Quantitative meta-analysis using STATA-14 (metaprop command) was performed. Occupational exposure to human Mycobacterium bovis infection: A - PLOS Two independent reviewers (HT and SB) performed full-text review and excluded articles based on specific requirements, which are listed in the PRISMA flow chart (Figure 1). The findings in this report are subject to at least four limitations. NIHMS1737556-supplement-Supporting_Information_1.docx, NIHMS1737556-supplement-Supporting_Information_2.docx, To determine the distribution of MTBC species, Investigating molecular Epidemiology of MTBC species, To identify and molecularly characterize the MTBC strains, To analyse the epidemiologic distribution, of the MTBC strains, To investigate the transmission of TB between farmers and their cattle, To determine the factors associated with M. bovis disease, To analysed spatial distribution of MTBC lineages, It was part of a major project focused on molecular and clinical epidemiology in a pastoral community, Focused on area with highest livestock population density in the country, PCR amplification differentiate two of the four, Targeted high-risk individuals who had close contact with livestock. To prevent outbreaks of M. bovis in human populations, . The main etiologic agent of tuberculosis (TB) in livestock and wildlife is Mycobacterium bovis.This species also infects humans through inhalation or ingestion and causes TB that is clinically indistinguishable from that caused by M. tuberculosis.. Bayraktar B, Bulut E, Bari AB, Toksoy B, Dalgic N, Celikkan C, & Sevgi D (2011). Nevertheless, the highest prevalence was also recorded from studies conducted in Africa (Jenkins et al., 2011; Nuru et al., 2017) (Figure 3). Given that Eggers test indicated as there is a significant small study effect at p-value of p >|t|= 0.000. Regassa Alemayehu, Medhin Girmay, Ameni Gobena (2008). Tuberculosis (TB) caused by Mycobacterium tuberculosis is a leading cause of human deaths due to any infectious disease worldwide. Public health responses to M. bovis pulmonary TB should be the same as those for M. tuberculosis TB, with additional inquiries about consumption of unpasteurized dairy products. Using the review tables (Table 1a,,b)b) and the first meta-analysis modelling (Figure 2). Spatio-Temporal Distribution of Mycobacterium tuberculosis complex strains in Ghana. The .gov means its official. The prevalence of M. bovis that was identified from human TB cases was deemed the relevant disease condition. Most importantly, the numerator and denominator should be clearly reported, and percentages of identified M. bovis cases should be calculated. The PubMed wordmark and PubMed logo are registered trademarks of the U.S. Department of Health and Human Services (HHS). Average score of two independent reviewers identified 37% (7/19) studies with low risk of bias, 63% (12/19) with moderate risk of bias, and the overall quality score reflected that about 70.8% of assessment criteria were found to be appropriate. This is also similar to that of the previous findings reported more than two decades ago in Europe and USA. In people, M. bovis causes TB disease that can affect the lungs, lymph nodes, and other parts of the body. For example, the specificity of a PCR-based method using primers JB21/22 for identification of M. bovis (see Table 1b) was shown to be low by Sales et al (Sales etal., 2014). Cluster of human tuberculosis caused by. Mycobacterium Steven L. Percival, David W. Williams, inMicrobiology of Waterborne Diseases (Second Edition), 2014 Basic Microbiology Mycobacteriaare Gram-positive, catalase positive, non-motile, non-spore forming rod-shaped bacteria (0.2-0.6 m wide and 1.0-10 m long). Molecular clustering of patients with diabetes and pulmonary tuberculosis: A systematic review and meta-analysis. Those studies were either more concerned on the importance of Zoonotic TB or need to show the performance of the tool while the procedure could not differentiate M. bovis from other MTBC species (Ghariani et al., 2015; Siala et al., 2017). Saving Lives, Protecting People, http://www.cdc.gov/tb/statistics/reports/2014/pdfs/tb-surveillance-2014-report.pdf, http://www.cdc.gov/mmwr/preview/mmwrhtml/rr5415a2.htm, Centers for Disease Control and Prevention, U.S. Department of Health & Human Services, Thoen C, Lobue P, de Kantor I. It includes Mycobacterium bovis which is responsible for zoonotic tuberculosis. Meta-analysis findings of the random model that shows individual study estimates (ES (95% CI)) of genotyping-based studies and subtotal prevalence of Mycobacterium bovis across regions, Meta-analysis findings of the random model that shows individual study estimates (ES (95% CI)) of genotyping-based studies and subtotal prevalence of Mycobacterium bovis with respect to site. Yeboah-Manu D, Asare P, Asante-Poku A, Otchere ID, Osei-Wusu S, Danso E, Forson A, Koram KA, & Gagneux S (2016). As it is described in Table 1a,,b,b, there were two main sources of samples (specimens). (2011), which was the highest M. bovis prevalence identified among included studies that