“…Cerebral malaria (CM) is a complication of P. falciparum infection in humans and is characterized by a reversible encephalopathy with seizures and loss of consciousness. Central clinical signs are partly due to sequestration of parasitized red blood cells in the brain microvasculature due to interactions between parasite proteins and adhesion molecules [28,37,38,39,40,41,42,49]. At Chikankata Hospital in rural Zambia, seizures comprised 44% of all inpatients presenting with neurological diseases and among these, children with FS had higher malarial parasite counts and required longer hospitalizations [50].…”

Epilepsy is a common neurological disorder; however, in Nigeria and other tropical regions, the causes of epileptic seizures differ greatly in etiology. This paper is an attempt to highlight some possible microbiological aspects of epileptic seizures. A literature review was carried out to identify the extent to which microbial infections were involved in the elicitation of epileptic seizures. Data were collected from several clinics in the community and hospitals in Nigeria and correlated with the evidence from the literature review. It was found that different microbial agents including viral, bacterial, protozoa, and fungal agents were involved in several aspects of epileptic seizures. Malaria was found to cause more than 88% of childhood epileptic seizures and 12% of adult seizures. Generalized tonic-clonic seizures occurred in more than 40% of adult patients. Partial seizures were uncommon. Cases of epileptic seizures associated with bacteria (e.g., brucellosis), viral, fungal, and protozoa infections were frequently reported. Malaria, tapeworm, and cysticercosis were some of the common infectious causes of epilepsy; however, in some cases, the cause remained unknown. From these findings, it was evident that microbiological aspects of epilepsies are possible research areas that might be developed. It is believed that the unraveling of the various microbiological factors in epileptic seizures would have important implications for understanding the underlying neurobiology, evaluating treatment strategies, and perhaps planning health-care resources for the affected. It will also help to improve the prognostic factors in initial seizure symptomatic etiology and presence of any structural cerebral abnormalities.

The survival of two economically important monogenean parasites, Benedenia seriolae and Zeuxapta seriolae, exposed to either naïve or infected yellowtail kingfish Seriola lalandi serum and mucus was observed over an 8-h period. Infection status of the host had no effect on survival of monogeneans in either serum or mucus therefore data were grouped according to each parasite. Serum exposure at the highest concentration of 1:5 did not have any effect on Z. seriolae, however, 50% killing activity against B. seriolae was observed within 3 h at concentrations greater than 1:100. This killing activity was completely abolished following heat treatment and inactivation of the serum. Prior incubation of parasites with heat-treated serum for 2 h in order to potentially coat the parasites with antibodies did not enhance the activity of fresh serum against either species. Addition of 5 mM EDTA, but not 5 mM EGTA-Mg, inhibited the killing ability of fresh serum against B. seriolae, suggesting that previously observed activity against this parasite was most likely mediated via the alternative complement pathway. Cutaneous mucus was not found to have any effect on B. seriolae or Z. seriolae survival. Overall these results suggest that the blood-feeding gill parasite Z. seriolae is considerably more resistant to host immune responses compared with skin-and mucus-dwelling B. seriolae.
