Talk:Yersinia

adding species
Recently I've been involved in research of enterobacteria. Thus, I will be updating the page and adding several species that have not previously been included. The Enterobacteria by J. Janda (2006) is my source. Jhay116 (talk) 15:44, 12 June 2009 (UTC)


 * Please remember to cite your source inline whenever you draw on it; a single citation here isn't enough. Check out the Wikipedia style manual for more details. Thanks! This article could use your help. Mote (talk) 22:22, 27 July 2009 (UTC)

Restoring tag
A paragraph that begins with Speculations exist as to whether or not certain Yersinia can... needs a supporting citation. Thus I've restored the tag. -- MarcoTolo 22:44, 25 January 2007 (UTC)

- The third paragraph states that: "Yersinia representatives also reveal relatively high heat resistance, some of them being able to survive 50-60 degrees Celsius temperature for up to 20-30 minutes and (arguably, might be due to misreading of information like the first external link below) surviving standard pasteurization process (15 seconds at 72 degrees Celsius) in milk".

A quick search of the literature provides no support for this statement; in fact, the opposite appears to be true. Marth and Steele (Applied Dairy Microbiology, 2nd edition, p487, Marcel Dekker Inc. New York) note "high susceptibility of the organism to pasteurization" in reference to Y. enterolitica. In addition, the following link: notes "The organism is susceptible to mild heat (55°C), as well as to exposure to most hospital disinfectants", in reference to Y. pestis. There is no physiological or morphological basis to assume that other members of the genus should demonstrate susceptibility to pasteurization which differs from these two species. (Joklik et al., Microbiology, 17th ed., Appleton-Century-Crofts, New York, 1980.)

Suggest the article be amended to state that “Yersinia representatives show no remarkable heat resistances” or the original statement simply be removed. Drakaran (talk) 17:28, 21 January 2009 (UTC)


 * I removed the statement. The BBC link was misleading; it's about a similarly-named Mycoplasma species. Mote (talk) 22:01, 27 July 2009 (UTC)
