“…In the present study, the other detergents and acetic acid also did not interfere in the mortality of A. lumbricoides larvae. However, in the studies of Zanini & Graeff-Teixeira (1995)31 that used the parasite A. costaricensis as a model, the effectiveness of sodium hypochlorite was observed, differently from what was observed in the present study, which did not observe efficacy in the mortality of A. lumbricoides larvae, corroborating with the studies byMassara et al (2003) …”

Introduction: Intestinal parasitic infections represent a public health problem, being responsible for high rates of morbidity and mortality. Ascaris lumbricoides is one of the main parasites prevalent in the community. The A. lumbricoides infection method is oral fecal cicle, in this sense, it is necessary to expand effective methods to prevent the ingestion of eggs, such as sanitation, cleansing habits or even effective methods for the sterilization of eggs. Objective: Evaluate different agents of antisepsis action, with the purpose of find which ones are more efficient in larval mortality inside eggs. Methodology: The parasites were provided by the Federal University of Minas Gerais, which were sectioned, in this way, the recovered eggs were kept in culture bottles. After 40 days the embryonated eggs were purified and separated in culture bottles, and in each bottle had one different disinfectant products were added, in different concentrations and action time. As control, egg aliquots were maintained by adding distilled water. Using a microscope, it was observed the viability of the larvae inside. To determine the viability of the larvae, distilled water at 40 °C was added, then allowing the visualization of mobility inside the eggs. Results: It was observed that, fifteen disinfectant agents tested, only four showed efficacy, at intervals of 24 and 48 hours after exposure to the disinfectant and when undiluted. Conclusion: The data obtained in this study will contribute to the understanding of the epidemiology of this disease, as well as contributing to the development of more effective hygiene programs for the control of this parasitosis.

Abdominal angiostrongyliasis, report of two cases and analysis of published reports from Colombia

et al. 2020

Abdominal angiostrongyliasis is a parasitic zoonosis, endemic in the American continent. Its etiological agent is Angiostrongylus costaricensis, a nematode whose definitive hosts are rats and other rodents and the intermediate hosts, slugs. Mammals acquire the infection by consuming vegetables contaminated with L3 larvae. The disease shows a heterogeneous clinical spectrum and given its low incidence its diagnosis is a great challenge.In Colombia, the first case was reported in 1979 and until 1998, only five additional cases have been reported. However, in the last two decades, no new cases were reported. Here we discuss two cases of children from Huila and Caquetá departments who developed the disease. Both cases required long in-patient care and multiple surgical interventions. The diagnosis was achieved by histopathological observation of parasitic elements inside the mesenteric arteries. One of the children died while the other fully recovered.We discuss the epidemiology, pathogenic cycle, clinical presentation, diagnosis, and prevention strategies of this disease paying particular attention to our patients’ features and the Colombian context.

“…In chronic cases, the patients may present low-grade fever and mild and occasional abdominal pain for several weeks 18 . When evolving to chronicity, the intestinal inflammatory reaction becomes a palpable mass in the right iliac fossa 24 . The clinical picture can be intermittent: the patient may present an alternation of remission periods followed by short symptomatic intervals; at this point, a sub-occlusive condition may occur.…”

“…Such modifications may generate imbalances in the mollusk populations that form the intermediate hosts and, as a consequence of this, generate higher levels of risk for human infection 11 . Preventive measures include careful food inspection and cleaning, especially prior to vegetable consumption 24 . Land snails such as Megalobulimus sp, should be adequately boiled before ingestion and their production must be undertaken in closed breeding settings so as to avoid any contact with feces and rodents; slug fishing baits must also be avoided 11 .…”

The authors describe a case of abdominal angiostrongyliasis in an adult patient presenting acute abdominal pain caused by jejunal perforation. The case was unusual, as this affliction habitually involves the terminal ileum, appendix, cecum or ascending colon. The disease is caused by the nematode Angiostrongylus costaricensis, whose definitive hosts are forest rodents while snails and slugs are its intermediate hosts. Infection in humans is accidental and occurs via the ingestion of snail or slug mucoid secretions found on vegetables, or by direct contact with the mucus. Abdominal angiostrongyliasis is clinically characterized by prolonged fever, anorexia, abdominal pain in the right-lower quadrant, and peripheral blood eosinophilia. Although usually of a benign nature, its course may evolve to more complicated forms such as intestinal obstruction or perforation likely to require a surgical approach. Currently, no efficient medication for the treatment of abdominal angiostrongyliasis is known to be available. In this study, the authors provide a review on the subject, considering its etiopathogeny, clinical picture, diagnosis and treatment.
