Pentatrichomonas hominis and other intestinal parasites in school-aged children: coproscopic survey
AbstractPentatrichomonas hominis (P. hominis) is a large intestinal flagellated protozoan infecting humans. Little is known about the epidemiology ofP.hominis in Egypt, its association with gastrointestinal symptoms and the co-infection with other parasites. Demographic and clinical data were collected from 180 school-aged children. Parasitological examination of fecal samples was done using direct wet mount, formalin ethyl-acetate, Kato –Katz and cultivation on Jones’ medium to detectP. hominis and associated parasitic infection. The diagnosis ofP. hominis was confirmed using Giemsa stain and scanning electron microsc...

Toxocara canis prevalence in soil, dog stool, and human serum samples from a rural village in Los Ba ños, Laguna, Philippines
This study was conducted in a rural village in Los Ba ños, Laguna, Philippines to determine the prevalence of toxocariasis among selected public schoolchildren and identify some risk factors that can contribute to the transmission dynamics of toxocariasis in the study site. To elucidate this, serum samples from 50 public school children (ages 8–13) were tested using aToxocara canis IgG ELISA kit, while 60 randomly selected households were chosen for collection of soil and dog samples. Sixty soil and dog fecal samples were collected and processed through modified sucrose flotation technique and formalin-ethyl acetate con...

Detection of Echinococcus granulosus sensu lato cysts and seroprevalence of cystic echinococcosis in cattle and camels in Maiduguri Abattoir
This study was conducted to determine the prevalence and antigenic profile ofEchinococcus cysts (CE cysts) in camels and cattle. The lungs, livers, hearts, and kidneys of 560 animals, comprising 304 camels and 256 cattle slaughtered in the Maiduguri abattoir, were examined for CE. Blood samples were collected for serology. Protein profiles of CE fluids were analyzed using indirect Enzyme Linked Immunosorbent Assay while Sodium Dodecyl Sulphate Polyacrylamide Gel Electrophoresis (SDS-PAGE) was used to characterize the electrophoretic pattern of different CE cyst fluid samples. The overall prevalence of CE was 8.4%, 14.14% (...

Eimeria infections among commercial laying chickens in Nigeria: the prevalence and clinico-histopathological changes
This study was designed to determine the nation-wide prevalence and clinico-histopathological changes associated withEimeria infections in commercial laying birds in Nigeria. One Thousand eight hundred and forty-three (1843) commercial laying chickens from 28 states and the Federal Capital Territory (FCT) of Nigeria, between 2007 and 2016 were examined for the presence ofEimeria parasites and for clinicopathological lesions. Simple flotation and the McMaster techniques were used to confirm the presence ofEimeria oocysts and estimate the oocyst load.

Dactylogyrus kolodynensis sp. n. (Platyhelminthes: Monogenea) infecting gills of Osteobrama cotio (Hamilton, 1822) (Cypriniformes: Cyprinidae) from India
AbstractDactylogyrus kolodynensis, a new monogenean parasite species, is described fromOsteobrama cotio (Cyprinidae) collected from Lawngtlai (Mizoram) and Lucknow (Uttar Pradesh), India, using morphological examination and sequencing of partial 28S rRNA gene. The new species is morphologically characterized and distinguished from closely related congeners by a combination of the following characters: copulatory tube a loose coil of one complete clockwise ring, jaw-shaped accessory piece comprising variable sheathes enclosing and guiding the copulatory tube, and sclerotized vaginal tube, with a terminal flower-bud-shaped v...

An update on Cryptosporidium biology and therapeutic avenues
AbstractCryptosporidium species has been identified as an important pediatric diarrheal pathogen in resource-limited countries, particularly in very young children (0 –24 months). However, the only available drug (nitazoxanide) has limited efficacy and can only be prescribed in a medical setting to children older than one year. Many drug development projects have started to investigate new therapeutic avenues.Cryptosporidium’s unique biology is challenging for the traditional drug discovery pipeline and requires novel drug screening approaches. Notably, in recent years, new methods of oocyst generation, in vitro proce...

