Amoebas are characterized by their unique ability to exist both as free-living organisms and, occasionally, as parasites within host tissues, earning them the designation 'amphizoic amoebae'. While amoebic infections are less prevalent, their health impact can be tremendous, leading to several diseases. In low-income countries, poor sanitation and socioeconomic conditions significantly increase the risk of amoebic infections, particularly E.

With the increasingly close coexistence between pets and humans, coupled with reports of Cryptosporidium cross-infection between felines and their guardians, research aimed at understanding the epidemiology of these parasites in specific regions has become necessary. The principal objective of this study was to undertake a molecular characterization of Cryptosporidium in fecal samples from felines in the state of Goiás, Brazil (which is unprecedented for the region), and to assess the risk factors involved in the infection of these animals in the aforementioned locale. A total of 95 fecal samples were collected from domestic felines in the municipality of Goiânia, Goiás, Brazil.

Bioptic Laboratory, Ltd, Pilsen, Czech Republic.
Syphilis, known as "the great mimicker," is caused by the spirochete Treponema pallidum and is characterized by a diverse array of clinical and histopathologic presentations. In secondary cutaneous syphilis, the most consistent morphological features include a superficial and deep perivascular infiltrate containing plasma cells, varying degrees of endothelial swelling, irregular acanthosis, elongation of rete ridges, a vacuolated pattern, and the presence of plasma cells. Although serologic tests are essential for definitive diagnosis, spirochetes can sometimes be directly identified in silver-stained tissue slides or through immunohistochemistry.

Objectives: Arboviruses pose significant public health threats worldwide, with Southeast Asia being a hotspot for these infections. This study aimed to reassess the incidence of dengue, Zika, and chikungunya viruses in patients clinically diagnosed with dengue in East Java, Indonesia in 2023.
Methods: The study included 108 patients admitted to hospitals in Jember, with blood samples collected on admission.
Multiplex-PCR technique to predict polymorphic antigens - M, N, S and s - and associations between their alleles and Mi-associated hybrid glycophorins.

Serological typing of MNS polymorphic antigens - M, N, S and s - remains a fundamental technique in transfusion medicine and prenatal care, providing essential information for matching blood donors and recipients and managing haemolytic disease. Although this method is well proven and routinely used, it is not a comprehensive solution, as it has several weaknesses. Alternatively, multiplex polymerase chain reaction (PCR) is a commonly used genotyping tool due to its potency and ability to amplify several DNA targets simultaneously in a single reaction.
