“…Our findings that E. vermicularis was the commonest parasite detected in the appendix are also in keeping with the notion that gastrointestinal infection because of this helminth occurs worldwide (Mowlavi et al 2004;Dorfman et al 1995). Although sample size was limited for significance, our cases of parasitic infection of the appendix were more commonly seen in children less than 10 years old and in whites than in nonwhites.…”

The association between parasitic infection of the appendix and acute appendicitis has been widely investigated. The aim of this retrospective study was to evaluate the prevalence of parasitic infection of the appendix in a tropical area at southeast Brazil and to assess its possible relation to acute appendicitis in surgically removed appendices. Of the 1,600 appendectomies performed during a 10-year period, 24 (1.5%) were found to have helminths within the appendix. Enterobius vermicularis was observed in 23 of the 24 specimens (95.8%), and Taenia sp. was detected in only one case. Sixteen patients (66.7%) were less than 10 years old; 15 patients were male and nine female; 21 patients were white, and three were nonwhites. Pathologic analysis disclosed acute neutrophilic inflammation in the appendix wall in 12 of the 24 specimens and lymphoid hyperplasia in 10 of the 24 appendices. Gangrenous appendicitis was diagnosed in three cases, and peritonitis was found in 11 of the 24 infected appendices. The results of the present study indicate that E. vermicularis is the commonest worm found in the appendix and that its presence can cause pathologic changes ranging from lymphoid hyperplasia to acute phlegmonous inflammation with life-threatening complications like gangrene and peritonitis.

“…Role of parasitic infection as a co-factor in appendicitis is controversial even though today. There are only a few evidence about the relation between acute appendicitis and parasites (17)(18)(19). Onset of pathogenesis of acute appendicitis may be due to either inflammation occurring secondary to existence of parasites and their ova, or obstruction of the lumen by parasite itself (17)(18)(19).…”

Objective: Assessment of frequency and clinical findings of parasitic infections for etiology of acute appendicitis. Methods: Data of 1452 patients who were carried out appendectomy between January 1999 and December 2012 were analyzed retrospectively. Appendectomy was performed in 1159 of the patients with a pre diagnosis of acute appendicitis. Demographics, physical findings, radiologic and laboratory studies, operative findings, pathological results, presence and type of parasitosis were investigated. Results: Among the 1159 patients done appendectomy with a pre diagnosis of acute appendicitis, 719 (62%) were males and 440 (38%) were females. Parasitic infection was demonstrated in 17 (1.4%) of them. Mean average age of these patients was 36.6±20.1 years. Enterobius vermicularis was present in 15 (88.2%) and Entamoeba histolytica in 2 (11.8%) of the patients. Of the pathology specimens of appendix consisting Enterobius vermicularis, 12 (80%) were normal appendix tissues, 1 (6.6%) was acute uncomplicated appendicitis and 2 (13.3%) were perforated appendicitis. One (50%) of the two specimens consisting Entamoeba histolytica was normal appendix and the other (50%) was acute appendicitis. Conclusion: Differential diagnosis of parasitic infections in etiology of acute appendicitis should be made properly. It must be remembered that this attention can save patients from a negative laparotomy and morbidity and mortality of it.

Abstract. Balantidium coli infection was coprologically studied in 2,124 Aymara children 5-19 years of age from the schools of 22 communities of the northern Bolivian Altiplano over a five-year period. Infection with B. coli was found in 11 of the communities surveyed, with prevalences of 1.0-5.3% (overall prevalence ϭ 1.2%). The prevalences observed are some of the highest reported and did not differ significantly among the various age groups or between boys and girls. These prevalences, the apparent absence of symptoms or signs of illness due to this parasite in the schoolchildren surveyed at the time of stool sampling, and the consistency of stool samples of the infected students suggest that they are apparently asymptomatic carriers. Infection with B. coli must be considered as an endemic anthropozoonosis in the area studied. A relationship between B. coli infection and Altiplanic pigs is suggested.Balantidium coli (Malmsten, 1857) (Ciliophora: Balantiidae) is the largest protozoan and the only ciliate parasite of humans. Although numerous animal species are known to harbor B. coli, pigs have a particularly high rate of infection (20-100%) and consequently are generally considered the main natural reservoir of this parasite.
