Low frequency of LRV1 in Leishmania braziliensis strains isolated from typical and atypical lesions in the State of Minas Gerais, Brazil

AbstractThe bush dog Speothos venaticus, a rare Near Threatened South American canid that lives in packs, was thought to be extinct in Minas Gerais state, south-eastern Brazil, until recently. Here, we report four recent records of the species in Minas Gerais, the first in the state since the description of the species in 1842. All records are from the Cerrado ecosystem in the north and north-west of the state; two are from animals found dead, one from footprints and another from a camera trap. Three of the records were inside or close (< 10 km) to strict protected areas, in a region recognized as the Protected Areas Mosaic Sertão Veredas–Peruaçu, where we expect any new records of the bush dog to be found. We discuss the low probability of detecting the bush dog and the main regional threats to the species, and emphasize the need to protect large and interconnected natural areas and keep them free of domestic dogs to avoid the extinction of the bush dog in Minas Gerais.

As a result of the study, it was found that the removal of dental plaque using low-frequency ultrasound and ozonized contact medium in chronic generalized catarrhal gingivitis of young people can significantly improve the state of microbiocenosis of the gingival sulcus. The preservation of the main resident species is noted, occasional transient species disappear and the frequency of isolation of aggressive representatives of beta-hemolytic streptococci and periodontopathogenic species decreases. When using ozonated water for the removal of dental deposits, the efficiency of eradication of the microbiota of the gingival sulcus, especially of representatives of aggressive species, is higher than when removing dental deposits without the use of ozonated water.

Complete Study

Abstract Among the diseases which can afflict the nasal cavities of small ruminants, oestrosis stands out. In Brazil, more specifically in its South-East region, the reports are limited only to the State of São Paulo and to the municipality of Araxá, Minas Gerais. Therefore, it has been sought to assess the parasitic prevalence of Oestrus ovis in sheep farmed in the municipality of Ituiutaba, Minas Gerais-Brazil, while correlating the larval size and stage, and its anatomical localization. Eighty-eight hemiheads of healthy Santa Inês/Dorper crossbreds Ovis aries have been used at random. The larvae in view were then collected and fixated to be quantified and analyzed in regard of size and stage of development. It is concluded that the oestrosis is an existing problem in the municipality of Ituiutaba, this being the first complete study on the prevalence of this parasite in the State of Minas Gerais. By anatomical distribution, only the differences of total larval averages between the frontal sinus and the ventral nasal meatus, the common nasal meatus and the nasopharynx have been significant. In size, the significant difference has been there only upon comparison between the size and the larval stage, information that is crucial for a better understanding of the cyclic progression, of the clinical symptomatology, and animal prophylaxis.

A new species, Calea arachnoidea, which belongs to Calea sect. Meyeria, is hereby described and illustrated. This species occurs in the Serra Negra region, located in the southern portion of the “Zona da Mata” in the state of Minas Gerais, southeastern Brazil. Calea arachnoidea resembles C. quadrifolia, C. heteropappa and C. semirii, and its relationships with these species are discussed and an identification key for the species of C. sect. Meyeria in the state of Minas Gerais is provided. Additionally, photographs, a distribution map, comments about habitat and conservation status are provided.

OBJECTIVE: The objective of this study was to determine the incidence and etiology of congenital hypothyroidism (CH) in Uberaba, MG. SUBJECTS AND METHODS: From 2001 to 2010, by reviewing patient files from a public reference outpatient unit. The screening program covered 88% of live-born children. RESULTS: CH was diagnosed in 16 children, representing an incidence of 1:2,017 live-born children screened. The etiological evaluation was done in 15 children and revealed seven cases of thyroid dysgenesis, seven of dyshormonogenesis, and one case of transient hypothyroidism. One child moved away from the state before etiological investigation was carried out. CONCLUSION: We concluded that both the incidence of CH and of dyshormonogenesis as the main causes of CH were increased in the investigated region, but molecular studies are necessary for a better definition of etiology.
