Viral infections often begin with an acute phase. Fever, fatigue and other short-term symptoms appear first. Many people recover after this stage. However, some effects continue for weeks or months. In certain cases, they are last even longer. Researchers now study these lasting outcomes more closely. Some viruses damage organs during the first infection. The […]

Bacterial Toxins: How Exotoxins and Endotoxins Cause Tissue Damage and Disease Bacteria produce toxins that harm the host. These toxins fall into two main groups: exotoxins and endotoxins. Both play a major role in tissue damage and disease. Exotoxins are proteins that living bacteria release into their surroundings. Many of them act with high specificity. […]
Clostridioides difficile infection, or CDI, is a serious cause of diarrhoea. It mainly affects people whose gut bacteria have been disturbed. Antibiotics form the strongest risk factor. These drugs kill many helpful bacteria in the intestine. As a result, C. difficile can grow and produce toxins. Broad-spectrum antibiotics such as clindamycin, fluoroquinolones, and cephalosporins carry […]
A hiatal hernia occurs when part of the stomach pushes upward through the diaphragm. The opening in the diaphragm is called the hiatus. Normally, the oesophagus passes through this opening to reach the stomach. Doctors classify hiatal hernias into four main types. Type I is the most common form. In this type, the stomach and […]
Pulmonary Pathology of Respiratory Viral Infections: Influenza, RSV, and SARS-CoV-2 Respiratory viruses commonly target the lungs. Influenza, respiratory syncytial virus (RSV), and SARS-CoV-2 cause significant pulmonary disease. Each virus produces distinct yet overlapping patterns of lung injury. Understanding these pathological changes helps explain clinical severity. Influenza primarily infects the airway epithelium. The virus damages ciliated […]
Seroprevalence and Risk Factors of Scrub Typhus, Leptospirosis, and Brucellosis in Fever Cases and Healthy Populations in Northeastern and Central India Researchers examine three important zoonotic diseases across northeastern and central India. They focus on scrub typhus, leptospirosis, and brucellosis. These infections often present as fever of unknown origin. Studies target both acute fever cases […]
