Household cockroaches constitute a significant public health threat due to their capacity of transmitting medically-important parasites and other pathogens. The role of Iraqi household cockroaches as potential vectors of medically-important parasites was evaluated in the present study. Fifty cockroaches (Periplaneta americana) were collected from different dwelling places of Baquba City, Diyala Province during the period from October to December 2022. The contents of their guts and external body surfaces were examined for the presence of medically-important parasites. The overall prevalence rate of parasitic infestation on the external body surfaces was 60.0%, while the overall prevalence rate of parasitic infection in the guts was 56.0%. Based on capture sites, cockroaches trapped in the toilets had more parasites than those caught from kitchens and rooms. Four species of medically important parasites were isolated from the external body surfaces of the cockroaches; three species were identified as protozoa and only one species was helminth. The protozoan parasites were identified as Blastocystis spp. (36.0%), Giardia spp. (14.0%) and Cryptosporidium spp. (4.0%). In addition, five species of medically important parasites were isolated from the gut contents; four species were identified as protozoa and only one species was helminth. The protozoan parasites were identified as Blastocystis spp. (24.0%), Giardia spp. (10.0%), Cryptosporidium spp. (8.0%), and Entamoeba histolytica/ E. dispar (2.0%). Enterobius vermicularis was the only helminth parasite isolated from both gut contents (2.0%) and external body surfaces (2.0%). In conclusion, the results showed that cockroaches were found to harbor intestinal parasites of public health importance and awareness on the potential role of these insects in the transmission of human intestinal parasites needs to be established.

2018
Cockroaches are considered as vectors of different diseases caused by bacteria, fungi, viruses, protozoa and helminthes. The objective of this study was to examine the role of cockroaches as carriers of intestinal parasites in Wolkite town. Cockroaches were collected twice per month from five kebeles and 50 households, from March to April in 2016. A total of 209 cockroaches were collected in this study. In total, 157 (75.1%) specimens were infected with one or more intestinal parasites such as Ascaris lumbricoides, Hymenolepis nana, Taenia spp., Enterobius vermicularis, Strongyloides stercoralis, Trichiuris trichuira, Giardia lamblia, Entameoba histolytica/dispar and hookworm. The most frequent parasites found were Taenia spp. (29.7%) and E. histolytica/dispar (28.7%).

Cockroaches are one of the ubiquitous insects around human residential areas and their filthy habits make them to be potential carriers of pathogens. In this study, we document the potential health risks associated with cockroaches as mechanical vectors of medically important gastro-intestinal parasites in Osogbo, Southwestern Nigeria. The body surface and the faecal samples of the cockroaches collected from residential area and hospital vicinity were screened for the parasites between November 2011 and February 2012. Thirteen (23.63%) of the 55 cockroaches collected in residential area harboured gastro-intestinal parasites while 16 (35.55%) of the 45 cockroaches from hospital vicinity harboured parasites. Cysts / ova of six gastro-intestinal parasites namely cyst of Entamoeba hystolitica, cysts of Balantidium coli, ova of Ascaris lumbricoides, cyst of E. coli, ova of Enterobius vermicularis and ova of hookworm were encountered in the body surface and faecal samples of the cockroach...

