Case of the Week 560

This week's case is a composite photo I created for my 2019 calendar for the month of September. The accompanying questions are:What is the parasite shown? (measure ~60 micrometers long)Why is this a suitable parasite for September?What is the significance of the other objects in the picture?

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.

Mitogen-activated protein kinases (MAPKs) play a regulatory role and influence various biological activities, such as cell proliferation, differentiation, and survival. Our group has demonstrated through functional studies that Schistosoma mansoni c-Jun N-terminal kinase (SmJNK) MAPK is involved in the parasite’s development, reproduction, and survival. SmJNK can, therefore, be considered a potential target for the development of new drugs. Considering the importance of SmJNK in S. mansoni maturation, we aimed at understanding of SmJNK regulated signaling pathways in the parasite, correlating expression data with S. ...

In cattle, clinical presentations and outcomes of bovine theileriosis are closely correlated with the causative Theileria spp. Thus, accurate detection and discrimination of Theileria spp. are essential for epidemiological studies and for provision of ...

Authors: Szuster-Ciesielska A, Wawiórka L, Krokowski D, Grankowski N, Jarosz Ł, Lisiecka U, Tchórzewski M Abstract Malaria remains one the most infectious and destructive protozoan diseases worldwide. Plasmodium falciparum, a protozoan parasite with a complex life cycle and high genetic variability responsible for the difficulties in vaccine development, is implicated in most malaria-related deaths. In the course of study, we prepared a set of antigens based on P-proteins from P. falciparum and determined their immunogenicity in an in vivo assay on a mouse model. The pentameric complex P0-(P1-P2)2 wa...

by Jiarong Gao, Ning Yang, Fred A. Lewis, Peter Yau, James J. Collins III, Jonathan V. Sweedler, Phillip A. Newmark Schistosomes are parasitic flatworms that infect over 200 million people, causing the neglected tropical disease, schistosomiasis. A single drug, praziquantel, is used to treat schistosome infection. Limitations in mass drug administration programs and the emergence of schistosomiasis in nontropic al areas indicate the need for new strategies to prevent infection. It has been known for several decades that rotifers colonizing the schistosome's snail intermediate host produce a water-soluble factor that paral...

In this study, dependency of antibody production in Leishmania infection on BAFF was examined by using BAFF-knockout (BAFF-KO) mice. When BAFF-KO mice were infected with L. major, there was no significant difference in lesion development or parasite burden from those in infected wildtype mice. In contrast, levels of IgG antibodies to Leishmania crude antigen were lower in BAFF-KO mice, suggesting that antibody production during L. major infection is BAFF-dependent. ELISA using defined leishmanial antigens demonstrated that the influence of BAFF on antibody production during L. major varies depending on antigens; IgG produc...

Publication date: Available online 15 October 2019Source: TrAC Trends in Analytical ChemistryAuthor(s): Sona Jain, Thyago Gois Costa Melo, Silvio Santana Dolabella, Juewen LiuAbstractWater-borne protozoan parasites like Cryptosporidium, Giardia, Entamoeba and Toxoplasma are responsible for 1.7 billion cases of diarrhea globally, representing the second most frequent reason for mortality among children under five. They show an environmentally resistant cyst/oocyst stage. Despite their importance, the standard analytical methods for their detection still rely on immunostaining followed by microscopic analysis. In recent year...

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...
