“…In contrast, an English study found no human exposure to N. caninum antigens at all, despite a large study population, which consisted of 3,232 serum samples from the general population and 518 serum samples from a high-risk group (farm workers) (387). However, a recent study from Egypt found a Neospora seroprevalence of 7.92% in human serum samples (288). In a study from France, no sera from ICT women were positive for anti-N. caninum antibodies, although 4/400 serum samples from HIV-infected patients tested positive for anti-N. caninum antibodies (478).…”

Importance of Nonenteric Protozoan Infections in Immunocompromised People

SUMMARY There are many neglected nonenteric protozoa able to cause serious morbidity and mortality in humans, particularly in the developing world. Diseases caused by certain protozoa are often more severe in the presence of HIV. While information regarding neglected tropical diseases caused by trypanosomatids and Plasmodium is abundant, these protozoa are often not a first consideration in Western countries where they are not endemic. As such, diagnostics may not be available in these regions. Due to global travel and immigration, this has become an increasing problem. Inversely, in certain parts of the world (particularly sub-Saharan Africa), the HIV problem is so severe that diseases like microsporidiosis and toxoplasmosis are common. In Western countries, due to the availability of highly active antiretroviral therapy (HAART), these diseases are infrequently encountered. While free-living amoebae are rarely encountered in a clinical setting, when infections do occur, they are often fatal. Rapid diagnosis and treatment are essential to the survival of patients infected with these organisms. This paper reviews information on the diagnosis and treatment of nonenteric protozoal diseases in immunocompromised people, with a focus on patients infected with HIV. The nonenteric microsporidia, some trypanosomatids, Toxoplasma spp., Neospora spp., some free-living amoebae, Plasmodium spp., and Babesia spp. are discussed.

“…Correlation between weather parameters and prevalence of acute infection in cattle and buffaloes in northern Punjab, Pakistan seroprevalence reported in southwestern parts of Pakistan [17], 22.3% in Thailand [10], 93.5% in Turkey [18], and 71.3% in Iran [19]. Comparatively, lower seroprevalence rates of 4.8%, 10.75%, 2.60%, 3.86%, and 5.70% have been found in Iran [20], Egypt [21], Malaysia [22], Korea [23], and China [24], respectively. Varying rates of seroprevalence in buffaloes have also been reported by various researchers in several countries, including 20.4% in Afghanistan [25], 3% in Vietnam [26], 8.8% in Iran [12], 30% in Iraq [11], 2.9% in India [27], and 7.8% in Trinidad [13].…”

Introduction: Toxoplasmosis is a widespread zoonosis that causes significant economic losses due to abortions and other developmental disabilities in livestock animals. The objectives of the current study were to determine the prevalence and associated risk factors of Toxoplasma gondii infection in cattle and buffaloes in northern parts of Punjab, Pakistan, where no such work previously existed. Methodology:Serum samples obtained from 400 cattle and 422 buffaloes present on different private and government-owned farms were tested for anti-Toxoplasma IgG and anti-Toxoplasma IgM antibodies by using enzyme linked immunosorbent assay (ELISA). Additional data, including water sources, hygienic status at the farm, management practices, size of the herd, and presence of cats in the vicinity of the farm were obtained using a questionnaire in surveys and interviews. Results: The overall prevalence of infection was 19.75% (79/400) in cattle and 15.16% (64/422) in buffaloes. IgG antibodies were found in 75 (18.75%) cattle and 58 (13.74%) buffaloes, while IgM antibodies were found in 9 (2.25%) cattle and 10 (2.37%) buffaloes. Seroprevalence was significantly higher in females and older animals of both species. Seroprevalence was found to be associated with poor hygienic conditions, extensive management practices, and presence of cats in the surrounding areas. No difference of seroprevalence was observed with respect to different breeds, location, water source, and herd size. Conclusion: The present study found that T. gondii is prevalent in large ruminants in northern Punjab, and may have important implications for the livestock industry and public health.
