Abstract
Shiga-like toxin-producing Escherichia coli (STEC) is a well-known cause of foodborne acute diarrheic diseases, especially in children and the elderly. The potentially fatal complications associated with toxin production range from bloody diarrhea and ischemic colitis to kidney failure, hemolytic-uremic syndrome (HUS), and colon perforation. Here, we describe a case and literature review of STEC-induced colitis, highlighting the clinical features and the necessary tools for the best diagnostic approach and management. Facing challenging differential diagnosis, ranging from ischemic colitis and inflammatory bowel disease to infectious processes due to a pathogenic or opportunistic agent, we conducted a step-by-step exploration. Following bacteriological investigation, imagistic screening, and colonoscopy, we ruled out some of the initial suppositions and reached a final diagnosis, while also considering the pathological results. Although antibiotics are not indicated in this pathology, our patient did receive antibiotics, given the risk of translocation and colon perforation, without any associated complications such as HUS or peritonitis. Detailed and rigorous investigations conducted by a multi-specialty team are required for prompt medical support. Coping with the symptoms and refraining from further complications are the mainstem aims of treatment.

Microbial Load and Antibiotic Resistance of Escherichia coli and Staphylococcus aureus Isolated from Ready-to-Eat (RTE) Khebab Sold on a University Campus and Its Environs in Ghana. J FOOD QUALITY 2021.

Abstract
The demand for ready-to-eat (RTE) foods is handy to busy urban dwellers. Handling, processing, and selling are known to contaminate these foods and cause foodborne outbreaks. This study assessed a load of S. aureus and E. coli in khebabs (beef, chevon, and gizzard) sold on the KNUST campus and its environs and how resistant they are to clinically relevant antimicrobial agents. Thirty-six (36) khebab samples were purchased from vendors at Kotei, Ayeduase, Kentinkrono, Boadi, KNUST campus, and Ayigya. They were analyzed for S. aureus and E. coli and their resistance to clinically relevant antimicrobial agents checked using standard methods. S. aureus and E. coli load ranged from 4.09 to 5.96 CFU/g and 1.79 to 6.12 MPN/g in beef, 4.02 to 6.01 CFU/g and 1.99 to 4.44 MPN/g in chevon, and 5.37 to 6.18 CFU/g and 1.79 to 6.10 MPN/g in gizzard khebabs in the different locations. E. coli (n = 27) were multiresistant to ampicillin, tetracycline, gentamicin, cefuroxime, ceftriaxone, cefotaxime, and cotrimoxazole (51.85%) and susceptible to chloramphenicol (100%). S. aureus (n = 36) isolates were multiresistant to penicillin, tetracycline, flucloxacillin, cefuroxime, ampicillin (97.22%), erythromycin (75%), cotrimoxazole (86.11%), and gentamicin (69.44%). It can therefore be concluded that the majority of khebabs from the KNUST campus and its environs were contaminated with S. aureus and E. coli above the acceptable standard limits (≤4 log10 CFU/g and ˂2 log10MPN/g, respectively). Also, the S. aureus and E. coli isolated were multiresistant to the antibiotics tested and could be a medium for the transmission of antibiotic-resistant bacteria and therefore expose consumers to a high risk of contracting foodborne infections with drug-resistant strains.

