 Background: Toxoplasmosis is a disease associated with the nature of the population, domestic quality and general health culture. Toxoplasma gondii causes many healthy and psychological problems with the possibility of transmission from the mother to her fetus. The primary objective of this study is to establish a database of infection rates among the governorate's children, with the absence of a database of the parasite prevalence rate among children. Materials and method: Four hundred sixty-three serum samples from children 13 old and under  were collected during the period from 6 Jan. 2019 to 12 Dec. 2019, all of which were examined by ELISA test to detect immunoglobulin IgM and IgG. All results were analyzed by SPSS 20.  Results: The current study referred to high prevalence rates of T. gondii (23.3%), where the ratios of IgM and IgG were (4.1% and 17.9%) respectively. Compared with the present rates of immunoglobulin with gender, age, environment and animal contact. Conclusion:  Our current study registered high prevalence rates among children in Al-Qadisiyah governorate, this result represents a database of researchers and workers of health. It's the first study concerning the prevalence of toxoplasmosis in children in Al-Qadisiyah Province.

AbstractA cross-sectional study was carried out to determine the seroprevalence of Toxoplasma gondii and associated risk factors in pigs in the largest pork-producing region in Cuba. Serum samples from 420 pigs, including 210 sows and 210 post-weaning pigs, were tested for antibodies against T. gondii using a commercial indirect enzyme-linked immunosorbent assay. Anti-T. gondii antibodies were detected in 56 animals (13.3%, 95% CI: 10.1–16.6). A generalized estimating equations model revealed that the risk factors associated with higher seropositivity in pigs were altitude (higher in farm’s location < 250 m above sea level (masl) versus ≥ 250 masl) and age (higher in sows compared to post-weaning pigs). The results indicated that this protozoan parasite is widely distributed on pig farms in the study area, which is a public health concern since the consumption of raw or undercooked pork meat products containing tissue cysts is considered one of the main routes of T. gondii transmission worldwide. Control measures should be implemented to reduce the risk of exposure to T. gondii in pigs in Cuba.

This study was conducted to characterize the epidemiology of bovine brucellosis in the state of Pernambuco, Brazil. The state was divided into three regions, and in each region, approximately 300 properties were randomly sampled. From these selected properties, a pre-established number of animals were randomly selected and blood serum samples were obtained. A total of 3,901 animals were selected from 900 properties. For each selected property, an epidemiological questionnaire was administered to assess the type of farming, the animal husbandry practices and the sanitary practices that could be associated with the presence of brucellosis infection. The testing protocol consisted of screening the samples with a buffered acidified plate antigen test and retesting the positive samples with a complement fixation test (CF). One positive animal was enough to define an infected herd. The prevalence rates of infected herds and animals in the state were 4.5% [3.2; 6.4%] and 1.4% [0.7; 2.7%], respectively. By region, the prevalence rates of infected herds and animals, respectively, were as follows: Zona da Mata, 3.3% [1.8; 6.1%] and 1.7% [0.5; 3.0%]; Agreste, 7.4% [4.9; 10.9%] and 1.9% [0.8; 3.0%]; and Sertão, 1.3% [0.5; 3.5%] and 0.7% [0.0; 1.6%]. Flooded pastures (OR = 2.86 [1.37; 6.42]) and the presence of 13 or more females in the herd (3rd quartile) (OR = 2.65 [1.19; 5.89]) were identified as risk factors. The existence of veterinary care emerged as a protective factor against bovine brucellosis in the state of Pernambuco (OR = 0.24 [0.10; 0.58]).

Rabbits (Oryctolagus cuniculus) are frequently reared for meat production in China. The aim of this study was to assess the seroprevalence of Toxoplasma gondii and Encephalitozoon cuniculi, and risk factors of infection in domestic rabbits raised in Henan province, central China. 1,213 serum samples of domestic rabbits were collected and tested for anti-T. gondii and anti-E. cuniculi antibodies using a modified agglutination test (MAT) and an enzyme-linked immunosorbent assay (ELISA), respectively. The serum positive rates of T. gondii and E. cuniculi were 128/1,213 (10.55%) and 235/1,213 (19.37%), respectively. Co-infection of T. gondii and E. cuniculi was demonstrated in 84 specimens; 44 rabbits were seropositive for T. gondii alone, while 151 rabbits were seropositive for E. cuniculi alone. The main risk factors simultaneously associated with T. gondii and E. cuniculi infection were the age of the rabbit, the type of food, and the rabbit rearing system. Serum positive rates of T. gondii and E. cuniculi among domestic rabbits were high, indicating the possibility of public health issues.

