The genetic control fo isozymes from Citrus and its near relatives was determined for three gene/enzyme systems: glutamate oxaloacetate transaminase, phosphoglucose isomerase and phosphoglucose mutase. These enzymes are controlled by four genes having 19 codominant alleles, 12 of which occur in Citrus subg Citrus. Formal genetic studies were carried out with F1 biotypes and F1 populations of known origin. When biotypes were grouped into traditionally recognized species to examine genetic affinities within and between species, a remarkable patterm of uniformity of genotype combinations was found within a species, and every species had an unique combination. Because many economicaly important cultivars produce asexual(nucellar) as well as sexua(zygotic) embryos a central problem of the breeder is to distinguish these when plants are young, long before fruiting. Isozyme markers can be used with varying degrees of efficiency, depending on the genotypes of the particular parents, to distinguish nucellar seedlings from those of zygotic origin. |

This work was conducted on rats in two premises located in Niterói and Rio de Janeiro, Brazil. One is classified as conventional controlled and the other, conventional. The objective of the present study was to detect the presence of Mvcoplama pulmonis in animals with symptoms of respiratory disease and low reproductive performance. In the conventional controlled premises, 16 rats of Wistar-Furth strain were necropsjed while in the conventional premises necropsy was performed on 12 rats of Hooded Lister strail1. The clil1ical samples of lungs, trachea, oropharynx, middle ear, uterus and ovaries were subjected to culturil1g while the sera were tested for antibody detection. From 28 rats, 57.14% ( 16/28) were culture positive for M. pulmonis, beil1g 81.25% (13/16) from the conventional controlled premises, and 25.00% (3/12) from the conventional premises, The ELISA test was carried out in 20 animals of both colonies. In the conventional col1trolled premises, 92.86% ( 13/14) were positive for M pulmonis, and 7.14% ( 1/14) were suspicious, while in the conventional premises, 100% (6/6) of the samples were positive. The results confirmed that M. plllmol1is was the etiologic agent of the disease that affected the rats under study, and that the ELISA positivity rated higher than culture.
