چکیده
We undertook a study of the mechanical transmission of parasitic organisms in cockroaches in the Samutprakarn province of Thailand. In this study, 920 cockroaches were obtained from 18 open-air shopping markets in 5 districts and 1 subdistrict of this province. All cockroaches were captured during their feeding time in their natural habitat. Direct wet smear and modified acid-fast bacilli staining were used to identify the parasites from the external surface or cuticle of the cockroaches. The results show that 498 (54.1 %) of the cockroaches harbored parasitic organisms. Of these, 56.1 % were protozoa and the remaining 43.9 % were helminthes (pathogenic helminthes- 1.4 %, non-pathogenic helminthes- 42.5 %). Of the pathogenic helminthes, the species included Strongyloides stercoralis (6 instances of the free-living adult male, 0.8 %), Ascaris lumbricoides (2 decorticated eggs, 0.3 %), Trichuris trichiura (2, 0.3 %), and Taenia spp. (1 egg, 0.1 %). The protozoa types that were identified included Cyclospora spp. (10 oocysts, 1.3 %), Endolimax nana (10 cysts, 1.3 %), B. hominis (9 instances of the vacuolated form, 1.2 %), Isospora belli (75 oocysts, 9.6 %), Entamoeba histolytica/E. dispar (36 cysts, 4.6 %), Cryptosporidium spp. (220 oocysts, 28.1 %), Chilomastix mesnilli (2 cysts, 0.3 %), Entamoeba coli (31 cysts, 4.0 %), Balantidium coli (45 trophozoites, 5.8 %), and Iodamoeba butschlii (1 cyst, 0.1 %). These results show that cockroaches isolated from these markets are carriers of several parasitic organisms that cause commonly found symptoms of illness such as diarrhea or bowel disorder.

One of the common problems in the medical parasitology laboratory is the differentiation of parasites from other elements in the stool and body fluids so-called "artifacts". Artifacts generally referred to living or abiotic agents that embedded in the clinical sample and may misleading the lab because of their similarity to parasitic organisms. Artifacts are an integral part of the diagnosis pr...

متن کاملCockroach surveys in 14 provinces of Thailand.
Cockroach surveys using sticky traps were conducted in urban areas of 14 Thailand provinces. At least 30 houses in each province were randomly sampled for cockroaches. Each house was trapped in three areas: kitchen, bedroom and outside. A total of 2,648 cockroaches was caught by 550 out of 1,542 traps (35.7%), from 337 of the 514 houses (65.6%). Overall, relative density ranged from 2.6 to 9.1 ...
