Lechiguana is a disease of cattle characterized by large, hard, subcutaneous swellings that grow rapidly and result in death after 3–11 months in untreated animals. Cattle treated with antibiotics recover. The disease has been reported from five states in south and southeastern Brazil. Histologically, the lesion consists of focal proliferation of fibrous tissue infiltrated by plasma cells, eosinophils, lymphocytes and sometimes neutrophils. The primary lesion is an eosinophilic lymphangitis… Expand
Pathological aspects of bovine focal fibrogranulomatous proliferative panniculitis (Lechiguana)
TLDR
Angiogenesis was the most characteristic finding in both proliferative and regressive stages as seen by the immunohistochemical expression of cytoskeleton proteins and von Willebrand (Factor VIII-Related Antigen). Expand
Isolamento de Arcanobacterium pyogenes de granuloma actinomicóide em bovino
TLDR
It is concluded that A. pyogenes could be involved in actinomycotic-like lesion with clinical and pathological aspects similar to lechiguana, tuberculosis and actinobacilosis. Expand

TLDR
The histopathology of purulent bronchopneumonia associated with M. granulomatis in a Belgian hare resident in British Columbia, Canada is described and the lesions compared with those caused by M. haemolytica in livestock are compared. Expand

IDENTIFICATION OF A NOVEL MANNHEIMIA GRANULOMATIS LINEAGE FROM LESIONS IN ROE DEER (CAPREOLUS CAPREOLUS)
TLDR
Eight atypical Mannheimia isolates were isolated from lesions in roe deer and extensive phenotypic characterization suggested that the isolates should be classified as M. granulomatis, although the presence of distinct traits justified their classification into a separate biogroup within this species.

Molecular study on Pasteurella multocida and Mannheimia granulomatis from Kenyan Camels (Camelus dromedarius)
TLDR
This study is the first to apply state of the art molecular methods to shed light on the nasopharyngeal carrier state of Pasteurellaceae in camels, demonstrating a hitherto unrecognised active carrier state for M. granulomatis or a closely related new Mannheimia species from camelids. Expand
The forgotten role of lymphangitis in Crohn’s disease
TLDR
Attention should be directed at defining the initial damage to lymphatic endothelium and agents that might be responsible of the basic changes in Crohn’s disease. Expand
Microanatomy of the intestinal lymphatic system
TLDR
Vital to progress in understanding how the intestinal lymphatic system functions is the integration of recent advances identifying molecular pathways for lymphatic growth and remodeling with advanced imaging modalities to observe lymphatic function and dysfunction in vivo. Expand

Lymphatic Vessel Network Structure and Physiology.
TLDR
A comprehensive review of important findings over the past century along with recent advances in the understanding of the anatomy and physiology of lymphatic vessels, including tissue/organ specificity, development, mechanisms of lymph formation and transport, lymphangiogenesis, and the roles of lymphatics in disease are provided.

Bovine Focal Proliferative Fibrogranulomatous Panniculitis (Lechiguana) Associated with Pasteurella granulomatis
TLDR
In southern Brazil, cattle affected by a disease known locally as Lechiguana and characterized by large subcutaneous swellings, it is postulate that this insect may transmit the causative agent. Expand
Toxin Production by Pasteurella granulomatis
TLDR
It is concluded that some Pg isolates have variable hemolytic and/ or leukotoxic properties and that this variability (presence and/or degree) of these 2 properties may affect the relative pathogenicity of Pg in susceptible cattle. Expand
Role of Pasteurella granulomatis and Dermatobia hominis in the Etiology of Lechiguana in Cattle a
TLDR
The apparent long incubation period, the negative results obtained in the other experiments, and also the infrequent occurrence of the natural disease suggest that lechiguana is a disease for which Koch's postulates are not easily fulfilled. Expand
The Use of Polymerase Chain Reaction to Identify Pasteurella granulomatis from Cattle
TLDR
The present study was initiated to use polymerase chain reaction (PCR) amplification in order to recognize Pg DNA from cultures and possibly from bacteria within bovine or insect tissue, and to show the relatedness of Pg strains to each other and to other Pasteurella and Actinobacillus spp. Expand

TLDR
Three strains of a Pasteurella haemolytica-like bacterium were isolated from lesions of a progressive granuloma of cattle in southern Brazil, and a name is proposed for this apparently new taxon. Expand

TLDR
Based on the polyphasic investigation performed a new genus Mannheimia is proposed for the trehalose-negative [P.] haemolytica complex, and two previously named species are transferred to this new genus and three new species are described. Expand
