Lumpy Skin Disease (LSD) – A Detailed Overview 1. About Lumpy Skin Disease (LSD) Lumpy Skin Disease (LSD) is a contagious viral disease that affects cattle and buffaloes . It is caused by the Lumpy Skin Disease Virus (LSDV) , belonging to the Capripoxvirus genus in the Poxviridae family . The disease leads to severe economic losses in the livestock industry due to decreased milk production, weight loss, and trade restrictions. 2. Causes & Transmission Pathogen : Lumpy Skin Disease Virus (LSDV). Mode of Transmission : Vector-borne transmission : Spread by blood-feeding insects , such as: Flies (Stomoxys species) Mosquitoes (Aedes and Culex species) Ticks (Rhipicephalus and Amblyomma species) Direct Contact : Through infected animals. Contaminated feed, water, or equipment . Aerosol transmission (rare but possible in crowded conditions). 3. Symptoms of Lumpy Skin Disease Fever (40–41.5°C). Large firm nodules (2-5 cm in diameter) on the skin, covering the head, neck, limbs, u...

Bombay Blood Group (HH Blood Group) – A Rare Blood Type Discovery and Origin First discovered in Mumbai (Bombay), India, in 1952 by Dr. Y.M. Bhende. Extremely rare, found in 1 in a million people worldwide , but more common in India (1 in 10,000 people) due to consanguineous marriages. Unique Characteristics Individuals with this blood group lack the H antigen , which is the precursor for the A and B antigens in the ABO blood system. Contains anti-A, anti-B, and anti-H antibodies , making it incompatible with all ABO blood types. Can only receive blood from another Bombay blood group donor. Clinical Significance Blood Transfusion Challenge: People with this blood group cannot receive O, A, B, or AB blood , as even O blood contains the H antigen. Rare Donor Availability: Since the blood group is rare, finding a matching donor for transfusions is difficult. High Risk in Emergencies: Requires special blood banking and donor registration to facilitate emergency transfusions. Inherita...

Bird Flu (Avian Influenza): A Global Concern   Recent Development: A new genotype (D1.1) of Bird Flu virus has been detected in dairy cattle in the US . Previously, all detections in cattle were of genotype B3.13 . This highlights the evolving nature of the Avian Influenza virus and its ability to infect new hosts. About Bird Flu (Avian Influenza) 1. Causative Agent: Bird Flu is caused by Avian Influenza Type A virus . The virus is divided into subtypes based on two surface proteins : Hemagglutinin (HA) – Helps the virus attach to host cells. Neuraminidase (NA) – Helps the virus spread between cells. 2. Transmission and Carriers: Migratory wild birds , especially waterfowl (ducks, geese, swans), act as natural reservoirs . The virus spreads through direct contact with infected birds or contaminated environments . 3. Human Infections: Some subtypes, like H5N1, H7N9, and H5N6 , have infected humans. Transmission occurs through contact with infected birds, poultry products, or ...

Brucellosis: A Zoonotic Bacterial Disease Recent Case in India Recently, an eight-year-old girl from Kottakkal in Malappuram district of Kerala succumbed to Brucellosis , bringing attention to this zoonotic disease. What is Brucellosis? Type: Brucellosis is a bacterial infection caused by species of the Brucella genus. Common Brucella Species: Brucella melitensis (most prevalent in humans) Brucella abortus (common in cattle) Brucella suis (affects swine) Brucella canis (affects dogs) The disease primarily affects livestock but can be transmitted to humans. Transmission of Brucellosis Animal-to-Human Transmission: Direct contact with infected animals (cattle, goats, sheep, swine, and dogs). Consumption of contaminated dairy products such as unpasteurized milk and cheese. Inhalation of airborne bacteria, especially in farms, slaughterhouses, and laboratories. Human-to-Human Transmission: Extremely rare but can occur through blood transfusions, sexual contact, or breastfeeding. Symp...

Guillain-Barre Syndrome (GBS): A Rare but Serious Neurological Disorder Recent Outbreak in Pune, Maharashtra A recent outbreak of Guillain-Barre Syndrome (GBS) has been reported in Pune. The outbreak has been linked to Campylobacter , a bacterial gut infection spread through contaminated food and water. What is Guillain-Barre Syndrome (GBS)? GBS is a rare but potentially paralysing nerve disorder caused by the immune system attacking the body's nerves . It is often triggered by gastrointestinal or respiratory infections . Causes of GBS Infections : The most common cause, with Campylobacter bacteria being a primary trigger. Vaccinations or Surgery : In rare cases, some vaccines or surgeries can trigger an immune response leading to GBS. Other Viral Infections : Influenza, Zika virus, and COVID-19 have been associated with GBS cases. Symptoms of GBS Muscle Weakness : Usually starts in the legs and spreads to the upper body. Numbness or Tingling : Initial symptoms often include tingl...
