Constantine Efthymiou PhD, Retired Professor of Microbiology at St. John’s University, has been recognized by Marquis Who’s Who Top Educators for dedication, achievements, and leadership in microbiology.

Dr. Efthymiou became involved in his profession because coming as a graduate student from Greece his objective was to study at the School of Agriculture. He wanted to be of help to his country by specializing in dairy technology. He discussed it with his professors at Maryland Park and they suggested what he should do. He began to work on it and that was how he got started. When he completed the work, he returned to Greece, wanted to apply there but the conditions were not good and for that reason, he returned to the US. He was hired as an assistant professor of Microbiology at the Carnegie Institute of Technology in Pittsburgh in 1961, moving up to an assistant professor in 1964, remaining until 1968. He then went to St. John’s University in 1968, as an associate professor moving up to professor until his retirement in 1981. He specialized in immunological work and collaborated with doctors in Queens, New York on cervical carcinoma.

Early in his career, Dr. Efthymiou produced an experimental Domestic Feta Cheese from cow’s milk. Following a presentation of results, production and consumption of this cheese in the USA increased phenomenally. Later, he worked on the primary probiotic species of Bacteria Lactobacillus Acidophilus, determining its neotype. In pathology, at a time, the causative agent of cervical carcinoma had not yet been established but using serocytology obtained diagnostic results of improved sensitivity. Dr. Efthymiou earned a Bachelor of Science in agriculture from the University of Athens in 1952. He then came to the United States and matriculated at the University of Maryland receiving a Master of Science in 1958 and a Doctor of Philosophy in 1961.
