Opportunistic Coccidiosis in Brazil: Diagnostic Challenges and Epidemiological Gaps in Immunosuppressed Groups

Journal of Tropical Medicine, Volume 2026, Issue 1, 2026.
Opportunistic infections caused by the protozoa Cryptosporidium spp. and Cystoisospora belli represent a challenge for public health, particularly in immunocompromised patients. In Brazil, a country with continental dimensions and socioeconomic diversity, the epidemiology of these intestinal coccidioses is complex and often underestimated.

A longitudinal study of natural infection of piglets with Streptococcus suis types 1 and 2 [PDF]

, 1991
Streptococcus suis types 1 and 2 were detected in nasal swabs taken from five litters of piglets sampled twice weekly from birth. The two types had been detected in all pigs by the time they were 38 and 25 days old respectively with mean ages of first ...

Identification and characterization of two temperature-induced surface-associated proteins of Streptococcus suis with high homologies to members of the arginine deiminase system of Streptococcus pyogenes [PDF]

, 2002
The present study was performed to identify stress-induced putative virulence proteins of Streptococcus suis. For this, protein expression patterns of streptococci grown at 32, 37, and 42°C were compared by one- and two-dimensional gel electrophoresis ...

Zoonotic Parasites in Marmosets (Callithrix Spp.) From Southern Brazil: Insights From a One Health Perspective

Journal of Medical Primatology, Volume 54, Issue 5, October 2025.
ABSTRACT Background Currently, six species of Callithrix are frequently observed in anthropized and degraded environments in different regions of Brazil. This occupation favors interactions with humans and increases the risk of infection by parasites with zoonotic potential.

Aspects of Genetic Diversity, Host Specificity and Public Health Significance of Single‐Celled Intestinal Parasites Commonly Observed in Humans and Mostly Referred to as ‘Non‐Pathogenic’

APMIS, Volume 133, Issue 9, September 2025.
ABSTRACT Clinical microbiology involves the detection and differentiation of primarily bacteria, viruses, parasites and fungi in patients with infections. Billions of people may be colonised by one or more species of common luminal intestinal parasitic protists (CLIPPs) that are often detected in clinical microbiology laboratories; still, our knowledge

Image_1_Unravelling the sexual developmental biology of Cystoisospora suis, a model for comparative coccidian parasite studies.jpeg

, 2023
IntroductionThe apicomplexan parasite Cystoisospora suis has global significance as an enteropathogen of suckling piglets. Its intricate life cycle entails a transition from an asexual phase to sexual development, ultimately leading to the formation of ...

An evaluation of the correlation between haematological biomarkers in cats affected with periodontal disease stages 3 and 4

Veterinary Record Open, Volume 12, Issue 1, June 2025.
Abstract Background Periodontal disease is the most common disease of the tooth‐supporting apparatus in dogs and cats. Identifying factors associated with periodontal disease early through minimally invasive, fast and cost‐effective methods, such as a simple blood test, may improve treatment outcomes.

Fussing About Fission: Defining Variety Among Mainstream and Exotic Apicomplexan Cell Division Modes

Frontiers in Cellular and Infection Microbiology, 2020
Cellular reproduction defines life, yet our textbook-level understanding of cell division is limited to a small number of model organisms centered around humans.
