| Microscopical investigations of the gut contents of six individuals of Dermochelys coriacea from southern England and the North Sea revealed the presence in all of these of numerous nematocysts, mainly scyphozoan. Only six species of Scyphozoa occur in British shallow waters and in the North Sea, viz., Pelagia noctiluca (Forskål), Chrysaora hysoscella (L.), Aurelia aurita (L.), Cyanea capillata (L.), C. lamarckii (L.) and Rhizostoma octopus (L.). For the purpose of comparison and identification an inventory was made of the cnidom of these six species (based on preserved material). Nematocysts of one or more of these species appeared to be present in each of the turtles, all six species being represented. One of the turtles in addition appeared to have... |

| ABSTRACT The fast-growing Brazilian aviculture requires studies to improve zootechnical performance indexes for broiler breeders. The purpose of this study was to assess different feeding programs for broiler breeders on performance and development of digestive organs. A total of 48,000, 1d-old, Cobb 500 broiler breeders were divided into two sheds with 24,000 birds each. The experiment was randomized in block design, considering each shed a block, with 4 treatments and 6 replications per treatment with 2,000 birds in each. Treatments consisted of: Shed 1) T1 = starter feed; T2 = T1 + probiotics; Shed 2) T3 = pre-starter feed; T4 = T3 + probiotics. The productive performance characteristics (bird weight, weight gain, feed intake and feed conversion), the... |

| The adequate diet of Nile tilapia in their growth early stages is fundamental to the success of culture subsequent stages. The goal of the present work was to evaluate the Nile tilapia growth fed with different diets, and to morphometrically characterized the gastrointestinal tract of this species. The treatments consisted of three diets: (D1) natural food, (D2), commercial feed and (D3) commercial feed + natural food. In the qualitative phytoplankton analysis, there was greater representation of the genus Chlorella, while zooplankton community analysis revealed greater number of Brachionus rotifer. Growth and survival in D2 and D3 did not reveal differences (p > 0.05), while in D1, the results were significantly lower (p < 0.05). The... |

| Descriptive studies of the fish digestive system are fundamental because they provide information on the biology of the species. Thus, the objective of this study was to morphologically describe the digestive system of the pufferfish, Chilomycterus spinosus spinosus. For this, adult specimens of pufferfish (n = 10) of both sexes were used. The animals were fixed with 10% aqueous formaldehyde solution, dissected, analyzed descriptively and photographed. The results demonstrate that the pufferfish has a morphologically modified digestive system, which is adapted to the defense behavior. This species presents a pouch-shaped diverticulum, that is called abdominal pouch, which allows the expansion of the celomatic cavity and the temporary storage of food.... |

| This work describes the morphology and histology of the P. argentinus digestive tract. The foregut comprises the mouth, oesophagus, and stomach and is lined by a simple cylindrical epithelium overlain by cuticle. There are tegumental glands in the oral region and in the first portion of the oesophagus and of the hindgut. The cardiac stomach is an oval dorsal sac in the cephalothorax and has no calcified structures. The pyloric stomach comprises an upper chamber and a lower gland filter. The filter consists of an outer row of elongated setae and an inner row of dorsally curved setae forming longitudinal channels 16-18µm wide. The midgut runs from the dorsal chamber of the pyloric stomach to the sixth abdominal somite without caeca. The hindgut runs from the... |

| A survey of the fungal microbiota of the digestive tract of Triatoma infestans (Klug) (Hemiptera: Reduviidae) adults was carried out. Insects captured in the field from different provinces in Argentina, as well as individuals reared in artificial colonies, were used for dissection. Axenic cultures of the fungal species were identified and were deposited with mycological collections at La Plata , Argentina. A total of 33 fungal species, with the exception of three that were mycelia sterilia, belonging to 11 genera were identified. Thirty two species belonged to Ascomycota (Eurotiomycetes and Sordariomycetes) and one to Zygomycota (Zygomycetes). The genera with the greatest number of species were Penicillium (15), Aspergillus (5), and Cladosporium (2). Among... |

| Strict and facultative culturable anaerobic bacteria from the digestive tract of six American black vultures (Coragyps atratus Bechstein 1793) were isolated and identified. After capture, the birds received a non-contaminated diet for one week to eliminate possible allochthonous microorganisms. Then, specimens collected from tongue, stomach and intestines were weighed, submitted to decimal dilution in an anaerobic chamber, inoculated into culture media and incubated aerobically and anaerobically at 37ºC for enumeration, isolation and identification. Isolated bacteria were submitted to tests to detect possible antagonisms between them. The total bacterial population along the digestive tract ranged from 3.46 ± 0.39 log CFU/g in the stomach to 10.75 ± 0.37... |
