Cryptosporidium spp. are opportunistic pathogens that cause diarrhea in a variety of animal hosts. Although they have been reported in many animals, no information has been published on the occurrence of Cryptosporidium spp. in red-bellied tree squirrels (Callosciurus erythraeus). A total of 287 fecal specimens were collected from Sichuan province in China; the prevalence of Cryptosporidium spp., measured by nested-PCR amplification of the partial small-subunit (SSU) rRNA gene, was 1.4% (4/287). Three different Cryptosporidium species or genotypes were identified: Cryptosporidium parvum (n = 1), Cryptosporidium wrairi (n = 1), and Cryptosporidium rat genotype II (n = 2). The present study is the first report of Cryptosporidium infection in red-bellied tree squirrels in China. Although there is a relatively low occurrence of Cryptosporidium, the presence of C. parvum and C. wrairi, which were previously reported in humans, indicates that red-bellied tree squirrels may be a source of zoonotic cryptosporidiosis in China.

AbstractIn this study we aimed to determine seroprevalence of antibodies against Toxoplasma gondii and parasite DNA presence in the milk of goats from a farm in eastern Slovakia. Anti-Toxoplasma antibodies were detected in 43 goat sera out of 87 examined (49.43%). The highest prevalence was recorded in the goats aged more than 72 months (76.19%; OR = 4.62; 95% CI = 1.51-14.14) and the lowest one in animals aged from 12 to 36 months (17.65%; OR = 0.09; 95% CI = 0.03-0.27). Statistically significant correlation (P < 0.0001) was found between the prevalence of antibodies against T. gondi and animal age in comparing age groups - goats up to 36 months of age and above 37 months of age. The presence of T. gondii DNA was confirmed in 32.56% of milk samples using molecular methods. Based on the DNA polymorphism at the SAG2 locus of T. gondii we identified the goats as being infected with genotype II of T. gondii. Presence of DNA in milk refers to the risk of human infection through consuming raw milk.

Abstract Some neurotropic enteroviruses hijack Trojan horse/raft commensal gut bacteria to render devastating biomimicking cryptic attacks on human/animal hosts. Such virus-microbe interactions manipulate hosts’ gut-brain axes with accompanying infection-cycle-optimizing central nervous system (CNS) disturbances, including severe neurodevelopmental, neuromotor, and neuropsychiatric conditions. Co-opted bacteria thus indirectly influence host health, development, behavior, and mind as possible “fair-weather-friend” symbionts, switching from commensal to context-dependent pathogen-like strategies benefiting gut-bacteria fitness.
