“…There is a significant statistical (p<0.05) difference between prevalence and doe age in this study, and this agrees with the findings of several studies that reported that young animals are more vulnerable to T. gondii infections than older animals [31][32][33][34]. This may indicate the dominance of maternally acquired antibodies in the early stage of goats, unless re-infected, lessening antibodies as their age rises [29]. Our findings disagreed with that of Saeed et al [30], who reported that older animals are more susceptible than young animals to T. gondii infection due to continuous exposure to risk factors for a longer period in older animals.…”

Background and Aim: Toxoplasma gondii is a protozoan parasite that is responsible for the major cause of congenital diseases, abortion, and stillbirth in humans and farm animals. Primary infection in pregnant goats due to T. gondii leads to abortion and significant economic losses in the livestock industry. Moreover, very few studies have been performed for the identification of T. gondii from aborted fetuses of goats. The study was conducted for the molecular identification of Toxoplasma gondii from aborted fetuses of goats in Chattogram, Bangladesh. Materials and Methods: Twenty aborted fetuses of goats were collected from 52 farms in the study area. A nested polymerase chain reaction (PCR) assay targeting the B1 gene was performed, and a positive sample yield of 197 bp amplified DNA products consistent with T. gondii. Results: The overall prevalence of toxoplasmosis in the aborted fetus of goats was 35.0%. Heart muscle, liver, brain, and placenta showed positive PCR results. The risk factors related to the does age, presence of cats in farms, and aborted fetus age were found to be statistically significant (p<0.05). Our results showed that T. gondii is a major possible causal factor for abortion and reproductive failure in goats. The high prevalence of T. gondii infection in aborted fetuses of goats revealed that T. gondii could be imperative in causing reproductive failure in goats. Conclusion: Active or congenital toxoplasmosis was shown by the presence of T. gondii in fetal tissues, which is a matter of concern as this parasite has zoonotic significance and causes economic hazards to the livestock industry by causing various reproductive problems. Therefore, proper control measures and strategies are needed to reduce the rate of abortion in goats, ultimately saving the livestock industry.

“…This result showed clearly the existence of T. gondii infection in sheep and goats in Benghazi and the nearby areas and they are more at risk to T. gondii infection hence the meat from such animals could be a potential risk to public health if consumed raw or undercooked. The latex agglutination test (LAT) is easy to perform, sensitive and has been used for the measurement of antibodies to T. gondii in serum of sheep, goats, pigs, camels, donkeys, humans, and cattle (Al-Ramahi, Hamza and Abdulla, 2010; Younis et al, 2015;Fereig et al, 2016;Atail et al, 2017;Ishaku et al, 2018;Etter, Neves and Tagwireyi, 2019;Julie, Paul and Antoine, 2019). The high overall seroprevalence (55.3%) recorded in this study is consistent with results reported by many authors from different parts of the world (Hove, Mukaratirwa and Lind, 2005;Atail et al, 2017;Etter, Neves and Tagwireyi, 2019).…”

In this study, serum samples from four hundred and seventy (470), comprising 234 local sheep (Ovis aries) and 236 goats (Capra aegagrus hircus) of different ages and gender were collected and analysed for Toxoplasma gondii antibodies (IgG) using the latex agglutination test (LAT) kits according to manufacturer’s instructions. The result showed that of the 470 serum samples of tested animals (sheep and goats) analysed, 260 were positive for Toxoplasma gondii antibodies (IgG) given an overall prevalence of 55.3%. A significant difference in seroprevalence of T. gondii antibodies was observed between the two species of tested animals with a higher prevalence in sheep (P=0.02). No significant differences in the overall seroprevalence of T. gondii antibodies between males (61.5%) and females (45.5%) of both species (P=0.339). The overall seroprevalence of T. gondii was higher in tested animals of less than 2 years of age, though the difference was not statistically significant (p=0.225). According to the breeding site, Almagzha region showed significant (P=0.00) high seroprevalence (77.4%) compared with other sites. The highest T. gondii seroprevalence was recorded in the spring season. This study showed that local sheep and goats from Benghazi and the near by areas may represent a significant source of T. gondii infection in the human population through consumption of undercooked meat.

“…Efforts have been made to isolate the T. gondii tachyzoites from the saliva, urine, vaginal mucosa and nasal secretions of infected food animals [12]. Consumption of products, including milk, from diseased food animals stands as an imperative cause of human infection, which is of concern due to a rise in the consumption of sheep and goat's milk among children with an allergy to cow's milk [13].…”

Toxoplasmosis is a globally distributed disease of warm-blooded animals. It is caused by the opportunistic parasite Toxoplasma gondii (T. gondii). One-third of the global human population is believed to be infected with T. gondii. Cats serve as final host of T. gondii and are the main source of contamination of soil and water. This study aimed to detect genotypes of T. gondii in cats. Fecal samples (n = 400) were collected from districts of South Punjab (Khanewal and Sahiwal), and were processed by polymerase chain reaction (PCR) followed by sequencing and phylogenetic analysis. The obtained oligonucleotide sequences (T. gondii) were submitted to the GenBank database, and the evolutionary tree was constructed using MEGA-X software. Seven fecal samples (3.5%) from cats were positive. Five out of thirteen fecal samples (38.46%) found to be positive for T. gondii with microscopy were confirmed by PCR. After phylogenetic analysis with 3 clonal types and atypical strains, isolates of T. gondii in current study were more closely linked to a typical strain (AF249696). Besides genotyping from cats, seroprevalence from humans and ruminants is still considered to be the best and easiest way to identify the Toxoplasma. Blood samples were collected from sheep and goats (n = 2000 each), and human blood samples (n = 400) were collected from the same vicinity. Seroprevalence was determined using a commercial enzyme-linked immunosorbent assay (ELISA) kit. In Khanewal, the blood samples of 292 goats (29.2%) and 265 sheep (26.5%), and 6 fecal samples from cats (3%) were positive. Out of 200 human blood samples, 52 were positive, with a seroprevalence of 26%. In the Sahiwal district, the blood samples from 49 humans, 235 sheep and 348 goats were positive, with seroprevalence of 24.5%, 23.5% and 34.8%, respectively. The present study revealed the current circulating genotype of T. gondii from cats in the districts Khanewal and Sahiwal and the seroprevalence of the organism in small ruminants and humans living in the same vicinity. Further genotype analyses of the organism from ruminants and humans are needed.
