Fish contamination has been extensively investigated along the Saudi coasts, but studies pertaining to bacterial pathogens are scarce. We conducted qualitative assessment and molecular identification of culture-dependent bacteria in 13 fish species from three coastal sites and a local fish market in Jeddah, Saudi Arabia. Bacterial counts of gills, skin, gut and muscle were examined on agar plates of Macconkey's (Mac), Eosin Methylene Blue (EMB) and Thiosulfate Citrate Bile Salts (TCBS) culture media. Bacterial counts significantly differed between species, sources and feeding habits of examined fishes...

Walnuts (Juglans regia) have been associated with foodborne illness outbreaks in recent years. Thus, the purpose of this study was to investigate the distribution of bacteria on in-shell walnut surfaces from six representative provinces in China. The bacterial populations on walnut surfaces were investigated by high-throughput sequencing based on the bacterial 16 S rRNA hypervariable region V4. Twenty-eight samples were collected from fourteen regions in six provinces and harvested in different periods (the fresh in 2016 and the old in 2015)...

Human immunodeficiency virus (HIV) is well known to be associated with various neoplasms and opportunistic infections. Kaposi sarcoma (KS), associated with human herpes virus 8 (HHV8) infection, is the most common tumour in HIV positive patients and is also an acquired immune deficiency syndrome (AIDS) defining illness. Cutaneous manifestations are the most common presenting symptom; however, visceral involvement is also recognized. We present the case of a 55-year-old male who was diagnosed with AIDS-related KS, who was referred to our surgical unit with an indeterminate left adrenal lesion...

Listeria monocytogenes is a Gram-positive opportunistic human pathogen and it remains a significant cause of foodborne illnesses. A variety of natural and synthetic compounds have been studied to inhibit the growth of L. monocytogenes in foods. Antimicrobial combinations with synergistic antilisterial properties can reduce the dose of each antimicrobial, which can be further enhanced by chelating compounds. Therefore, the objective of this study was to determine antilisterial properties of binary or ternary combinations of lactobionic acid (LBA), nisin, and thymol in tryptic soy broth (TSB), 2% reduced-fat milk, and whole milk...

BACKGROUND: The gut microbiota is a reservoir of opportunistic pathogens that can cause life-threatening infections in critically ill patients during their stay in an intensive care unit (ICU). To suppress gut colonization with opportunistic pathogens, a prophylactic antibiotic regimen, termed "selective decontamination of the digestive tract" (SDD), is used in some countries where it improves clinical outcome in ICU patients. Yet, the impact of ICU hospitalization and SDD on the gut microbiota remains largely unknown...

Systemic fungal infections represent an important public health concern, and new antifungal agents are highly desirable. Herein, we describe the design, synthesis and biological evaluation of a novel class of antifungal compounds called Antibody-Recruiting Molecules targeting Fungi (ARM-Fs). Our approach relies on the use of non-peptidic small molecules, which selectively bind fungal cells and recruit endogenous antibodies to their surfaces, resulting in immune-mediated clearance. Using the opportunistic fungal pathogen Candida albicans as a model, we identified a highly specific bifunctional molecule able to mediate the engulfment and phagocytosis of C...

Newborn screening for severe combined immunodeficiency has proven successful in identifying infants with T-cell deficiencies before they become severely ill. Additionally, the newborn screen can detect subtle early phenotypes that may become severe later in life. We present the case of siblings with features suggestive of T-cell lymphopenia identified as having low T-cell receptor excision circles counts by newborn screening. Expanded immune testing showed robust lymphocyte mitogen and antigen responses with normal vaccine responses and immunoglobulin levels for both boys over time...

The gastrointestinal microbiome is crucial in human health. With greater than 10 times the cell count of an individual, the gastrointestinal microbiome provides many benefits to the host. It plays an important role in chronic illnesses and immune diseases and also following burns and trauma. This study aimed to determine whether severe burns affect the gastrointestinal microbiome during the early stages of after burn injury and the extent to which the microbiome is disturbed by such burns. We used a rat burn model to investigate any changes occurring in the microbiome after the burn trauma using 16S rRNA sequencing and downstream α-diversity, β-diversity, and taxonomy analysis...

