“…These results agreed with that reported by other researchers in Egypt 2.4%, 1.6%, and 1.8% (22)(23)(24). In contrast, several authors have reported either low prevalence rates 0.9%, 0.13%, 0.96%, and 0.30% (25)(26)(27)(28) or high values 11.6%, 11.3%, and 4.3% (5,7,29). The herd-level prevalence of bovine TB was 68.75%; these results agree with 74.1%, 67%, and 65.8% (8,30,31) and higher than prevalence reported 15%, 40.9%, and 40% (5,29,32).…”

A cross-sectional study was carried out from November, 2015 to April, 2018 to determine the prevalence and identify the risk factors of BTB using the comparative intradermal tuberculin (CIDT) test on 5327 dairy cattle in 16 dairy herds in mid-delta, Alexandria Road and Upper Egypt districts. Questionnaires used to collect data on herd size and management. The herd and individual animal prevalence at cut-off ≥4mm were 68.75% (95%, CI: 46 to 91.4) and1.67% (95%, CI: 1.3to 2.1) respectively. The individual prevalence was significantly associated with age, breed and different location of farms and density of cattle in yard. On herd level, history of BTB in the farm, management practices, raising of different species in the same facility and newly purchased cattle are important risk factors for BTB. The postmortem examination of positive reactors revealed 66 (85.71%) out of 77slaughtered cattle with visible lesions and 11(14.29%) with non-visible lesions. Bacteriological examination revealed 74.24% (49/66) from visible lesions and 9.09% (1/11) from non-visible lesions were Mycobacterium bovis. The indirect enzyme linked immunosorbent assay (IELISA) results revealed 31(40.26%) showed positive result including 29 (93.6%) visible lesions and 2(6.4%) nonvisible lesions. In conclusion, the prevalence high in herds with poor management condition, raised different species in the same facility, had previous history of BTB infection and purchased new animals. At animal level Holstein breed, 3-6 years age, kept in high density and located in mid-delta district were at higher risk to be reactor to comparative intradermal tuberculin (CIDT) test.

“…The total recovery rate of M. bovis for both visible and nonvisible reactors was 50 (64.93%), these results agreed with (22,24,53,54). and the number of atypical mycobacteria isolates was 3 (3.9%) which agree with (26,54).…”

“…2 Depending on the region, the prevalence of bovine TB can range from 0.1% to 50%; there were 140,000 new cases in 2019, with most animals slaughtered upon discovery of an infection. [3][4][5][6][7] The increasing proximity between humans, livestock and wildlife, and its role in the transmission dynamics of mycobacterial infections, necessitates the need for a One Health approach in tackling TB infections. The One Health approach is an integrated multidisciplinary approach to attain optimal health for humans, animals and the environment in the surveillance of zoonotic diseases such as TB.…”

Substandard and falsified (SF) medicines are a global health challenge with the World Health Organization (WHO) estimating that 1 in 10 of medicines in low- and middle-income countries (LMICs) are SF. Antimicrobials (i.e. antimalarials, antibiotics) are the most commonly reported SF medicines. SF medicines contribute significantly to the global burden of infectious diseases and antimicrobial resistance (AMR). This article discusses the challenges associated with the global impact of SF and unregistered/unlicensed antimicrobials with a focus on anti-TB medicines. Tuberculosis (TB) is the 13th leading cause of death worldwide, and is currently the second leading cause of death from a single infectious agent, ranking after COVID-19 and above HIV/AIDS. Specifically in the case of TB, poor quality of anti-TB medicines is among the drivers of the emergence of drug-resistant TB pathogens. In this article, we highlight and discuss challenges including the emergence of SF associated AMR, patient mistrust and lack of relevant data. We also present study reports to inform meaningful change. Recommended solutions involve the adaptation of interventions from high-income countries (HICs) to LMICS, the need for improvement in the uptake of medication authentication tools in LMICs, increased stewardship, and the need for global and regional multidisciplinary legal and policy cooperation, resulting in improved legal sanctions.

“…Bovine tuberculosis (BTB) is a chronic, debilitating bacterial disease caused by Mycobacterium bovis (M. bovis) that infects cattle, other animals, and humans. The most common method of disease transmission in animals is through inhalation of infectious droplets in the air, though the bacteria could be consumed through contaminated feed (Liu et al 2019). Although cattle are thought to be the primary hosts of Mycobacterium bovis, isolates have been made from a variety of other livestock and wildlife species, raising public health concerns about the possibility of human transmission (El-Sayed et al…”

Cross-sectional study was conducted from October 2021 to August 2022, to investigate the prevalence and associated risk factors of bovine tuberculosis in cattle in selected districts of Fafan zone. The prevalence was 11.24% (95% CI, 8.61–14.35) and 43.3% (95% CI, 33.27–53.75) at individual and herd level respectively. There were statistically significant differences in proportions of positive reactor animals among body condition score (χ2 = 47.9, P = 0.000), Age (χ2 = 6.0937, P = 0.048), Seasonal migration (χ2 = 4.320, P = 0.038), parity number (χ2 = 10.62, P = 0.005), reproductive status (χ2 = 4.36, P = 0.037). Multivariable logistic regression analysis showed that animal with poor body condition score was more likely to react positive than those in good body condition score adjusted (OR = 0.163; CI = 0.0679 -0.390). Moreover, seasonally migrating cattle had 2.787 times the odds of being tuberculin reactors compared with those non migrating cattle (adjusted OR = 2.787; CI = 1.221–6.358). According to questionnaire, 14.2% (17 of 120) and 13.3% (16 of 120) of the respondents were knowledgeable about bovine tuberculosis and its transmission from animal to human and vice versa, respectively. The general judgment of herders' understanding of BTB transmission methods to humans was very low. This finding provides relatively high prevalence of BTB in cattle at the study area and highlights the need for a practicable control strategy of the disease in the region.
