RESUMEN
A case of abdominal dioctophymosis in a domestic cat was found in San Juan Bautista district, the Peruvian rainforest, in the Loreto department of Peru. The pet went to a veterinary clinic for a routine ovariohysterectomy during which a large nematode was found in the abdominal cavity. The nematode was morphologically identified as an adult female of Dioctophyme sp. A few morphological parameters, such as the vagina distance from the anterior part and the egg size, were different than D. renale. Partial sequences of the cytochrome c oxidase subunit I (cox1) and the small subunit 18S ribosomal RNA genes were compared with the references from public sequence database and showed a genetic identifies of 89.25% and 99.65% with D. renale, respectively. This is the first mitochondrial molecular analysis of a Dioctophyme specimen from South America and the results showed up to 12.5% nucleotide sequence variation in cox 1 gene of D. renale.

INTRODUCTION: In the last years, there was a rising in the incidence of sexually transmitted infections, including proctitis. Infectious proctitis (IP), mainly caused by agents like Neisseria gonorrhea and Chlamydia trachomatis, is an entity that should be considered when patients with suspected inflammatory bowel disease (IBD) are approached, mainly if they have risk factors such as anal intercourse. CLINICAL CASES/DISCUSSION: The symptoms of IP, like rectal blood, mucous discharge, and anorectal pain, may appear in other causes of proctitis, like IBD. Therefore, to establish the diagnosis, it is crucial to take a detailed history and perform a physical examination, with the diagnosis being supported by complementary tests such as rectosigmoidoscopy, histology, serology, and culture. Depending on the etiology, treatment of IP is based in antibiotics or antivirals, which may be empirically initiated. Co-infections, mainly those that are sexually transmitted, and HIV should be tested and sexual partners should be treated, accordingly. In this article, the authors report three cases of IP, referent to three different patients, and review the initial approach required in cases where there is a clinical and/or endoscopic suspicion of this pathology.

Aspergillus fungi can cause serious infections, including intra-abdominal infection, particularly in patients with compromised immune system. Described in the present report is case of 46-year-old female patient who had undergone laparoscopic cholecystectomy (LC) at another healthcare facility. In early postoperative period, she had increasing complaints of swelling, nausea, and vomiting. On postoperative 19th day, she was referred to our clinic with diagnosis of acute abdomen. Surgery was performed with suspected possibility of bile leakage. However, pathological examination of soft, yellow-green mass found in subhepatic space determined it was fungus ball caused by fungi of the genus Aspergillus. Patient was diagnosed postoperative intra-abdominal aspergillosis (IAA).

Pentastomiasis is an emerging snake-borne parasitic zoonosis in the tropics. We describe a molecular and morphological study to diagnose a cluster of asymptomatic abdominal human infections caused by Armillifer grandis. The findings may indicate a silent epidemic in a rural area where severe symptomatic ocular cases with the same parasite species have recently surfaced. Molecular diagnostics are of increasing importance when patient material from remote areas cannot be thoroughly examined locally for logistic reasons.

Hydatid disease is caused by Echinococcus granulosus-a parasitic infestation commonly affecting the liver. Disseminated intra-abdominal hydatid disease may occur following the rupture of the hydatid cyst into the peritoneal cavity causing secondary echinococcosis. We report a very rare case of disseminated hydatidosis involving various abdominal and pelvic organs and causing intestinal obstruction in a female patient. This unusual presentation produced a diagnostic dilemma.
