“…The 2.67% incidence in this investigation is higher than 1.9% and 2.1% in Bauchi zone but lower than 4% found in Kaduna and Zaria (Guinea zone) (Dada, 1980) . This could be as a result of improvement in the number of veterinary personnel, actual technique of meat inspection, the recording system and abattoir facilities.…”

The incidence of infection due to Cysticercus bovis in Kano abattoir located in Fagge local government area (LGA) of Kano state, Nigeria was studied. Out of the 11,804 cattle which were examined, 315 (2.67%) were found to be infected. The tongue, cardiac and masseter muscles were the main predilection sites of the cysts. The relative occurrence of the cysts in the organs of infected catteles showed tongue (76%), heart (66%) and masseter (63%) had the highest rate of infestation. There was no significant difference (p>0.05) in the distribution of the cysticerci in the organs of cattle slaughtered at the abattoir. The results also show 205 (0.37%) and 304 (0.55%) head and heart condemnations respectively. This information is considered useful for government authorities to direct control strategies as well as for farmers to take measures tailored to local situations.

“…In humans, information on cystic echinococcosis is rather scarce. Although where available, low prevalence is commonly reported and has been attributed to the use of less sensitive diagnostic tools [28] or the fact that CE is not considered during routine medical examination. Till now, human CE has been investigated in few states and are mostly retrospective studies involving assessment of hospital records [28,61] (Table 2).…”

Till now, human CE has been investigated in few states and are mostly retrospective studies involving assessment of hospital records [28,61] (Table 2).

Purpose Cystic echinococcosis (CE) caused by Echinococcus granulosus sensu lato is a widespread zoonotic disease of global concern. In Nigeria, the exact picture/status of CE is unclear, as most of the states are largely uninvestigated. Yet, as with every parasitic zoonosis, the first step towards planning a comprehensive management and control programme involves assessment of available national/regional prevalence data, host range, and risk factors at play in the transmission dynamics. Methods Published articles on echinococcosis were searched on PubMed and Africa Journal Online (AJOL) databases. Inclusion criteria were based on studies reporting prevalence of echinococcosis in animals and humans (including case reports) from 1970 to 2018. Results In this study, we evaluated and summarized cystic echinococcosis reports in Nigeria and found that post 1970-80s, studies on cystic echinococcosis have remained sparse regardless of the high prevalence recorded in the early years of CE investigation. In addition, information on the genetic population structure and the role of wildlife in CE transmission is still lacking. Conclusions This study appraises the prevalence and distribution of CE in Nigeria and identified areas where surveillance and control efforts should be focused and intensified.

Cystic echinococcosis (CE) is a globally endemic zoonosis caused by the larval stage of the sensu lato (s.l.) complex. Although the disease is known to be highly prevalent in certain parts of North and East Africa, data on CE, both in humans and definitive hosts, are extremely scarce for Central Africa. The present study assessed the epidemiology of CE in humans and dogs in rural Gabon. An ultrasound and serologic survey was conducted in volunteers from rural villages in Gabon. A two-step approach was used for serological testing with an indirect hemagglutination assay as a screening test and Western Blot as a confirmatory test. Fecal dog samples were analyzed microscopically, and polymerase chain reaction (PCR) amplification of and genes was performed when taeniid eggs were visible. Regional hospitals and the national reference center for parasitology in Gabon were contacted for information about previous cases of CE. Randomly selected communities were invited to participate. Three hundred and forty-eight human volunteers from these communities were screened. No suspected cases of CE were detected. Definitive host screening was performed from 128 fecal samples from representative subregions, but no eggs from s.l. were found. No documented cases of echinococcosis were reported from the local health-care institutions and the national diagnostic reference center in Gabon. Cystic echinococcosis seems to be very rare or absent in Gabon. The reason for this lack of evidence for echinococcosis is unknown, but the absence of livestock may play a major role.
