Seborrhoeic dermatitis, sometimes inaccurately referred to as seborrhoea, is a long-term skin disorder. Symptoms include red, scaly, greasy, itchy, and inflamed skin. Areas of the skin rich in oil-producing glands are often affected including the scalp, face, and chest. It can result in social or self-esteem problems. In babies, when the scalp is primarily involved, it is called cradle cap. Dandruff is a milder form of the condition without inflammation.
Contact dermatitis is a type of acute or chronic inflammation of the skin caused by exposure to chemical or physical agents. Symptoms of contact dermatitis can include itchy or dry skin, a red rash, bumps, blisters, or swelling. These rashes are not contagious or life-threatening, but can be very uncomfortable.
Bartonella henselae, formerly Rochalimæa henselae, is a bacterium that is the causative agent of cat-scratch disease (bartonellosis).
Tick-borne diseases, which afflict humans and other animals, are caused by infectious agents transmitted by tick bites. They are caused by infection with a variety of pathogens, including rickettsia and other types of bacteria, viruses, and protozoa. The economic impact of tick-borne diseases is considered to be substantial in humans, and tick-borne diseases are estimated to affect ~80 % of cattle worldwide.
Bartonella is a genus of Gram-negative bacteria. It is the only genus in the family Bartonellaceae. Facultative intracellular parasites, Bartonella species can infect healthy people, but are considered especially important as opportunistic pathogens. Bartonella species are transmitted by vectors such as ticks, fleas, sand flies, and mosquitoes. At least eight Bartonella species or subspecies are known to infect humans.
Carrion's disease is an infectious disease produced by Bartonella bacilliformis infection.
Bartonellosis is an infectious disease produced by bacteria of the genus Bartonella. Bartonella species cause diseases such as Carrión's disease, trench fever, cat-scratch disease, bacillary angiomatosis, peliosis hepatis, chronic bacteremia, endocarditis, chronic lymphadenopathy, and neurological disorders.
Hippoboscidae, the louse flies or keds, are obligate parasites of mammals and birds. In this family, the winged species can fly at least reasonably well, though others with vestigial or no wings are flightless and highly apomorphic. As usual in their superfamily Hippoboscoidea, most of the larval development takes place within the mother's body, and pupation occurs almost immediately.
Lipoptena cervi, the deer ked or deer fly, is a species of biting fly in the family of louse flies, Hippoboscidae. These flies are commonly encountered in temperate areas of Europe, Siberia, and northern China. They have been introduced to North America. They are parasites of elk, deer, and other deer family members, burrowing through the fur and sucking the blood of the host animals. Adults are only 5–7 mm (0.20–0.28 in) in length and brownish in colour. Their bodies are flat and elastic, making their removal difficult. L. cervi is a poor flier and can only fly for short distances. Once the insect reaches its target, it sheds its wings and starts burrowing through the fur.
Lipoptena mazamae, the Neotropical deer ked, is a fly from the family Hippoboscidae. They are blood-feeding parasites of the white-tailed deer - Odocoileus virginianus in the southeastern United States and Central America, the red brocket deer - Mazama americana in Mexico to northern Argentina, and also an incidental parasite of domestic cattle, Cougars - Puma concolor, and man.
Lipoptena depressa, or the Western American deer ked, is species of fly in the family Hippoboscidae. The flies are blood-feeding ectoparasites of mule deer, Odocoileus hemionus and white-tailed deer, Odocoileus virginianus. They are found in the western United States and Canada.
Eyelid dermatitis is commonly related to atopic dermatitis or allergic contact dermatitis. Volatile substances, tosylamide, epoxy hardeners, insect sprays, and lemon peel oil may be implicated, with many cases of eyelid contact dermatitis being caused by substances transferred by the hands to the eyelids.
Cat-scratch disease (CSD) or felinosis is an infectious disease that most often results from a scratch or bite of a cat. Symptoms typically include a non-painful bump or blister at the site of injury and painful and swollen lymph nodes. People may feel tired, have a headache, or a fever. Symptoms typically begin within 3–14 days following infection.
Alopecia in animals is a condition where locations on the body surface that are typically covered in hair, contain areas where hair is absent, and is a condition that can affect other animals besides humans. Alopecia is a condition that can affect wild organisms and captive organisms, however, the condition tends to be more prominent in captive contexts. Development of alopecia in animals is usually the sign of an underlying disease. Some animals may be genetically predisposed to hair loss, while in some it may be caused by hypersensitivity or nutritional factors. These include Moluccan cockatoos, spectacled bears, hedgehogs, raccoons, squirrels, baboons, and chimpanzees since they share 98% of human genes. Others that are selectively bred to have baldness include rabbits, guinea pigs, Syrian hamsters, mice, rats, and cats. Environmental enrichment has been used in some cases to mitigate certain behaviours that cause hair loss, improve alopecia, and address welfare concerns.
Arsenophonus is a genus of Morganellaceae, of the Gammaproteobacteria. Members of the Arsenophonus genus are increasingly discovered bacterial symbionts of arthropods that are estimated to infect over 5% of arthropod species globally and form a variety of relationships with hosts across the mutualism parasitism continuum. Arsenophonus bacteria have been identified in a diversity of insect taxa, including economically important species such as the Western honey bee and the rice pest Nilaparvata lugens.
Bartonella chomelii is a Gram-negative, oxidase- and catalase-negative bacteria from the genus Bartonella with a unipolar flagellum which was isolated from a domestic cattle. Bartonella chomelii is named after Bruno B. Chomel.
Bartonella clarridgeiae is a Gram-negative bacteria from the genus Bartonella which was first isolated in the United States. Bartonella clarridgeiae is a zoonotic pathogen which can cause cat scratch disease.
Bartonella pachyuromydis is a bacterium from the genus Bartonella which was isolated from Rodentia.
Bartonella silvatica is an oxidase- and catalase-negative bacterium from the genus Bartonella isolated from the blood of the large Japanese field mouse Apodemus speciosus.
Bartonella ancashensis is a bacterium from the genus Bartonella which has been isolated from blood from patients who suffered from verruga peruana in Caraz in Peru. Bartonella ancashensis is a human pathogen which may cause verruga peruana.
