11:14 AM | WHO MERS-CoV Update KSA & UAE – April 10th
Photo Credit NIAID     # 8456   The World Health Organization has posted an update on the MERS coronavirus, with details on 5 recent cases (4 from Saudi Arabia, 1 from the UAE).  The two cases from Jeddah are part of a much larger event (see Saudi MOH Statement On Jeddah Cluster) which has received considerable attention over the past couple of days, and additional case information is expected.     Middle East respiratory syndrome coronavirus […]

11:00 AM | Talmudic Question #107
Suppose you are once again strolling on that deserted beach and again, on cue, the genie reappears. This time he is offering you some mice from a lineage that he has bred for hundreds or more generations under germ-free conditions. Would you expect to find any genetic changes in these mice? If so, what might they be?

10:52 AM | Revisiting Tamiflu Efficacy (Again)
      # 8455   Just over two years ago in The Tamiflu Controversy Continues, we looked at the ongoing debate over the effectiveness of oseltamivir (Tamiflu ®) in the wake of the release of a Cochrane group analysis that found insufficient evidence to show whether the drug reduces influenza complications and transmission.   Three weeks later the CDC responded with a statement on their Have You Heard? website, which published their rationale for continuing to […]

6:36 AM | Racing up the Best Seller's List
Currently #285,426 on Amazon's best seller list (how the hell did it get that high?) is our new book on Molecular Methods in Environmental Microbiology. Andy and I would like to thank all our contributors for their hard work and their patience, as this book took a long time to see the light of day. I now remember why it was over a decade since I last edited a book.

5:02 AM | Resources For Blastocystis Epidemiology Research
 I often get questions related to Blastocystis epidemiology research, and many of these are 'how-to' questions.And as announced, I've chosen to dedicate a separate post listing some easy-to-use tools for subtyping Blastocystis from humans and animals.First, I want to guide your attention to the YouTube video that I made; it takes you through various important steps of subtyping and introduces you to the online database that can be used to call subtypes by BLASTing batches of fasta files - […]

2:28 AM | And in non shocking news of the day - more overselling of the microbiome
Well, just read this story: Possible link between bacteria and breast cancer: study | CTV London News.  Serious overselling of the microbiome going on here.  As far as I can tell, all that was shown in the work discussed here (for which there is no publication or presentation of any kind reported) is that the bacteria found in canecrous breast tissue differs from that in non cancerous tissue.  Interesting perhaps.  But not really that informative as just about every […]

  # 8454   A sign of increasing concern among residents of Saudi Arabia is that Arabic social media – in particular twitter – has gone ballistic this morning over the MERS coronavirus.     I’m tracking about 30 new tweets a minute containing the word  كورونا (`SK’ or `Corona’) coming across the transom, many with photos attached.  Before Chrome can auto translate a batch, another […]

2:17 PM | Helper's available...
Greetings,       Immune system is a subject of interest to us for a variety of reasons. Vaccines is just one of them (but considered a major). However, here is an important point made by someone. Most of the vaccines that have been created are not the work of immunologist, but rather a microbiologist who by trial and error, comes across a potential antigen which may be significant. Further experiments, establishes how the immune system works. Such a reverse approach is often […]

11:28 AM | Xinhua News: Extensive H5N1 Outbreaks In North Korean Poultry
  # 8452   Although we occasionally get hints of outbreaks of bird flu, or FMD, in North Korea, very rarely do we details out of that closed and secretive nation. Given the amount of bird flu activity (H5N1 & H5N8) we’ve seen reported out of South Korea over the past decade, the assumption has been that unreported bird flu outbreaks probably occur with some regularity in the DPRK as well.   This morning Yonhap News, Xinhua News, and others are reporting on a […]

  # 8451   Although most of the MERS-CoV reportage the past week has centered around Jeddah (see Saudi MOH Statement On Jeddah Cluster), the Riyadh region continues to provide its share of Coronavirus reports as well.  On April 2nd we saw a report of 2 cases in the Saudi Capital, and overnight the MOH has announced an additional 4 cases there.   Unlike in Jeddah, where some cases have been described as asymptomatic, all four of these cases are serious enough to […]
