vulnerability. The fact that these people share the environment with animals promotes the establishment of zoonotic parasitic infections, as well as the resultant parasitic cycles. Thus, parasites present in the environment must be identified, so that control measures can be recommended. In this context, this study’s objective was to evaluate environmental contamination by parasitic forms in a socially vulnerable community in southern Rio Grande do Sul. A total of 100 soil samples collected from the community were processed by a sodium dichromate centrifuge-flotation technique and analyzed by a compound microscope (40X objective) for the identification of parasite eggs, oocysts and cysts. All points were positive for two or more parasites, with the identification of 33.59% non-identified coccidian oocysts, Strongylida (25.4%), Ascaridida (21.31%), Trichuris spp. (8.19%), Toxocara spp. (3.27%), Amoebas (4.08%), Dioctophyma renale (2.45%), and Giardia spp. (1.63%). The presence of parasitic forms in all points analyzed surpasses other studies of environmental contamination carried out in the southern region of Brazil. In addition, the identification of several parasitic forms with zoonotic potential is concerning, since it shows the possibility of parasitic transmission to humans and other animals. In view of the results, the conclusion is that the environment analyzed is contaminated by parasitic forms, constituting a serious public health problem. Therefore, implementing educational and preventive measures in the community to control parasites is of crucial importance.

50 specimens of the Mullets Mugil cephalus were collected from the Libian coastal waters near Misurata city in Libya. 7 different species of trematodes isolated from the intestine of the mullets were briefly described. Haploporus benedenii, Haploporus lateralis, Lecithobotryes putrescens, Saccocoelium tensum, Saccocoelium gohari, Haplosplanchnus caudatus and Haplosplanchnus pachysomus. It is worthy to mention that, the present work is reported for the first time in Libya

Toxocara canis and Toxocara cati are roundworms of dogs and cats. The purpose of this study was to investigate the infection caused by these ascarids in cats and dogs, using microscopic and molecular analysis methods. Adult ascarids were gathered from the faeces of dogs and cats in Van province, in 2015–2016. Existing keys and PCR sequencing of the ITS-2 fragment were used to identify the morphological features of the parasite species. It was observed that out of 20 adult ascarids, 17 and 3 were found to be Toxocara canis and Toxocara cati, respectively. The ITS-2 gene region was amplified by PCR to perform molecular analysis. Genotyping indicated that the dogs and cats were infected with T. canis and T. cati, respectively, and none had Toxascaris leonina. To the best of our knowledge, this is the first report on the molecular characteristics of adult ascaridoid nematodes from cats and dogs in Turkey. The molecular approaches established in this study enable molecular identification and genetic structure studies of the ascaridoids.

This study consisted in histopathological and immunohistochemical examinations of the central nervous system of 15 sheep suspected of infection with Coenurus cerebralis. The sheep displayed compulsive circling and were submitted for necropsy in 2012–2016. Species identification was made on the basis of the PCR analysis and parasitological examination of the cysts. Coenurus cerebralis cysts were detected only in the cerebral tissue of 13 sheep and in the cerebral and cerebellar tissues of 2 animals. Out of the 33 parasite cysts, most (21.21%) were located in the right and left frontal lobes of the cerebrum. The largest cyst measured 6 × 5 cm and the smallest cyst was 2 × 2 cm in size. The highest and lowest numbers of scolices were 55 and 21, and the number of rostellar hooks ranged between 22 and 30. Histopathological examination revealed the presence of typical parasitic granulomatous inflammatory foci. Immunohistochemical staining showed that most common in the periphery of the parasite cysts were, in descending order by cell number, GFAP, CD163, CD3, and CD79α-positive cells. The study confirms the role of cellular defence mechanisms in the pathogenesis of Coenurus cerebralis infection in sheep.

