Necrotising fasciitis is one of the fatal skin and soft tissue infections. Vibrio vulnificus is a rare cause of necrotising fasciitis; however, the disease is one of the major manifestations of the bacteria. Here, we report one such case in a middle-aged male patient. He presented with the signs of bilateral lower limb cellulitis and altered sensorium. V. vulnificus was isolated from blood culture and also from debrided tissue. Though the organism is well characterised, it is a rare causative agent of necrotising fasciitis...

Necrotizing fasciitis (NF) is a bacterial dermo-hypodermitis affecting the soft tissue and muscular fascia. It is an uncommon and severe infection caused by microorganisms called 'flesh eating bacteria', mainly represented by group A beta-haemolytic streptococcus. NF remains a life-threatening condition associated with a high mortality rate. Its location on the chest wall is extremely rare. The few reported cases are subsequent to thoracic drainage, lung surgery or esophageal resection. This is a case report of an 80-year old female with comorbidity of heart disease, a past history of coronary artery by-pass and diabetes...

Recent news headlines claimed that corpses thrown into Syrian streets are causing cutaneous leishmaniasis (CL) outbreaks. However, leishmaniasis is only transmitted by blood-feeding sandflies, not through human remains. High CL prevalence in Syria may instead be attributed to the absence of disease control programs due to the disruption of health services.

Human CD46 is a receptor for the M protein of group A streptococcus (GAS). The emm1 GAS strain GAS472 was isolated from a patient suffering from streptococcal toxic shock-like syndrome. Human CD46-expressing transgenic (Tg) mice developed necrotizing fasciitis associated with osteoclast-mediated progressive and severe bone destruction in the hind paws 3 days after subcutaneous infection with 5 × 10(5) colony-forming units of GAS472. GAS472 infection induced expression of the receptor activator of nuclear factor-κB ligand (RANKL) while concomitantly reducing osteoprotegerin expression in the hind limb bones of CD46 Tg mice...

Necrotizing fasciitis (NF) of the cervicofacial area is highly rare, but physicians should be familiar with the presentation of this situation owing to the suddenness of its beginning, the rapidness of its spread, and ending with high mortality and morbidity. In this article, 5 patients with NF admitted to emergency department with dental pathology history were discussed with a review of the literature. The purpose of this case series is to raise awareness about NF of the cervicofacial area caused by dental pathologies...

The identification of the molecular events responsible for strain emergence, enhanced virulence, and epidemicity has been a long-pursued goal in infectious diseases research. A recent analysis of 3,615 genomes of serotype M1 group A Streptococcus strains (the so-called "flesh-eating" bacterium) identified a recombination event that coincides with the global M1 pandemic beginning in the early 1980s. Here, we have shown that the allelic variation that results from this recombination event, which replaces the chromosomal region encoding secreted NADase and streptolysin O, is the key driver of increased toxin production and enhanced infection severity of the M1 pandemic strains...

To determine the ideal ripening stage for consumption of the mango cultivars, "Ataulfo," "Haden," and "Tommy Atkins"; fruits at 3 flesh firmness levels (ripeness stages) were evaluated by a trained panel using descriptive analysis after instrumental measurements were made. After harvest, all fruits were ripened to allow softening and quality and sensory attribute changes. Ripening changes during softening of Ataulfo mangos were expressed by a characteristic increase in the perception of "tropical fruit" and "peach" aromas, an increase in "juiciness," "sweetness," and "tropical fruit" flavor, while "fibrousness," "chewiness," and "sourness" decreased...

The increasing awareness that dried fish protein can be applied for food fortification and production of value added/functional foods has encouraged the food industry to examine different methods for developing fish protein ingredient from different raw materials. Fish protein powder (FPP) is a dried and stable fish product, intended for human consumption, in which the protein is more concentrated than in the original fish flesh. Quality and acceptability of FPP depend on several factors. The fat content of the FPP is a critical issue because when it is oxidized a strong and often rancid flavour is produced...

