Field Evaluation of the Interferon Gamma Assay for Diagnosis of Tuberculosis in Water Buffalo ( Bubalus bubalis) Comparing Four Interpretative Criteria. Front Vet Sci 2020; 7:563792.

Abstract
Bovine tuberculosis (bTB) is a worldwide zoonosis that affects many species of domestic and wild animals. Mycobaterium bovis is the main cause of infection in water buffalo (Bubalus bubalis) and bovines and is of great concern for human health and for buffalo producers in Italy. The bTB eradication programme is based on slaughterhouse surveillance and intradermal skin tests. Other in vivo diagnostic methods such as the interferon-gamma (IFN-γ) assay have been developed and are widely used in cattle to accelerate the elimination of bTB positive animals. The present study is the first to assess the use and performance of IFN-γ assays, which is used as an ancillary test for bTB diagnosis in water buffalo, and presents the results of a field-evaluation of the assay from 2012 to 2019 during the buffalo bTB eradication programme in Italy. The study involved 489 buffaloes with a positive result to the single intradermal tuberculin test (SITT). The IFN-γ assays and single intradermal comparative tuberculin test were used as confirmation tests. Then, a total of 458 buffaloes, reared on officially tuberculosis-free (OTF) herds, that were confirmed bTB-free for at least the last 6 years were subjected to IFN-γ testing. Furthermore, to evaluate the IFN-γ test in an OTF herd with Paratuberculosis (PTB) infection, 103 buffaloes were subjected to SITT and IFN-γ test simultaneously. Four interpretative criteria were used, and the IFN-γ test showed high levels of accuracy, with sensitivity levels between 75.3% (CI 95% 71.2–79.0%) and 98.4% (CI 95% 96.7–99.4%) and specificity levels between 94.3% (CI 95% 91.2–96.50%) and 98.5% (CI 95% 96.9–99.4%), depending on the criterion used. Finally, in the OTF herd with PTB infection, in buffalo, the IFN-γ test displayed high specificity values according to all 4 interpretative criteria, with specificity levels between 96.7% (CI 95% 88.4–99.5%) and 100% (CI 95% 96.2–100%), while SITT specificity proved unsatisfactory, with a level of 45.3% (CI 95% 35.0–55.7%). Our results showed that the IFN-γ test in the buffalo species could reach high Sensitivity and Specificity values, and that the level of Sensitivity and Specificity could be chosen based on the interpretative criterion and the antigens used depending on the health status of the herd and the epidemiological context of the territory. The IFN-γ test and the use of different interpretative criteria proved to be useful to implement bTB diagnostic strategies in buffalo herds, with the possibility of a flexible use of the assay.

High prevalence of subclinical paratuberculosis in buffaloes (Bubalus bubalis) in Maranhão, Brazil. Braz J Microbiol 2020; 51:1383-1390. [PMID: 32291741 DOI: 10.1007/s42770-020-00267-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2019] [Accepted: 03/24/2020] [Indexed: 11/29/2022] Open
Abstract
Paratuberculosis is an infectious, chronic, and incurable disease that affects ruminants, causing enteritis and chronic granulomatous lymphadenitis, characterized by malabsorption syndrome, its agent is the Mycobacterium avium subsp. paratuberculosis (MAP). Thus, the objective of this work was to identify and characterize MAP in buffalo herds slaughtered in Baixada Maranhense region. Samples of intestines, mesenteric lymph nodes, and ileocecal valves were collected from 115 buffaloes slaughtered at Baixada Maranhense slaughterhouses to perform the diagnosis by histopathological examination using staining with Hematoxylin and Eosin (H&E) and Ziehl-Neelsen, bacterial isolation, and real-time PCR. In the histopathology by H&E staining, there was evidence suggestive of paratuberculosis in 30% (31/115) of the buffaloes. With Ziehl-Neelsen staining, acid-fast bacilli (AFB) were visualized in 27% (26/115) of the tissue samples analyzed. MAP was isolated in 4.3% (5/115) of the fecal samples subjected to bacterial culture. The samples inoculated in HEYM with mycobactin J produced colonies identified with MAP according to their own morphological characteristics such as round, white, smooth and slightly rough, alcohol-acid staining, and slow growth with 8 weeks of incubation and mycobactin dependence. The agent confirmation was performed in five bacterial isolates (4.3%) and 15 (13%) fragments of jejunum, ileum, and mesenteric lymph node by the IS900 real-time PCR technique. The results of the present study demonstrate the subclinical occurrence of paratuberculosis in flocks of buffalo slaughtered in slaughterhouses of Baixada Maranhense.

Abstract
Paratuberculosis is an incurable disease in ruminants with great worldwide economic impact, caused by Mycobacterium avium subsp. paratuberculosis (MAP). The objective of this study was to carry out a study of the molecular epidemiology of the MAP using the restriction enzyme analysis (REA) technique of IS1311 MAP region in biological samples of feces, intestinal tissue, and mesenteric lymph nodes of cattle and buffaloes from six Brazilian states. In total, 109 samples of feces and tissues of cattle and buffaloes were collected from animal paratuberculosis suspected. Twenty-five samples were positive in the detection of the DNA of the IS900 region of MAP and it was possible to type 18 strains in the analysis of the region IS1311, being 100% of them identified as belonging to subtype Bison MAP strain. This is the first epidemiological molecular study of MAP in Brazil. The results indicate that paratuberculosis is widespread in cattle and in buffaloes in several regions of Brazil, and the subtype Bison MAP strain was the only one identified in the samples analyzed in this study, demonstrating the similarity between the strains from different states tested. These results provide the necessary support for the implementation of paratuberculosis control strategies in cattle and buffaloes in Brazil.

Abstract
Latin America is the definition of the American group, where languages of Latin origin are spoken, including countries in South, Central, and North America. Paratuberculosis is a gastrointestinal contagious chronic disease that affects ruminants, whose etiological agent is the bacilli Mycobacterium avium subsp. paratuberculosis (MAP). Paratuberculosis is characterized by intermittent diarrhea, decreased milk production, dehydration, and progressive weight loss and is possibly involved in Crohn's disease, a human intestinal disease. MAP is resistant to environmental factors, pasteurization, and water disinfection, which coupled with the subclinical-clinical nature of the disease, and makes paratuberculosis a relevant socioeconomic and public health issue, justifying the descriptive review of research on the disease carried out in Latin American countries. A survey of articles, published until September 2016, on the Scopus database, PubMed, Agris, and Science Direct, about detection of the agent and the disease in Latin America, without restrictions to the date of the research was performed. The keywords were as follows: "paratuberculosis," "Mycobacterium avium subsp. paratuberculosis," "cattle," "milk," "wildlife," "goat," "ovine," "dairy," and the name of each country in English. Studies found from nine of the 20 Latin America countries, 31 related to Brazil, 17 to Argentina, 14 to Chile, eight to Colombia, six to Mexico, two to Peru, two to Venezuela, and one to Panama and to Bolivia, each. The agent was detected in cattle, goats, sheep, domesticated water buffalo, and wild animals. Microbiological culture, PCR, and ELISA were the frequent techniques. The small number of studies may result in overestimation or underestimation of the real scenario.
