Objective To discuss the impact of COVID‐19 on global health, particularly on urological practice and to review some of the available recommendations reported in the literature. Material and Methods In the current narrative review the PubMed database was searched to identify all the related reports discussing the impact of COVID‐19 on the urological field. Results The COVID‐19 pandemic is the latest and biggest global health threat. Medical and surgical priorities have changed dramatically to cope with the current challenge. These changes include postponements of all elective outpatient visits and surgical procedures to save facilities and resources for urgent cases and patients with COVID‐19 patients. This review discuss some of the related changes in urology. Conclusions Over the coming weeks, healthcare workers including urologists will be facing increasingly difficult challenges, and consequently, they should adopt triage strategy to avoid wasting of medical resources and they should endorse sufficient protection policies to guard against infection when dealing with COVID‐19 patients.

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.

This study investigated the frequency of carbapenem and colistin resistance in ESBL-producing K. pneumoniae (ESBLK) isolates recovered from chickens and their environment, contact farm workers and hospitalized patients in Egypt. Further, the phenotypic and genotypic relationships between the community and hospital-acquired K. pneumoniae isolates in the same geographical area were investigated. From 272 total samples, 37 (13.6%) K. pneumoniae isolates were identified, of which 20 (54.1%) were hypervirulent. All isolates (100%) were multidrug-resistant (MDR) with multiple antibiotic resistance (MAR) indices ranging from 0.19 to 0.94. Colistin-resistant isolates (18.9%) displayed colistin MIC values >2 μg/mL, all harbored the mcr-1 gene. All isolates from patients (13/90, 14.4%), workers (5/22, 22.7%), chickens (9/100, 9%) and the environment (10/60, 16.7%) harbored a single or multiple β-lactamase genes, blaSHV, blaTEM, blaCTX-M1 and blaOXA-1, often in combination with carbapenemase genes (blaVIM, blaNDM-1 or blaIMP; 45.9%), the mcr-1 gene (18.9%) or both (13.5%). Enterobacterial repetitive intergenic consensus (ERIC)–PCR genotyping revealed 24 distinct ERIC types (ETs) with a discrimination index of 0.961. Six ETs showed clusters of identical isolates from chicken and human sources. The increased frequency and genetic relatedness of ESBLK and carbapenemase-producing K. pneumoniae (CPK) from chickens and humans pose a public health threat that urge more prudent use of antimicrobials in chicken farms to avoid the propagation and expansion of both ESBLK and CPK from the chicken sources to humans.

Background: As Mobile Phones (MPs) aren’t cleaned routinely and have been touched during patient’s examination, they may become contaminated with hospital pathogens. Objectives: Screen MPs of Health care workers (HCWs) for pathogens and verify the effect of disinfectants in their decontamination. Methods: A questionnaire was submitted by 160 HCWs in Tanta University Hospitals. Samples were taken from their MPs and subjected to pour plate counting before and after disinfection. Standard identification and antibiotic susceptibility of isolates were done. Results: Colony count was greater in MPs used while caring for patients or inside restroom, and was less in regularly cleaned MPs. All tested disinfectants reduced the colony count significantly. Pathogens were isolated from 84.38% of samples and 36.25% of them were Multi-Drug Resistant Organisms (MDROs). Conclusion: Using MPs at critical care areas and restroom may contribute to their contamination with pathogens. Regular disinfection of MPs can reduce this contamination.

Background: Streptococcus mutans play an important role in occurrence of dental caries objective: to compare the clinical and microbiological antibacterial outcomes of Mineral trioxide aggregate (MTA) and Calcium hydroxide cement Ca(OH)2. Methodology: 20 primary molars in 10 children with year’s 5-9 y .For each child one tooth was treated with Ca(OH)2 and the other with MTA. Finally, all the cavities were restored using compomer restorative material, and then microbiological parameters were recorded. Results: MTA treated teeth did not show any clinical sign or symptoms of failure. While three teeth treated with Ca(OH)2 were excluded because of necrosis. Changes in color and consistency of dentin were nearly the same for both groups. Microbiological evaluation showed a decrease in the count of Str. mutans with calcium hydroxide and complete killing of bacteria with MTA. Conclusion: The treatment showed satisfactory results of MTA as it was more potent inhibitor of bacterial-growth than Ca(OH)2
