Dermatophilus congolensis, the aetiological agent of dermatophilosis, is a pleomorphic, Gram-positive actinomycete, which infects animals and humans. Often, there is a wrong diagnosis of the infection in animals because of the close resemblance of the organism with other members of the family Actinomycetaceae. In this study, molecular tools were applied to suspected isolates of D. congolensis. Dermatophilus congolensis is a gram-positive, non-acid-fast, facultative anaerobic, branching actinomyces. 2 Genotypic and phenotypic variation between isolates has been demonstrated. 3-5 Dermatophilus congolensis has a distinct life cycle and exists in two morphologic forms, hyphae and zoospores. 6,7 Hyphae are composed of filaments that break into coccoid cells We report the first case of Dermatophilus congolensis infection of the human esophagus. We demonstrate initial endoscopic diagnosis, progression and then spontaneous resolution of D. congolensis infection, once the patient's occupational exposure had ceased
Dermatophilosis is a superficial, exudative dermatitis caused by infection with Dermatophilus congolensis. It is more common in hot, humid environments and in areas with heavy rain. Many species are affected, including cattle, sheep, goats and horses. Clinically affected animals present with lesions which begin as small papules and pustules Dermatophilus congolensis can remain dormant on the horse, but when there is trauma to the skin the bacteria is able to gain entrance. The injury to the skin may be caused by the bite of an insect, abrasions or by a laceration. Once the bacteria enters the epidermis it causes pustules (pus filled bumps) that then scab over
Dermatophilus congolensis is an actinomycete that infects the skin of many species, producing a superficial, purulent dermatitis with abundant crust formation. Rabbits are susceptible to infection with D. congolensis and have been used as experimental models to study the disease ( Abu-Samra and Imbabi, 1976; Abu-Samra and Walton, 1981; Bucek et al., 1992; How and Lloyd, 1990 ) Dermatophilus congolensis (D. congolensis) is a well-recognized Gram-positive, non-acid-fast, branching filamentous rod (cocci). These microorganisms are facultative anaerobic, capnophilic or aerobic tolerant bacteria that belong to the Actinomycetales order (QUINN et al., 2011). The pathogen causes exudativ They occur usually due to a repeated wetting of the stratum corneum or skin trauma which makes the skin more vulnerable to parasitism by the causal agent Dermatophilus congolensis. It is more commonly seen in the winter. Typically hair becomes matted and focal lesions develop into crusts and thick scabs covered by layers of yellow-green pus Dermatophilus congolensis (Rain Rot) is a fungus. It occurs most frequently in domestic animals such as horses, goats, and sheep and has been found in wild and captive cervids such as deer, elk, and moose. It thrives in wet weather. Clinical signs include raised, matted tufts of hair, scabs, and hair loss
Background: Dermatophilus congolensis causes a crusting dermatitis that affects horses. Diagnosis requires the identification of the organism with cytological evaluation of crust samples Dermatophilus congolensis, sheep and goats, Tamil Nadu. Introduction. Dermatophilosis is an exudative pustular der-matitis that affects many animals, and occasionally, humans. Dermatophilosis is caused by the bacte-rium . Dermatophilus congolensis (DC).

This species of bacteria is unusual because its life cycle and characteristics are similar to that of a fungus. Dermatophilosis was first described in domestic cattle in Zaire, Africa in 1910 Background. Dermatophilus congolensis is a facultative anaerobic actinomycete that causes papular to exudative dermatitis with crusting in horses. This organism is frequently implicated as a cause of pastern dermatitis, but few data are available validating the organism's association with this disease Dermatophilus congolensis is characterized by its ability to form ﬁlamentous structures with transversal and longitudinal segmentation, ﬁnally evolving to coccoid forms. Colonies on blood agar incubated at 37°C in 5% CO 2 are 0.5-1 mm in diameter after 24 h. Colonies are β-haemolytic
Muk er en samlet betegnelse for infektion nederst på benene, forårsaget af bakterier, svampe, mider eller dermatophilus congolensis. Det er en eksemlignende tilstand D. congolensis is a Gram-positive, non-acid-fast, facultative anaerobic actinomycete with a wide host range and worldwide distribution. The natural habitat for Dermatophilus is unknown, although organic matter is thought to have a protective effect on the organisms, and soil may act as a temporary reservoir Dermatophilus congolensis proliferates in the epidermis to produce filaments. By 14 days post-infection, T cells are present in the upper dermis and plasma cells in the subdermis. After a primary infection, lesion resolution commences around Day 14 and is completed by Day 28 D. congolensis, the type species of the genus Dermatophilus, is a Gram-positive, aerobic bacterium, and is strictly parasitic of the skin but can also survive for some time in the environment. It is a parasite of the living cell layers of the epidermis and does not invade the stratum corneum

Dermatophilosis in sheep (lumpy wool) is a dermatitis caused by the bacterium Dermatophilus congolensis. Dermatophilosis affects a range of animal species including horses, cattle, sheep, goats and humans. Chronically infected sheep with minor active lesions (often on the face and ears) are the main source of infection La infección por Dermatophilus congolensis se circunscribe prácticamente al ámbito animal, pues apenas se han documentado una veintena de casos en hombres. Debido a la querencia de la bacteria por climas cálidos y húmedos, se encuentra sobre todo en las áreas tropicales de Asia, América Central y del Sur, y de África; precisamente, recibe su nombre porque fue en Congo donde se aisló. .
