ABSTRACT.
Protothecosis is a rare disease caused by environmental algae of the genus Prototheca. These are saprophytic, non-photosynthetic, aerobic, colorless algae that belong to the Chlorellaceae family. Seven different species have been described. Prototheca zopfii genotype 2 and P. wickerhamii are most commonly involved in pathogenic infections in humans and animals. The objective of this work is to describe, for the first time, a case of protothecosis caused by P. zopfii genotype 1 in a dog. The dog, a 4-year-old mix bred male, was presented to a veterinary clinic in Montevideo, Uruguay, with multiple skin nodules, one of which was excised by surgical biopsy. The sample was examined histologically and processed by PCR, DNA sequencing, and restriction fragments length polymorphisms for the detection and genotyping of P. zopfii. In addition, transmission electron microscopy and scanning electron microscopy were performed. Histology showed severe ulcerative granulomatous dermatitis and panniculitis with myriads of pleomorphic algae. Algal cells were 4?17 µm in size, with an amphophilic, 2?4-µm-thick wall frequently surrounded by a clear halo, contained flocculant material and a deeply basophilic nucleus, and internal septae with daughter cells (endospores) consistent with endosporulation. Ultrastructurally, algal cells/endospores at different stages of development were found within parasitophorous vacuoles in macrophages. Prototheca zopfii genotype 1 was identified by molecular testing, confirming the etiologic diagnosis of protothecosis. © Springer MenosABSTRACT.

ABSTRACT: The present study aimed to obtain, through statistical methods, the independent variables that influence the economic and
productive results of Brazilian beef cattle. Economic and productive information was collected from 106 farms in Brazil. Data collection was
performed by the Instituto de Métricas Agropecuárias (Inttegra). The variable selection method used was stepwise regression followed by
polynomial regression analyses. The variable beef cattle economic result showed the positive effect of disbursement per head per month and
average weight gain. An average daily gain of 520 g in live weight was obtained, and this variable was influenced especially by nutrition cost.
The arroba production (arroba is a unit of weight corresponding to 15kg) was influenced by the linear effect of nutrition cost and stocking rate.
The variable arroba production in pasture showed a linear and positive effect of average weight gain in pasture and stocking rate in pasture.
For profit per arroba, the variables nutrition cost, disbursement with pasture, and average sale price had a linear effect. The independent
variables that had the greatest influence on the response variables were stocking rate, average daily weight gain, and nutrition cost. Thus,
increases in investment in nutrition and stocking rate should result in higher production rates and improvements in the profitability of this
activity.
RESUMO: O presente trabalho teve como objetivo obter, por meio de métodos estatísticos, quais variáveis independentes influenciam as
variáveis econômicas e produtivas na bovinocultura de corte brasileira. O banco de dados utilizado foi obtido por coleta de informações
econômicas e produtivas em 106 fazendas no Brasil. O método de coleta de dados foi definido pelo Instituto de Métricas Agropecuárias
(Inttegra). Foram realizadas análises de seleção de variáveis pelo método Stepwise, seguido por análises de regressão múltipla. A variável
resultado econômico da bovinocultura de corte teve efeito positivo do desembolso mensal por cabeça e do ganho de peso médio diário.
Para o ganho de peso médio diário foi obtido um valor médio de 520 gramas, e esta variável foi influenciada principalmente pelo custeio
com nutrição. Para a produção de arroba foi obtido efeito linear do custeio com nutrição e da taxa de lotação. Para a variável produção de
arroba a pasto foi obtido um efeito linear e positivo do ganho médio diário de peso no pasto e da taxa de lotação no pasto. Para o lucro por
arroba, as variáveis custeio com nutrição, desembolso com pastagem e preço médio de venda tiveram efeito linear. As variáveis independentes
que tiveram maior influência nas variáveis resposta foram a taxa de lotação, o ganho médio diário de peso e o custeio com nutrição. Assim,
aumentos no investimento em nutrição e na taxa de lotação dos animais devem resultar em maiores índices de produção e em melhorias na
rentabilidade da atividade. MenosABSTRACT: The present study aimed to obtain, through statistical methods, the independent variables that influence the economic and