AbstractToxoplasmosis is a parasitic zoonotic disease caused by Toxoplasma (T.) gondii. Limited data are available on the occurrence of T. gondii in women especially pregnant women in Pakistan. The present study aimed to determine the occurrence and risk factors associated with T. gondii in pregnant and non-pregnant women in Punjab Province, Pakistan. A cross-sectional study was conducted and 593 samples were collected from pregnant (n = 293) and non-pregnant (n = 300) women of District Headquarter Hospitals of Chiniot, Faisalabad, Jhang and Okara, Pakistan. Data related to demographic parameters and risk factors were collected using a pretested questionnaire on blood sampling day. Serum samples were screened for antibodies (IgG) against T. gondii using ELISA. A univariant and binomial logistic regression was applied to estimate the association between seropositive and explanatory variables considering the 95% confidence interval. P value ⩽0.05 was considered statistically significant for all analysis. Out of 593, 44 (7.42%) women were seropositive for T. gondii IgG antibodies. Occupation, age, sampling location, socioeconomic status, contact with cat, pregnancy status and trimester of pregnancy were significantly associated with seropositivity for T. gondii antibodies. Location and trimester of pregnancy were identified as potential risk factors for T. gondii seropositivity based on binomial logistic regression. Toxoplasma gondii is prevalent in pregnant and non-pregnant women. Therefore, now a necessitated awareness is required to instruct the individuals about these infectious diseases (toxoplasmosis) and their control strategies to maintain the health of human population. Moreover, health awareness among public can help the minimization of T. gondii infection during pregnancy and subsequent risk of congenital toxoplasmosis.

Coccidian Parasites

Toxoplasma gondii and Neospora spp. are closely related cyst-forming coccidian parasites, which infect various animal species and have considerable zoonotic and economic implications, respectively. Both parasites are endemic in Israel and have been reported to infect wild and domestic animals. This study was conceived to evaluate the serologic exposure of donkeys to these parasites. Serum samples were collected from 98 donkeys. Half of them (n = 49) were from animal shelters in Israel, and the rest (n = 49) were working donkeys from the Palestinian Authority. The donkeys were screened for the presence of anti-Toxoplasma and anti-Neospora antibodies by immunofluorescence antibody tests (IFATs). The seroprevalence of T. gondii and Neospora spp. was 94% and 70%, respectively, and 69% of the donkeys were exposed to both parasites. In addition, N. caninum tissue cysts were documented in two donkeys during post-mortem examination. This is the first report of the exposure of donkeys to T. gondii and Neospora spp. in the area. The high prevalence found in this study suggests that donkeys may have a role in the maintenance of these parasites in the area, thus serving as a source of infection for the definitive hosts.

Toxoplasmosis is a parasitic zoonosis with worldwide distribution and different wild species either are involved in maintenance of the pathogen in the environment as definitive or intermediate hosts serving as font of feeding or prey to definitive hosts. The present study aimed to investigate Toxoplasma gondii antibodies and the risk factors relating to infection in mammals at Sorocaba Zoo, state of São Paulo, Brazil. Serum samples collected from 153 animals were analyzed using the modified agglutination test (MAT; cutoff ? 25). Seropositivity was found in 62 animals (40.5%; 95% CI: 33.1-48.5%), with different titers. Significant differences were observed in relation to the ages of the animals, origin, presence of free-ranging animals in the enclosure and feeding habits, through univariate analysis (p ? 0.05). Multivariate logistic regression analysis showed that only age (p = 0.03) had significance for the study. Adult animals were 3.5 more likely to become infected than were young ones. In relation to feeding habits, herbivores (80%) and carnivores (46.5%) were the animals most affected. These results highlight the presence of T. gondii in animals at Brazilian zoos, and suggest that continuous transmission is occurring at zoos.

