“…This outcome must only be consistent with the significant consumer demand throughout the holiday seasons and during family gatherings, which take place during the spring and summer seasons. Our results concurred with earlier findings from several Algerian localities [ 1 , 8 , 26 ]. Since bacillus has a long incubation period, the influence of seasonality, as a risk factor, is often debatable since it might delay the specific lesions of bTB at any time of the year [ 30 , 45 ].…”

“…As for the influence of animal gender, females seem to be more susceptible. Similar findings have been reported by several authors [ 1 , 8 , 16 , 26 ]. In another study, the prevalence of diagnosed tuberculosis in slaughterhouses was higher in females than in males (16.3 vs. 7.3 cases/100,000, respectively) [ 49 ].…”

“…The rate of bovine tuberculosis calculated in our study was nearly similar to that recorded previously in the Bejaia area [ 16 ]. However, many studies in Algeria reported higher cattle bTB prevalence rates than in our data [ 1 , 5 , 8 , 26 ]. Likewise, the prevalence rate reported in the present study was lower than those obtained in previous studies conducted in Morocco (3.7% and 4.6%) [ 29 , 30 ], and Tunisia (3.39%) [ 31 ].…”

Tuberculosis (TB) is considered one of the most widespread and devastating zoonotic diseases in low-income countries, with a cosmopolitan distribution. The aim of this 10-year retrospective survey (from 2011 to 2020) was to determine the frequency of bovine, ovine, and goat tuberculosis in different local slaughterhouses across Constantine Province, Algeria. The control of livestock carcasses was systematically performed by veterinarian inspectors, after each stage of the slaughter process. The routine abattoir inspection included the detection of visible abnormalities on different organs and lymph nodes. The overall prevalence of tuberculosis recorded in slaughtered animals was 0.83%, with the following distribution among species: 2.73% in cattle, 0.001% in sheep, and 0.0% in goats. During the study period, there was a strong correlation (R = 0.82) (p < 0.01) between tuberculosis occurrence and the number of slaughtered cattle. Fluctuations in monthly TB prevalence ranged from 2% to 24.8% between 2018 and 2020, although there were no statistically significant correlations between infection and the age or gender of the animals, except for the year 2020 when a significantly higher (p = 0.017) percentage of TB cases were recorded in female cattle compared to male cattle. The average monthly weight of the confiscated livers and lungs ranged significantly (p ≤ 0.05) from 150 kg to 350 kg. The study results provide baseline data regarding livestock tuberculosis monitoring in the area of Constantine, Algeria, indicating that the disease incidence is not highly alarming, yet remains a serious public and animal health issue in the screened region.

“…However, based on these assays, the prevalence of BTB among cattle varied significantly according to the population size and country in the MENA region. In large studies, the prevalence was relatively low, ranging between 0.1 [ 32 ] and 16.4% [ 33 ] in Egypt, 4.4 [ 34 ] and 24.2% [ 35 ] in Iraq, 3.5% [ 36 ] in Algeria, and 1.4% [ 37 ] in Turkey. In contrast, a higher prevalence was reported in studies with small population sizes, ranging from 22.2% [ 38 ] to 82.6% [ 39 ] in Egypt, 75% [ 40 ] in Iraq, and 48% [ 41 ] in Tunisia ( Table 1 ).…”

Mycobacterium bovis is the etiologic agent of bovine tuberculosis (BTB), a serious infectious disease in both humans and animals. BTB is a zoonotic disease primarily affecting cattle and occasionally humans infected through close contact with infected hosts or the consumption of unpasteurized dairy products. Zoonotic tuberculosis is strongly associated with poverty and poor hygiene, and low- and middle-income countries bear the brunt of the disease. BTB has been increasingly recognized as a growing public health threat in developing countries. However, the lack of effective surveillance programs in many of these countries poses a barrier to accurately determining the true burden of this disease. Additionally, the control of BTB is threatened by the emergence of drug-resistant strains that affect the effectiveness of current treatment regimens. Here, we analyzed current trends in the epidemiology of the disease as well as the antimicrobial susceptibility patterns of M. bovis in the Middle East and North Africa (MENA) region, a region that includes several developing countries. Following PRISMA guidelines, a total of 90 studies conducted in the MENA region were selected. Our findings revealed that the prevalence of BTB among humans and cattle varied significantly according to the population size and country in the MENA region. Most of the available studies were based on culture and/or PCR strategies and were published without including data on antimicrobial resistance and molecular typing. Our findings highlighted the paramount need for the use of appropriate diagnostic tools and the implementation of sustainable control measures, especially at the human/animal interface, in the MENA region.
