    Droplets generated from toilets during urination as a possible vehicle of carbapenem-resistant Klebsiella pneumoniae

    BACKGROUND: In the health care setting, infection control actions are fundamental for containing the dissemination of multidrug-resistant bacteria (MDR). Carbapenemase-producing Enterobacterales (CPE), especially Klebsiella pneumoniae (CR-KP), can spread among patients, although the dynamics of transmission are not fully known. Since CR-KP is present in wastewater and microorganisms are not completely removed from the toilet bowl by flushing, the risk of transmission in settings where toilets are shared should be addressed. We investigated whether urinating generates droplets that can be a vehicle for bacteria and explored the use of an innovative foam to control and eliminate this phenomenon. METHODS: To study droplet formation during urination, we set up an experiment in which different geometrical configurations of toilets could be reproduced and customized. To demonstrate that droplets can mobilize bacteria from the toilet bowl, a standard ceramic toilet was contaminated with a KPC-producing Klebsiella pneumoniae ST101 isolate. Then, we reproduced urination and attached culture dishes to the bottom of the toilet lid for bacterial colony recovery with and without foam. RESULTS: Rebound droplets invariably formed, irrespective of the geometrical configuration of the toilet. In microbiological experiments, we demonstrated that bacteria are always mobilized from the toilet bowl (mean value: 0.11 ± 0.05 CFU/cm2) and showed that a specific foam layer can completely suppress mobilization. CONCLUSIONS: Our study demonstrated that droplets generated from toilets during urination can be a hidden source of CR-KP transmission in settings where toilets are shared among colonized and noncolonized patients

    This report is about an innovation of a toilet brush. In this era especially with the pandemic covid-19 outbreak, people always care about cleanliness of a toilet, be it at home or the public toilet. In order to make sure they used only the clean and germ-free toilet, they need to care about the hygiene. Different from the existing toilet brush, this new product has come out with the electric toilet brush with disinfectant holder, named Cleanzee toilet brush. Cleanzee toilet brush is a smart electronic toilet brush that is cordless and powered by 2 D batteries that can last up to 3 hours of usage per day. The brush bristles are made of silicone which is a very flexible material that will make it easier to reach and slide to the curvy area of every toilet bowl. The brush also comes with a chemical dispenser so that user can directly sprays the chemical from the brush handle and clean the toilet bowl instantly. Other than that, the brush also comes with a disinfectant holder where it disinfects while holds the brush steadily and it then can be safely placed anywhere around the toilet. Cleanzee toilet brush is the product that has been targeted some group of people such as household managers, usually housewives or maids and cleaning services company. By purchasing this product, the toilet cleaning chores will be easy, effortless and efficient. This is because the Cleanzee toilet brush not only cleans and scrub the toilet bowl automatically, it also disinfects the brush after usage so that the brush is hygienic and safe to be used next time

    Isolation and characterization of gram negative bacteria that may cause UTI from student toilets in UiTM Kuala Pilah / Nooradila Anzeli

    In general, most of gram negative bacteria known as pathogenic and may spread due to the lack hygiene of the toilet. This problem can develop into serious illness like urinary tract infection (UTI). By using a sterile cotton swab, swabbing method was performed to swab different part of the toilet surface include of bowl, floor and seat. Samples were inoculated first on Nutrient agar before re-inoculated on MacConkey and Blood agar. All the samples were incubated at 37oC for 24 hours. Biochemical tests such as catalase, oxidase, IMViC and TSI proceed for bacterial identification. Results showed gram negative bacteria which are E.coli, Pseudomonas spp. and Klebsiella spp. were isolated from the students’ toilets. The result of this study indicates high presence of gram negative bacteria on students’ toilet in UiTM Kuala Pilah

    Delayed Inhalational Injury due to Accidental Muriatic Acid Poisoning

    Get PDF
    Muriatic acid is the commonly used toilet bowl cleaner in India. It is delivered industrially and is utilized for cleaning, pickling, electroplating metals, in refining mineral metals, in petrol well extraction, in cowhide tanning, in the refining of fats, cleansers, and consumable oils. Inhalation is the most common exposure of muriatic acid contamination. In this article, medical studies about a case of delayed inhalational injury due to muriatic acid poisoning has been reported

    A mixed-methods study on toilet hygiene practices among Chinese in Hong Kong.

    Get PDF
    BACKGROUND: Public toilets are a common transmission vector of infectious diseases due to environmental contamination. Research on Chinese people's hygiene practices in public lavatories are lacking. This study examined Chinese people's hygiene practices in public lavatories in Hong Kong. METHODS: We conducted qualitative interviews and a self-administered questionnaire survey with local residents from June 2016 to April 2018. Four focus group discussions and three individual interviews informed the design of the questionnaire. We recruited interviewees and survey respondents via social service centers. The interviews and questionnaire focused on the public's daily practices and hygiene behaviors in public toilets. Content analysis of qualitative data was conducted. Multivariable logistic regressions were used to examine the association between age and toilet hygiene behaviors. RESULTS: Our qualitative component revealed a range of handwashing practices, from not washing at all, washing without soap, to washing for a longer time than instructions. Other toilet use practices were identified, such as not covering toilet lid before flushing and stepping on toilet seats due to dirtiness, and spitting into toilet bowls or hand basin. Totally, 300 respondents completed the questionnaire. Among them, 212 (70.9%) were female and 246 (86.1%) were aged 65 or below. More than two thirds always washed hands with soap (68.7%) and dried hands with paper towels (68.4%). Up to 16.2% reported stepping on toilet seats and 43.9% never covered the toilet lid before flushing. Over one fourth (26.4%) spit into squat toilets/ toilet bowl. Regression analyses showed that the elderly group were less likely to report stepping on toilet seats (adjusted odds ratio, AOR = 0.17, 95%CI 0.03-0.88), flushing with the toilet lid closed (AOR = 0.40, 0.16-0.96), but more likely to spit into squat toilets/ toilet bowl (AOR = 4.20, 1.50-11.74). CONCLUSIONS: Hong Kong Chinese's compliance to hygiene practices in public toilets is suboptimal. Stepping on toilet seat is a unique Chinese practice due to the dirtiness of toilet seats. Spitting practices may increase the risk of airborne infectious diseases and need improvement. Measures are needed to improve toilet hygiene behaviors, including public education campaigns and keeping toilet environment clean

    Active End-Effector Pose Selection for Tactile Object Recognition through Monte Carlo Tree Search

    Full text link
    This paper considers the problem of active object recognition using touch only. The focus is on adaptively selecting a sequence of wrist poses that achieves accurate recognition by enclosure grasps. It seeks to minimize the number of touches and maximize recognition confidence. The actions are formulated as wrist poses relative to each other, making the algorithm independent of absolute workspace coordinates. The optimal sequence is approximated by Monte Carlo tree search. We demonstrate results in a physics engine and on a real robot. In the physics engine, most object instances were recognized in at most 16 grasps. On a real robot, our method recognized objects in 2--9 grasps and outperformed a greedy baseline.Comment: Accepted to International Conference on Intelligent Robots and Systems (IROS) 201
