1. The Preventive Effects of Different Doses of Glucomannan on Experimental Aflatoxicosis in Japanese Quails
ABSTRACT This experimental study was performed to investigate whether there is a protective effect of different doses of Glucomannan using against aflatoxicosis in Japanese quail, and pathological changes and relative organ weights were compared. In the experiment, 60 one-day old male Japanese quails were used as divided into six different groups. Experiment

2. Avaliação de peitos e fígados de frango de corte com lesões suspeitas de aflatoxicose
O Brasil tornou-se o maior exportador e um dos maiores produtores de carne de frango do mundo. No ano de 2006, o setor enfrentou uma crise devido a Influenza aviária, não atingindo a produção esperada. Atualmente isto já não é mais uma realidade, pois o consumo desta carne vem crescendo e o setor, cada vez mais, torna-se automatizado e moderno. O cons

3. Monitoramento de aflatoxinas, fungos toxigênicos e níveis de contaminação em matérias primas e alimentos balanceados. Aflatoxicose natural em cães no estado do Rio de Janeiro / Aflatoxins survey, toxicogenic fungi and contamination level in raw material of balanced feedstuff. Natural aflatoxicoses in dogs of Rio de Janeiro State
The commercial feed constitutes an important element in the pet industry in Brazil. Its composition includes cereal mixtures produced in farms such as sorghum, maize and some oily seeds. All feed destined to pets are supplemented with fats, vitamins, minerals, antirust and flours of diverse origins incorporated in some cases as pellets. When conditions of nu

4. The capacity of Saccharomyces cerevisiae to reduce aflatoxicosis and its effect on the distribution and excretion of AFB13H in rats / Saccharomyces cerevisiae na redução de aflatoxicoses e o efeito na distribuição e na excreção da radioatividade de AFB13H em ratos
Para avaliar o efeito de diferentes linhagens de leveduras, Saccharomyces cerevisiae, vivas, na redução de aflatoxicoses e, contribuir para o entendimento do modo de ação destas leveduras sobre aflatoxina B1 marcada com trítio (AFB13H), foram conduzidos três experimentos. No primeiro experimento, foram utilizados ratos Wistar para investigar o efeito d

5. Saccharomyces cerevisiae em milho armazenado e o efeito na redução de aflatoxicoses. / Saccharomyces cerevisiae in stored corn and the reduction effect of aflatoxicosis.
The utilization of live cells of yeasts - Saccharomyces cerevisiae - as probiotic, and, extracted components of the cellular wall of this yeast, as addictive, to desired functions, have been object of interest, due the promising results until then obtained and, simultaneously, for the excess of biomass of yeasts generated by the etanol and beer industry in B

6. Relationship of Aflatoxicosis to Salmonella gallinarum Infections of Chickens
Aflatoxicosis and Salmonella gallinarum exert their effects on the body weight and mortality of chickens without any interaction.

7. Survey of aflatoxicosis in farm animals.
Over a 22-month period, 278 submissions of farm animals were made to the North Carolina Diagnostic Laboratory for suspected aflatoxicosis, and 94 cases were confirmed on the basis of finding aflatoxin in the feed and the occurrence of bile ductule proliferation. There was an annual variation in the incidence of aflatoxicosis, as well as a seasonal variation:

8. Interaction Between Aflatoxicosis and a Natural Infection of Chickens with Salmonella
Broiler chicks with a natural congenital infection of Salmonella worthington required a lower concentration of dietary aflatoxin (0.625 μg/g) to depress growth than uninfected chicks (2.50 μg/g).

9. Reactivity of aflatoxin B2a antibody with aflatoxin B1-modified DNA and related metabolites.
Aflatoxin B2a (AFB2a) antiserum has been previously used in an enzyme-linked immunosorbent assay (ELISA) for the quantitation of AFB1 and AFB2a. The present investigation examined the reactivity of the antiserum toward those adducts and metabolites of AFB1 believed to play a major role in aflatoxicosis and carcinogenesis. 2,3-Dihydro-2-(N7-guanyl)-3-hydroxya

10. Abnormal concentrations of B vitamins and amino acids in plasma and B vitamins in bile of rabbits with aflatoxicosis.
The dosages of aflatoxin B1 (AFB1) required to produce significant changes in concentrations of B vitamins in plasma and bile and of amino acids in plasma of rabbits were determined. Folate increased by 98% in plasma, whereas concentration of thiamine, vitamin B6, and biotin decreased by more than 50%. In bile, choline and biotin increased 14- and 18-fold, r

11. Effect of dietary aflatoxin on fertility, hatchability, and progeny performance of broiler breeder hens.
The effects of aflatoxin on egg production, fertility, hatchability, and progeny performance were investigated by feeding dietary aflatoxin at dose levels of 0,5, and 10 mug/g to mature broiler breeder hens for 4 weeks. Sixteen hens were used for each dietary dose level. Egg production decreased significantly during weeks 3 and 4 after initiation of toxin fe

12. Abnormal concentrations of B vitamins and amino acids in plasma, bile, and liver of chicks with aflatoxicosis.
Graded levels of aflatoxin fed to broiler chickens for 3 weeks decreased the levels of most B vitamins in plasma, bile, and liver and decreased all free and hydrolyzed amino acids from peptides in plasma. The levels of thiamine, riboflavin, vitamin B6, pantothenic acid, and choline decreased by more than 60% in bile; vitamin B6, pantothenic acid, and choline
