3D model of Megalosaurus bucklandii specimen based on illustrations by Robert Plot and Richard Brookes

The first technical image of a dinosaur specimen was published in 1677. It appeared in Robert Plot's <i>The Natural History of Oxford-Shire: Being an Essay Toward the Natural History of England</i>. A similar illustration of this specimen was published 86 years later in Richard Brookes' <i>New and Accurate System of Natural History, </i>this time appearing beside the caption <i>"</i>Scrotum humanum." Brookes dismisses Plot's notion that the rock is the remnant of a mythical giant human, yet assigned it a binomial name, likely due to his perception that the offending object resembles a human scrotum

Prevalence of antibiotic resistant Escherichia coli isolates from fecal samples of food handlers in Qatar

Abstract Background It is well documented that food handlers harbor and shed enteric foodborne pathogens causing foodborne disease outbreaks. However, little known on enteric antibiotic resistant (AR) bacteria carriage in food handlers. The objective of this study was to establish a baseline prevalence of fecal AR E. coli among food handlers in Qatar. Methods Fecal samples were collected from 456 migrant food handlers of different nationalities arriving in Qatar on a work permit between January 2015 and December 2016. These samples (25 g each) were collected based on the availability and examination schedule at the Medical Commission facility from those consented to participate. Isolated E. coli bacteria were tested for antibiotic susceptibility against nine antibiotics using the E-test method and Double Disc Synergy Test (DDST) for extended-spectrum beta-lactamase (ESBL) production. Results From the 78 E. coli positive samples (17.1%, n = 456), 60% of the isolates were resistant to at least one antibiotic, whereas, 27% were multi-drug resistant (MDR). Seven isolates (9%, n = 78) were ESBL producers of which five were MDR. Individual AR E. coli frequencies to the nine antibiotics were not significantly (P > 0.05) different by nationality. Conclusions Based on our findings, we revealed that individual resistant E. coli and MDR resistant E. coli were common in fecal samples of food handlers in Qatar. This may indicate that food handlers can potentially contaminate foods with AR E. coli, a possible public health concern
