Human oral anaerobic diphtheroids: biochemical and serological reactivity

The Identification and Enumeration of Actinomyces from Plaque of New Guinea Indigenes

“…Catalase activity was tested by adding 3% H20 , to cultures grown aerobically on BHI agar. Antisera were prepared against Actinomyces viscosus NY 1, A. odontolyticus NCTC 9931, A. israeli WVU 307 and A. naeslundii ATCC 12104 using the procedure described by Beveridge and Goldner [1973], Agglutination titres were deter mined by adding a standard suspension of organ isms (OD = 0.5 at 500 nm in 1 cm cell) to serial 2-fold dilations of serum.…”

Statistical Relationship Between the Presence of Human Subgingival Anaerobic Diphtheroids and Periodontal Disease

“…These quantitative results were confirmed qualitatively by indirect fluorescent antibody tests. 6 The incidence of anaerobic diphtheroids in periodontally diseased and clinically nor- J Dent Res May-Jine 1973 mal mouths was evaluated on a statistical basis. Table 1 shows that 26 % of the periodontally diseased group were positive for the isolation of a strict anaerobic diphtheroid, whereas only 4% of the clinically normal group were positive.…”

“…6 Four separate sampling groups constituted the source of the total collection of plaque material studied (Table 1). Groups 1 and 2 (28 and 16 samples, respectively) were taken at different times from the dental clinic at the Faculty of Dentistry (Toronto).…”

Training the next scientific generation – A tribute to Terrance J. Beveridge

“…After receiving an undergraduate degree in general science in 1968, he obtained a post‐baccalaureate diploma in microbiology in 1969. He then continued his studies in microbiology with Morris Goldner, receiving an MSc in 1970 (Beveridge & Goldner, 1973). During this time, Terry became quite interested in microscopy, particularly microbiological details that could only be observed using an electron microscope.…”
