Impaired barrier functions of the intestines decrease the opsonization activity of the humoral immunity and bacteriostatic capacity Therefore, microorganisms in the intestines pass the mucosal barrier and reach the liver spleen, and mesenteric lymph nodes
in the gastrointestinal tract, thereby disrupting the functions of the immune and reticuloendothelial systems [3-6].
Finally, mesenteric lymph nodes
were harvested for cultures as well.
Seventeen out of 40 necropsied goats showed slightly or moderately enlarged mesenteric lymph nodes
, while no obvious lesions were observed in MLN of other goats.
Bacteria were also found in the mesenteric lymph nodes
, spleen, liver, and kidneys.

biopsy pathology findings Histological Findings No.
By ISH analysis, abundant cytoplasmic viral nucleic acid was detected in macrophages within germinal centers and subcapsular and medullary sinuses of the mesenteric lymph nodes
from all 4 dogs (Figure 2, panel H), mandibular lymph nodes from 2 dogs, ileal Peyer's patches from all 4 dogs (Figures 2, panels D, F), ellipsoids (terminal arterioles) of the spleen for 1 dog, and germinal centers in splenic white pulp for 2 dogs.
Gross examination of para-aortic and mesenteric lymph nodes
from patient 1 demonstrated 3 lymph nodes with tan-to-white cut surface and multiple pinpoint white spots throughout the nodes.
As per the study by Sivit CJ, Newman KD, Chandra RS mesenteric lymph nodes
were detected in 14% of symptomatic children, but enlarged mesenteric lymph nodes
in children with acute pain represents a non-specific finding.
In addition, there were scattered moderate-sized mesenteric lymph nodes
2), appendix was not inflamed, and few mesenteric lymph nodes
We found no TB-like visible lesions; pooled tissue samples (retropharyngeal, tracheobronchial, mediastinal, and mesenteric lymph nodes
) were submitted for bacterial culture and molecular diagnosis (6); urine, feces, and oropharyngeal swabs were taken, and DNA was extracted as previously described (7).
Mesenteric lymph nodes
that are smaller than 4.6 mm in short axis and are accepted as within normal limits of dimensions can be clearly identified on CT.
