Comparative Morphology and Life Cycle of Taenia solium and Taenia saginata: Key Differences and Similarities

Introduction: Tapeworms (Taenia solium and Taenia saginata) belong to the class Cestoda of phylum Platyhelminthes. Tapeworms are flat, parasitic animals with complex life cycles that infect animals, including humans. They are exclusively endoparasites. Comparison and contrast of Taenia solium and Taenia saginata in terms of morphology: Differences between Taenia solium and Taenia saginata: Differences in […]

Molecular Tools for Microbial Taxonomy and Phylogenetic Studies

Introduction: Some of the most powerful approaches to determine the taxonomy and phylogeny of the organisms is through the study of nucleic acids and proteins, since they are genes themselves or direct gene products that provide considerable information about the true relatedness. Phylogenetic inferences based on molecular tools characterization provide the strongest and most reliable

Novel Methods for the Laboratory Diagnosis of Helminthic Infections

Introduction: Helminthes, including Nematodes, Trematodes, and Cestodes, are associated with substantial morbidity and economic losses worldwide. Almost one-sixth of the world’s population is infected with helminthes, with an estimated 15 billion individuals, particularly in low socio-economic regions, suffering from Soil-transmitted Helminthes (STHs). Novel techniques are now being developed and tested for the diagnosis of helminthic

Bacterial Pneumonia: Etiology, Risk Factors, and Diagnosis

Introduction: Lower respiratory tract infections are the most common human infections, estimated to cause 2.74 million deaths annually. LRTIs are diverse and can present as tracheitis, bronchitis, bronchiolitis and pneumonia. Community Acquired Pneumonia (CAP) is the one that is contracted outside hospital settings. Hospital-Acquired Pneumonia (HAP) is the infection of the lungs whose evidence was

Zika Virus (ZIKV): Introduction, Transmission and Diagnosis

Introduction to Zika Virus and Vector-Borne Diseases: Emergence and re-emergence of Vector Borne Diseases (VBD) have posed a huge threat to public health worldwide. Flaviviruses like Dengue Virus (DENV), Yellow Fever Virus (YFV), and Japanese Encephalitis Virus (JEV) are already circulating globally. Since the vectors, transmission cycle, favorable climate, and epidemiology of Zika virus (ZIKV)

Autoimmunity: Introduction, Mechanisms, Examples, and Treatment

Introduction: An inappropriate response of the immune system leading to activation of self-reactive humoral or cell-mediated responses against self-antigens are called autoimmunity. Autoimmune conditions that involve direct damage to cells occur when antibodies or immune cells attach to antigens on the surface of cells. This interaction can lead to cell destruction or provoke inflammation in

Cancer Metastasis : Stages, Molecular Mechanisms, EMT in Tumor Spread

Introduction to Cancer Metastasis: Metastasis is the word for the growth of secondary cancers in an area of the body distant from the initial primary cancer. Cancer treatment is challenging because of metastases. If the treatment works in one region, there is a secondary spread in other regions. The two main causes of cancer death

Cancer and Signal Transduction: The Role of EGF Pathway in Tumor Growth and Its Regulation

Introduction to Signal Transduction and Cancer: A cell of our body depends upon the signal transduction pathway to carry out different types of cell processes at the right moment in time to basically produce physiological responses to certain types of external stimuli.  Now, even though signal transduction is very important to the functionality of our

Cell Transformation: Mechanisms, Genetic Mutations, and Cancer Progression

Introduction to Cell Transformation: The process of eukaryotic cells turning to cancerous cells from the normal cells is known as cell transformation. In cancer cell transformation there are few different modifications. In basic, there is a balance between cell growth and cell death. There are several pathways in the body that dictate the cell to

Receptor tyrosine kinases (RTKs): Introduction, Structure, Tyrosine Kinase Inhibitors (TKIs), RTKs dysregulation and cancer

Introduction: Receptor tyrosine kinases (RTKs) are plasma membrane receptor glycoprotein in nature with enzymatic activity. They are a group of 90 enzymes capable of selectively phosphorylating amino acid tyrosine residue in various substrates which leads to conformational alteration of that protein and typically activates that protein.  They are important mediators of the signaling that mediate cell
