Eggs taken from the oviducts of mice, inoculated 3 weeks previously with Mycoplasma pulmonis in the peritoneal cavity, were shown to be contaminated, and mycoplasmas were not eradicated by washing the eggs three times. Zona-free eggs were also infected. Embryos cultured for 24 hours in medium M16 were clear of infection. Sperm from infected males was not(More)
Sweat glands from the palm of a patient with hyperhidrosis were examined by light and electron microscopy before and after treatment with tap water iontophoresis. No changes in structure were noted after treatment, disclaiming the currently accepted theory that mechanical ductal obstruction is the mechanism of action of this method. Furthermore, we believe(More)
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(More)
BACKGROUND With the emergence of multidrug-resistant (MDR-) and extensively drug-resistant tuberculosis (XDR-TB), surgery, which had been replaced by short-course chemotherapy, is again being considered a viable treatment option. OBJECTIVE To assess the literature on the effectiveness of surgical interventions in the treatment of drug-resistant TB. (More)

A mycoplasma isolated from human spermatozoa and a human cervix was shown to be serologically distinct from 98 previously recognized Mycoplasma and Acholeplasma spp. Six mycoplasma colonies were cloned and examined in detail for morphology, growth, and biochemical characteristics; five of these were from sperm samples and one was from a cervix. These(More)
Patients attending an "In Vitro Fertilization" clinic were shown to be commonly infected in the semen with Ureaplasma urealyticum (29%) and Mycoplasma hominis (12%). Other mycoplasmas were rarely recovered. M. hominis was not eradicated from sperm by washing, although washing removed 71% of the ureaplasmas from infected semen. There was a significantly(More)
Organisms isolated from commercial foetal bovine serum and from cell culture lines containing such serum supplements were found to consist of non-helical, non-motile, pleomorphic coccoid forms. One strain (FC 097-2T) cultivated directly from foetal bovine serum was selected for characterization. In ultrastructural examination, individual round cells lacked(More)
We investigated the organisation of working memory processes by examining how a secondary memory task interferes with the accuracy of memory-guided saccades. A target was flashed at a random location, followed by a Kanji character. Subjects had to remember the location of the target and the Kanji character, and then they had to make a saccade towards the(More)
