What is the microscopic morphology of Rhodococcus sp?
Rhodococcus equi morphology varies from bacillary to coccoid, depending on the growth conditions: while bacteria are rod shaped after 4 h of growth in culture broth, they become coccoid after a day of growth in liquid media or on blood agar (Fuhrmann et al., 1997).
Where is Rhodococcus Rhodochrous found?
contaminated soil
The species, Rhodococcus rhodochrous, is usually isolated from contaminated soil which does not contribute to any pathogenesis [2]. Many strains of Rhodococcus are considered as significant part of the soil microbial community because of their diverse biodegradation mechanisms [1].
Is Rhodococcus an actinobacteria?
Rhodococcus equi is the only recognized animal pathogenic species within an extended genus of metabolically versatile Actinobacteria of considerable biotechnological interest.
Is Rhodococcus Gram positive or negative?
gram-positive bacteria
Pathogen name and classification Rhodococcus is a facultative intracellular, gram-positive bacteria.
Is Rhodococcus aerobic or anaerobic?
Rhodococcus equi are Gram-positive, obligate aerobic bacteria. They are catalase-positive, mostly urease-positive and oxidase-negative and their optimal growth temperature is between 30 and 371C (Prescott, 1991).

What is Rhodococcus Rhodochrous used for?
Rhodococcus rhodochrous is a bacterium used as a soil inoculant in agriculture and horticulture. It is gram positive, in the shape of rods/cocci, oxidase negative, and catalase positive. It is industrially produced to catalyse acrylonitrile conversion to acrylamide.
Is Rhodococcus intracellular?
Abstract. Rhodococcus equi is a facultative intracellular bacterium of macrophages that causes disease in immunocompromised individuals, particularly those with AIDS.
What is Rhodococcus equi infection?
Rhodococcus equi is a zoonotic organism which is a frequent cause of disease in a number of animals, including being the most common cause of pneumonia in foals [1]. It is a non-motile gram positive coccoid or bacillary organism found in high numbers on dry surface soil of farming and livestock properties [1].
Is Rhodococcus acid-fast?
Rhodococcus equi is an aerobic Gram-positive and acid-fast coccobacillus that may cause cavitary pneumonia in immunocompromised hosts such as HIV-infected patients.
How do you treat Rhodococcus?
How is Rhodococcus equi treated? Antibiotics such as erythromycin, clarithromycin, and azithromycin can be used to treat R. equi infection in horses, but they can also result in potentially serious side effects such as diarrhea and overheating (hyperthermia).
How is Rhodococcus diagnosed?
Rhodococcus equi is diagnosed based on known history of cases on the farm (indicating presence of the bacteria on the grounds), ultrasound and/or x-ray evidence of abscesses in the lungs, bloodwork, and identification of the bacteria by culture and/or PCR testing.
How does Rhodococcus equi affect humans?
Abstract. More than 100 cases of Rhodococcus equi infection have been reported since the first description of human disease caused by this organism. The vast majority of patients infected with R. equi are immunocompromised, and two-thirds have human immunodeficiency virus infection.
What disease does Rhodococcus cause?
How is Rhodococcus equi diagnosed?
Is Rhodococcus spore forming?
Rhodococcus, which belongs to the family Nocardiaceae, is a genus of aerobic, nonmotile, non-spore-forming, Gram-positive bacteria.
