Intestinal lymphangiectasia is a pathological dilation of enteric lymphatic vessels resulting in lymph leakage to the intestinal lumen. This chronic lymph leakage leads to a state of immunosuppression secondary to the loss of humoral and cellular components of the immune system and represents a potential risk factor for opportunistic infections. We report a case of protein-losing enteropathy in a seemingly immunocompetent patient. An intestinal histopathological study revealed the unusual association of lymphangiectasia and intestinal cryptococcosis. Although cryptococcal infection is common in immunocompromised patients, intestinal involvement is rarely reported. We found no reports on the association of intestinal cryptococcosis in patients with lymphangiectasia. This case report is the first to describe intestinal cryptococcosis associated with intestinal lymphangiectasia.

HIV is a human immunodeficiency virus, a retrovirus that causes AIDS in the event of untreated infection. The virus causes the weakness and inability of the organism's defense system. HIV disease is a chronic progressive process that begins with the onset of HIV virus into the body, and over time (in adults over 10 years), a gradual destruction of the immune system occurs. The host during the infection becomes vulnerable and is suffering from complications of opportunistic infections and malignancies. A person infected with HIV feels good until developing AIDS, does not notice any changes in health, and has no specific external signs of infection. The only way to detect infection at this stage is HIV testing. HIV is transmitted: unprotected sexual intercourse with the infected person, exchange of needles, syringes or accessories with infected persons when taking drugs, with infected mother on her baby before, during or after delivery (breastfeeding).

Background: Biofilm is a bacterial way of life prevalent in the world of microbes; in addition to that it is a source of alarm in the field of health concern. Pseudomonas aeruginosa is a pathogenic bacterium responsible for all opportunistic infections such as chronic and severe. Aim of this study: This paper aims to provide an overview of the promotion of isolates to produce a biofilm in vitro under special circumstances, to expose certain antibiotics to produce phenotypic evaluation of biofilm bacteria. Methods and Materials: Three diverse ways were used to inhibited biofilm formation of P.aeruginosa by effect of phenolic compounds extracts from strawberries. Isolates produced biofilm on agar MacConkey under certain circumstances. Results: The results showed that all isolates were resistant to antibiotics except sensitive to azithromycin (AZM, 15μg), and in this study was conducted on three ways to detect the biofilm produced, has been detected by the biofilm like Tissue culture plate (TCP), Tube method (TM), Congo Red Agar (CRA). These methods gave a clear result of these isolates under study. Active compounds were analyzed in both extracts by Gas Chromatography-mass Spectrometry which indicate High molecular weight compound with a long hydrocarbon chain. Conclusion: Phenolic compounds could behave as bioactive material and can be useful to be used in pharmaceutical synthesis. Phenolic contents which found in leaves and fruits extracts of strawberries shows antibacterial activity against all strains tested by the ability to reduce the production of biofilm formation rate.

Mycobacterium Spp

In recent years, non-tuberculous mycobacteria (NTM), once considered merely environmental saprophytes, have emerged as a major cause of opportunistic infections. There is no evidence of human-to-human transmission but they have been found in several environmental water samples. It is, therefore, of the utmost importance to develop methods of rapidly and accurately detecting non-tuberculous mycobacteria in water samples. To obtain a maximum recovery rate and a reduction of Mycobacterium spp. detection time in water samples, different decontamination, enrichment procedures and antibiotics supplements were tested before the inoculation into the Bactec® system. The proposed method of sample treatment (decrease in the decontamination time, followed for a peptone pre-enrichment step and an aztreonam and cefepime supplement) before the inoculation into the Bactec® system proved to be a good option for reliable and fast detection of Mycobacterium spp. in water samples.

Background: Fungal infections are opportunistic infections that become a serious problem to human health. Objective: Considering the antifungal potential of triazole nucleus, the study was carried out with the objective to synthesize some novel triazole derivatives with antifungal potential. Method: 1,2,4-triazole derivatives were synthesized via a two step reaction (reported earlier). The first step involves reaction of substituted benzoic acid with thiocarbohydrazide to form 4-amino-3-(substituted phenyl)-5-mercapto-1, 2, 4-triazole derivatives (1a-1k) while in second step, synthesized compounds (1a-1k) were then subsequently treated with substituted acetophenone to yield substituted (4-methoxyphenyl-7H-[1, 2, 4] triazolo [3, 4-b][1,3,4] thiadiazine derivatives (2a-2k). All synthesized compounds were characterized by IR, 1H NMR, and Mass spectral data analysis and were screened for their antifungal properties against different fungal strains i.e. Candida tropicalis (ATCC-13803, ATCC-20913), Candida albicans (ATCC-60193), Candida inconspicua (ATCC-16783) and Candida glabrata (ATCC-90030, ATCC-2001). Results: Compound 2d displayed better percentage inhibition (26.29%, 24.81%) than fluconazole (24.44%, 22.96%) against ATCC-16783, ATCC-2001 fungal strains respectively at 100µg/ml. Compound 2f also displayed better percentage inhibition (28.51%) against ATCC-90030 as compared to fluconazone (27.4%) at 200 µg/ml. Similarly, compounds 2e and 2j also exhibited better antifungal properties than fluconazole at 200µg/ml. Compound 2e was found most potent against ATCC13803 (30.37%) and ATCC-90030 (30.37%) fungal strains as compared to fluconazole (28.14%, 27.4%) at 200 µg/ml respectively whereas compound 2j exhibited better antifungal activity (28.51%) against ATCC-60193 than fluconazole (27.7%) at 200 µg/ml. Conclusion: The results were in accordance with our assertions for triazole derivatives, as all compounds displayed moderate to good antifungal activity.
