“…Discontinuities in the distribution of Histoplasma capsulatum have been reported among bat colonies in both Trinidad (Ajello eta!. 1962) and Panama (Klite and Diercks 1965). The obvious difficulty in interpreting these types of data is that the discontinuities in distribution could be due to factors other than socially induced barriers to transmission.…”

The intestinal protozoan faunas of 11 social groups of Cercocebus albigena, 3 groups of Ceropithecus mitis, 3 groups of Cercopithecus ascanius, 2 groups of rain forest and 4 groups of savannah Papio anubis are documented. All individuals in a particular social group exhibit identical protozoan faunas. All social groups of each species, except the savannah P. anubis, exhibit intergroup differences in the composition of their protozoan faunas. The number of intestinal, protozoan species in Cercocebus albigena social groups is a function of group size. The similarity between the protozoan faunas of different C. albigena groups is related to the density of the social groups and types of land tenure in particular localities. Past social history of C. albigena groups may have some influence on the level of similarity of different groups' faunas. Entrance of a nongroup member into a group of Cercopithecus mitis resulted in an increase in the species richness of the group's protozoan fauna. Group fission may result in reduction of a group's protozoan species richness. All groups of savannah Papio anubis exhibit identical protozoan faunas. I argue that this is because savannah P. anubis has a higher rate of exchange of individuals between groups than has been recorded for the rain forest primates under consideration. I hypothesize that the differing rates of exchange are due to disease—related selection against traits which result in high rates of individual exchange among rain forest primate groups. Primate social groups are functionally biological islands; the species of their protozoan faunas changes according to group size and levels of protozoan migration between groups.

“…The fungus frequently occurs in soil enriched with bird guano and in caves occupied by colonial bat species (Hasenclever and Piggott, 1974). Birds do not appear to be infected with H. capsulatum, but viable cells have been isolated from various organs from different species of bats and from their gut contents (Klite and Diercks, 1965; M. L. .…”

“…Following the discovery of natural Histoplasma capsulatum var. capsulatum infections in many species of bats [2,10,19] and their proven role in the ecology of this pathogen, a similar role for bats in the ecology of B. dermatitidis was suspected [13]. A large number of bat species have been investigated for dimorphic pathegenic fungi [1,6] but the results were negative for B. dermatitidis, However, it has been experimentally shown that one species of free-tailed bat.…”

Isolation ofBlastomyces dermatitidisfrom the lungs of a bat,Rhinopoma hardwickei hardwickeigray, in Delhi

1982

The isolation of Blastomyces dermatitidis is reported from the lungs of one of 155 insectivorous bats, representing Rhinopoma hardwickei hardwickei Gray, inhabiting the abandoned first floor of a school building in Old Dehli. The identity of the fungus was based on its gross and microscopic cultural morphology including demonstration of its dimorphic character. It was further confirmed by determination of the capacity of the isolate to produce the "A" exo-antigen specific for B. dermatitidis and by verification of its pathogenicity for white mice. Heretofore, B. dermatitidis has not been reported from bats. It is also the first occasion that B. dermatitidis has been isolated from animal sources in an Asian country, thereby indicating that this important dimorphic pathogenic fungus is endemic in Asia.Literature reviews on systemic mycoses in India [14-16] do not reveal any welldocumented case of blastomycosis in man or animals. Moreover, no comprehensive investigation has been undertaken on the natural reservoirs of Blastomyces dermatitidis and other dimorphic pathogenic fungi in this country.This prompted us to initiate a survey of these fungi in bats and bat guano in a number of roosting sites in Delhi. In this preliminary paper, we report for the first time the isolation of B. dermatitidis from a bat and that too from a geographic region where the endemicity of blastomycosis had not been previously recognised. MATERIALS AND METHODS The bats:One hundred and fifty-five free-tailed bats belonging to Rhinopoma hardwickei hardwickei Gray, an insectivorous species, were investigated over a period of 8 months commencing in September, 1980. The bats were trapped from a colony inhabiting the first floor of an abandoned portion of the building of a Girls' Higher Secondary School situated about 1 km south-west of the Administrative Block of the University of Delhi. This was an old building with several dark and dingy galleries and cupolas in its first floor. The bats had been roosting there for many years, as was apparent from the size of the heaps of bat guano which were present. Bats were trapped and brought alive in cages to the laboratory for isolation of pathogenic fungi. The building site fails under the jurisdiction of Old Delhi and it is close to a ridge that supports dense vegetation and wildlife, apart from having some historical monuments.
