Bovine tuberculosis is an important public health and economic disease in Nigeria. This study reports the prevalence of tuberculosis in cattle slaughtered at the central abattoir in Maiduguri, Nigeria. Post mortem examination of 664 cattle carcasses was done at the abattoir for 6 months. The lesions collected were processed by using NALC-NaOH and subjected to acid-fast staining and microscopy. The overall prevalence of tuberculosis based on gross tubercle lesions in cattle slaughtered at Maiduguri abattoir was 62 (9.3%). Female cattle 43 (16.7%) had significantly (p = 0.0001) higher prevalence of tubercle lesions than male cattle 19 (4.7%). Cattle with thin body condition had 44 (21.2%), optimal body condition 16 (5.8%) and overweight cattle 2 (1.1%). There was significant (p = 0.0001) difference between body condition and occurrence of tubercle lesions. Prevalence of tubercle lesions in adult cattle was 29 (17.7%), young adults (25 (7.8%) and calves 8 (4.3%).  Tubercle lesions were most common in thoracic lymph node and lungs than other organs. The prevalence of tuberculosis by Ziehl-Neelsen microscopy was 6.2% (41/664). There was significant (p=0.0001) differences in the prevalence of tuberculosis by Ziehl-Neelsen microscopy and demographic variable except for breeds. Tubercle lesion is endemic in cattle slaughtered in Maiduguri central abattoir. One Health approach is recommended to prevent zoonotic transmission to humans and economic losses among farmers and butchers.

Bovine tuberculosis results in economic losses in livestock production and poses a risk to public health. This study aimed to characterize the epidemiological status of bovine tuberculosis in adult cows in the state of Goiás, Brazil. The state was divided into three sampling strata, corresponding to different livestock production circuits. A total of 18,659 animals were tested with the comparative cervical tuberculin test (CCT), in 300 randomly sampled bovine herds per stratum. An epidemiological questionnaire was used to identify health and management practices that may be associated with the presence of tuberculosis infection in the herd. In Stratum 1, dominated by beef cattle, no animals reacted to the CCT. In Stratum 2, which covers the main dairy regions of the state, the prevalence was estimated at 8.67% [5.73 to 12.74%] for herds and at 0.9% [0.21 to 1.58%] for animals. In Stratum 3, characterized by a mix of dairy, beef and dual-purpose herds, the prevalence was estimated at 1.00% [0.21 to 2.89] for herds and 0.30% [0.10 to 0.49 %] for animals. The overall prevalence in the state of Goiás was 3.43% [2.20 to 4.67%] for herds and 0.30% [0.10 to 0.49%] for animals. The multiple logistic regression analysis revealed that herd-level risk factors associated with the presence of the bovine tuberculosis are: the location of the herd in Stratum 2 (OR = 12.05 [3.52 to 41.28]) and the number of times a cow is milked per day (OR = 6.27 [2.72 to 14.44]). Regular veterinary care was identified as a protective factor (OR = 0.38 [0.15-0.94]). These results indicate that bovine tuberculosis is endemic in the state; its spatial distribution is heterogeneous with a strong concentration in dairy regions. The most intensive dairy farms are those with the highest risk, which is consistent with what other authors’ found elsewhere in Brazil. The epidemiological information generated by this study provides information for planning of risk-based surveillance actions, and justifies the adoption of free-herd certification programs for bovine tuberculosis in the main dairy regions of Goiás.

The objective of this work was to detect the presence of three main pig respiratory viral agents (porcine rubulavirus [PorPV], porcine circovirus type 2 [PCV-2], and porcine reproductive and respiratory syndrome virus [PRRSV]) in tissues of emaciated piglets from the Baj'o Region (Mexico). Necropsies and histopathological studies of 37 pigs with poor body condition were performed; viruses were detected by molecular biology methods and PCV-2 was further assessed by immunohistochemistry (IHC). Histopathologically, interstitial pneumonia was observed in 25/37 (68%) of the piglets. Also, a varying degree of lymphocyte depletion in lymphoid organs was found in 14/37 (38%) animals. Through polymerase chain reaction (PCR) and/or reverse transcription polymerase chain reaction (RT-PCR), from the 37 pigs, 16 were positive for PCV-2, 18 for PRRSV and 1 for PorPV. In accordance with these results, the infection and/or co-infection with PCV-2 and PRRSV were fairly frequent findings in piglets with poor body condition in Mexico, while the infection by PorPV was apparently negligible. Wasting of post-weaning piglets is a global pig farming problem that causes great economic losses and has been associated with diverse factors: microbial agents, environmental factors, nutritional factors, and management. When the Blue Eye Disease was first reported in Mexico, it was associated with severe wasting in post-weaning piglets. This study demonstrated that this disease does not seem to play such an important role in the wasting as was previously thought.

The article identifies the main pathologies found and estimates the economic losses generated in a slaughterhouse in the Thailand municipality, Pará, during the period from March 2010 to October 2014. 55,169 animals were slaughtered, with total economic losses of R$ 1,221,035.90 and ischemia was the most frequent lesion (41.86%). The most frequent condemnation organs were lungs (48.75%), kidneys (41.66%) and liver (3.61%), which produced economic loss of R$ 76,405.65 (6.26%). Tuberculosis was the main cause of carcass condemnation, responsible for R$ 872,783.64 of economic losses. The bovine tuberculosis control can begin in production, with examinations on the farm to slaughter lines, with careful carcass inspection, as advocated by the National Program for the Control and Eradication of Animal Brucellosis and Tuberculosis (PNCEBT), which increases disease control and minimizes condemnations and economic losses at slaughter.

