Use of DNA fingerprinting and biotyping methods to study a Candida albicans outbreak in a neonatal intensive care unit.

During a 15-day period, 7 premature infants hospitalized in a neonatal intensive care unit presented with sepsis caused by Candida albicans. The local environment and hands of all 54 persons involved in the intensive care unit were examined for the presence of this organism. Five techniques were used in the analysis of the isolates recovered from blood cultures of the children, the hands of personnel and 10 control isolates. The methods used were serotype determination, genetic fingerprinting, morphotyping, resistotyping and killer yeast typing. Morphotyping and genetic fingerprinting proved to be the most discriminatory techniques, and only combined analysis of the results obtained with these various methods allowed the source of the outbreak to be identified. An isolate from the hands of a healthy staff member and isolates from infected children all belonged to the same strain.

[Keratomycosis, from head injury to aspergillosis].

Keratomycosis due to Aspergillus fumigatus occurs most often in immuno-competent patients who live and work in a fungus-rich atmosphere. Previous trauma with epithelial lesion are reported by most authors. While the new antifungal drugs may be effective, corneal graft is the most effective solution in uncontrolled cases. When performed early, good visual recovery was observed in most cases as reported in the literature and in our case.

[The present status of the conquest of tropical Africa by Pulex irritans Linnaeus, 1758].

Owing to human parasites, two fleas, namely Pulex irritans Linné, 1758 and Tunga penetrans (L., 1758) were brought from America to intertropical Africa. The conquest of Africa by Pulex irritans, was really effective since the fifties, evidently by european strains. Some examples selected in occidental and oriental Africa show the reality of this fact. Accordingly, the epidemiological modalities in plague's african foci can be strongly changed.

[Recurrent fever episodes in an African child: diagnostic difficulties of trypanosomiasis in France].

A young Angolian boy who had emigrated to France at the age of 2, presented with a long history of fever. Gambian Trypanosomiasis was diagnosed with peculiar aspects: 1) evolution of adult sickness with a long hemolymphatic period (first stage) and a subacute worsening period with neurologic deficit and somnolence (second stage); 2) a possible post-transfusional contamination: the young boy, born in South Angola, a nor-highly endemic area, was transfused at the age of 10 months with the blood of a donor who was subsequently treated for Trypanosomiasis; 3) a suppurating adenopathy; 4) a predominance of IgG within the hypergammaglobulinemia while IgM are the predominant immunoglobulins in this affection; 5) a hepatic toxicity of Difluoromethylornithine.

Maxillary sinusitis from Microascus cinereus and Aspergillus repens.

Microascus was associated with Aspergillus repens in a left maxillary sinus. Tissue contained septale filaments of two types, conidia, ostiolate perithecia containing ascospores corresponding to Microascus cinereus which was identified by culture. The abundance of sexual fructifications in the tissue indicates that pathogenicity is due to Microascus cinereus.

[Keratinophilic fungal flora isolated from small wild mammals and rabbit-warren in France. Discussion on the fungal species found].

The occurrence of dermatophytes and other keratinophilic fungi was investigated in 237 small wild mammals and 125 european rabbit. The purpose of the investigation was to determine what were the species of fungi present in the these animals. Four species of dermatophytes were isolated: Trichophyton ajelloi, Trichophyton terrestre, Trichophyton mentagrophytes, Microsporum persicolor. Trichophyton terrestre was the most frequently isolated and it occurred more frequently than its presence could be explained by the contamination from soil. Members of the genus Chrysosporium were found in many animals: Chrysosporium keratinophilum, Chrysosporium tropicum, Chrysosporium multifidum, Chrysosporium pannorum, Chrysosporium georgii, Chrysosporium merdarium, Chrysosporium anamorph of Arthroderma curreyi, Chrysosporium anamorph of Arthroderma cuniculi, Anixiopsis stercoraria, Chrysosporium parvum. Wild small mammals and european rabbits in France, not only act as carrier of keratinophilic fungi and allied dermatophytes but also provide a suitable habitat for their survival as saprophytes. The recurrence of numerous species present on the coat, isolated fort the first time in France was remarkable.

