Trypanosoma vivax infection in goat in west of Santa Catarina state, Brazil

Abstract The aim of this study was to report the Trypanosoma vivax in goats from a property located in the west of the state of Santa Catarina, Brazil. The identification of the parasite occurred at random, that is, it was displayed a similar morphological trypomastigote form in the blood smear of an animal in the property. Subsequently, in blood samples collected from five goats on the same day, it was confirmed by polymerase chain reaction (PCR) the presence of the parasite in three of these animals. Being that by chance, consistent clinical signs related to trypanosomosis in these animals were not observed. The animals were not subjected to therapeutic treatment, because the molecular confirmation of the parasitism happened 1.4 years after the sample collection. Therefore, the T. vivax parasite infects goats in the state of Santa Catarina, Brazil.

Authors: Çulha G, Kaya T, Gülbol Duran G, Urhan Küçük M, Doğramacı AÇ, Tiyekli Çelik D Abstract Leishmaniasis is a parasitic disease that is transmitted to humans by the bites of infected female phlebotomine sandflies. In the diagnosis of cutaneous leishmaniasis (CL), in the smear samples, the demonstration of the parasite by microscope remains a gold standard method. However, it becomes difficult to diagnose the parasite since the number of amastigotes in chronic cases with a lesion of one year or longer is very low. Due to many factor such as patients primarily do not ...

Authors: Mosayebi M, Mohebali M, Farazi A, Shirzadi MR, Akhlaghi D, Hajhossein R, Elikaee S Abstract Cutaneous leishmaniasis (CL) is one of the prevalent parasitic diseases in Iran principally caused by two species, Leishmania major and L. tropica. Here, we present a rare case of a congenital form of CL around the glans penis from the central part of Iran in 2017. A 24-yr-old male patient from the central part of Iran presented with biennial ulceration of the glans penis. Diagnostic methods included physical and preclinical examination, microscopic observation, leishmanin skin test (LST), and serological tests incl...

Conclusion: All the patients with inflammatory eye diseases such as endophthalmitis, uveitis DCR, glaucoma and cataract were studied for Toxocara infection in this research work were at risk. Therefore, in contrast to the previous idea, all eye inflammatory diseases in ocular patients should be considered for Toxocara antibodies in addition to Uveitis. PMID: 31673264 [PubMed]

This study aimed to investigate the circulation of L. infantum among sylvatic hosts in Sicily (southern Italy), a highly endemic area for canine leishmaniosis, through serological and molecular tools. Target tissues (skin, spleen, lymph nodes) collected from 71 European rabbits, 2 European hares, 7 red foxes, 11 European wildcats and 1 pin. marten, were qPCR analysed for the detection of L. infantum DNA. Additionally, 40 rabbits, older than one year, were serologically screened for specific anti-Leishmania antibodies. Leishmania infantum was molecularly diagnosed in 5.4% (n = 5) of the examined animals...

This study was aimed to assess the eggs of gastrointestinal parasites of stray dogs and household dogs in lower Dir district, Pakistan with special consideration to those that can be spread to humans. One hundred and fifty two stool specimens from (stray dogs=90 and household dogs=62) were collected. The helminth eggs were processed by direct smear method and centrifugation techniques and identified by microscopic examination. Of the total examined dogs 26.8% (n=41 /152) were found to be infected with one or more intestinal parasites. The intestinal helminths detected were Dipylidium caninum (n =18, 11.8%), followed by Tox...

ConclusionsThe rate of helminthic co-infection is predominantly high than that of intestinal protozoa. Single parasitic co-infection was more common than double or multiple co-infections. Both body mass index and mid-upper arm circumference anthropometric parameters revealed greater risk of undernutrition in tuberculosis patients. Thus, screening and prompt treatment of parasites in tuberculosis patients and a support of nutritional supplementation for malnourished tuberculosis patients should be further studied which might enhance the disease treatment and minimize the risk of its complexity.

This study aimed to evaluate the efficacy of conventional smear cytology (SC), liquid-based cytology (LBC), cell block (CB) stained with haematoxylin and eosin (HE) and immunocytochemistry (ICC), and formalin-fixed paraffin wax-embedded tissue immunohistochemistry (FFPE–IHC) compared with serology and polymerase chain reaction for the diagnosis of canine visceral leishmaniosis (CVL) in lymphoid tissue. The use of a preservative medium and centrifugation for cytological samples reduced the number of unsatisfactory artefacts/background. Moreover, LBC allowed excellent cellular preservation and the application of ancill...