Samples of seven species of cephalopods and crustaceans were collected from major fish markets on the Korean coast and analyzed for mercury (Hg) using a direct Hg analyzer and for the metals cadmium (Cd), lead (Pb), chromium, silver, nickel, copper, and zinc using inductively coupled plasma mass spectrometry. The distributions of heavy metals in muscles, internal organs, and whole tissues were determined, and a risk assessment was conducted to provide information concerning consumer safety. The heavy metals accumulated to higher levels (P < 0...

As criticisms of factory farming continue to mount, an increasing number of individuals have changed their existing dietary practices. Perhaps the two most important food movements reacting against industrial farming are (1) vegetarianism, the avoidance of animal flesh; and (2) conscientious omnivorism (CO), the consumption of meat or fish only when it satisfies certain ethical standards. While the former group has been well-studied in the social science literature, there have been few, if any, studies specifically examining those who identify themselves as ethical meat eaters...

Necrotizing fasciitis is an uncommon infection mainly caused by Streptococcus pyogenes, which is also known as flesh-eating bacteria. It is often caused by bacteria, but can also be caused and complicated by fungus. We report a case of bacterial necrotizing fasciitis that was complicated by a fatal fungal infection, a rare clinical presentation affecting the upper limbs, head and neck, in a young diabetic female patient. It was an unsuspected case of fungal infection with mucormycosis, which proved to be fatal due to a delay in diagnosis and treatment...

The phylogeny of piranhas, pacus, and relatives (family Serrasalmidae) was inferred on the basis of DNA sequences from eleven gene fragments that include the mitochondrial control region plus 10 nuclear genes (two exons and eight introns). The new data were obtained for a representative sampling of 53 specimens, collected from all major South American rivers, accounting for over 40% of the valid species and all genera excluding Utiaritichthys. Two fossil calibration points and relaxed-clock Bayesian analyses were used to estimate the timing of diversification...

Self-mutilation is a general term for a variety of forms of intentional self-harm without the wish to die. Although there have been many reports of self-mutilation injuries in the literature, none have reported self-cannibalism after self-mutilation. In this article we present a patient with self-cannibalism following self-mutilation. A 34-year-old male patient was brought to the emergency department from the prison with a laceration on the right leg. Physical examination revealed a well-demarcated rectangular soft tissue defect on his right thigh...

An apparent contradiction in the ecology of cycad plants is that their seeds are known to be highly poisonous, and yet they seem well adapted for seed dispersal by animals, as shown by their visually conspicuous seed cones and large seeds presented within a brightly colored fleshy "fruit" of sarcotesta. We tested if this sarcotesta could function as a reward for cycad seed dispersal fauna, by establishing if the toxic compound cycasin, known from the seeds, is absent from the sarcotesta. The Australian cycads Macrozamia miquelii and Cycas ophiolitica were tested (N = 10 individuals per species) using gas chromatography / mass spectrometry...

Vibrio parahaemolyticus is a major cause of foodborne illness and related with the consumption of raw contaminated seafood, especially oysters. To evaluate the effectiveness of various applications of a bacteriophage (phage), pVp-1, against a multiple-antibiotic-resistant V. parahaemolyticus pandemic strain (CRS 09-17), we designed artificial contamination models that are most likely to be encountered during oyster processing. When live oysters were treated with bath immersion with pVp-1 after CRS 09-17 challenge, the growth of bacterial strain was significantly reduced...

The arsenic compounds in marine biota were evaluated from Izmir Bay (Eastern Aegean) and found that inorganic arsenic occurred as a minor fraction. No information is available on the annual variations of arsenic in important edible biota species from Izmir Bay. Fish and mussel samples were taken from different regions of Izmir Bay between 2009 and 2011 (n=854 individual specimens). The average percentages of inorganic arsenic to total arsenic for all biota samples were 3.43±3.38% with a range of 0.11-11.8%...
