However, detailed morphometric studies including mucin histochemistry are scarce. This study compares various GIT measurements as well as the quantification of intestinal mucin secreting cells in four insectivorous bat species representing four different families of Chiroptera. Alcian blue\/Periodic acid Schiff's stain was used to differentiate between acid and neutral mucin\u2010secreting cells while the Aldehyde fuchsin\/Alcian blue stain further differentiated between two acid mucins, namely sialo\u2010, and sulphomucins. The number of cells was quantified and statistically analysed. All species had a simple GIT morphology represented by a simple, completely glandular stomach and the absence of a cecum. The exception was <jats:italic>R. hardwickii<\/jats:italic>, where a small cecum was observed which had histological mucosal features of both the small and large intestine. In <jats:italic>R.hardwickii<\/jats:italic>, distal to the cecum, typical colonic mucosal features such as the absence of villi and an abundance of goblet cells were observed. In all four species, the total number of goblet cells increased from the proximal to the distal intestinal regions. Mixed (acid and neutral) mucins dominated the entire GIT of all species. Neutral mucin\u2010secreting cells were observed in the gastric pylorus and proximal intestinal regions in all species. Brunner's glands stained positive for neutral mucins. Exclusively acid mucin\u2010secreting cells were seen in the distal intestinal regions of all species except <jats:italic>N. thebaica<\/jats:italic>. Sulphomucin\u2010secreting cells were the most prominent acid mucin cell\u2010type towards the distal intestine. The distribution of different mucin secreting cells indirectly provides information regarding the quality of the intestinal biofilm in the species studied.<\/jats:p>","DOI":"10.1002\/jmor.21004","type":"journal-article","created":{"date-parts":[[2019,5,22]],"date-time":"2019-05-22T14:31:02Z","timestamp":1558535462000},"page":"1106-1117","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["A comparative morphological and histological study of the gastrointestinal tract of four insectivorous bat species: <i>Asellia tridens, Chaerephon pumilus, Nycteris thebaica, Rhinopoma hardwickii<\/i>"],"prefix":"10.1002","volume":"280","author":[{"given":"Mikal","family":"Aylward","sequence":"first","affiliation":[{"name":"Division of Clinical Anatomy, Department of Biomedical Sciences, Faculty of Medicine and Health Sciences Stellenbosch University  Cape Town Stellenbosch South Africa"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Leandrie C.","family":"Beselaar","sequence":"additional","affiliation":[{"name":"Division of Clinical Anatomy, Department of Biomedical Sciences, Faculty of Medicine and Health Sciences Stellenbosch University  Cape Town Stellenbosch South Africa"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Abdulaziz N.","family":"Alagaili","sequence":"additional","affiliation":[{"name":"Department of Zoology, College of Science King Saud University, King Saud University Mammals Research Chair  Riyadh Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nabil M.
