LC (LS=471.9±344 days). AT significantly improved 5YS (68% vs. 53.7%) (P=0.028 by log-rank test). Cox modeling displayed that 5YS of LCP significantly depended on: N0-N12, T3-4, blood cell circuit, cell ratio factors (ratio between cancer cells-CC and blood cells subpopulations), LC cell dynamics, recalcification time, heparin tolerance, prothrombin index, protein, AT, procedure type (P=0.000-0.031). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and N0-12 (rank=1), thrombocytes/CC (rank=2), segmented neutrophils/CC (3), eosinophils/CC (4), erythrocytes/CC (5), healthy cells/CC (6), lymphocytes/CC (7), stick neutrophils/CC (8), leucocytes/CC (9), monocytes/CC (10). Correct prediction of 5YS was 100% by neural networks computing (error=0.000; area under ROC curve=1.0).
