Hedgehog Flea
The hedgehog flea (''Archaeopsylla erinacei'') is a flea species which, as indicated by its common name, is an external parasite specifically adapted to living with the European hedgehog and the North African hedgehog, but it has also been found on other animals. It is the only member of the genus ''Archaeopsylla''. Description Named in 1835 by Peter Friedrich Bouché, ''A. erinacei'' is a common flea "found on every hedgehog, usually in large numbers". A typical number of fleas on a hedgehog is about a hundred, but up to a thousand have been reported on sick animals. The flea is occasionally found also on dogs and cats, but only temporarily, and has been known to cause allergic dermatitis in dogs. It has also been found on foxes. The flea's length is between 2 and 3.5 millimetres, and its food is the blood of the host. Reproduction The flea's reproductive cycle is closely connected with that of the host species. The female breeds only in the nest of a breeding hedgehog, and this ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Animal
Animals are multicellular, eukaryotic organisms in the Biology, biological Kingdom (biology), kingdom Animalia (). With few exceptions, animals heterotroph, consume organic material, Cellular respiration#Aerobic respiration, breathe oxygen, have myocytes and are motility, able to move, can reproduce sexually, and grow from a hollow sphere of Cell (biology), cells, the blastula, during embryonic development. Animals form a clade, meaning that they arose from a single common ancestor. Over 1.5 million extant taxon, living animal species have been species description, described, of which around 1.05 million are insects, over 85,000 are molluscs, and around 65,000 are vertebrates. It has been estimated there are as many as 7.77 million animal species on Earth. Animal body lengths range from to . They have complex ecologies and biological interaction, interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as ...

Spilopsyllus Cuniculi
''Spilopsyllus cuniculi'', the rabbit flea, is a species of flea in the Family (biology), family Pulicidae. It is an external Parasitism, parasite of rabbits and hares and is occasionally found on cats and dogs and also certain seabirds that nest in burrows. It can act as a Vector (epidemiology), vector for the virus that causes the rabbit disease myxomatosis. Description The rabbit flea is about long and a dark brown colour. It is laterally compressed, has three pairs of legs and no wings. Its head is held at an angle to its body and its mouthparts are adapted for piercing the skin of its host and sucking its blood. It has a pronotal comb or row of spines just behind the head and a genal comb of spines below the head and these help to distinguish it from other species of flea. It is a sedentary flea that stays feeds of a single location for a long period of time. ''S. cuniculi'' have adapted to feed on the ears of rabbits, which are in rich in blood supply. Host species ''S. c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
George Henry Evans Hopkins
George Henry Evans Hopkins OBE (22 March 1898 – 20 February 1973) was an English entomologist. Hopkins made major contributions in scientific research into three groups of insects – lice, fleas and mosquitoes. He was regarded as a great scientist, with multidisciplinary training and experiences. Early life George Henry Evans Hopkins ("Harry") was born in Hanley in Staffordshire on 22 March 1898, the son of the Rev. George Blagden Hopkins, curate of Hanley, and his wife, Hannah Fletcher Evans. He was educated at Upholland Grammar School in Orrell and Rossall School near Fleetwood in Lancashire (1911–1916).

Boutonneuse Fever
Boutonneuse fever (also called Mediterranean spotted fever, ''fièvre boutonneuse'', Kenya tick typhus, Indian tick typhus, Marseilles fever, or Astrakhan fever) is a fever as a result of a rickettsial infection caused by the bacterium '' Rickettsia conorii'' and transmitted by the dog tick ''Rhipicephalus sanguineus''. Boutonneuse fever can be seen in many places around the world, although it is endemic in countries surrounding the Mediterranean Sea. This disease was first described in Tunisia in 1910 by Conor and Bruch and was named ''boutonneuse'' ( French for "spotty") due to its papular skin-rash characteristics. Presentation After an incubation period around seven days, the disease manifests abruptly with chills, high fevers, muscular and articular pains, severe headache, and photophobia. The location of the bite forms a black, ulcerous crust (''tache noire''). Around the fourth day of the illness, a widespread rash appears, first macular and then maculopapular, and somet ...

Zoonosis
A zoonosis (; plural zoonoses) or zoonotic disease is an infectious disease of humans caused by a pathogen (an infectious agent, such as a virus, bacterium, parasite, fungi, or prion) that can jump from a non-human vertebrate to a human. When humans infect non-humans, it is called reverse zoonosis or anthroponosis. Major modern diseases such as Ebola and salmonellosis are zoonoses. HIV was a zoonotic disease transmitted to humans in the early part of the 20th century, though it has now evolved into a separate human-only disease. Human infection with animal influenza viruses is rare, as they do not transmit easily to or among humans. However, avian and swine influenza viruses in particular possess high zoonotic potential, and these occasionally recombine with human strains of the flu and can cause pandemics such as the 2009 swine flu. Zoonoses can be caused by a range of disease pathogens such as emergent viruses, bacteria, fungi and parasites; of 1,415 pathogens known t ...

Charles Rothschild
Nathaniel Charles Rothschild (9 May 1877 – 12 October 1923) was an English banker and entomologist and a member of the Rothschild family. He is remembered for 'the Rothschild List', a list he made in 1915 of 284 sites across Britain that he considered suitable for nature reserves. Family Nathaniel Charles Rothschild was born in London into the Rothschild family, a prominent Jewish family of bankers. His parents, Nathan Rothschild, 1st Baron Rothschild, and Emma Rothschild (''née'' von Rothschild), were cousins. Charles boarded at Harrow School, which he found somewhat traumatising for incidents of bullying on account of his religion. He worked as a partner in the family bank N M Rothschild & Sons in London. He went to Rothschild's Bank every morning; despite all his interest in science and in natural history, he never missed a day. He was also very interested in the gold refinery operated by Rothschild's, and invented a variety of devices for collecting gold, and working ...
