A heifer born to a cow experimentally infected with Brucella abortus strain 544 and reared in isolation from its birth was found infected. Antibodies appeared when it was 10 months old. The heifer calved normally. Brucella abortus of the same characteristics as strain 544 was recovered from a hygroma and from lymph nodes and udder. Five heifers out of 55 (about 10 per cent) born to infected dams and reared in isolation from their birth were found to be infected.

A survey was carried out to characterise the bacterial and mycoplasma flora of a closed colony of marmosets, Callithrix jacchus. Bordetella bronchiseptica and Staphylococcus aureus were the only potential bacterial pathogens isolated from the colony; Candida albicans was also identified. S aureus and C albicans were the only organisms which were associated with macroscopic lesions or overt disease. Post mortem examination of the animals proved only reliable method of establishing the presence of some bacterial species in the colony, eg, B bronchiseptica and of obtaining a reliable estimate of the incidence of the various organisms within the colony. The marmosets were all infected with ureaplasmas in the upper respiratory tract. Mycoplasma salivarium was isolated from this site in several animals. There was no evidence to indicate that cross-infection had occurred between the animal technicians and the marmosets, except in one possible case of candidiasis.

A 9.1 x 10(6)-dalton transposable deoxyribonucleic acid sequence resides within Pseudomonas aeruginosa plasmid R1033 and mediates resistance to gentamicin, streptomycin, sulfamethoxazole, chloramphenicol, and mercuric chloride. Transposability was demonstrated in Escherichia coli when this sequence, designated Tn1696, excised from R1033 and integrated into plasmid pMB8. Excision and insertion of Tn1696 occurred independently of the host Rec phenotype and may involve the 140-base pair, inverted deoxyribonucleic acid repeated region that flanks this sequence. Occurrence of a multiresistance transposon on a transferrable plasmid that has a broad host range may have serious epidemiological and therapeutic consequences.

The effect of R plasmids on spontaneous and radiation (ultraviolet and gamma)-induced mutability in Pseudomonas aeruginosa was studied in strains containing the radiation-sensitive markers polA3 or rec-2 and the revertable auxotrophic markers hisO27 and trpB1. In the absence of an R plasmid, the radiation-induced mutability was dependent on the recA+ genotype and independent of the polA+ genotype, whereas spontaneous mutability was similar in all genetic backgrounds. R plasmids pPL1, R2, and pMG15 increased the ultraviolet radiation survival and ultraviolet-induced mutability of wild-type and polA host cells but did not alter either effect in a recA mutant. These R plasmids also increased the gamma radiation survival and gamma-induced mutability of wild-type host cells bud pMG15 also enhanced the level of spontaneous mutagenesis in wild-type host cells but not in a polA or recA mutant. These data suggested that a common plasmid gene product(s) may participate in various recA-dependent, error-prone deoxyribonucleic acid repair pathways of P. aeruginosa. The properties of a mutant R plasmid, pPL2, originally selected because it lacked enhanced ultraviolet-induced mutability, supported this conclusion.

Four rhesus monkey pituitary glands were examined by transmission electron microscopy. Three types of intercellular junctions, desmosomes, hemidesmosomes and zonula adherens-type junctions, were observed between adjacent granular cells, folliculo-stellate cells, and joining a folliculo-stellate cell with a granular cell. Demosomes were most commonly observed between granular cells while the zonula adherens-type junctions were generally found between the folliculo-stellate cells.

Intact soleus and extensor digitorum longus muscles in the rat were freely grafted to the contralateral leg after either no preliminary treatment or 14 days prior denervation. Normal muscle grafts during the first week were characterized by a central zone of degenerating original muscle fibers (disappearing by 7-9 days) and a peripheral zone, containing regenerating muscle as well as small numbers of surviving original muscle fibers. A radial gradient of regeneration was establihed, with more mature muscle at the periphery and less mature muscle toward the center. Denervated grafts were characterized by rapid degeneration (within 2-3 days) of original muscle fibers in the central area, rapid appearance of regenerating muscle fibers (e.g. cross striations by 5 days) with uniform levels of differentiation throughout the graft and larger numbers of surviving original muscle fibers at the periphery. During the first week, stages of muscle differentiation in denervated grafts were attained 1-2 days earlier than comparable stages in normal grafts. Later stages of muscle differentiation were similar in both types of grafts. Histochemical studies revealed a loss of enzyme activity (phosphorylase, ATPase and SDH) in the center of early (2-4-day) normal and denervated grafts. Denervated grafts, however, possessed a thicker peripheral rim of enzymatically active surviving muscle fibers than normal grafts. In both types of grafts the old muscle fibers in the center were replaced by enzymatically active regenerating muscle fibers which stained uniformaly (ATPase) until 30 days. By 60 days a mixed fiber pattern had developed. Muscle spindles were found within the grafts.
