Elastofibromatous change is a benign process that has been increasingly recognized in the tubular gastrointestinal tract. These changes can present as a colonic polyp or be seen in conjunction with inflammatory changes. Similar lesions have been noted in the liver, apparently associated with vascular injury. We describe a case in which multiple circumscribed nodules of elastofibromatous change within the pancreas had a similar morphology to nodular elastosis of the liver. To our knowledge, this is the first description of such a finding occurring within the pancreas.

ABSTRACT An in vivo experiment was performed with pigs to study the inhibitory effect of fermented feed on the bacterial population of the gastrointestinal tract. Results demonstrated a significant positive correlation between pH and lactobacilli in the stomach contents of pigs in dry feed as well as in the stomach contents of pigs fed fermented feed. Furthermore, a significant positive correlation between the pH and the numbers of bacteria in the familyEnterobacteriaceae in the contents of the stomach of pigs fed dry feed was found. In the stomach contents of pigs fed fermented feed, a significant negative correlation was found between the concentration of the undissociated form of lactic acid and the numbers of Enterobacteriaceae. The numbers ofEnterobacteriaceae in the contents of the stomach, ileum, cecum, colon, and rectum of pigs fed fermented feed were significantly lower compared with the contents of the stomach, ileum, caecum, colon, and rectum of pigs fed dry feed. The numbers of total lactobacilli were significantly higher in the stomach contents of pigs fed fermented feed and in the ileum contents of one pig group fed fermented feed compared with the contents of pigs fed dry feed. However, the influence of lactobacilli on numbers of Enterobacteriaceae could not be demonstrated. It was concluded that fermented feed influences the bacterial ecology of the gastrointestinal tract and reduces the levels of Enterobacteriaceae in the different parts of the gastrointestinal tract.

Facultatively anaerobic bacteria, capable of fixing N2 anaerobically or at low O2 concentrations, were isolated from the gastrointestinal tracts of temperate (Strongylocentrotus droebachiensis) and tropical (Tripneustes ventricosus) sea urchins. Morphological and biochemical characteristics, as well as the guanine plus cytosine content of their DNA (45.9 and 48.4 mol%), place these isolates in the genus Vibrio Pacini 1865 in the family Vibrionaceae. Members of this family have not previously been shown to fix N2. These isolates are not identical to any described species in the Vibrio genus and can be distinguished by a combination of biochemical and physiological traits.

New scientific data on the modern epizootic situation on helminthoses of sheep of the breed Edilbayevskaya introduced on the territory of Altai region are provided. To study the contamination of animals with helminths, ovoliroscopic methods commonly used in parasitology were applied. In total 889 fecal samples received from sheep of different gender and age groups are investigated. Gelminthocomplex of animals is characterized by a variety. Tapeworms include parasites of the suborder Anoplocephalata, the family Anoplocephalidae, the genus Moniezia (M. brodeni, M. expanza) and the family Avitellinidae of the genus Thysaniezia (Thysaniezia giardi). Roundworms belong to the Strongylata suborder and are represented by 4 genera nematodes – Nematodirus, Ostertagia, Hemonchus, Oesophagostomum. The infection of lambs with helminths, including Nematodirus spp. and Moniezia spp. in 1.6–3.8 times more than at adult animals also makes respectively 48.1; 42.9 and 15.8%. A distinction of the sheep hermitage of the breed Edilbaevskaya is the low level of infection of animals with strangulates of the gastrointestinal tract, including esophagostomies (0.19%), ostertagies (1.3%), and hemones (0.2%). The dominating and subdominating components of helminthocomplex are Nematodirus spp. and Moniezia spp. For the first time the Skrjabinema ovis is registered in territory of Altai region.