The isolation of Meaban virus, a new Flavivirus from the seabird tick Ornithodoros (Alectorobius) maritimus in France.

Seven strains of a new Flavivirus, for which the name of Meaban virus is proposed, were isolated from the seabird tick Ornithodoros (A.) maritimus collected during 1981 and 1982 in nests of herring gulls (Larus argentatus) on islands of South Brittany, France. The new virus was compared serologically with 65 other flaviviruses including Tyuleniy virus and was found to be most closely related to, but different from Saumarez Reef virus, an agent previously isolated in Australia and Tasmania. Some general properties of Meaban virus are described and its antigenic relationships with other tick-borne flaviviruses associated with seabirds are discussed.

[Human hypodermyiasis in France in 1984: 266 cases recorded to date. Distribution according to known geographic origin].

The authors, after collecting all human hypodermosis cases in France they know to this day, to the number of 266 (cases in the literature, and unpublished, diagnosed or by them, in the great majority, or by others), make the situation, at the beginning of 1984, of this parasitosis and do comments on the evolution in time of the number of cases according to the geographical regions in France.

[Etiologic and epidemiologic questions posed by erythema chronicum migrans and Lyme disease. Apropos of 4 cases at the Regional Hospital Center, Rennes].

The authors give 4 observations, made in Rennes (France), of 3 cases contracted in France and 1 in Canada, cases they think to be related, for 3 at least, to the infectious entity described by American authors under the name of Lyme disease. If 1 of these cases was limited to an erythema chronicum migrans, the 3 others showed a beginning evolution towards a classical Lyme disease. In 2 of these 3 last cases, the infection was perhaps cut short by a quickly applied therapy by antibiotics. They discuss the different hypotheses about the negative Borrelia serologic reactions in 3 of the 4 cases. A possible arboviral aetiology is evocked. In only one of the 4 cases, a tick-bite can be asserted, the role in the the transmission of this kind of arthropods being strictly excluded in 2 of the 3 other cases (transmission likely by a mosquito and by a biting fly (tabanid?)). The authors put the question of the possibility of transmission, for erythema chronicum migrans and Lyme disease, by arthropods other than ticks.

[Arbovirus serological survey among marine and non-marine birds of Brittany].

Sera from 215 seabirds (mainly gulls) and 74 landbirds (mainly starlings) from Brittany were studied by hemagglutination inhibition and complement fixation tests for antibody against 9 arboviruses among them 8 were previously isolated from ticks associated with seabirds. Among seabirds, 145 or 65% were found positive for flaviviruses and nairoviruses of the Hughes serogroup. Unexpected frequency of HI positive reactions for Tyuleniy virus indicate the possible circulation of this virus among seabirds colonies of Brittany in addition to the recently isolated Meaban flavivirus. Among landbirds, only one positive HI reaction for Tyuleniy virus was detected in a house sparrow (Passer domesticus) and it seems that landbirds may not play an important role in the dissemination of these arboviruses to man and to domestic animals.

Observations on the subgenus Argas (Ixodoidea: Argasidae: Argas). 19. Description of the larva of the Palearctic cormorant parasite A. (A.) macrostigmatus.

Larvae of 19 of the 21 species of the Argas subgenus Argas are already described. One of the two exceptions is A. (A.) macrostigmatus; we describe the larva of this species from wet nests of the crested cormorant, Phalacrocorax aristotelis, from Corsica, France. As in the adult and nymphal stages, this larva has an uncovered Haller's organ, a character shared in Palearctic members of this large genus only with A. (A.) polonicus, a Central European parasite of rock pigeons. Available larval samples of both species are indistinguishable. However, adult and nymphal A. (A.) macrostigmatus are unique for their exceptionally large spiracular plates. These are the only Argas (Argas) species which differ distinctly as adults and nymphs but hardly or not at all as larvae. Argas (A.) macrostigmatus was previously known only from a nest of the crested cormorant in the Black Sea. Ukrainian SSR.
