A total of 413 pig faecal samples were collected from pre-weaners (119), starters (131), pre-growers (123) and sows (40) from a farm with a closed breeding system segmented into two breeding complexes and a growing complex in the region of Vysocina, Czech Republic and screened for the presence of Cryptosporidium using staining methods and genotyping (SSU rRNA). Cryptosporidium oocysts were detected by microscopy in the faeces of 21.1% of the samples (87/413). Sequence analyses and RFLP identified C. suis in 44, Cryptosporidium pig genotype II in 23 and C. muris in 2 samples. No mixed infections were found. Pigs under 7 weeks of age were infected with C. suis only. Cryptosporidium pig genotype II was found in animals from 7 weeks of age. No relationship was found between diarrhoea and any Cryptosporidium infection in any of the different age groups (P<0.05). The pre-weaned pigs shed significantly more Cryptosporidium oocysts than older pigs and it was associated with C. suis infection.

Introduction: Increasing urbanization has particularly affected rivers and their outer edges in cities, including Kathmandu Valley, which encompasses Lalitpur, the nation's third-largest city. This study aims to conduct a parasitological survey to investigate the occurrence of zoonotic intestinal protozoa and helminths along the Karmanasa River bank in central Nepal.
Methods: Faecal samples from openly defaecating animals were collected via non-invasive techniques, and coproscopy was carried out using direct wet mount, concentration and acid-fast staining methods to ensure reliable findings.

Clustered regularly interspaced short palindromic repeats (CRISPR)-CRISPR-associated protein (Cas) technology has revolutionized genome editing across various biological systems, including the Apicomplexa phylum. This review describes the status, challenges, and applications of CRISPR-Cas9 editing technology in apicomplexan parasites, such as , , , , and . The discussion encompasses successfully implemented CRISPR-Cas9-based techniques in these parasites, highlighting the achieved milestones, from precise gene modifications to genome-wide screening.

and G are recognized as significant etiological agents of diarrheal outbreaks in humans as these parasites may be transmitted through the ingestion of water and food contaminated with feces of human or animal origin. However, surveillance studies on the role of animal reservoirs in the transmission of and are deemed insufficient and the complete dimension of the problem contributing to contamination in an agricultural setting is unknown. This study aimed to assess the presence of and in domesticated animals from selected farms in the agricultural provinces of Laguna and Quezon in Southern Luzon, Philippines.

As an alternative to traditional serological markers, that is, antibodies, for serum-based specific diagnosis of infections, circulating non-antibody markers may be used to monitor active disease. Acute phase proteins (APPs) are a prominent class of such markers widely used for diagnosing ongoing inflammation and infection. In this chapter, basic theoretical and practical considerations on developing APP assays and using APPs as markers of ongoing infection are presented with a specific focus on intracellular infections in pigs.
