''Achatina achatina'', commonly known as the giant African snail, also known as the giant tiger land snail, and gigantocochlea, is a species of large, air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Achatinidae. The name "Achatina" is from "achates", Greek for agate. It shares the common name "giant African snail" with other species of snails such as ''Lissachatina fulica'' and ''Archachatina marginata''.

Kakum National Park
Kakum National Park, located in the coastal environs of the Central Region of Ghana, covers an area of . Established in 1931 as a reserve, it was gazetted as a national park only in 1992 after an initial survey of avifauna was conducted. The area is covered with tropical forest. The uniqueness of this park lies in the fact that it was established at the initiative of the local people and not by the State Department of wildlife who are responsible for wildlife preservation in Ghana. It is one of only 3 locations in Africa with a canopy walkway, which is long and connects seven tree tops which provides access to the forest. The most notable endangered species of fauna in the park are Diana monkey, giant bongo antelope, yellow-backed duiker and African elephant. It is also an Important Bird Area recognized by the Bird Life International with the bird area fully overlapping the park area. The bird inventory confirmed 266 species in the park, including eight species of global c ...

Molluscs Of Africa
Mollusca is the second-largest phylum of invertebrate animals after the Arthropoda, the members of which are known as molluscs or mollusks (). Around 85,000  extant species of molluscs are recognized. The number of fossil species is estimated between 60,000 and 100,000 additional species. The proportion of undescribed species is very high. Many taxa remain poorly studied. Molluscs are the largest marine phylum, comprising about 23% of all the named marine organisms. Numerous molluscs also live in freshwater and terrestrial habitats. They are highly diverse, not just in size and anatomical structure, but also in behaviour and habitat. The phylum is typically divided into 7 or 8  taxonomic classes, of which two are entirely extinct. Cephalopod molluscs, such as squid, cuttlefish, and octopuses, are among the most neurologically advanced of all invertebrates—and either the giant squid or the colossal squid is the largest known invertebrate species. The ...

Aeromonas Hydrophila
''Aeromonas hydrophila'' is a heterotrophic, Gram-negative, rod-shaped bacterium mainly found in areas with a warm climate. This bacterium can be found in fresh or brackish water. It can survive in Wikt:aerobic, aerobic and Hypoxia (environmental), anaerobic environments, and can digest materials such as gelatin and hemoglobin. ''A. hydrophila'' was isolated from humans and animals in the 1950s. It is the best known of the species of ''Aeromonas''. It is resistant to most common antibiotics and cold temperatures and is oxidase- and indole-positive. ''Aeromonas hydrophila'' also has a symbiotic relationship as gut flora inside of certain leeches, such as ''Hirudo medicinalis''. Structure ''Aeromonas hydrophila'' bacteria are Gram-negative, straight rods with rounded ends (bacilli to coccibacilli shape) usually from 0.3 to 1.0 μm in width and 1.0 to 3.0 μm in length. They can grow at temperatures as low as 4 °C. These bacteria are motile by a polar flagellum. Path ...

Ghana Snail
Ghana (; tw, Gaana, ee, Gana), officially the Republic of Ghana, is a country in West Africa. It abuts the Gulf of Guinea and the Atlantic Ocean to the south, sharing borders with Ivory Coast in the west, Burkina Faso in the north, and Togo in the east.Jackson, John G. (2001) ''Introduction to African Civilizations'', Citadel Press, p. 201, . Ghana covers an area of , spanning diverse biomes that range from coastal savannas to tropical rainforests. With nearly 31 million inhabitants (according to 2021 census), Ghana is the second-most populous country in West Africa, after Nigeria. The capital and largest city is Accra; other major cities are Kumasi, Tamale, and Sekondi-Takoradi. The first permanent state in present-day Ghana was the Bono state of the 11th century. Numerous kingdoms and empires emerged over the centuries, of which the most powerful were the Kingdom of Dagbon in the north and the Ashanti Empire in the south. Beginning in the 15th century, the Portuguese ...

Meningitis
Meningitis is acute or chronic inflammation of the protective membranes covering the brain and spinal cord, collectively called the meninges. The most common symptoms are fever, headache, and neck stiffness. Other symptoms include confusion or altered consciousness, nausea, vomiting, and an inability to tolerate light or loud noises. Young children often exhibit only nonspecific symptoms, such as irritability, drowsiness, or poor feeding. A non-blanching rash (a rash that does not fade when a glass is rolled over it) may also be present. The inflammation may be caused by infection with viruses, bacteria or other microorganisms. Non-infectious causes include malignancy (cancer), subarachnoid haemorrhage, chronic inflammatory disease (sarcoidosis) and certain drugs. Meningitis can be life-threatening because of the inflammation's proximity to the brain and spinal cord; therefore, the condition is classified as a medical emergency. A lumbar puncture, in which a needle is inserte ...

Invasive Species
An invasive species otherwise known as an alien is an introduced organism that becomes overpopulated and harms its new environment. Although most introduced species are neutral or beneficial with respect to other species, invasive species adversely affect habitats and bioregions, causing ecological, environmental, and/or economic damage. The term can also be used for native species that become harmful to their native environment after human alterations to its food webfor example the purple sea urchin (''Strongylocentrotus purpuratus'') which has decimated kelp forests along the northern California coast due to overharvesting of its natural predator, the California sea otter (''Enhydra lutris''). Since the 20th century, invasive species have become a serious economic, social, and environmental threat. Invasion of long-established ecosystems by organisms is a natural phenomenon, but human-facilitated introductions have greatly increased the rate, scale, and geographic range of ...

Quarantine
A quarantine is a restriction on the movement of people, animals and goods which is intended to prevent the spread of disease or pests. It is often used in connection to disease and illness, preventing the movement of those who may have been exposed to a communicable disease, yet do not have a confirmed medical diagnosis. It is distinct from medical isolation, in which those confirmed to be infected with a communicable disease are isolated from the healthy population. Quarantine considerations are often one aspect of border control. The concept of quarantine has been known since biblical times, and is known to have been practised through history in various places. Notable quarantines in modern history include the village of Eyam in 1665 during the bubonic plague outbreak in England; East Samoa during the 1918 flu pandemic; the Diphtheria outbreak during the 1925 serum run to Nome, the 1972 Yugoslav smallpox outbreak, the SARS pandemic, the Ebola pandemic and extensive ...
