| immunocytochemical study of gastrintestinal endocrine cells in insectivorous bats (mammalia: chiroptera). | the regional distribution and relative frequency of endocrine cells in the stomach and intestine of phyllostomidae: lonchorhina aurita and molossidae: molossus molossus bats were studied immunohistochemically. three types of immunoreactive (ir) endocrine cells--to serotonin (5-ht), gastrin (gas) and enteroglucagon (gluc)--were found in the gastric mucosa and four types of ir cells were identified in the intestinal mucosa. this study showed an interespecfic difference in the regional distribution ... | 2008 | 18833490 |
| [report on natural infection of bats by trypanosomatid flagellates in different municipalities in the state of rio de janeiro]. | this study aimed to evaluate natural infection of bats by trypanosomatids. using blood culturing, 86 specimens from different genera were examined, and 22 samples (25.58%) of desmodus rotundus and lonchorhina aurita were isolated. these results contribute towards knowledge of the occurrence of trypanosomatids in bats in the state of rio de janeiro. | 2008 | 19142454 |
| comparative cytogenetic analysis between lonchorhina aurita and trachops cirrhosus (chiroptera, phyllostomidae). | phyllostomidae comprises the most diverse family of neotropical bats, its wide range of morphological features leading to uncertainty regarding phylogenetic relationships. seeing that cytogenetics is one of the fields capable of providing support for currently adopted classifications through the use of several markers, a comparative analysis between two phyllostomidae species was undertaken in the present study, with a view to supplying datasets for the further establishment of phyllostomidae ev ... | 2009 | 21637449 |
| biological and genetic heterogeneity in trypanosoma dionisii isolates from hematophagous and insectivorous bats. | this study describes the morphological, biochemical, and molecular differences among trypanosoma dionisii isolates from hemocultures of hematophagous (desmodus rotundus; n = 2) and insectivorous (lonchorhina aurita; n = 1) bats from the atlantic rainforest of rio de janeiro, brazil. fusiform epimastigotes from the hematophagous isolates were elongated, whereas those of the insectivorous isolate were stumpy, reflected in statistically evident differences in the cell body and flagellum lengths. in ... | 2020 | 32906826 |
| unusual echolocation behaviour of the common sword-nosed bat lonchorhina aurita: an adaptation to aerial insectivory in a phyllostomid bat? | most insectivorous bat species in the neotropical family phyllostomidae glean insects from ground, water or vegetation surfaces. they use similar and stereotypical echolocation calls that are generally very short (less than 1-3 ms), multi-harmonic and frequency-modulated (fm). by contrast, the common sword-nosed bat, lonchorhina aurita, which has the longest noseleaf in the entire phyllostomid family, produces distinctly different echolocation calls. they are composed of a constant frequency (cf ... | 2019 | 31417705 |
