Epidemiological aspects and clinical implications of malaria as seen in Jeddah, Saudi Arabia.

A review is presented of 242 patients with acute malaria seen at two hospitals in Jeddah. Jeddah should be regarded as the malaria outpost of the South Western region of Saudi Arabia since nearly all of these patients contracted the disease while travelling within that area during the previous month. Plasmodium falciparum was the predominant infection (77%). There was a marked seasonal incidence with a peak during December to April; 84% of the patients were male. In contrast to the common impression that the total white cell count is low or normal in malaria, one-third of a sample of 124 patients had a total count of at least 10 000 mm-3; approximately 40% of the patients did not have a palpable spleen. Evidence is presented to show the danger of treating patients with falciparum malaria on an out-patient basis. Ideally, all such patients should be hospitalized and observed in order to ensure effective treatment. The Kingdom of Saudi Arabia has many medical and paramedical personnel who have little practical experience in the diagnosis of malaria. We therefore recommend that training programmes in the laboratory diagnosis of malaria should be initiated in specialized centres in the Kingdom or abroad.

The role of non-biting flies in the transmission of enteric pathogens (Salmonella species and Shigella species) in Beirut, Lebanon.

In the summer and early autumn of 1974, flies were trapped in the Beirut districts of Ashraffiyah, Burj, Burj-Hammoud, Quarantine, the New Slaughter House, Ras Beirut, American University Campus, and the suburbs of Chiyah and Mreyjieh. Musca domestica, Muscina stabulans, Calliphora vicina, Phormia regina, Phaenicia sericata, Sarcophagidae spp. and Fannia canicularis were identified. The rural areas of Mreyjieh and Chiyah had higher densities of Musca domestica while higher densities of Calliphoridae spp. were found in the Slaughter House, Quarantine and Burj-Hammoud districts. Twenty-nine isolates, ten of Shigella spp. and 19 of Salmonella spp. were obtained from the bacteriological studies of 72 batches of Muscidae spp. and 84 Calliphoridae spp. These results indicate the hyperendemicity of salmonellosis and shigellosis in the areas under study, due to the prevalent poor sanity conditions and high fly infestation. It is suggested that in countries where valid health statistics are not available, bacteriological studies of flies may provide essential epidemiological information.

Studies on naturally occurring filarial infections in dogs in Lebanon. I. Dipetalonema reconditum.

A survey for filarial parasites was carried out on dogs in Lebanon. The peripheral blood was examined for microfilariae and the skins and carcasses for adult worms. Three methods were used for blood examination: (a) thick blood films stained with Giemsa; (b) a modified Knott's technique (Methylene Blue stained); (c) sodium citrate technique. Two species of filarial worm were found, Dipetalonema reconditum and another species of Dipetalonema which will be described in a later paper. The morphology of microfilariae and adults of D. reconditum is described. The microfilariae of D. reconditum showed a nocturnal sub-periodicity. Attempts were made to find vectors by feeding Aedes aegypti, Aedes phoeniciae, Culex pipiens molestus and Clenocephalides felis on an infected dog. Developing and infective stages were recovered only from C. felis.
