Granuloma stage was marginally positive correlated with TNF-, and negatively correlated with IL-10 gene expression when all time-points were combined; however, no correlation was seen at individual time points (Supplementary Tables 13). doi: 10.1016/j.vetimm.2006.07.001, 47. Pathogenesis of Mycobacterium bovis infection in cattle Would you like email updates of new search results?

Tissues were examined for gross lesions and processed for microscopic analysis as described previously (29). The burden range was high, as a number of granulomas from animals examined 30 days post-infection had bacterial burdens >105 CFU/g while a single granuloma from steer #439, 30 days post-infection contained no culturable M. bovis (i.e., sterile granuloma). Isolation of M. bovis from milk, knowledge gap on zoonotic TB and practice of consumption of raw milk in the study population showed potential risk for zoonotic transmission. Pearson correlation coefficients (r) for cytokine expression, bacterial burden (CFU/g) and granuloma stage in pulmonary granulomas examined at all time-points combined (30, 90, 180, and 270 days after infection) from calves experimentally infected with aerosolized M. bovis.

All individual granulomas were staged according to criteria described previously (24, 25, 37, 38). Our group evaluated a more rapid and specific method, based on a new polymerase chain reaction species-specific primers, which amplifies a 470-base pair fragment of the M. bovis genome. doi: 10.1016/j.vaccine.2008.12.018, 44. Necrosis is a consistent feature of many tuberculoid granulomas, regardless of mycobacterial species, host species or target organ, intimating the importance of this process in the pathogenesis of tuberculosis. In cases where numerous granulomas were present, a maximum of 5 granulomas each from five lung lobes were collected for a total of 25 granulomas per steer.

When all timepoints were combined, there a was marginally positive correlation between bacterial burden and IL-10 expression; otherwise at any individual time point there was no correlation between bacterial burden and gene expression for any cytokine (Table 1). In May 2023, Frontiers adopted a new reporting platform to be Counter 5 compliant, in line with industry standards. Keywords: Links to PubMed are also available for Selected References.

Lung lobes (left cranial, left caudal, right cranial, right caudal, middle and accessory) were assessed individually based on the following scoring system: 0, no visible lesions; 1, no external gross lesions, but lesions seen on slicing; 2, <5 gross lesions of <10 mm in diameter; 3, >5 gross lesions of <10 mm in diameter; 4, >1 distinct gross lesion of >10 mm in diameter; 5, gross coalescing lesions.

Between each incubation step, slides were washed with fresh 1X Wash Buffer (Advanced Cell Diagnostics). Correlations between multiple variables were analyzed using Pearson correlation coefficients (GraphPad Prism 8.0). Variability in tuberculosis granuloma T cell responses exists, but a balance of pro- and anti-inflammatory cytokines is associated with sterilization.

Transbound Emerg Dis. Infect Immun. (2007) 44:86374. The NHP model has also demonstrated a higher bacterial burden in lesions arising at earlier time points and a significant reduction in bacterial burden after the onset of adaptive immunity, consistent with the findings in this study (12).