Prevalence and burden of gastrointestinal parasites in stray cattle of the Kathmandu Valley
This study was conducted to determine the prevalence of GIPs in stray cattle of the Kathmandu valley. One hundred (n = 100) freshly voided dung samples were collected from eight sites. The samples were processed using the concentration method for microscopic examination, and modified McMaster technique for quantification of mean eggs/oocysts per gram of feces (EPG/OPG). Results revealed that 72% of the cattle were found positive for one or more species of GIPs and nine genera of GIPs were recorded (Eimeria,Ostertagia,Haemonchus,Trichostrongylus,Capillaria,Trichuris,Toxocara,Fasciola andParamphistomum). The prevalence...

In vivo evaluation of anticryptosporidial effects of wheat germ extracts in immunocompromised mice
This study was done to evaluate the possible role of wheat germ extracts inCryptosporidium parvum (C. parvum) infected immunocompromised mice. Thirty white albino mice were classified into six groups as follow: four study groups, all immunosuppressed and infected withC. parvum oocysts. These four groups received treatments as follow:Group (I): treated with nitazoxanide.Group (II): treated with wheat germ oil.Group (III): treated with wheat germ extracted by hexane.Group (IV): treated with wheat germ extracted by ethanol. The remaining two groups were immunosuppressed control groups as follow:Group (V): only infected with C...

Occurrence of Eimeria species (Apicomplexa: Eimeriidae) in domestic rabbits (Oryctolagus cuniculus) in Qena Governorate, Upper Egypt
AbstractThe importance of rabbits for economic, medical, and biological purposes has been well appreciated. In the present study, a total of 200 domestic rabbits were collected from Qena Governorate, Egypt, from 2018 to October 2020. Their fecal samples were tested for the presence ofEimeria species oocysts using the standard flotation technique, which revealed oocysts in 100 rabbits (50%).

Gastrointestinal helminth parasites of wild ungulates in Hirpora Wildlife Sanctuary, Kashmir, India
AbstractParasitic infection represents an emerging threat to wild ungulates and a challenge to their management. Although a lot of work has been carried out on helminth parasitic infestation of domestic ungulates of Kashmir but the data pertaining to this aspect of wild ungulates has been ignored. The study on gastrointestinal helminth parasitic infestation of wild ungulates was carried out during post livestock grazing period (November to May) of 2018/2019 in Hirpora Wildlife sanctuary (HWLS) to fill the gap in the existing literature. During the study fresh faecal samples of musk deerMoschus spp. (n = 44) and markhor...

Canine hepatic calodiosis with cirrhosis
AbstractThe nematode parasiteCalodium hepaticum (Capillaria hepatica) has a global distribution and is commonly reported in rodents (definitive host), dogs, cats and wild animals. Humans especially children are more susceptible to the parasitic infection. This paper documents an incidental finding of hepatic calodiosis with cirrhosis in a stray dog and discusses the zoonotic implications. A non descript dog was brought for necropsy examination to the Department of Veterinary Pathology, Madras Veterinary College, Tamil Nadu, India. Liver appeared dark brown, mottled with multifocal random variably sized, grey white flat fir...

Molecular diagnosis of trypanosomatids in Didelphis marsupialis from Los Montes de Mar ía: a first report of Trypanosoma rangeli from Colombian Caribbean region
AbstractDidelphis marsupialis is a primary reservoir ofTrypanosoma cruzi, etiologic agent of American Trypanosomiasis-AT or Chagas Disease-CD, in America. Some findings ofTrypanosoma rangeli have been recorded in this mammal, in sympatry withT. cruzi. In Los Montes de Mar ía, Bolívar, Colombian Caribbean, triatomine insects and potential parasite host has been registered, but little is known about the relationship between these parasites andD. marsupialis. We investigated the natural trypanosomatids infection rate inD. marsupialis, applying a parasitological and molecular diagnosis. TwentyD. marsupialis was investigated ...