were using genotyping methods (Jenkins et al., 2011). Hlavsa MC, Moonan PK, Cowan LS, et al. Patient Bs eldest sibling and mother, both of whom were born in Mexico, were also infected but neither had active TB disease and thus would not have been infectious. This review summarizes and estimates the prevalence of M. bovis infection among human cases. Further clarification for unclear scores and additional information was sought to solve discrepancies between the two reviewers. Although zoonotic TB is still reported from most continents in the world, it remains challenging to understand the real impact of the disease because of differences in identification methods. MMWR Morb Mortal Wkly Rep 2016;65:197201. Quality of studies and risk of bias were assessed using standard tools for prevalence study reports. After removal of duplicates, three levels of screening based on Title, Abstract and Full-text review were performed. However, a clear trend in prevalence could be found when the typing method was considered all five conventional-based studies reported higher than the average prevalence of zoonotic TB while genotyping-based methods detected lower than the average prevalence of M. bovis (Table 1b). Meta-analysis was performed on 19 included studies, with a total of 7,185 MTBC isolates identified; 702 (9.7%) of them were characterized as of subspecies M. bovis, but there was a large prevalence difference between the studies, ranging from 0.4% to 76.7%. M. tuberculosis is the main causative agent of human TB, and cattle are the primary host of Mycobacterium bovis; due to close interaction between cattle and humans, M. bovis poses a zoonotic risk. Genotyping of Mycobacterium tuberculosis complex isolated from humans Heterogeneity of study findings was assessed by I2 test and managed through subgroup analysis based on study characteristics. Today, reservoirs of Mycobacterium bovis, the causative agent of tuberculosis in animals, and sometimes humans, exist in a range of countries . Mycobacterium bovis : From Genotyping to Genome Sequencing Tuberculosis(TB) is a chronic communicable bacterial disease caused by Mycobacterium tuberculosis complex (MTBC) species. M. tuberculosis is the main causative agent of human TB, and cattle are the primary host of Mycobacterium bovis; due to close interaction between cattle and humans, M. bovis poses a zoonotic risk. et al., 2016). A presumptive diagnosis of TB disease caused by M. bovis was made, and treatment was started in September 2015, based on clinical findings, including a new pulmonary infiltrate (4,6). Strain Diversity ofMycobacterium tuberculosislsolates from Pulmonary Tuberculosis Patients in Afar Pastoral Region of Ethiopia. Mycobacterium bovis at the animal-human interface: A problem, or not? Evaluation of the cepheid xpert MTB/RIF assay for direct detection of Mycobacterium tuberculosis complex in respiratory specimens. The overall review approach was done based on condition-context-population (CoCoPop) review method. Dean AS, Forcella S, Olea-Popelka F, Idrissi AE, Glaziou P, Benyahia A, Mumford E, Erlacher-Vindel E, Gifford G, Lubroth J, Raviglione M, & Fujiwara P (2018). Torres-Gonzalez P, Soberanis-Ramos O, Martinez-Gamboa A, Chavez-Mazari B, Barrios-Herrera MT, Torres-Rojas M, Cruz-Hervert LP, Garcia-Garcia L, Singh M, Gonzalez-Aguirre A, Ponce de Leon-Garduo A, Sifuentes-Osornio J, & Bobadilla-del-Valle M (2013). Midway through the investigation, after M. bovis was recognized as the causative agent, contacts who had positive test results were also asked about travel abroad and consumption of unpasteurized dairy products from Mexico. Accessibility Funnel plots of standard error and precision used to assess any publication bias. The only social connection between patients A and B was regular attendance at the same church. The publisher's final edited version of this article is available at, GUID:CB23263B-EFDA-452D-B20D-1C11282DEEEE, GUID:8278C487-BAB0-49D5-AAC5-4825DB39F5CE, Biochemical tests and Pyrazinamidase deamidation (P). A roadmap for zoonotic tuberculosis: A One Health approach to ending tuberculosis. Zoonoses Public Health. we compared the methodological differences and the M. bovis prevalence reported by these studies, which varied in the use of genotyping and conventional identification techniques. Mycobacterium Bovis Infection in Animals and Humans This investigation illustrates typical challenges of investigating human M. bovis infections. Careers. Cleaveland S, Shaw DJ, Mfinanga SG, Shirima G, Kazwala RR, Eblate E, Sharp M (2007). Essentially, spoligotyping was the most common procedure. In recent years, M. bovis infections have been detected sporadically among Nebraska beef herds (late 1990s, 2005, 2009, and 2013) and an elk herd (2009) (Nebraska Department of Agriculture, unpublished data, June 29, 2015). It is related to Mycobacterium tuberculosis, the bacterium which causes tuberculosis in humans. Animal tuberculosis (TB), caused by Mycobacterium bovis, is maintained in Portugal in a multi-host system, with cattle, red deer and wild boar, playing a central role.
