Summary: Cryptosporidium, a parasitic organism, is a significant cause of diarrheal disease in humans and animals globally. There is a high prevalence of cryptosporidiosis in both humans and animals in Iraq, with reports indicating confusing results and a need for further epidemiological and molecular studies to accurately assess the situation.

Summary: The Keap1-Nrf2 system regulates the cellular response against oxidative and xenobiotic stresses. In cancer cells, hyperactivation of Nrf2 leads to metabolic reprogramming and increased resistance against cancer therapies. This study shows that encapsulating Halofuginone (HF) in polymeric micelles can reduce systemic toxicity while maintaining the tumor-suppressive properties of HF.

Summary: The study showed a significantly higher infection rate of Cryptosporidium parvum during the outbreak, particularly associated with watery diarrhea in neonatal calves at a large cattle farm in Hebei Province, China. The subtype identified in the C. parvum isolates was IIdA20G1, highlighting the importance of monitoring and controlling the spread of this pathogen in China.

Summary: This study aimed to investigate the effect of feeding milk fermented with a combination of four probiotic bacterial strains on reducing the occurrence of calf-diarrhoea. The results showed that this feeding approach did not significantly reduce the prevalence of diarrhoea but had a detrimental effect on daily-weight-gain.

Summary: In this study, it was shown for the first time that neonate bovine PMN are capable of forming NETs against C. parvum-sporozoites and oocysts, regardless of their stage. The research also found that C. parvum strongly induces suicidal neonatal NETosis in a P2X1-dependent manner, suggesting its anti-cryptosporidial effects through various mechanisms.

Summary: The study revealed a high prevalence of C. parvum infection in calves, which was associated with environmental contamination and clinical signs of diarrhea, while the provision of a yard in the delivery enclosure may reduce the risk of infection. Management of the delivery enclosure appears crucial in preventing cryptosporidiosis in calves in Taiwan.

Summary: Severe diarrhea occurred in goat kids in Chungcheongbuk-do, Korea from 2021 to 2023, and Cryptosporidium infection was suspected. Fecal samples were collected from goat farms experiencing diarrhea and analyzed for Cryptosporidium infection. Cryptosporidium was identified in 53.8% of the samples, with a higher prevalence in diarrheic fecal samples from young goats. Phylogenetic analysis revealed two Cryptosporidium species, including C. parvum and C. xiaoi, with the presence of zoonotic subtypes. This study highlights the importance of goat kids as reservoir hosts for different Cryptosporidium species and emphasizes the need for continuous monitoring and biosecurity measures to control cryptosporidiosis outbreaks.

Summary: Gastrointestinal disease is the most common illness in pre-weaned dairy calves. This study found that the composition of the fecal microbiome is associated with clinical symptoms of GI disease, as well as the severity and breed specificities of the disease.

Summary: Neonatal calf diarrhea (NCD) is often caused by various viral, bacterial, and protozoal infections. Current diagnostic methods require specific tests for each potential pathogen, which is time-consuming and expensive. In this study, we developed a multiplex PCR/RT-PCR assay for simultaneous detection of five major NCD agents, providing a faster and easier diagnostic tool for routine use.

Summary: L. reuteri is important for the intestinal health of newborn calves, and oral administration of preselected L. reuteri isolates can significantly reduce the incidence of diarrhea in newborn calves. This study provides evidence supporting the use of L. reuteri as a potential protective measure against diarrhea in dairy farms.

Summary: The death and disease rate in young dairy calves, mainly caused by diarrhea, is high. The current treatment with antimicrobials may not be necessary and could lead to antimicrobial resistance. Bovine colostrum, packed with essential nutrients and bioactive factors, shows potential as an alternative therapy for diarrhea in young calves.

Summary: This study demonstrated the promising prophylactic and therapeutic effects of clinoptilolite against Cryptosporidium parvum infection in experimentally infected lambs. It significantly reduced oocyst counts, improved fecal consistency, and enhanced clinical health scores. The efficacy was calculated to be 97.4% in the prophylactic group and 91.6% in the therapeutic group.

Summary: The study utilized metagenomic analysis to investigate the dynamic changes in the fecal microbiome of pre-weaned dairy calves, revealing significant shifts in gut microbiome composition during diarrheal disease and increased diversity with age. The findings suggest important implications of gut microbiota in the metabolism and health status of neonatal dairy calves.

Summary: Cryptosporidium parvum is a parasite causing cryptosporidiosis responsible for about one million human deaths, impacting host cell metabolism and relying on glycolysis and glutaminolysis pathways. Targeting these metabolic pathways could lead to new anti-infection targets.

Summary: Capybaras are affected by a wide range of parasitic diseases, including potential zoonotic parasites. A study in the Orinoco Basin identified various gastrointestinal parasite infections in capybara populations, with two zoonotic parasites found. This research provides valuable baseline data for monitoring wildlife-derived anthropozoonotic parasites and highlights the need for further research on the health and ecological impact of capybaras.

Summary: This study aimed to characterize gastrointestinal parasites of four out of six Neotropical wild felid species endemic to Colombia. The results demonstrate the potential role of these felids as natural reservoir hosts for neglected zoonotic parasites and highlight their possible role in parasite transmission to human communities. Monitoring the occurrence of these parasites in the future is crucial for appropriate zoonotic management practices in conservation strategies and wild felid health management programs.

Summary: This study aimed to address the lack of in vitro studies on Cryptosporidium parvum in the most important animal host under physiological oxygen conditions. The metabolic analyses of infected bovine small intestinal explants revealed dynamic changes in metabolic activities, and highlighted the influence of physiological oxygen concentrations on these responses. The ex vivo model developed in this study provides insights into the metabolic modulation of intestinal cells by C. parvum, and offers a realistic platform to study the interactions between the parasite, host cells, and intestinal microbiome.
