Summary: The diagnosis of eimeriosis in calves relies on the presence of diarrhoea and Eimeria oocysts in the faeces. This study introduced a method for quantifying oocysts in environmental barn straw samples and obtained a recovery rate of 52.4%. Results showed that Eimeria oocysts were present in faecal and straw samples from all farms, and the oocyst numbers in straw correlated positively with those in faeces. The examination of environmental straw samples could serve as an easy, non-invasive, and inexpensive preliminary diagnostic approach for eimeriosis surveillance at group level.

Summary: This study evaluated the effects of Eimeria mitis on Eimeria necatrix or Eimeria tenella infection and found that the presence of E. mitis exacerbated the outcome of co-infection with E. tenella. However, it had little impact on the infection outcome of E. necatrix. These results suggest the importance of considering the relationships among different Eimeria species when using mixed infection models.

Summary: The study aimed to establish a practical method for the isolation of psychrophilic and psychrotolerant Clostridium spp. by heating meat drip samples enriched in PYGS broth and successfully isolating strains by inactivating other microbiota through heat treatment.

Summary: Coccidiosis, a major intestinal disease in the chicken production industry, is caused by various Eimeria species. This study successfully detected and identified the Eimeria species in local chicken farms using microscopic observation and PCR. The established and purified Eimeria populations will be valuable for the development of more effective control methods.

Summary: A method combining morphology and molecular biology was established to accurately identify Eimeria species in domestic rabbits. The total infection rate of Eimeria in domestic rabbits was found to be 44.2%, with 10 different species identified.

Summary: Over 100 wild turkey fecal samples were collected from non-commercial turkey production areas in the United States between 2018 and 2020. The presence of anticoccidial-sensitive Eimeria spp. in the samples was confirmed, and their sensitivity to specific anticoccidial drugs was tested.

Summary: A mixed Eimeria spp. challenge model was designed to evaluate the effects of challenge on broiler chicken performance, intestinal integrity, and microbiome. The experimental design involved two groups: a control group and a positive control group infected with Eimeria acervulina, Eimeria maxima, and Eimeria tenella. The results showed reduced body weight gain and feed conversion ratio in the infected group, higher intestinal lesion scores, increased intestinal permeability, altered gene expression, and changes in the gut microbiome composition. This model can be used to assess alternative strategies for controlling coccidiosis in broiler chickens.

Summary: Immunization with attenuated Eimeria spp. oocysts can reduce the shedding of oocysts and the severity of clinical coccidiosis in goats, but the degree of immunoprotection is lower against mixed Eimeria spp. infections.

Summary: The aqueous Sacoglottis gabonensis stem bark extract (SGSBE) was evaluated for its anti-coccidial effects and toxicity in broiler chickens. The results showed that SGSBE significantly reduced oocyst output, clinical signs, and lesions, while improving body weight, survivability, and haemato-biochemical indices in the treated groups.

Summary: This review discusses the advantages and disadvantages of molecular methods used for the identification of Candida species, with a special focus on oral candidiasis. It explores the application of these methods for the diagnosis of oral infections, aiming to find the most rapid, affordable, accurate, and easy-to-perform molecular techniques as point-of-care testing methods.

Summary: This study presents an easy method for isolating Pichia species from grape must and investigates their co-fermentation effects with Saccharomyces cerevisiae on wine characteristics. The results show that co-inoculation with different Pichia species leads to changes in specific compound levels and increased glycerol content in the wine.
