RESUMO.-[Treponema denticola na microbiota da periodontite bovina.] A periodontite bovina é um processo infeccioso purulento e progressivo associado à presença de biofilme subgengival anaeróbio estrito e epidemiologicamente relacionada ao manejo do solo em amplas áreas geográficas do Brasil. O trabalho teve por objetivo detectar espécies de Treponema presentes na bolsa periodontal de bovinos com lesões de profundidade maior que 5mm e do sulco gengival de animais com idade de 6 a 24 meses e considerados periodontalmente sadios. Os materiais foram colhidos por meio de cones de papel, após a remoção do biofilme supragengival, e mantidos sob congelamento (-80°C) até a extração do DNA e realização da reação em cadeia da polimerase (PCR) com o emprego de iniciadores de T. amylovorum, T. denticola, T. maltophilum, T. medium e T. vincentii. Na bolsa periodontal de 73% (19/26) dos animais foi possível detectar diretamente, pela PCR, a presença de Treponema amylovorum, de 42,3% (11/26) T. denticola e de 54% (14/26) T. maltophilum. Dos 25 sítios sadios, em 18 (72%) foi possível identificar T. amylovorum, em dois (8%) T. denticola e em oito (32%) T. maltophilum. Treponema medium e T. vincentii não foram detectados nas 51 amostras avaliadas. A presença de Treponema amylovorum, T. maltophilum na microbiota subgengival, e em especial do amplamente reconhecido periodontopatógeno T. denticola, Treponema denticola in microflora of bovine periodontitis Periodontitis in cattle is an infectious purulent progressive disease associated with strict anaerobic subgingival biofilm and is epidemiologically related to soil management at several locations of Brazil. This study aimed to detect Treponema species in periodontal pockets of cattle with lesions deeper than 5mm in the gingival sulcus of 6 to 24-month-old animals considered periodontally healthy. We used paper cones to collect the materials, after removal of supragingival plaques, and kept frozen (at -80°C) up to DNA extraction and polymerase chain reaction (PCR) using T. amylovorum, T. denticola, T. maltophilum, T. medium and T. vincentii primers. In periodontal pocket, it was possible to identify by PCR directly, the presence of Treponema amylovorum in 73% of animals (19/26), T. denticola in 42.3% (11/26) and T. maltophilum in 54% (14/26). Among the 25 healthy sites, it was possible to identify T. amylovorum in 18 (72%), T. denticola in two (8%) and T. maltophilum in eight (32%). Treponema medium and T. vincentii were not detected over all 51 evaluated samples. The presence of Treponema amylovorum, T. maltophilum and, in particular, the widely recognized T. denticola in subgingival microflora brings an original and potencially important contribution in studies of the bovine periodontitis.INDEX TERMS: Bovine periodontitis, periodontal disease, subgingival microflora, Treponema denticola.

“…In humans, it is now understood that the immune and inflammatory responses are critical to the pathogenesis of periodontitis and are shaped by several hostrelated factors, both intrinsic (e.g., genetics) and induced (e.g., pollutants). For Döbereiner et al (2004), Moraes et al (1994) and Rosa and Döbereiner (1994), there is no evidence of a relationship between the periodontitis of cattle and mineral imbalance or deficiency; these authors demonstrated that the bone changes are of secondary origin and are not caused by a deficiency of P or other minerals. Therefore, by analogy based on the findings of the present study, the issue of mineral imbalance or deficiency should not be considered as a triggering factor for periodontal disease in sheep.…”

“…In the past, it has been hypothesized that the periodontal disease of cattle was a metabolic disease from a mineral imbalance, with the involvement of calcium (Ca) and phosphorus (P), as well as other minerals, with special emphasis on copper (Cu) (Camargo et al, 1981;Nazário, 1984;Soni, 1984). However, in later studies, Moraes et al (1994) and Döbereiner et al (2004) concluded that the swollen face in cattle was not a consequence of mineral deficiency or imbalance.…”

“…In Brazil, periodontitis in cattle (commonly known as "swollen face") affects young animals (i.e. mainly calves) when teeth erupt (Döbereiner et al, 1974(Döbereiner et al, , 2000(Döbereiner et al, , 2004. This disease was first described in sheep in Brazil in 2016 (Silva et al, 2016) and the affected animals presented enlargement of the upper jaw, alveolar bone loss, and in final stages, loosening and loss of lower and upper molars; in the most severe cases, abscess formation and fistula were present, with drainage of purulent exudate.…”

Due to the supposed involvement of minerals in cases of ruminant periodontitis, this study aimed to analyze the concentrations of phosphorus (P) in bone, and cobalt (Co), copper (Co), iron (Fe), zinc (Zn) and selenium (Se) in liver of a cohort of sheep affected or not by periodontitis. From an outbreak of the disease in 2011 in Pará state, Brazil, rib and liver samples were obtained from 22 sheep with periodontitis and seven samples from healthy animals. Based on the concentrations of the different minerals in the tissues, we concluded that there was no relationship between periodontal disease in sheep with any mineral deficiency status. In contrast, most of the minerals in the tissues were above or within the recommended concentrations in bone and liver. Within the various aspects which until now have been studied regarding periodontitis in ruminants, the results obtained here corroborate the fact that periodontal disease in sheep is an infectious disease and it is not a consequence of the deficiency or excess of mineral elements in the diet.

“…The bovine epizootic periodontitis, a purulent periodontitis capable of causing chronic ossifying periostitis, was also discarded, since the animal had already passed the phases of tooth eruption and there were no oral lesions on the marginal gingiva or periodontal pockets (Döbereiner et al, 2004).…”

A 9-year-old Girolando dairy cow, weighing 400kg, with a history of increased volume in the right parotid region, which extended to the submandibular region, was assisted. Fine needle aspiration cytology was performed, and the cytological findings were consistent with malignant neoplasm of epithelial origin (carcinoma). Because of the unfavorable prognosis, the animal was euthanized and submitted to an anatomopathological examination. Samples of the increased parotid and affected lymph nodes were collected for histopathological evaluation. The microscopic changes were accentuated features of anaplasia, moderate cell proliferation, atypical mitotic figures, and necrosis. Stroma ranged from delicate to scirrhous, and the tumor boundaries were not distinct. These findings substantiated the preliminary histomorphological diagnosis of undifferentiated carcinoma with metastasis in lymph nodes. Immunohistochemical tests were performed with anti-CK Pan (clone AE1AE3), anti-CK HMW (clone 34βE12), anti-CK19 (clone RCK108), anti-vimentin (clone V9), anti-S100 (polyclonal), and antiandrogen (polyclonal) antibodies. The immunophenotype favored the diagnosis of salivary gland adenocarcinoma. Despite the rareness in cattle, salivary gland adenocarcinoma should be considered in the differential diagnosis of diseases that occur with increased volume in the head, lymphadenopathy, drooling, dysphagia, and progressive weight loss.
