The prevalence is two to three folds higher in developing countries compared to developed countries. Inanimate objects used by healthcare professionals such as gowns, mobile phones, and stethoscopes are highly prone to bacterial contamination from the healthcare setting. In Ethiopia, there is a paucity of published data on the bacterial profile and susceptibility patterns of an isolates.<\/jats:p>\n<\/jats:sec>\n\nObjective<\/jats:title>\nTo determine the bacterial profile and antimicrobial susceptibility patterns from inanimate objects used by healthcare professionals and associated factors at Debre Markos Comprehensive Specialized Hospital, Northwest Ethiopia.<\/jats:p>\n<\/jats:sec>\n\nMethods<\/jats:title>\nA cross-sectional study was conducted at Debre Markos Comprehensive Specialized Hospital from inanimate objects from April 10, 2023 to June 30, 2023 using simple random sampling technique with lottery method. Socio-demographic data was collected using a structured questionnaire. A swab sample from healthcare professionals\u2019 gowns, mobile phones, and stethoscopes were collected and inoculated onto blood agar, chocolate and MacConkey agar. Isolates were identified and characterized by colony morphology, Gram staining and biochemical tests. Antimicrobial susceptibility testing was performed in all isolates by the disk diffusion technique on Muller Hinton agar according to CLSI, 2022 guidelines. Data was entered into EPI-Data and analyzed using SPSS version 25. Logistic regression model was used. Variables with p-value \u2264 0.25 in bivariable logistic regression was fitted to multivariate logistic regression analysis. A p-value of \u2264 0.05 with 95%CI was considered statistically significant.<\/jats:p>\n<\/jats:sec>\n\nResult<\/jats:title>\nA total of 376 healthcare professionals\u2019 inanimate objects were included from 191 study participants. Overall, 60.1% (226\/376) (95%CI: 55.1\u201365) inanimate objects were contaminated. The proportion of bacterial contamination was (65.1%; 82\/126), (60.3%; 76\/126) and (54.8%; 68\/124) for mobile phones, gowns and stethoscopes, respectively. Staphylococcus aureus<\/jats:italic> was the most frequent isolate accounting (22.1%; 83\/376) followed by Staphylococcus epidermidis<\/jats:italic> (17.0%; 64\/376), Escherichia coli<\/jats:italic> (8.8%; 33\/376) and Pseudomonas aeruginosa<\/jats:italic> (4.9%; 18\/376). Working in gynecology\/ obstetrics wards (AOR: 8.69; 95%CI: 1.09\u201369.41, P<\/jats:italic> = 0.041), did not disinfect mobile phones (AOR: 2.69; 95%CI: 1.15\u20136.25; P<\/jats:italic> = 0.021) and stethoscopes regularly (AOR: 3.06, 95%CI: 1.23\u20137.59; P =<\/jats:italic> 0.016), carry mobile phones with patient care materials (AOR: 2.72; 95%CI: 1.18\u20136.29, P<\/jats:italic> = 0.019) and not taken infection prevention training (AOR:3.91; 95%CI:1.71\u20138.93; P =<\/jats:italic> 0.001) were significantly associated with bacterial contamination.Most Gram-negative bacteria were resistant to ampicillin, trimethoprim-sulfamethoxazole and amoxacilline-clavunic acid, while Gram-positive isolates showed high level of resistant to penicillin. On the other hand, meropenem, for Gram-negative and clindamycin for Gram-positive bacteria showed lower level of resistance. Multidrug resistance among Gram-positive and Gram-negative bacteria were (62.6%; 92\/147) and (75.3%; 64\/85), respectively with over all MDR (67.2%, 156\/232).<\/jats:p>\n<\/jats:sec>\n\nConclusion<\/jats:title>\nInanimate objects commonly used by healthcare professionals are important sources of bacterial contamination. S<\/jats:italic>. aureus<\/jats:italic>, S<\/jats:italic>. epidermidis<\/jats:italic> and E<\/jats:italic>. coli<\/jats:italic> were the predominant isolates. Most Gram-negative bacteria were resistant to ampicillin while Gram-positive isolates showed high level of resistant to penicillin. All healthcare professionals should regularly disinfect their inanimate objects to prevent bacterial colonization and potential spread of infection.<\/jats:p>\n<\/jats:sec>","DOI":"10.1371\/journal.pone.0313474","type":"journal-article","created":{"date-parts":[[2024,11,11]],"date-time":"2024-11-11T18:32:52Z","timestamp":1731349972000},"page":"e0313474","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":4,"title":["Bacterial profile and antimicrobial susceptibility patterns of isolates from inanimate objects used by healthcare professionals at Debre Markos Comprehensive Specialized Hospital, Northwest Ethiopia"],"prefix":"10.1371","volume":"19","author":[{"given":"Senedu","family":"Kindie","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3556-3650","authenticated-orcid":true,"given":"Getachew","family":"Mengistu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-2973-8142","authenticated-orcid":true,"given":"Mulatu","family":"Kassahun","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Abebaw","family":"Admasu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3713-6783","authenticated-orcid":true,"given":"Tebelay","family":"Dilnessa","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"340","published-online":{"date-parts":[[2024,11,11]]},"reference":[{"key":"pone.0313474.ref001","article-title":"Prevention of hospital acquired infections: A practical guid","author":"WHO","journal-title":"2002"},{"key":"pone.0313474.ref002","article-title":"The burden of health care-associated infection worldwide","author":"WHO","year":"2016"},{"key":"pone.0313474.ref003","article-title":"Epidemiology of Healthcare -Associated Infections","author":"U.