Scarabiasis or Canthariasis or Beetle disease is an ectoparasitic infection of the gastrointestinal tract, in which the beetles temporarily infest the digestive tract and rarely the urinary tract. Dung beetle belongs to Scarabiaediae family.  It is mostly seen in children aged between 2 to 5 years, who play outdoor for prolonged hours without undergarments. It is a temporary infestation in which early stages of development of beetle takes place in the anus and the adult beetle flies, out of the anus while defecation. A boy aged 3 years and four months presented to the pediatric OPD with complaints of peri umbilical abdominal pain, vomiting, nausea, mucus in stool along with “black insects” in his stool. The clinical examination revealed that the pulse rate, blood pressure and temperature were normal. Per rectal examination and ultrasound of the abdomen was normal. Routine examination of stool and urine was also found to be normal. The beetle was identified by the medical entomologist as dung beetle belonging to family Scarabidae. This report implies that the boy had an infestation with the larvae of dung beetle in the gastro intestine. The family belonged to the high range area of Mundakayam. Agriculture is the main source of income for people and main plantation being Rubber. Natives breed cattle for their livelihood and agriculture. During contact with mud or while playing outdoors naked, he would have come into contact with the eggs or the beetle, which hatched into larvae and caused canthariasis.

The Egyptian concept of medicine was complex and related to a widespread religious belief that combined the worship of gods and the medical arts. The healing properties of food, and especially mother’s milk, were well‑known and endowed with divine qualities. Half‑female‑half‑cow Hathor was usually depicted with cow horns and the sun between them. Since medicine and magic were tightly linked, the omens, facts, conscious and unconscious assumptions merged with a mystical mosaic that formed a volatile but honorable system that is currently regarded as a medical art. Supernatural powers were taken into account, and the meaning of art was associated with the powers attributed to the deities. Despite their obvious social and religious‑political experience, the Egyptians had limited knowledge of the internal structure of human body, paying considerable attention to magic, mysticism and afterlife. They deeply believed that most of the diseases originated in the intestines due to their «contaminated» contents. The main problem in understanding diseases and developing their treatment in ancient Egypt was the restrictions associated with the prohibition of body’s desecration. This was based on the assumption that if the shape of the body is not preserved at the time of resurrection, the soul can be lost in void. Thus, the ancient Egyptians were especially concerned with the preservation of body, believing that desecration by animals or worms could also lead to the complete loss of remains for the soul. In the society of Ancient Rome, illuminated only by the flame of fire and the thirst for knowledge, the enjoyment of food and the continuation of the family were of great importance. Unsurprisingly, the ancients respected the sensations of eating. Thus, such exquisite dishes as lark tongue, black caviar, ostrich brain, Falernian wines at the time of Emperor Heliogabalus evoked a unique complex of sensations during eating. Examples of ancient Roman medical tools, including mirrors, found in the house of a surgeon from Pompeii (72 — 62 BC), prove the early tendency to visualize human insides. The qualification of the ancient masters of medical tools is confirmed by the fact that the principles used two thousand years ago have changed slightly. Thus, there were initial concepts of nutrition, digestion, diseases of the digestive tract, and even the rudiments of diagnosing these diseases in Ancient Egypt and Ancient Rome. They served as the basis for the further development of gastroenterological science.

AbstractThe family Deletrocephalidae consists of three species, from two genera: Deletrocephalus dimidiatus, D. cesarpintoi and Paradeletrocephalus minor, which differ from one another in terms of the buccal capsule structure, the dorsal ray from the male copulatory bursa and the length of the vagina in the female. All these species are parasites of the gastrointestinal tract of the rhea, Rhea americana. Only D. dimidiatus was reported to be a parasite of the other rhea species, Darwin's rhea, R. pennata. Currently, there are no studies on the ultrastructure and biology of these parasites or their pathogenicity in these birds. Thus, the present study aimed to examine the ultrastructure and add more details of the morphology of D. dimidiatus from R. americana. Four adult rheas were necropsied, and the gastrointestinal tract was collected and examined for the presence of parasites. Nematodes were analysed by optical and scanning electron microscopy (SEM). All birds were parasitized by D. dimidiatus. Some morphological and morphometric characters were observed that differ from reports of other studies of this species by other authors. In addition, new details were added, well described by SEM, and a key to the species of the subfamily Deletrocephalinae is given.

