In order to determine the prevalence and to characterize the carriage of Microsporum canis in cats, different mycological examinations (including a culture obtained by hair brushing and Wood's light examination) were performed on 632 animals of different origins. Group 1 comprised 467 healthy pet cats belonging to veterinary students. In this group, prevalence of carriage was 2.1%: eight cats were asymptomatic transient carriers and one cat was an asymptomatic infected animal presenting discrete Wood's-positive lesions disseminated on the whole body that were visible after sedation and clipping. The carriage prevalence was higher (15.7%) in group 2 comprising 134 European cats destroyed in a pound and kept together. In two additional groups of cats, it was shown that an infected cat was responsible for the dissemination of fungal material into its environment including the other in-contact animals. When the active source of fungus was removed, the dissemination stopped, resulting in a decrease in the amount of infective material recovered from both the animal carriers and the environmental surfaces. This was also observed in two experimental groups of guinea pigs. No association between feline immunodeficiency virus infection and the M. canis carriage was observed in a retrospective case-control study performed on group 2. None of these cats was feline leukaemia virus positive. [less ▲]

Timing effects of radioimmunotherapy (HIT) combined with external beam radiotherapy (RT) were assessed In human colon carcinoma xe nografts. Initially, dose effects offractlonated RT and RIT were evaluated separately. Then, 30 Gy RT (10 fractions over 12 days) were combined with three weekly Lv. injections of 200 g@Ci of 131I-labeled anti-carcino embryonic antigen monoclonal antibodies in four different treatment schedules. RIT was given either prior to, concurrently, Immediately after, or 2 weeks after RT administration. The longest regrowth delay (RD) of 105 days was observed in mice treated by concurrent administration of RT and lilT, whereas the RDs of RT and RIT alone were 34 and 20 days, respectively. The three sequential combination treatments produced sig nificantly shorter RDs ranging from 62 to 70 days. The tumor response represented by the minimal volume (MV) also showed that concurrent administration of RT and RIT gave the best result, with a mean MV of 4.5% as compared to MVs from 26 to 53% for the three sequential treatments. The results were confirmed In a second experiment, In which a RT of 40 Gy was combined with an identical lilT as above (three injections of 200 g&Ci of ‘31I-labeled monoclonal antibodies). At compa rable toxicity levels, the maximum tolerated RT or BIT alone gave shorter RDs and less tumor shrinkage compared to slinultaneous RT+RIT. These results may be useful for designing clinical protocols ofcombined RIT and RT. [less ▲]

Specific repertoire of olfactory receptor genes in the male germ cells of several mammalian species

Olfactory receptors constitute the largest family among G protein-coupled receptors, with up to 1000 members expected. We have previously shown that genes belonging to this family were expressed in the male germ line from both dog and human. We have subsequently demonstrated the presence of one of the corresponding olfactory receptor proteins during dog spermatogenesis and in mature sperm cells. In this study, we investigated whether the unexpected pattern of expression of olfactory receptors in the male germ line was conserved in other mammalian species. Using reverse transcription-PCR with primers specific for the olfactory receptor gene family, about 20 olfactory receptor cDNA fragments were cloned from the testis of each mammalian species tested. As a whole, they displayed no sequence specificity compared to other olfactory receptors, but highly homologous, possibly orthologous, genes were amplified from different species. Finally, their pattern of expression, as determined by RNase protection assay, revealed that many but not all of these receptors were expressed predominantly in testis. The male germ line from each mammalian species tested ins thus characterized by a specific repertoire of olfactory receptors, which display a pattern of expression suggestive of their potential implication in the control of sperm maturation, migration, or fertilization [less ▲]
