Background. Hospital-acquired infections have remained a serious cause of mortality, morbidity, and extended hospitalization. Bacterial contamination of inanimate surfaces of the hospital environment and equipment is considered a major contributing factor to the development of several nosocomial infections worldwide. The hospital environment and many devices are an important reservoir of many clinically important bacterial agents including multidrug-resistant pathogens. Therefore, this systematic review and meta-analysis are aimed at investigating bacterial pathogens and their antimicrobial resistance patterns of inanimate surfaces and equipment in Ethiopia. Methods. An exhaustive literature search was carried out using the major electronic databases including PubMed, Web of Science, MEDLINE, EMBASE, CINAHL, Google Scholar, Cochrane Library, Scopus, and Wiley online library to identify potentially relevant studies without date restriction. Original articles which address the research question were identified, screened, and included using the PRISMA flow diagram. Data extraction was prepared in Microsoft Excel, and data quality was assessed by using 9-point Joanna Briggs Institute critical appraisal tools. Then, data were exported to STATA 16.0 software for analyses of pooled estimation of outcome measures. Estimation of outcome measures at a 95% confidence interval was performed using DerSimonian-Laird’s random-effects model. Finally, results were presented via text, figures, and tables. Results. A total of 18 studies with 3058 bacterial isolates recovered from 3423 swab specimens were included for systematic review and meta-analysis. The pooled prevalence of bacterial contamination of inanimate surfaces and equipment was found 70% (95% CI: 59, 82). Among the Gram-negative bacterial species, the prevalence of ampicillin-resistant K. pneumoniae was the highest 80% (95% CI: 78, 92) followed by Citrobacter species 78% (95% CI: 57, 83). Conclusion. This study has shown a high prevalence of bacterial contamination of inanimate surfaces and equipment in Ethiopia.

Hydroxylated Metabolite

Aflatoxin M1 (AFM1) as a 4-hydroxylated metabolite of carcinogenic mycotoxin Aflatoxin B1 (AFB1) is considered as an acute toxic compound found in milk and its derived products (1). Regarding the critical public health issue induced by AFM1 and as milk is essential in human food chain, its maximum limit has been set by regulatory agencies considering the economic status and development of the countries (4). The maximum permissible limit for AFM1 is 50 ng/kg (different countries including European Union (EU) members) to 100 ng/kg (different countries including USA) (5). In Iran, it has been regulated as 100 ng/kg (6). To the best of our knowledge, there is several similar systematic review and meta-analysis about the contamination of campylobacter in milk, globally and specifically in Iran (4, 5, 7-10). However, we will try to examine the mean and prevalence of AFM1 in different type of milk (cow, sheep, goat, raw, processed) in different region of Iran with long time interval (1974-2021). Moreover, more general and specific databases and grey literature with excellent eligibility criteria will be applied to have a more comprehensive review leading to an interesting finding by techniques such as risk of bias assessment (for assessing quality of included studies), publication bias assessment, finding the source of heterogeneity by sub-group analysis in addition to meta-analysis process.

Background: Cockroaches have been compromised with the human environment posing some risks to humans. Objective: A systematic review and meta-analysis study about the bacterial contamination of cockroaches in the human dwelling environmentswere investigated. Methodology: Relevant topics about bacterial contamination of cockroaches were collected from scientific websites between January 2016 and January 2017. After a preliminary review 32 of the collected topics were selected to become part of the detailed synthesis meta-analysis review. Results: Results showed that the global mean bacterial contamination trend of cockroaches and Periplaneta americana ranged 45.0-80.0 and 55.0-75.0 %, respectively which were increased while it were 90.0-50.0 % for Blattella germanica which decreased in recent years. The global mean bacterial contamination of cockroaches, P. americana and B. germanica was also 67.9, 72.9 and 62.9 %, respectively which P. Americana had the most global mean bacterial contamination. Statistical analysis didn’t show any significant differences between any combination of bacterial contamination of the cockroaches, and P. americana and B. germanica surfaces such as totalexternal, total-internal and external-internal; any type environment of cockroaches, P. americana and B. germanica including households, hospitals and miscellaneous; any combination of bacterial contamination such as between total-total, external-external and internal-internal surfaces of the P. americana and B. germanica; and P. americana and B. germanica in combination environments of households-households, hospitals-hospitals and miscellaneous-miscellaneous (P > 0.05). Conclusions: The external and internal surfaces of any type cockroach have equal importance ofbacterial contamination and they threaten human health in the any type environment.
