6728 Old McLean Village Drive, McLean, VA 22101 Tel: 571.488.6000 Fax: 703.556.8729 www.clintox.org Date: 1/9/2017 Question: Botulism is an uncommon disorder caused by toxins produced by Clostridium botulinum. Seven subtypes of botulinum toxin exist (subtypes A, B, C, D, E, F and G). Which subtypes have been noted to cause human disease and which ones have been reported to cause infant botulism specifically in the United States? Answer: According to the cited reference “Only subtypes A, B, E and F cause disease in humans, and almost all cases of infant botulism in the United States are caused by subtypes A and B. Botulinum-like toxins E and F are produced by Clostridium baratii and Clostridium butyricum and are only rarely implicated in infant botulism” (Rosow RK and Strober JB. Infant botulism: Review and clinical update. 2015 Pediatr Neurol 52: 487-492) Date: 1/10/2017 Question: A variety of clinical forms of botulism have been recognized. These include wound botulism, food borne botulism, and infant botulism. What is the most common form of botulism reported in the United States? Answer: According to the cited reference, “In the United States, infant botulism is by far the most common form [of botulism], constituting approximately 65% of reported botulism cases per year. Outside the United States, infant botulism is less common.” (Rosow RK and Strober JB. Infant botulism: Review and clinical update. 2015 Pediatr Neurol 52: 487-492) Date: 1/11/2017 Question: Which foodborne pathogen accounts for approximately 20 percent of bacterial meningitis in individuals older than 60 years of age and has been associated with unpasteurized milk and soft cheese ingestion? Answer: According to the cited reference, “Listeria monocytogenes, a gram-positive rod, is a foodborne pathogen with a tropism for the central nervous system. -

The morphological features of this species were examined indirectly by image analyses software. This finding also supports the documented occurrence of the diamondback puffer fish along Turkish coasts. Keywords: TTX, pufferfish, invasion, range expansion, Eastern Mediterranean Received: 03.05.2018, Accepted: 29.05.2018 To date, the family Tetraodontidae has contributed and established the highest number of alien fish species in the Mediterranean Sea, being represented by ten members out of a total of 165 confirmed non-indigenous fish species in the Mediterranean so far (Golani et al. 2017). Those are Lagocephalus guentheri (Miranda Riberio, 1915); Lagocephalus suezensis (Clark et Gohar, 1953); Lagocephalus sceleratus (Gmelin, 1789); Lagocephalus spadiceus (Richardson, 1845); Torquigener flavimaculosus (Hardy et Randall, 1983); Tylerius spinosissimus (Regan, 1908); Sphoeroides spengleri (Bloch, 1785); Sphoeroides pachygaster (Muller et Troschel, 1848); Sphoeroides marmoratus (Lowe, 1938); and Ephippion guttifer (Bennett, 1831) (Golani et al. -

Seafood Poisoning Symptom, Treatment and Prevention

It can be caused by bacteria, viruses, parasites, enterotoxins, mycotoxins, chemicals, histamine poisoning (scombroid) ciguatera and harmful algal bloom (HAB). Illness can also result by red tide while breathing in the aerosolized brevitoxins (i.e. PbTx or Ptychodiscus toxins). Bacterial toxin food poisoning can affect within 1-6 hours and 8-16 hours, and illness can be with or without bloody diarrhea. The common symptoms of food poisoning include abdominal cramps, vomiting and diarrhea. Diagnosis includes examination of leftover food, food preparation environment, food handlers, feces, vomitus, serum and blood. Treatment involves oral rehydration, antiemetic, and anti-peristaltic drugs. Antimicrobial agents may be needed in the treatment of shigellosis, cholera, lifesaving invasive salmonellosis and typhoid fever. Proper care in handling and cooking is important to prevent any food borne diseases. -
