Aspectos morfológicos de ciliados de rúmen (Entodiniomorphida, Ophryoscolecidae) revelados pelas técnicas do Protargol e da reação de Feulgen Zoologia
D'Agosto,Marta; Santa-Rosa,Milden Rodrigues de.
The resulls of the protargol's technique and Feulgen's reactions on ciliates of the genus Entodinium Stetn. 1859, Diplodinium Schuberg. 1888. Eodinium Kofoid & MacLennan. 1932, Eudiplodinium Dogiel. 1927 and Ostracodinium Dogiel. 1927 are presented. The ciliates were obtained from samples of bovine's ruminal content.

Associative behaviour and antagonism of bovine rumen ciliate (Protista, Ciliophora) from Zona da Mata, Minas Gerais State, Brazil Zoologia
D'Agosto,Marta; Guedes,Paulo Marcos da Matta.
Aiming at obtaining the community profile and verifying the occurrence of antagonism and association among ciliates, samples of rumen content were analysed in 100 bovines soon after their death. The animals were killed at the Juiz de Fora Municipal slaughter house (Juiz de Fora, Minas Gerais State, Brazil) between August 1996 and May 1997. Ciliates occurred, respectively, in the following percents and samples number: Entodinium Stein, 1859 (50,48; 100), Diplodinium Schuberg, 1888 (5,59; 98), Eudiplodinium Dogiel, 1927 (6,91; 97), Ostracodinium Dogiel, 1927 (9,68; 95), hotricha Stein, 1859 (4,15; 93), Dasytricha Schuberg, 1888 (3,31; 93), Metadi nium Awerinzew & Mutafowa, 1914 (3,06; 90), Eremoplastron Kofoid & MacLennan. 1932 (7,39; 87),...

Evaluation of lugol solution used for counting rumen ciliates Zoologia
D'Agosto,Marta; Carneiro,Maria Elisa.
The present study proposes a modification of the technique described by PURSER & MOIR (1959) for the quantitative evaluation of rumen ciliate based on an adaptation described by DEHORITY (I984). The modifying process includes: the replacement of two drops of brilliant green dye, for at least four hours, by three drops of lugol solution, for at least 15 minutes. It was made a comparative evaluation of these stainings. It was concluded that lugol solution can replace the brilliant green dye showing the following advantages: staining time reduction and subsequent speeding of sample processing; evidence of skeletal plates of entodiniomorphs making its identification easier; improved observation of small ciliates and inconspicuous structures; improved...
