To determine the incidence of brucella abortus and certain other organisms in tonsils
… from tonsil tissue. It is obvious that normal tonsils would not be available for this study and, therefore, one was compelled to use organs which had been removed for one reason or another - "enlarged tonsils ". From the stand point of the investigation, however, these might be regarded as …

Tuberculosis in childhood : the sources and channels of infection : with special reference to the tonsils
In conclusion, to summarise my results, I found that out of a total of 307 cases, 213 were of respiratory origin, through the lungs or the middle ear; 53 were due to the ingestion of tuber -l' culous material; 6 were due either to respiration or to ingestion, having been infected through the mouth …

The foramen magnum and its contents : a magnetic resonance imaging study of the normal spatial relationships
… with caudal displacement of the cerebellar tonsils through the fora men magnum (Chiari malformation) have lead to many radiological studies of the region. With MRI, routine sagittal and parasagittal views of the craniovertebral junction have shown that the position of the cerebellar tonsils …

Determination of functionally distinct subsets of human tonsillar and blood T follicular helper (Tfh) cells.
… to determine the biology of Tfh cells in human tonsils. We hypothesized that human Tfh cells are composed of functionally distinct subsets. We also determined the type of Tfh responses induced by influenza vaccination in healthy adults. First, we identified a Tfh subset localized outside …

New Mediators and Novel Mechanisms in Allergic Airway Inflammation
… on material derived from the nose, the palatine tonsils and cultured epithelial cells. In the nose, immunohistochemical staining for S100A7 was seen in the epithelium and in seromucous glands. DNA microarray analysis demonstrated increased levels of S100A7 in nasal lavage fluid cells obtained …

Charakterisierung des Zytokins BAFF als wichtiger Regulator der B-Zellfunktion beim Haushuhn
… also observed in lymphocyte cultures from ceacal tonsils and in cultures of purified (>95%) splenic B-cell preparations. While the rapid apoptosis in cultures of bursal lymphocytes could not be completely prevented, chBAFF clearly increased the survival of these immature B-cells. CFSE labelling …

Correlation Matrix Analysis Identifies Gene Signatures of Immune Cell Subsets and Their Interactions In Follicular Lymphoma
… Comparison of gene signatures between FL and tonsils (n=24) suggested that TFH cells and macrophages are qualitatively distinct in FL from normal tissue. “Cross-correlation”, between FL NB fraction signatures and individual B fraction genes, suggests that TFH cells promote proliferation, …

Novel molecular markers of disease-association among strains of Streptococcus suis: a genomic approach
… or ii) asymptomatic carriage on the palatine tonsils of swine. Chapter 4 then describes the analyses used to select three genetic markers to pathotype S. suis - differentiate isolates of the same species based on their ability to cause disease; going on to describe the design and evaluation of …

Clinical correlations to distinguish from milder forms of obstructive sleep apnoea syndrome using overnight oximetry to prioritize adenotonsillectomy in a low resource setting
… an additional clinical finding of grade 3 or 4 tonsils. These children should have surgery expedited. Any child with a MOS 3 or 4 score on OO needs to have expedited surgery.

Mechanism of Pathogenesis and Replication of an Avian Strain of the Hepatitis E Virus in a Chicken Model
… colon, cecum, jejunum, ileum, duodenum and cecal tonsils,but not in other non-GIT tissues. Immunohistochemistry using an avian HEV capsid protein-specific anti-peptide antibody revealed positive signal in liver and GIT tissues including colon, jejunum, ileum, cecum, cecal tonsils and pancreas. The …

One Health investigation at abattoirs in South Africa
… tissue (kidney, liver, spleen, lymph nodes and tonsils) samples were collected from corresponding animals. The objective of the study included determining the seropositivity and co-infection of infectious/zoonotic pathogens in slaughtered animals. This was achieved by serum screening using Rose …

Early Events Following Oral Transmission of Simian Immunodeficiency Virus: From Viral Entry to Host Immune Response
… the oral and esophageal mucosa, as well as the tonsils. Furthermore, SIV rapidly disseminated to peripheral lymph nodes resulting in systemic infection by 2 to 4 days post-infection. The rapidity with which SIV spreads throughout the lymphatics indicates a major obstacle for a vaccine recall …

KSHV Susceptibility and Transmission Within Tonsillar Specimens
… cell-to-cell transmission of KSHV within human tonsils by examining KSHV spread within and between primary cell types derived from tonsil specimens, located at the proximity of the crypt lumen, which are in direct contact with external pathogens present in saliva. We show that a variety of …

Microbiome Dynamics in Broilers Infected with Infectious Bronchitis Virus and the Protective Role of Lactobacillus-Based Probiotics
… with IBV DMV/1639 strain. Trachea and cecal tonsils of IBV challenged group showed significantly higher histopathological lesions score compared to control. Significantly higher alpha diversity indexes including observed Operational Taxonomic Units (OTUs) and Shannon was observed in IBV …

In ovo supplementation of Primalac and the effects on performance and immune response of broilers
… of immune-related genes in the ileum and cecal tonsils. On embryonic day 18, 360 eggs were injected with water, 1x105, 1x106, or 1x107 probiotic bacteria. Another 90 eggs remained uninjected as a negative control group. Measurements and tissue samples were taken on day of hatch (DOH) and days …

Molecular characterization of the major envelope protein of porcine reproductive and respiratory syndrome virus (PRRSV) and evaluation of its use for a diagnostic assay, vaccine development, and the examination of quasispecies evolution
… cDNA clone directly into the lymph nodes and tonsils of pigs produces active PRRSV infection. Using this method, we also examined the quasispecies populations of PRRSV. Finally, we evaluated the ability of Salmonella choleraesuis to express the PRRSV GP5, and tested its immunogenicity in mice. …

In ovo and feed application of probiotics or synbiotics and response of broiler chicks to post-hatch necrotic enteritis
… of D14 TLR2, D14 TNF-α, and D42 LEAP2 in cecal tonsils compared to controls. PI+ increased mRNA abundance of D7 and D42 MUC2, D7 LEAP2, and D42 TNF-α in the ileum. PI+ increased mRNA abundance in the cecal tonsils of D7 TLR2 and D42 TNF-α. These studies yielded interesting results about …

Gnotobiotic Pig Models for the Study of Enteric Pathogen Replication and Pathogenesis
… infection primed immune responses in the ileum, tonsils, and facial lymph nodes; infection also induced high levels of systemic and mucosal rotavirus specific antibody responses. Moving forward, we hope to expand upon this replication study to identify what cell types within the glands are …
