Summary: A cross-sectional study conducted in Egypt found that the seroprevalence of Toxoplasma gondii in dromedary camels was 46.9%. Risk factors for T. gondii infection in camels included locality, sex, age, contact with small ruminants, history of abortion, and number of parities. Evaluating the seroprevalence and related risk factors is crucial for controlling T. gondii infection in camels and preventing transmission to humans.

Summary: This study investigated the seroprevalence and risk factors of T. gondii infection in cats across China. The study found higher infection rates in Sichuan, Chongqing, and Hunan, and reported the seroprevalence in Qinghai, Anhui, Jiangxi, Shaanxi, and Ningxia for the first time. Age and lifestyle (stray or pet) of cats were identified as risk factors for T. gondii infection.

Summary: The prevalence of seropositivity for Toxoplasma gondii varies in different subpopulations of cats in Greece, and is associated with age, history of cat-fight trauma, and lack of vaccination. This indicates that toxoplasmosis is still a significant public health concern in Greece, and optimal strategies for preventing T. gondii infection in cats should be established.

Summary: This study evaluated the seroprevalence and risk factors for Neospora caninum and Toxoplasma gondii in naturally exposed cattle in Portugal. The results showed a low but widespread seroprevalence of T. gondii, while N. caninum had a seroprevalence similar to other Mediterranean countries. Climate factors and management practices were significant predictors of infection for both parasites. The study highlights the importance of considering neosporosis in the differential diagnosis of cattle reproductive disorders and informing source attribution models for human toxoplasmosis.

Summary: The study showed a high seroprevalence of Toxoplasma gondii infection in giant pandas, with age and transfer history between institutions identified as main risk factors. It is suggested that age is a major factor, and housing multiple species in the same environment may increase the chance of cross-infection.

Summary: This study investigated the prevalence and risk factors of Toxoplasma gondii infection among high-risk populations in Jiangsu Province, eastern China. The results showed significantly lower infection rates in pregnant women and higher infection rates in cancer patients. Higher educational levels were associated with lower seropositivity rates for T. gondii infection.

Summary: The study revealed a high seroprevalence of T. gondii infection among women of childbearing age in Osun State, Nigeria, with rural residents and women of Islam religion showing higher susceptibility. Health education on toxoplasmosis and its transmission should be provided during prenatal follow-up to reduce the risk of infection in pregnant women.

Summary: This study aimed to investigate the seroprevalence of Toxoplasma infection in sheep in Blida, Bouira, and Medea regions in Algeria. The overall seroprevalence was 35.9%, with a herd seroprevalence of 77.3%. Medea had the highest prevalence (45.7%), followed by Blida (27.7%) and Bouira (14.3%). Logistic regression analysis revealed that semi-extensive sheep breeding, strong presence of cats, and highlands were associated with a higher likelihood of T. gondii infection.

Summary: This study aimed to investigate the seropositivity and associated risk factors of Toxoplasma gondii infection in pregnant women in Somalia. Blood samples from 403 pregnant women attending antenatal care at Benadir hospital were collected and analyzed, and the results showed an IgG seropositivity rate of 45.2% for T. gondii. The infection rate varied among different stages of pregnancy, with rates of 44.2%, 26.3%, and 67.7% in the first, second, and third trimesters, respectively. The findings suggest the need to integrate routine serological screening with other antenatal care services to identify potential T. gondii infections.

Summary: The study in Cuba's largest pork-producing region found that sows and locations below 250 meters above sea level are more likely to be seropositive for Toxoplasma gondii. This poses a public health concern as consumption of raw or undercooked pork meat products containing tissue cysts is a major route of T. gondii transmission worldwide.

Summary: This study found that 24% of sheep and 38.28% of goats in three governorates in Egypt were infected with Toxoplasma gondii, and age, sex, contact with cats, and hygienic conditions were identified as risk factors for the infection. The identification of risk variables can help take measures to reduce and prevent T. gondii infection in small ruminant animals and, consequently, human infection.

Summary: This study investigated the presence of coronaviruses in multiple bat species in Nigeria. It found a high diversity of coronaviruses in bats, with different bat species carrying viruses from the same genetic lineage. The results suggest that host switching may have contributed to the evolution of coronaviruses. Robust surveillance is recommended to enhance our knowledge of emerging and re-emerging coronaviruses.

Summary: Buruli ulcer is a neglected tropical disease mainly found in West and Central Africa. The mode of transmission is unknown and early diagnosis and treatment are crucial for reducing morbidity and preventing long-term disability. The gold standard for diagnosis is biological confirmation using PCR on cutaneous samples. In order to improve the diagnostic rate, 11 laboratories have created the network BU-LABNET to harmonize procedures and ensure quality control.

Summary: This study aimed to investigate the diversity of MTBC in Nigeria using the WGS approach. The most represented lineages were L4, followed by L1, L2, and L5, indicating a diversified MTB population. Additionally, the study found a lack of good genetic markers for drug resistance among the MTBC isolates in Nigeria, which may pose challenges for local tuberculosis management efforts.

Summary: This study examined the morphology of Schistosoma eggs recovered from human urine samples in four schistosomiasis endemic communities along the Oyan River Dam in Nigeria. Two major morphotypes of eggs were identified, suggesting possible hybridization between different Schistosoma species. Further molecular studies are needed to determine the genetic information of eggs and confirm the presence of Schistosoma bovis infection in cattle and vector snails in the hybridization areas.
