A1 Brenner, Don J.YR 1986 T1 Notes: Priority of Providencia rustigianii Hickman-Brenner, Farmer, Steigerwalt, and Brenner 1983 Over Providencia friedericiana Müller 1983 JF International Journal of Systematic and Evolutionary Microbiology, VO 36 IS 4 SP 565 OP 566 DO https://doi.org/10.1099/00207713-36-4-565 PB Microbiology Society, SN 1466-5034, AB Deoxyribonucleic acid hybridization studies done on 24 Providencia friedericiana strains showed that they were highly related (74 to 86% at 75°C) to the type strain of Providencia rustigianii. In addition, their biochemical reactions were the same. Therefore, the names P. rustigianii and P. friedericiana are subjective synonyms. Because P. rustigianii was described and validated first, it is the senior synonym and has priority over the junior synonym, P. friedericiana. , UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/00207713-36-4-565