Cockroaches are claimed to be mechanical transmitters of disease causing microorganisms such as intestinal parasites, bacteria, fungi, and viruses. This study assessed the potential of the German cockroach Blattella germanica in the mechanical transmission of intestinal parasites of public health importance. A total of 2010 cockroaches were collected from 404 households in Jimma Town, southwestern Ethiopia. All the collected cockroaches were identified to species as B. germanica. The contents of their gut and external body parts were examined for the presence of intestinal parasites. Overall, 152 (75.6%) of the 210 batches were found to harbor at least one species of human intestinal parasite. Ascaris lumbricoides, Trichuris trichiura, Taenia spp, Strongyloideslike parasite, Entamoeba histolytica/dispar/moshkovski, Giardia duodenalis and Balantidium coli were detected from gut contents. Moreover, parasites were also isolated from the external surface in 22 (10.95%) of the batches. There was significant difference in parasite carriage rate of the cockroaches among the study sites ( = 0.013). In conclusion, B. germanica was found to harbor intestinal parasites of public health importance. Hence, awareness on the potential role of cockroaches in the mechanical transmission of human intestinal parasites needs to be created. Moreover, further identification of the Strongyloides-like worm is required using molecular diagnostics.
Cockroaches and houseflies are serious threat to public health owing to their ability to mechanically transmit human intestinal parasites. The study investigated the role of these insects in transmission of gastrointestinal parasites Ignatius Ajuru University of Education, Port Harcourt, Rivers State. A total of 125 houseflies and 112 cockroaches were caught and screened for possible intestinal parasites. Each housefly and cockroach were dipped into test tube containing 10 ml of normal saline for 5 minutes, the insects later transferred to another test tube with 70% alcohol for preservation. The supernatant were decanted and the residue viewed under microscope for parasites. Data were analysis with analysis of variance, measures of central tendency and least square difference. Results revealed that 32 (25.6%) of the 125 houseflies and 35 (31.3%) of the 112 cockroaches screened harboured parasites of medical importance. Twenty-one (35.0%) of the 60 houseflies caught from eatery area, 8 (20.0%) of the 40 from female hostels and 3 (12%) of the 25 flies from male hostels harboured parasites. Also, 23 (44.2%) of the 52 cockroaches caught from eatery area, 7 (23.3%) of the 30 from female hostels and 5 (16.7%) of the 30 from male hostels harboured parasites. Of these, 20 (62.5%) were protozoa and 12 (37.5%) were helminthes from the houseflies while 19 (54.3%) were protozoa and 16 (45.7%) were helminthes from the cockroaches. The protozoa that were identified include; cysts of Balantidium coli, cysts of Entamoeba coli, Entamoeba Histolytica and Endolimax nana. Also, helminthes include; ova of Ascaris lumbricoides, ova of Enterobius vermicularis and ova of Ancylostoma duodenale and Necator americanus. There was a significant difference (p<0.05) in parasite burden at the eatery and the hostels. There was also a significant difference (p<0.05) in protozoa and helminthes burden from the flies and roaches.

Background: Cockroaches are known to be mechanical vectors of disease-causing agents such as parasites, bacteria, fungi and viruses. This study determined parasitic agents associated with cockroaches in Dutsin-Ma Town, Northwest Nigeria. A total of 600 cockroaches were collected from toilets, dumpsites, suck-away and sewages of Female and Male Hostels of Federal University Dutsin-Ma, residential houses in Darawa, Hayin-Gada and Kadangaru in Dutsin-Ma Town. Aims: To provide the public with this knowledge, this study was put forward to determine parasitic agents associated with cockroaches in Dutsin-Ma Town, Northwestern Nigeria. Study Design: The study was carried out in Dutsin-Ma Local Government Area, Nigeria. Cockroaches collected from the toilets had the highest parasite load, followed by those from the suck-away, and those from the dump site and then cockroaches from the sewages. Results and Discussion: A total of 600 cockroaches (identified as Periplanata americana species) Original Research Article Auta et al.; SAJP, 2(2): 1-6, 2019; Article no.SAJP.46886 2 were examined, 95.33% were infected with several species of gastrointestinal parasites. Parasites isolated and identified include Strongyloides stercolaris (25.26%), fluke (17.89%), Nyctotherus ovalis (2.98%), Enterobius vermicularis (13.68%), Entamoeba histolytica (12.28%), Toxascaris leonina (24.46%). More parasites were recovered from the gastro-intestinal than on the external parts with prevalence rates of 97.33% and 92.67%, respectively. Conclusion: This study has shown that Periplanata americana represent an important reservoir of parasites which can cause disease in man. Hence public awareness is required to educate people on the potential of Periplanata americana in transmitting intestinal parasites thus, there is a need to control cockroaches indoors and outside.
