  Brain-Eating Amoeba  Naegleria fowleri Photo/Unsplash B rain-eating amoeba, also known as Naegleria fowleri, is a species of the genus Naegleria. It acts as both an amoeba and a flagellate, which is why this is classified as an ameboflagellate excavate. It is pathogenic to human beings. This amoeba causes fatal brain infection in humans known as amoebic meningoencephalitis (PAM) . Habitat Naegleria fowleri is mostly found in  warm freshwater hot springs rivers &lakes geothermal well water discharge from an industrial power plant water heaters minimal chlorinated swimming pools(with residual chlorine levels under 0.5 g/m³) Life Cycle of Naegleria fowleri Naegleria fowleri is a thermophilic and free-living amoeba. This amoeba basically exists in three forms. cyst stage trophozoite stage biflagellate stage  1. Cyst stage In the cyst stage, Naegleria fowleri protects itself from the harsh environmental conditions it enclosing a single cell under a single-lay...

  Shots Series: Virus Multiply(Viruses that multiply only in Plants) Article No. 1 Photo/Unsplash  V iruses are primarily classified based on their morphology, which includes the physical and chemical characteristics of their virion components as well as their genetic relationships. List of selected viruses that multiply only in plants  1. Caulimoviridae Open circular dsDNA with single-strand discontinuities, like the hepadnavirus. Molecular weight 4 to 5 × 10⁶ Iso metric 50 nm particles. It contains reverse transcriptase. Aphid vector in nature. It is included in the cauliflower mosaic virus. 2. Germniviridae Circular single-stranded DNA. Molecular weight 0.7 to 0.8 x10⁶ Germniviridae has two incomplete icosahedral particles joined as a pair. This virus is usually found in the nucleus. One to two molecules of DNA per pair of particles. It is persistent in whitefly or leafhopper vectors. 3. Luteoviridae  Single-stranded, positive-sense RNA. Molecular w...
