Abstract The incidence of nontuberculous mycobacterial infections is increasing worldwide; by 2017, more than 190 species and subspecies have been documented. Although classically associated with immunosuppression, the recognition of these etiological agents in diseases affecting immunocompetent individuals and in healthcare-associated infections, such as after surgical and cosmetic procedures, makes the study of the epidemiology and pathogenesis of these microorganisms relevant in medical practice. Mycobacterium lentiflavum is slow-growing and rarely affects the skin. A case of cutaneous mycobacteriosis caused by M. lentiflavum is reported in an immunocompetent patient after subcutaneous injection of a lipolytic compound, treated with clarithromycin and levofloxacin.

É descrito um caso de co-infecção leishmania/HIV com manifestações cutâneas e visceral. Infecção pela leishmania foi confirmada através de métodos convencionais (parasitológicos e sorológicos) e através da PCR. A espécie Leishmania chagasi isolada da pele foi caracterizada por eletroforese enzimática e por polimorfismo de fragmento obtido por enzima de restrição.

A case of HIV/Leishmania co-infection presenting both visceral and cutaneous manifestations is reported. Leishmania infection was confirmed by conventional methods (parasitological approach and serology) and by PCR. Leishmania chagasi isolated from the skin lesion was characterized by enzyme electrophoresis and by restriction fragment length polymorphism of the internal transcribed spacer of the ribosomal gene.

RESUMO - Dois programas nutricionais foram testados em potros Mangalarga Marchador: TA - suplementação com concentrado suplementar dos 2 aos 12 meses de idade e TB - suplementação com concentrado suplementar da desmama aos 12 meses de idade. Os animais foram destinados a dois piquetes formados pelas gramíneas coast-cross (Cynodon dactylon x Cynodon nlemfluensis) + Estrela Africana (Cynodon nlemfluensis) e coast-cross (Cynodon dactylon x Cynodon nlemfluensis), respectivamente, e mensalmente foram pesados (P), mensurados (altura na cernelha - AC, perímetro torácico - PT) e avaliados quanto à ocorrência de deformidade flexural. Os 22 potros, filhos de três garanhões diferentes, nasceram entre setembro de 1993 e fevereiro de 1994 e foram designados para TA e TB, de acordo com o seguinte critério: cada dois potros de mesmo sexo, filhos do mesmo garanhão e nascidos cronologicamente o mais próximo possível, foram sorteados para cada tratamento, em delineamento inteiramente casualizado. As médias foram comparadas pelo teste Fisher. Os resultados demonstraram que os potros de TA tiveram melhor AC, PT, na época da desmama, e melhor PT, aos 12 meses de idade. Os animais de TB apresentaram ganho compensatório nas medidas de AC. Não foi observado, ao exame clínico, deformidade flexural nos potros de ambos os tratamentos.

ABSTRACT - Two nutrition programs were tested on Mangalarga Marchador foals: TA: supplementation with concentrate from 2 to 12 months of age and TB: supplementation from weaning to 12 months of age. Animals from TA and TB were kept in either one of the available feedlots: one of coast cross (Cynodon dactylon x Cynodon nenfluensis) + Cynodon nenfluensis grasses and the other of coast cross (C. dactylon x C. nenfluensis) only. Monthly the animals were weighed (W) and measured: height at withers (HW) and chest girth (CG) and flexure limbs deformities frequency. The 22 foals were born from September 1993 to February 1994 and they were allotted to each treatment, according to their sex, stallion and chronological birth, in a completely randomized design. Means were compared through the F test. The results showed that TA foals showed better HW and CG at weaning and better CG at 12 months. Foals under TB showed compensatory gains on HW from weaning to 12 months of age. There was not clinical evidence of limb flexure deformities in both programs.