Toxoplasma Gondii Infection

AbstractPrevalence of antibodies to Toxoplasma gondii and risk factors with infection were assessed in dairy cattle from Gansu Province and Ningxia Hui Autonomous Region (NXHAR), northwest China. In total, 1657 serum samples were collected and assayed by the modified agglutination test. The overall seroprevalence was 4.83% at a 1:100 cut-off, with titers of 1:100 in 72, 1:200 in 4, 1:400 in 4. Among the risk factors examined, no statistically significant difference was observed between T. gondii seroprevalence and regions or age of dairy cattle in the logistic regression analysis (P>0.05) and left out of the final model. However, numbers of pregnancies of dairy cattle was considered as main risk factor associated with T. gondii infection. Dairy cattle in nulliparity group (8.89%) had 6 times (OR=6.31, 95% CI, 2.69-14.83, P<0.001) higher risk of being seropositive compared to dairy cattle in 3 or above 3 pregnancies group (1.52%), followed by 1 pregnancy group (4.27%) had nearly 3 times (OR=2.89, 95% CI, 1.11-7.52, P = 0.03) higher risk of being seropositive compared to dairy cattle in 3 or above 3 pregnancies group, although no statistical difference was found between 2 pregnancies group and 3 or above 3 pregnancies group (P = 0.70). The results of this survey indicated the presence of T. gondii infection in dairy cattle in Gansu Province and NXHAR, which enriches the epidemiological data of T. gondii infection in dairy cattle in China, and is helpful to strengthen prevention and control of T. gondii infection in dairy cattle in these two regions.

Oral cancer is a subset of head and neck cancer and usually refers to different neoplastic conditions that impact any tissue within the oral cavity. Evidence shows that these malignancies are associated with different complications over the affected patients. The present literature review will discuss the epidemiology and types of oral cancer based on evidence from relevant studies within the literature. Estimates show that oral cancer is a common condition with high prevalence rates globally. However, we have identified several factors across the different relevant investigations, including smoking, alcohol intake, age, socioeconomic status, immunocompromised state, and genetics. This might explain the inconsistent findings regarding the prevalence and mortality rates of the conditions among worldwide studies. Moreover, squamous cells carcinoma is the commonest type of oral cancer. However, other types might also be identified as adenocarcinoma, sarcoma, melanoma, and lymphoma. These lesions can also be found at different places within the mouth cavity, including lips, tongue, and salivary glands. Therefore, healthcare authorities should plan adequate interventional strategies targeting the risk factors to properly control the disease and reduce its burden.

The purpose of the current research was to determine the prevalence and risk factors linked to intestinal parasites in a population aged from 5 to 14 years who attend to public schools and high schools from Riobamba city, Riobamba-Chambo district. The prospection was carried out between October and November 2015. The population studied was identified and classified according to their age, gender, and educational institution they belong to. In addition, the relation of risk factors linked to the identified parasites was estimated. For this, it was necessary to apply a coprology examination to 2020 boys, girls and teenagers. The fecal samples collected were analyzed using the fresco technique with lugol and saline solution at 0.85%. The total intestine parasite prevalence found was 35.1%. The highest parasite prevalence was detected in groups aged 5 (12.84%), in groups aged 8 (11.71%) and in groups aged 11 (11.56%), while Combatientes de Tapi Educational Unit registered a 34% in both genders. Any significant parasite difference was found among p<0.05 ages. Nine parasite types were identified with Entamoeba coli prevalence (26%) Entamoeba histolytic (9.3%), Iodamoeba bütschlii (0.8%), Giardia lambia (4.3%), Chilomastix mesnilii (0.9%), Hymenolepis nana (1.4%), Ascaris lumbricoides (0.3%) Trichuris trichiura (0.5%), Endolimax nana (1.6%), from which protozoan were the predominant, some poly parasite samples were also found, it was determined that the sample studied reflects a high prevalence of intestinal parasites.
