With years of devoted research experience in the pathogen sector, Amerigo Scientific is glad to introduce a wide range of antibody products designed for critical aspects of infectious disease research. Our products stand out for their exceptional sensitivity and specificity, which guarantee reliable detection of crucial targets linked to infectious diseases.
Microorganisms, a diverse group of minuscule and simple organisms existing in nature, are only discernible through the use of light or electron microscopes due to their small size. Among them, pathogenic microorganisms, also known as pathogens, can infiltrate the human body and instigate infectious diseases, mainly including bacteria, viruses, fungi, and parasites. Pathogens proliferate and release harmful substances within the host, leading to various pathological changes and resultant infections. Simultaneously, these invaders trigger immune responses within the human body, prompting the production of antibodies to combat them.
Bacteria are simple-structured, unicellular creatures that are abundant, varied, and extensively found in nature. Certain bacteria, known as pathogenic bacteria, can infiltrate the human body and cause diseases. These pathogenic bacteria, like Clostridium botulinum, Helicobacter pylori, and Staphylococcus aureus, possess virulence factors such as invasiveness and toxins. Invasiveness allows bacteria to breach the body's defenses, multiply, and spread within the body. The main components of invasiveness include invasive enzymes, capsules, and other substances on surface structures. Bacterial toxins are categorized as endotoxins and exotoxins. Endotoxins are lipopolysaccharides found in the cell wall of Gram-negative bacteria. They are released when the bacteria die and are harmful to both humans and animals. Exotoxins are protein substances produced by live pathogenic bacteria. They are highly toxic and target specific tissues and organs in the body. Depending on the site of infection, pathogenic bacteria can lead to inflammation in various organs and increase the risk of cancer.
Viruses are non-cellular creatures that replicate in living cells to parasitize and multiply. They only contain one nucleic acid, either DNA or RNA. Viruses release their genetic components into host cells, whereupon they take over the replication process, ultimately causing the death of the host cell and releasing more viruses. This cycle of infection can cause a variety of symptoms and lead to infectious diseases. For instance, coronavirus leads to respiratory diseases, human immunodeficiency virus (HIV) infection causes acquired immune deficiency syndrome (AIDS), rabies viruses result in fatal rabies, and herpesviruses cause herpes zoster, herpes genitalis, and herpes orofacialis.
Fungi, classified as neither plants nor animals, are eukaryotic organisms that produce spores and lack chloroplasts. They encompass molds, yeasts, and mushroom fungi. While the majority of fungi are harmless, approximately 300 species are identified as pathogenic to humans. The pathogenic fungi are mainly molds, while others such as Cryptococcus neoformans and mushroom fungi can also cause infections in humans. Fungal infections are divided into opportunistic and primary categories. Opportunistic fungal infections are most commonly observed in individuals with compromised immune systems, frequently leading to fatality. Typical examples include aspergillosis, trichinellosis, and candidiasis. Primary fungal infections typically occur when fungal spores are inhaled, manifesting as a slow-onset disease that can progress to pneumonia in the lungs.
Parasites are lower eukaryotic organisms that parasitize other organisms in or on their bodies to obtain nutrients. Parasites that cause infections can be categorized into three main groups: protozoa, helminths, and ectoparasites. Protozoa such as Plasmodium, Leishmania, and Trypanosoma can cause serious diseases in humans, with malaria being one of the most deadly. Helminths, also known as intestinal parasites, include hookworms, roundworms, and whipworms, which can cause gastrointestinal infections. Ectoparasites, such as mites, sucking louse, and fleas, can work not only as pathogens but also as vectors to transmit disease. Most parasitic infections are more common in tropical and subtropical regions. Intestinal parasites are usually associated with areas with inadequate sanitation.
