Seropositivity of Toxoplasma gondii in domestic animals.

Serum samples from 107 goats, 40 sheep, 50 cows were tested for Toxoplasma gondii antibody by indirect haemagglutination test (IHA) in dilutions of 1:10, 1:54, 1:162 and 1:486. Toxoplasma gondii-antibodies were found in 21 (19.6%), 10 (25%), 26 (52%), goat, sheep and cow sera respectively. No serum sample showed a titre higher than 1:162. All animals were kept in good hygienic condition. These results indicate that Toxoplasma gondii antibodies are widespread in animal populations which supports that toxoplasmosis is a widely spread zoonotic infection in this country.

Human pneumocystosis.

Pneumocystis is an atypical fungus causing pneumonia in immuno-compromised individuals. Though previously termed as Pneumocystis carinii, the recent taxonomy has considered human derived Pneumocystis to be a different species Pneumocystis jiroveci. The organism is the most common cause of opportunistic infections among patients with acquired immunodeficiency syndrome (AIDS) in developed countries. Incidence of Pneumocystis pneumonia or pneumocystosis in developing countries including India continues to be low. Microscopy of appropriate clinical samples has been the mainstay of diagnosis of pneumocystosis. Amplification techniques are now being evaluated for detection of P. jiroveci. This review attempts to give a recent update on P. jiroveci with special focus on epidemiology, taxonomy, current diagnostic modalities and recommended immuno-prophylaxis.

Detection of Entamoeba histolytica using polymerase chain reaction in pus samples from amebic liver abscess.

BACKGROUND AND OBJECTIVE: Direct demonstration of Entamoeba histolytica by conventional microscopy and in vitro culture in pus obtained from amebic liver abscess (ALA) is often unsuccessful. We evaluated polymerase chain reaction (PCR) for detection of E. histolytica DNA in such pus. METHODS: Species-specific primers were used for the amplification of E. histolytica DNA from liver pus obtained from 30 patients with ALA. Patients with pyogenic liver abscess and sterile (autoclaved) pus spiked with Entamoeba dispar and bacteria (Escherichia coli, Klebsiella spp. and Bacteroides spp.) were used as negative controls. RESULTS: PCR was positive in 83% of pus specimens from patients with ALA, and was negative in all 25 pus specimens obtained from pyogenic abscess and autoclaved pus spiked with known bacteria. Sensitivity and specificity of PCR were 83% and 100%, respectively. The overall positivity of PCR was higher compared to serological tests. CONCLUSION: PCR may be a more reliable and better alternative diagnostic modality for ALA.

Trichuris vulpis infection in slum children.

Trichuris vulpis was identified in two children from urban slums. Both of them had nonspecific abdominal pain and one had episodes of diarrhea. Clinical recovery was good after treatment with mebendazole.

Acute clonorchiasis in a child.

Clonorchiasis usually presents with chronic gastrointestinal disturbances or cholangiocarcinoma. We describe a rare acute presentation of clonorchiasis in a child with diarrhea and liver abscess.