BACKGROUND: Toxoplasma gondii, a common opportunistic protozoan, is a leading cause of illness and mortality among immunosuppressed individuals and during congenital infections. Current therapeutic strategies for toxoplasmosis are not fully effective at curtailing disease progression in these cases. Given the parasite ability to influence host immunity and metabolism, understanding of the metabolic alterations in the host's immune organs during T. gondii infection may enhance the understanding of the molecular mechanisms that define the pathophysiology of T...

Cronobacter (C.) sakazakii is an opportunistic pathogen and has been associated with serious infections with high mortality rates predominantly in pre-term, low-birth weight and/or immune compromised neonates and infants. Infections have been epidemiologically linked to consumption of intrinsically and extrinsically contaminated lots of reconstituted powdered infant formula (PIF), thus contamination of such products is a challenging task for the PIF producing industry. We present the draft genome of C. sakazakii H322, a highly persistent sequence type (ST) 83, clonal complex (CC) 65, serotype O:7 strain obtained from a batch of non-released contaminated PIF product...

Invasive aspergillosis is an important cause of morbidity and mortality among immunocompromised patients. Prolonged neutropenia is the most common risk factor. It has rarely been reported to occur in non-neutropenic critically ill patients in the intensive care unit setting. Mortality rate in this group has been reported to be as high as 92%. We report a case of tracheobronchial aspergillosis in a non-neutropenic critically ill patient to highlight the fact that critically ill patients admitted in the intensive care unit can develop opportunistic infections such as invasive aspergillosis even in the absence of classic risk factors and prior history of immunosuppression...

BACKGROUND: Cryptococcus neoformans is frequently present as an opportunistic pathogen mainly affecting immunocompromised populations. Disseminated C. neoformans infection in immunocompetent population is rare and usually involves lung and central nerve system. Cryptococcus from biologic samples can easily grow on routine fungal and bacterial culture media. Besides, cryptococcal latex agglutination test has been established as a reliable diagnostic tool with overall sensitivities of 93-100%...

Inflammatory bowel disease (IBD) is a devastating disease that is associated with excessive inflammation in the intestinal tract in genetically susceptible individuals and potentially triggered by microbial dysbiosis. This illness markedly predisposes patients to thrombophilia and chronic debility as well as bowel, lymphatic, and liver cancers. Development of new therapies is needed to re-establish long-term immune tolerance in IBD patients without increasing the risk of opportunistic infections and cancer...

Alcohol and other drug (AOD) use is common in our society. The use of these substances flow throughout all areas of healthcare, and is especially prevalent in patients presenting to the emergency department with signs of mental illness. At the extreme end of these presentations patients present involuntarily with either police or ambulance officers. The aim of this study was to identify and describe the population presenting to the ED involuntarily with and without substance misuse as a precipitating factor...

Herein we investigated the intestinal carriage of α-toxigenic and enterotoxigenic Clostridium perfringens during infancy, focusing on its association with other gut microbes and mode of delivery and feeding. Faecal samples from 89 healthy term infants were collected at age 7 days, 1 month, 3 months, 6 months and 3 years. C. perfringens was quantified by qPCR; other gut bacteria were quantified by reverse-transcription-qPCR. Alpha-toxigenic C. perfringens was detected in 3.4% infants at day 7 but was present in 35-40% infants at subsequent time-points, with counts ranging from 10(3)-10(7) cells/g faeces...

Cronobacter spp. are emerging infectious bacteria that can cause acute meningitis and necrotizing enterocolitis in neonatal and immunocompromised individuals. Although this opportunistic human-pathogenic microorganism has been isolated from a wide variety of food and environmental samples, it has been primarily linked to foodborne outbreaks associated with powdered infant formula. The U.S. Food and Drug Administration use the presence of these microbes as one of the criteria to assess food adulteration and to implement regulatory actions...
