OBJECTIVES
To investigate the effects of acetic acid on durable Ascaris lumbricoides (A. lumbricoides) eggs to determine the effective concentration of vinegar and the implementation period to render the consumption of raw vegetables more reliable.
METHODS
This experimental study was performed in May 2015 in the Parasitology Laboratory, Faculty of Medicine, Yuzuncu Yil University, Van, Turkey. The A. lumbricoides eggs were divided into 2 groups. Eggs in the study group were treated with 1, 3, 5, and 10% acetic acid concentrations, and eggs in the control group were treated with Eosin. The eggs' viability was observed at the following points in time during the experiment: 0, 10, 15, 20, 30, 45, and 60 minutes.
RESULTS
The 1% acetic acid was determined insufficient on the viability of Ascaris eggs. At the 30th minute, 3% acetic acid demonstrated 95% effectiveness, and at 5% concentration, all eggs lost their viability. Treatment of acetic acid at the ratio of 4.8% in 30 minutes, or a ratio of 4.3% in 60 minutes is required for full success of tretment.
CONCLUSION
Since Ascaris eggs have 3 layers and are very resistant, the acetic acid concentration, which can be effective on these eggs are thought to be effective also on many other parasitic agents. In order to attain an active protection, after washing the vegetables, direct treatment with a vinegar containing 5% acetic acid for 30 minutes is essential.

Ascaris lumbricoides and Ascaris suum are described as helminths that infect humans and pigs, respectively. It is estimated that infection by A. lumbricoides affects about 447 million individuals living in tropical regions of developing countries. However, there is an increasing number of cases of human ascariasis in countries with no recent history of autochthonous infection by A. lumbricoides. In these places, pigs have been incriminated as the main source of human infection. Conventional parasitological diagnosis does not allow species-specific identification, and the real epidemiological scenario of human and swine ascariasis is still uncertain. Therefore, this work presents the application of a species-specific molecular diagnosis, based on the allele-specific PCR methodology (AS-PCR), using the Internal Transcript Space 1 (ITS-1) of the ribosomal DNA, as a target for differentiating between the two species, using DNA obtained from eggs. To validate the methodology, stool samples positive for Ascaris spp, were obtained from 68 humans from seven Brazilian states and from six pigs from the state of Minas Gerais. All samples obtained from humans were genotyped as A. lumbricoides and all samples obtained from swine were genotyped as A. suum. These results are in agreement with the literature, which demonstrates that in most endemic regions, transmission cycles are separate. Therefore, the execution of this work allowed the availability of a useful methodology for the differential diagnosis of the species, which may contribute to the characterization of the real epidemiological profile of human and swine ascariasis, and to the implementation of future control strategies.

Ascaris lumbricoides is a comman intestinal helminths in humans. It is a parasite which commonly affects society with a low socioeconomic status, especially in tropical and rural areas. Ascaris lumbricoides infestation can lead to serious complications because of the mobility of the worms. The parasite can cause a variety of complications like intestinal obstruction, perforation, biliary obstruction, pancreatitis, peritonitis, liver abscess, cholangiohepatitis, volvulus, and gangrene, etc. A 59-year-old female patient hospitalized with the diagnosis of mesenteric ischemia was operated on for jejunal resection. On the 6th postoperative day, a worm was noticed emerging through the nasogastric tube. Ascaris lumbricoides was determined as a result of the examination microbiology laboratory. The patient was treated successfully with one dose of albendazole 200 mg 1x2. Our case describes a clinical situation of ascariasis observed after jejunal resection and emphasizes the importance of remaining aware of this rare complication of ascariasis.

The relationships between Ascaris lumbricoides worm burden, growth status, general delayed cutaneous hypersensitivity (DCH) response, and plant anthelmintic use were investigated in a 12-mo prospective survey of 663 children, 4-10 yr old, living in the Ranomafana rainforest, Madagascar. Initial fecal examinations revealed prevalences of 93% for A. lumbricoides, 55% for Trichuris trichuria, and 27% for hookworm. After anthelmintic treatment and a 12-mo reinfection period, 428 of the children participated in worm expulsion studies using pyrantel pamoate, revealing an overdispersed A. lumbricoides worm population, mean = 19.2 (SD = 20.4). Malnutrition was common with 72% of the children growth stunted, 61% underweight, and 6% wasted. The children were also skin tested to recall antigens for DCH, with 94% reacting. The DCH immune response was significantly decreased in the malnourished children; however, DCH was not reduced in relation to increasing worm intensity. Growth status, growth velocity, and triceps skinfold did not vary significantly in relation to A. lumbricoides worm burden. Traditional plant anthelmintic treatment was effective in significantly reducing worm intensity. This study indicates that, in human communities where the children are predominately stunted, A. lumbricoides does not aggregate in the most malnourished or immunodepressed children.