Taenia solium is a parasite causing porcine cysticercosis and human taeniosis and cysticercosis, parasitic zoonoses with a serious public health and economic influence. It has been globally ranked as the top foodborne parasite by the Food and Agriculture Organisation of the United Nations (FAO) and the World Health Organisation (WHO). This parasite is transmitted mainly in countryside regions where animals are free roaming, having access to human faeces, and infected pork is widely available. More developed countries eliminated cysticercosis; nonetheless, there are insufficient data about the current endemicity status of T. solium, due to increased human migration from endemic areas. Formally submitted statistics on cysticercosis in pigs are extremely inadequate. This is the result of not reporting all cases of the disease by some countries and lack of molecular verification during identification of the parasite. There is a need to develop diagnostic tests with increased sensitivity and specificity. The purpose of the present review is to summarise current knowledge about diagnostic and control methods concerning T. solium infection. The article does not address the diagnostics of human cysticercosis, since there is a distinct medical field which should be discussed separately. The paper focuses mainly on identifying the sources of T. solium infection, presenting the methods to detect and control porcine cysticercosis and taeniosis in humans.

This study was carried out to investigate the gastrointestinal helminthes of dogs in Udgir area. Materials and This study consisted of 218 dogs over period of 10 months. A total of 218 faecal samples collected over a period of 10 months from dogs in Udgir area were subjected to fecal sample examination by standard parasitological procedures.An overall prevalence to the tune of 31.65% was noted. The major helminthes parasites recovered were Ancylostoma caninum (66.67%), Ancylostoma braziliense (4.35%), Toxocara canis (26.08%) and Dipylidium caninum (2.89%).There were non-significant differences in age wise and sex wise distribution of helminthes infecting dogs of the area.

Stray dogs are carriers of several zoonotic diseases such as leishmaniasis and canine monocytic ehrlichiosis (CME) as a result of poor nutrition, low hygienic conditions and lack of veterinary care. Thus, the Veterinary Research Institute (VRI) conducted a survey to determine the parasite pathogens such as blood protozoans, gastrointestinal parasites and ectoparasites in stray dogs with the collaboration of the Kuala Lumpur City Council Pest Control Unit. Skin, organ, faecal and blood samples were analysed and results indicate that Babesia canis, Babesia gibsoni, Ehrlichia canis, Hepatozoon canis and microfilaria of Dirofilaria immittis are the common parasites species found in the blood and organ samples in 2014. The faecal floatation technique showed the presence ofhelminth ova such as Trichuris, Ancylostoma and Toxocara species. All skin samples were positive for Rhipicephalus sanguineus ticks. As strays are closely linked to human habitats such as market and housing areas, it is vital that stray population control is strategically implemented to safeguard these common zoonotic infections from spreading to humans.

This case report describes paramphistomosis from the rumen ofan infected 3-year-old Bos indicus or also known as Zebu cattle that was sent to the Veterinary Research Institute (VRI), Ipoh,Perak for post-mortem examination with a history of a sudden death. On post-mortem, it was found that the rumen contents hada large number of pink, pear shaped flukes, which measured about 1 cm in length attached to the rumen wall. On performing the sedimentation technique on the rumen contents, operculated eggs with germ cells were observed microscopically under compound microscope with a magnification of 100×. Regular screening of cattle for flukes is an important part of parasite controlprogrammes especially in endemic areas as it can cause anaemia and deterioration in body condition.

Wild rats are known as a major reservoir and intermediate host for several pathogenic microbial species. Thus, theVeterinary Research Institute (VRI) conducted a survey to determine the presence of parasitic pathogens in local rats, such as blood protozoans, gastrointestinal parasites, as well as ectoparasites such as mites and lice. The study was conducted with the collaboration of Kuala Lumpur City Council Pest Control Unit, whereby a total of 105 wild rats were trapped at two urban areas of Kuala Lumpur; namely PasarPudu and Chow Kit. Autopsy was done on the rats to acquire the skin, organ and blood samples..The skin scrapping was performed on skin samples to identify the common species of mites and lice, while the floatationtechnique was conducted on faecal samples to identify helminth eggs. Results showed thatspecies of Tritrichomonas, Strongyloides, Nippostrongylus, Blastocystis, Rodentolepis, Coccidia, Trichuris, Capillaria and Ascarid were found in the faeces while Trypanosoma sp.was found in the blood samples taken from the animals. Taeniataeniformis was obtained from liver samples while theectoparasites found on skin were identified as Radfordia,Polyplax,Linognathus and Hoploplurasp. Control and eradication of rodent pests is crucial in combating emerging and re-emerging diseases which may be zoonotic as rodents are reservoirs to various pathogens.