Prevalence, antimicrobial resistance, and genotyping of Shiga toxin-producing Escherichia coli in foods of cattle origin, diarrheic cattle, and diarrheic humans in Egypt. Gut Pathog 2021; 13:8. [PMID: 33546735 PMCID: PMC7863457 DOI: 10.1186/s13099-021-00402-y] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/03/2020] [Accepted: 01/28/2021] [Indexed: 02/07/2023] Open
Abstract
Shiga toxin-producing Escherichia coli (STEC) is a pathotype of E. coli that causes enteric and systemic diseases ranging from diarrhoea to severe hemorrhagic colitis (HC) and hemolytic uremic syndrome (HUS). The emergence of multidrug-resistant (MDR) STEC from cattle sources has increased public health risk and limited treatment options. The prevalence of STEC was investigated in 200 raw food samples (milk and beef samples) and 200 diarrheic samples (cattle and human samples) in a matched region. The presence of stx genes (stx1 and stx2), carbapenemase-encoding genes (blaVIM, blaNDM-1, and blaIMP), and extended-spectrum β-lactamase (ESBL)-encoding genes (blaTEM group, blaCTX-M1 group, and blaOXA-1 group) was screened by polymerase chain reaction (PCR). Antibiogram and Enterobacterial repetitive intergenic consensus (ERIC)-PCR were also conducted. STEC isolates were identified in 6.5% (13/200) of food samples [6% (6/100) of milk and 7% (7/100) of beef samples] and in 11% (22/200) of diarrheic cases [12% (12/100) of cattle and 10% (10/100) of human samples]. We found that O26 (4.5%, 18/400) and O111 (1.5%, 6/400) were the most prevalent STEC serovars and were found more commonly in diarrheic samples. STEC strains with both stx genes, stx2 only, and stx1 only genotypes were present in 62.9% (22/35), 20% (7/35), and 17.1% (6/35) of isolates, respectively. Carbapenemase-producing STEC (CP STEC) isolates were found in 1.8% (7/400) of samples [0.5% (1/200) of foods and 3% (6/200) of diarrheic cases]. The blaVIM gene was detected in all CP STEC isolates, and one human isolate carried the blaNDM-1 gene. ESBL-producing STEC strains were detected in 4.3% (17/400) of samples [1.5% (3/200) of food samples and 7% (14/200) of diarrheic cases]. The blaTEM, blaCTX-M1, and blaOXA-1 genes were detected in 42.9% (15/35), 28.6% (10/35), and 2.9% (1/35) of STEC isolates, respectively. Approximately half (51.4%, 18/35) of STEC isolates were MDR STEC; all CP STEC and ESBL-producing STEC were also MDR STEC. The highest antimicrobial resistance rates were found against nalidixic acid (51.4%) and ampicillin (48.6%), whereas the lowest rates were reported against gentamicin (5.7%) and ciprofloxacin (11.4%). MDR STEC strains were 5.3 times more likely to be found in diarrheic cases than in foods (P = 0.009, 95% CI 1.5-18.7). ERIC-PCR was used for genotyping STEC isolates into 27 different ERIC-types (ETs) with a discrimination index of 0.979. Five ETs showed clusters of 2-4 identical isolates that shared the same virulence and antibiotic resistance genetic profile. Human isolates matched food isolates in two of these ET clusters (the O26 CP STEC cluster and the O111 STEC cluster), highlighting the potential cross-species zoonotic transmission of these pathogens and/or their genes in the study region. This is the first detection of CP STEC in milk and diarrheic cattle in Egypt.

Abstract
Introduction: Hemolytic uremic syndrome is the most frequent cause of acute renal failure in children, commonly after gastrointestinal infections with E. coli or Salmonella, and it is characterized by progressive renal failure associated with microangiopathic hemolytic anemia and thrombocytopenia. Cardiac involvement is frequently encountered and can be potentially fatal in hemolytic uremic syndrome. It is usually determined by overhydration, hypertension, anemia, diselectrolytemia, acid-base disorders and tendency to form thrombi, and it consists in the following conditions: pericarditis, myocardial infarction, dilated cardiomyopathy, cardiac failure, and arrythmias. Objective: The aim of this study is to observe the incidence of cardiovascular complications in children with acute hemolytic uremic syndrome, underline which are the most useful tools in establishing an accurate diagnosis, and discover the treatment protocol that has the most powerful impact upon the cardiovascular manifestations. Materials and methods: We studied a number of 50 children who checked in the Nephrology Department of "M. S. Curie" Emergency Clinical Hospital in Bucharest, Romania, between January 2016 and August 2020. We performed the clinical examination of all patients as well as several paraclinical tests such as electrocardiogram, transthoracic echocardiography, arterial blood pressure monitorization, and vascular Doppler ultrasound. Patients included in the study were aged between five and 40 months. Discussion and results: The majority of these children were diagnosed with arterial hypertension and some of them with cardiac failure and profound venous thrombosis. Transthoracic echocardiography revealed pathological aspects such as left ventricular hypertrophy, diastolic dysfunction, systolic dysfunction of the left ventricle, mitral regurgitation, aortic regurgitation, and pericarditis. Cardiac ultrasound findings were reversible in the majority of patients, most of them being treated with ACE inhibitors (eventually in association with other antihypertensive drugs).
