The efficiency of a modified flotation method for the isolation of Penicillium marneffei from soils has been evaluated. About 80% was recovered from sterilized soil freshly seeded with P. marneffei (100 conidia/1.5 g soil). When seeded non-sterile soil was used (at least 100 seeded conidia/1.5 g soil), P. marneffei could be effectively recovered by employing a combination of the flotation method and the mouse inoculation method.

The accumulation of phosphogypsum (PG) in the phosphorus chemical industry poses significant environmental challenges. Therefore, developing a harmless utilization method is crucial for alleviating these burdens and promoting sustainable industry practices. In this study, PG was used as a flotation inhibitor, enabling the flotation separation of apatite and dolomite based on the main components and dissolution behavior of PG.

Helminthiasis is a common infection in both humans and other animal populations and negatively affects the health of the host, causing a range of morbidity and even mortality, especially in young people and those with weakened immune systems. A variety of diagnostic procedures with a number of modifications are available to identify the sources of infection and to assess the epidemiological situation, the effectiveness of parasite control programs, anthelmintic treatment, and the prevention of drug resistance. These can be simple and cheap methods - for example, stool smear examination - or modern highly sensitive methods - for example, PCR analysis.

Background And Aim: The global prevalence of gastrointestinal (GI) and blood parasite infections in horses is a significant concern due to their substantial impact on morbidity, mortality, and economic losses in the horse industry. In Thailand, limited research has been conducted on these parasites in horse populations, and data from southern Thailand are lacking. Consequently, this study aimed to estimate the prevalence of GI and blood parasites in horses in Nakhon Si Thammarat province, Thailand.

Balantioides coli is the only ciliated protist of both human and veterinary interest and colonises the large intestine of several hosts, including humans and pigs. Given the scarcity of data on B. coli circulation in pigs in Italy, a study was planned to record its prevalence and genetic types and compare the analytical sensitivity of two copromicroscopic techniques.
