O perfil físico-químico do leite humano ordenhado cru (LHOc) com acidez titulável acima de 7ºD após 15 dias de congelamento, teores de creme, gordura total e valor energético, foram avaliados. Na etapa controle, os valores absolutos de creme, gordura total e valor energético (n=3887) foram determinados pelo método do crematócrito e a acidez titulável (n=4204) do LHOc por um método titulimétrico adaptado de leite de vaca. Na etapa teste, determinou-se o teor de creme, gordura total e valor energético de amostras (n=66) com acidez acima de 7ºD armazenadas entre -10º e -18ºC por 15 dias. A acidez titulável variou de 0,5 a 21ºD (3,52 ± 2,45ºD) e os teores de creme, gordura total e valor energético foram, respectivamente, 4,90 ± 0,25 %, 4,49 ± 0,26 % e 617,47 ± 17,37 Kcal/Litro. Houve redução significante nos teores de creme (6,45 ± 2,28% para 5,79 ± 2,57%), gordura total (4,0 ± 1,81% para 3,49 ± 1,76%) e valor energético (716,27 ± 176,59 Kcal/Litro para 666,82 ± 171,90 Kcal/Litro), com p<0,05. O uso do teste da acidez titulável constitui uma ferramenta importante no controle de qualidade do LHOc.

The physiochemical profile of the human milk milked raw (HMMr) with titratable acidity above 7ºD after 15 days of freezing, the tenors of cream, total fat and energy value was determinated. In the control step, the absolute values of cream, total fat and energy value (N=3887) were determinated for the method of the creamatocrit, and the titratable acidity (N=4204) of the HMMr were determined for a method adapted of cow milk. In the test step, there was determined the tenor of cream, total fat and energy value of samples (n=66) with acidity above 7ºD stored between -10ºC and -18ºC by 15 days. The titratable acidity varied from 0.5 to 21ºD (3.52 ± 2.45ºD), and the tenors of cream, total fat and energy value were, respectively, 4.90 ± 0.25%, 4.49 ± 0.26% and 617.47 ± 17.37 Kcal / Liter. There was significant reduction in the tenors of cream (6.45 ± 2.28% for 5.79 ± 2.57%), total fat (4.0 ± 1.81% for 3.49 ± 1.76%) and energy value (716.27 ± 176.59Kcal / Liter for 666.82 ± 171.90Kcal/Liter) with p < 0.05. The use of the test of the titratable acidity constitutes one important tool in the quality control of the HMMr.

A candidíase, principal infecção fúngica oportunista do ser humano, é provocada por leveduras do gênero Candida que fazem parte da microbiota endógena do corpo humano. O objetivo deste trabalho foi estudar as espécies de Candida envolvidas em processos inflamatórios da mama em mães que estavam amamentando no Banco de Leite Humano da Maternidade-Escola Assis Chateaubriand da Universidade Federal do Ceará (UFC), verificando as atividades enzimáticas e as suscetibilidades aos principais antifúngicos usados na candidíase. As amostras foram colhidas de fissuras no mamilo, cultivadas em ágar Sabouraud a 37°C por 72 horas e identificadas por testes micológicos. Foram realizadas também provas da proteinase, fosfolipase e hialuronidase e testes de susceptibilidade a anfotericina B e fluconazol. Das 29 amostras, 13 (44,8%) apresentaram crescimento; 11 (84,6%) foram Candida albicans; uma (7,7%), C. stellatoidea;e uma (7,7%), C. guilliermondii. As atividades enzimáticas de C. albicans foram: 100% das cepas produziram fosfolipase; 64%, hialuronidase; e nenhuma produziu proteinase. As leveduras examinadas mostraram-se susceptíveis aos antifúngicos testados com concentração inibitória mínima (CIM) de: anfotericina B 0,125 a 0,5mig/ml e fluconazol 2 a 4mig/ml. Todas as cepas de C. albicans isoladas do mamilo de mães que estavam amamentando mostraram a enzima fosfolipase, que pode ser um importante fator de virulência, e apresentaram uma excelente susceptibilidade aos antifúngicos testados.

Candidiasis, human being's main opportunist fungal infection, is caused by Candida, a sort of yeasts which are part of endogenous microflora of the human body. The purpose of this research was to study the Candida species involved in the inflammatory processes of the breastfeeding mothers' nipples from the human milk bank on Assis Chateubriand maternity-school at the Universidade Federal do Ceará, Brazil. It was verified the enzymatic activities and the susceptibilities to the main used antifungal agents in candidiasis. The samples were collected from the wounds in the nipples and grown in Sabouraud agar at 37°C for 72 hours. They were identified by mycology tests. Proteinasis, phospholipase and hialuronidase tests were also made. Amphotericin B and fluconazole susceptibility tests, too. From the 29 samples, 13 (44. 8%) of the total presented growth; 11 (84.6%) of them were Candida albicans; 01 (7.7%) of them was C. stellatoidea and 01 (7.7%) of them was C. guilliermondii. The C. albicans enzymatic activities were: 100% of strains produced phospholipase; 64% produced hialuronidase and none of the strains produced proteolytic activity. The tested yeasts were susceptive to the antifungal agents tested with minimum inhibitory concentration - 0.125 - 0.5mug/ml for amphotericin B and 2 - 4mug/ml for fluconazol. All the C. albicans strains isolated from the breastfeeding mothers' nipples showed the phospholipase enzyme which can be an important virulence factor. They presented excellent susceptibilities to the antifungal agents tested.