Guts of ruminants contain symbiotic domains (Eubacteria, Archaea and Eukarya) that aid in the breakdown of consumed carbohydrates from plants to simple molecules that can be absorbed into the ruminant’s bloodstream. Methanogenesis occurs during the gut fermentation and methane gas is released in the final step of biomass degradation from the fermentation chambers. The Archaea that play a major role critical for methane emissions are methanogens and are found freely in the ruminants’ gut. Methane production from ruminants has attracted global attention due to their input on the Green House Gases effect, contribution to global warming and negative effects on farmers’ productivity. The objective of this study was to determine the factors contributing to the methanogens’ gut distribution in dairy cows from smallholder farms using next generation sequencing techniques. A total of 48 samples from smallholding dairy farms were used during this study and were collected from Kenya (Kiambu county) and Tanzania (Lushoto and Rungwe). The collected data samples from the experimental animals were from both the rumen fluid (6) and fecal (42). Samples were analyzed using metagenomic approaches and statistical analysis was undertaken using IBM SPSS statistics software version 28.0.0.0. Results showed that the gut site along the gastrointestinal tract and the feeding regime significantly contributed to the distribution and presence of various methanogenic species (P<0.1). The herd and the genotype had no statistical effect. A total of 12 families were identified. The family Methanobacteriaceae was identified with the leading number (8) of the methanogenic species. A third of the identified families showed presence for at least two methanogenic species with Methanobrevibacter ruminantium being abundant. For proper curbing mechanisms, efforts to reduce methane release should be channeled to the whole gastrointestinal tract and advanced studies carried out on any potential interspecies presence facilitation and/or elimination.

This review describes infections caused by Escherichia coli and related members of the family Enterobacteriaceae, excluding other genera that principally cause enteric infections. Infections caused by Salmonella, Shigella, and Yersinia are described in the review “Gastrointestinal Tract Infections," found elsewhere in this publication. The purpose of this review is to examine the specific epidemiology, clinical manifestations, and treatment of individual members of the Enterobacteriaceae. The emerging concern of antimicrobial resistance amongst enteric gram-negative organisms and the approach to treatment in the setting of infection with these resistant organisms are discussed in the review “Antimicrobial Resistance in Enteric Gram-Negative Organisms,” found elsewhere in this publication. Figures illustrate the mechanisms of antimicrobial resistance in Enterobacteriaceae. A table lists the clinical, epidemiologic, pathogenetic, and therapeutic aspects of infection with various pathotypes of Escherichia coli. This review contains 6 highly rendered figures, 1 table, and 79 references.

The purpose of the research is study of pinniped helminth fauna in Chukotka, and the analysis of the fish of the main commercial families infected with pathogens of helminthozoonoses based on modern literature.Materials and methods. The helminths were collected in autumn of 2019 from pinnipeds caught in the Mechigmenskaya Guba of the Bering Sea in the Chukotka Autonomous Okrug by the method of partial helminthological dissection per Skryabin (gastrointestinal tract). Samples were examined from 6 walruses and 26 seals (13 spotted seals and 13 ringed seals). The helminths found were fixed in 70% alcohol. The helminth species were identified at the Department of Parasitology and Veterinary and Sanitary Examination of the MVA named after K. I. Skryabin using reference literature.Results and discussion. All pinnipeds were infected with nematodes of the family Anisakidae. Mature Pseudoterranova desipiens were found in the walrus (Infection Prevalence = 16.7% with Infection Intensity = 3 specimens/animal), mature Ps. desipiens, as well as Contracoecum osculatum and Anisakis simplex larvae (IP = 30.8% with II from 5 to 57 specimens) were found in the spotted seal, and Ps. desipiens larvae and mature Ps. desipiens were found in the ringed seal (IP = 15.4% with II from 1 to 4 specimens). Thus, only Ps. desipiens were represented by mature stages (females and males), and two other species of anisakids, C. osculatum and A. simplex, were found in the seals in the larval stage.