West Nile virus (WNV) is an important zoonotic flavivirus responsible for mild fever to severe, lethal neuroinvasive disease in humans, horses, birds, and other wildlife species. Since its discovery, WNV has caused multiple human and animal disease outbreaks in all continents, except Antarctica. Infections are associated with economic losses, mainly due to the cost of treatment of infected patients, control programmes, and loss of animals and animal products. The pathogenesis of WNV has been extensively investigated in natural hosts as well as in several animal models, including rodents, lagomorphs, birds, and reptiles. However, most of the proposed pathogenesis hypotheses remain contentious, and much remains to be elucidated. At the same time, the unavailability of specific antiviral treatment or effective and safe vaccines contribute to the perpetuation of the disease and regular occurrence of outbreaks in both endemic and non-endemic areas. Moreover, globalisation and climate change are also important drivers of the emergence and re-emergence of the virus and disease. Here, we give an update of the pathobiology, epidemiology, diagnostics, control, and “One Health” implications of WNV infection and disease.

Reliable Identification

Bovine tuberculosis is a zoonotic disease that not only causes huge economic losses but also poses an important risk for human infection. The definitive identification of a clinical isolate relies on time-consuming, highly specialized and laborious biochemical tests. We have developed a method for the rapid and reliable identification of Mycobacterium bovis and for its simultaneous differentiation from other members of the M. tuberculosis complex. Furthermore, the technique also allowed us to distinguish M. tuberculosis complex members from other Mycobacterial species. The method comprises both a single PCR and a multiplex-PCR and can be confidently applied to samples of both veterinary and human origin.

ABSTRACT: Bovine tuberculosis (bTB) is a zoonosis causing economic losses and public health risks in many countries. The disease diagnosis in live animals is performed by intradermal tuberculin test, which is based on delayed hypersensitivity reactions. As tuberculosis has complex immune response, this test has limitations in sensitivity and specificity. This study sought to test an alternative approach for in vivo diagnosis of bovine tuberculosis, based on real-time polymerase chain reaction (PCR). DNA samples, extracted from nasal swabs of live cows, were used for SYBR® Green real-time PCR, which is able to differentiate between Mycobacterium tuberculosis and Mycobacterium avium complexes. Statistical analysis was performed to compare the results of tuberculin test, the in vivo gold standard bTB diagnosis method, with real-time PCR, thereby determining the specificity and sensitivity of molecular method. Cervical comparative test (CCT) was performed in 238 animals, of which 193 had suitable DNA from nasal swabs for molecular analysis, as indicated by amplification of glyceraldehyde-3-phosphate dehydrogenase (GAPDH) gene, and were included in the study. In total, 25 (10.5%) of the animals were CCT reactive, of which none was positive in the molecular test. Of the 168 CCT negative animals, four were positive for M. tuberculosis complex at real time PCR from nasal swabs. The comparison of these results generated values of sensitivity and specificity of 0% and 97.6%, respectively; moreover, low coefficients of agreement and correlation (-0.029 and -0.049, respectively) between the results obtained with both tests were also observed. This study showed that real-time PCR from nasal swabs is not suitable for in vivo diagnosis of bovine tuberculosis; thus tuberculin skin test is still the best option for this purpose.

ABSTRACT: Cystic echinococcosis is a parasitic infection of worldwide distribution, which, despite causing significant loss of health and money, is still a neglected disease. The present study was performed to determine the prevalence of bovine hydatid disease at Research Centre for the Conservation of Sahiwal Cattle, Jahangirabad, Khanewal, Pakistan. Five hundred bovine serum samples were tested for the detection of bovine Echinococcus antibodies (IgG), using the ELISA kits. Antibodies of bovine Echinococcus were detected in 24.2% cattle. Female cattle showed higher disease prevalence (33.2%) compared to (6.02%) in male cattle. There was positive association between sex of cattle and prevalence (P<0.05). Positive correlation between disease prevalence and age was detected. Younger animals (<3 years old) had lower prevalence value of disease than to older animals (> 3 years old). It is concluded that there is high degree of exposure of cattle to Echinococcus at Research Centre for Conservation of Sahiwal Cattle, Khanewal, Punjab. Measures should be taken to reduce risk of disease to avoid its spread to humans as well as great degree of economic losses.

Bovine Fasciolosis is a vector – borne zoonosis and one of the most neglected tropical diseases that cause huge economic losses and poor animal conditions in Nigeria. The prevalence of Fasciolosis in Cattle slaughtered in the Federal Capital Territory, Abuja was investigated. Faecal samples were collected from the cattle antemortem and analysed using copro ELISA test-kits and gross lesions were inspected at postmortem. Out of one hundred and eighty six (186) faecal samples analysed, over-all prevalence was 98(52.7%). From each abattoir was 38 (38.8%), 36 (36.7%) and 24 (24.5%) at Karu, Dei-Dei and Gwagwalada abattoirs respectively. Based on body condition scoring, infection rates were 39 (58.2%), 45 (58.4%) and 20 (47.6%) from cattle with poor, moderate and good body conditions accordingly. Males had a higher prevalence rate of 48 (50%) than females with 40 (44.4%). Based on the breed of cattle, infection rate of the diseases was 41 (66.1%), 39 (62.9%) and 20 (32.3%) in White fulani, Sokotogudali and Red bororo accordingly. Out of 186 cattle inspected at postmortem, 47 livers were condemned totally due to the presence of liver flukes (Fasciola species) in the hepatic parenchyma, fluke tracts, livers were friable and chirrotic. This led to an estimated loss of about three million, one hundred and two thousand naira (3,102,000.00). There was no statistically significant association between the infection and breed, sex and body condition score (p>0.05). Treatment of all cattle with an effective flukicides, vector control, enlightening of cattle farmers for proper intervention against fasciolosis are recommended.
