George Calvin Royal Jr (August 5, 1921 - November 24, 2016) was an American microbiologist. George C. Royal was also part of one of the few African-American husband-and-wife teams in science, working with Gladys W. Royal, Ph.D. on research supported by the United States Atomic Energy Commission. George C. Royal is a professor emeritus at Howard University.
Royal was born in Williamston, South Carolina, [1] in 1921, the oldest boy of nine children of African-American and Native American descent. His father, George Sr., owned an auto garage there before migrating his family to Urbana, Ohio, during the Great Depression.
Royal attended Tuskegee Institute from 1939 to 1943, earning a B.S. in Biology before serving in the Army in World War II as a munitions sergeant, ending at the Battle of the Bulge in 1945. After the war, he attended the University of Wisconsin, where he received an M.S. in microbiology in 1947. Royal took on positions as Bacteriology instructor at Tuskegee in 1947–48; research assistant at Ohio State University and Ohio Agricultural Experiment Station from 1948 to 1952. He was assistant professor of Bacteriology at North Carolina Agricultural and Technical College (now North Carolina Agricultural and Technical State University) in Greensboro from 1952 to 1955. [2]
In 1955 Royal gained admission to the University of Pennsylvania, where he received his Ph.D. in microbiology as a predoctoral fellow in 1957. Royal was associate and professor of Bacteriology at North Carolina Agricultural and Technical College in Greensboro from 1957 to 1965; and in 1959 he served a summer research fellowship for the United States Atomic Energy Commission, Biology Division, at Oak Ridge Institute of Nuclear Studies. He was the dean of the Graduate School at North Carolina Agricultural and Technical College in Greensboro from 1961 to 1965. Following a postdoctoral study in allergy and hypersensitivity and an assistant professorship in Microbiology at Jefferson Medical College in Philadelphia from 1965 to 1966, he joined the faculty of Howard University from 1966 to 1993. He became professor emeritus in 1993. [2]
Royal married Gladys Geraldine Williams in 1947 while attending the University of Wisconsin. Gladys W. Royal (1926–2002) was an African-American biochemist, who graduated from Dillard University with a B.Sc. at the age of 18 in 1944, received an M.Sc. from Tuskegee in 1954, and would receive her Ph.D. from Ohio State University several years later - a rare feat for an African-American female in the 1950s. [3] The Royals would collaborate on important research including that funded by the United States Atomic Energy Commission involving bone marrow transplants to treat radiation overdoses. [4] [5] [6] [7] [8]
African-American husband-and-wife teams in science were extremely rare in the early and mid-20th century due to the social, educational and economic climate regarding African Americans in the United States. [1] [9]
The Atomic Energy Commission supported at least five grants for funding research on bone marrow transplants, which were proposed jointly by George and Gladys W. Royal. [4] [7] Their work was written and presented at various conferences, including the Fifth International Congress on Nutrition Washington, DC 1960 [4] and the International Congress on Histochemistry and Cytochemistry held in Paris, France in 1960. [4]
George C. Royal collaborated at Howard University with Dr. Calvin Sampson and others to develop serological procedures having prognostic value in candidiasis; [10] with Dr. Arvind Nandedkar to study antigenic compounds associated with Candida albicans; [11] with Dr. Robert Watkins and Dr. Arvind Nandedkar to develop antibodies to nortriptyline as a method of reducing toxicity; and with Dr. Richard Garden in the department of Oral Surgery to study the effects of Chlorhexidine on the growth of clinical isolates of Candida species.
Royal had six children: George Calvin Royal III, [1] Geraldine Gynnette Royal, [1] Guericke Christopher Royal, [1] jazz musician Gregory Charles Royal, [15] Michelle Renee McNear, and Eric Marcus Royal.
Tuskegee University is a private, historically black land-grant university in Tuskegee, Alabama. It was founded on July 4th in 1881 by the Alabama Legislature.
Candida albicans is an opportunistic pathogenic yeast that is a common member of the human gut flora. It can also survive outside the human body. It is detected in the gastrointestinal tract and mouth in 40–60% of healthy adults. It is usually a commensal organism, but it can become pathogenic in immunocompromised individuals under a variety of conditions. It is one of the few species of the genus Candida that cause the human infection candidiasis, which results from an overgrowth of the fungus. Candidiasis is, for example, often observed in HIV-infected patients. C. albicans is the most common fungal species isolated from biofilms either formed on (permanent) implanted medical devices or on human tissue. C. albicans, C. tropicalis, C. parapsilosis, and C. glabrata are together responsible for 50–90% of all cases of candidiasis in humans. A mortality rate of 40% has been reported for patients with systemic candidiasis due to C. albicans. By one estimate, invasive candidiasis contracted in a hospital causes 2,800 to 11,200 deaths yearly in the US. Nevertheless, these numbers may not truly reflect the true extent of damage this organism causes, given new studies indicating that C. albicans can cross the blood–brain barrier in mice.
Candida is a genus of yeasts. It is the most common cause of fungal infections worldwide and the largest genus of medically important yeasts.
Microbial art, agar art, or germ art is artwork created by culturing microorganisms in certain patterns. The microbes used can be bacteria, yeast, fungi, or less commonly, protists. The microbes can be chosen for their natural colours or engineered to express fluorescent proteins and viewed under ultraviolet light to make them fluoresce in colour.
Oral ecology is the microbial ecology of the microorganisms found in mouths. Oral ecology, like all forms of ecology, involves the study of the living things found in oral cavities as well as their interactions with each other and with their environment. Oral ecology is frequently investigated from the perspective of oral disease prevention, often focusing on conditions such as dental caries, candidiasis ("thrush"), gingivitis, periodontal disease, and others. However, many of the interactions between the microbiota and oral environment protect from disease and support a healthy oral cavity. Interactions between microbes and their environment can result in the stabilization or destabilization of the oral microbiome, with destabilization believed to result in disease states. Destabilization of the microbiome can be influenced by several factors, including diet changes, drugs or immune system disorders.
Microbiology is the scientific study of microorganisms, those being of unicellular (single-celled), multicellular, or acellular. Microbiology encompasses numerous sub-disciplines including virology, bacteriology, protistology, mycology, immunology, and parasitology.
Mycobiota are a group of all the fungi present in a particular geographic region or habitat type. An analogous term for Mycobiota is funga.
